Description

Traffic information processing apparatus, processing method thereof, and program

The present invention relates to a traffic information processing apparatus that is installed in a vehicle or the like and processes traffic information such as a travel route of the vehicle, a processing method thereof, and a program.
This application claims priority on January 09, 2013 based on Japanese Patent Application No. 2013-001961 filed in Japan, the contents of which are incorporated herein by reference.

A car navigation device installed in a vehicle or the like receives a transmission signal transmitted from a GPS satellite, measures the current position of the vehicle, and identifies a road that is currently running. In addition, the car navigation device detects a virtual position corresponding to the actual current position of the vehicle on the identified road on the map displayed on the screen, and displays a mark indicating the current position of the vehicle at the virtual position. The processing to do.
A technique for displaying the current position on a map output on a display screen is disclosed in Patent Document 1.
In a complex road network where multiple routes from a specific entrance to a specific exit can be selected arbitrarily, the route that the vehicle actually traveled is automatically determined and the total distance of the traveled route is determined. Japanese Patent Application Laid-Open No. 2004-151867 discloses a technique that enables a toll to be calculated and charged accordingly.

JP 2008-134187 A Japanese Patent Laid-Open No. 9-212794

By the way, in Europe, Singapore, etc., it is considered to collect tolls by using a billing method called road pricing that charges tolls according to the road where the vehicle actually travels and the distance. In the road pricing, the travel route is specified based on the positioning result of the vehicle based on the signal received from the GPS satellite, and charging according to the travel distance on the travel route is scheduled.

In such a charging technology called road pricing, a traffic information processing device such as a car navigation device detects a traffic point provided on a moving route due to a shift in a vehicle detection position due to a signal received from a GPS satellite. There is a case where it is erroneously detected that a plurality of passes. For example, the driver stops the vehicle engine before the traffic point and determines that the vehicle has not actually passed the traffic point and the traffic information processing device has not passed the traffic point. Assume that the power is turned off. In such a situation, when the driver starts the engine of the vehicle again, the traffic information processing apparatus is turned on and detects the position of the vehicle. At this time, if the position of the vehicle first detected after the power is turned on in the traffic information processing apparatus erroneously detects a point ahead of the passing point as the position of the vehicle, it is not determined that the passing point has passed. It will be. When the passing point is a point where the charging amount is applied to the vehicle, there is a problem that the charging amount at the time of passing the passing point is not added to the calculation of the charging amount of the moving route of the vehicle.

Also, for example, after the vehicle has actually passed the passing point, the position where the driver has passed the passing point in a situation where the traffic information processing apparatus determines that the passing point has passed and the information of the passing point is stored. Then, the vehicle engine is stopped and the traffic information processing apparatus is turned off. In such a situation, when the driver starts the engine of the vehicle again, the traffic information processing apparatus is turned on and detects the position of the vehicle. At this time, if the position of the vehicle first detected after the power is turned on in the traffic information processing apparatus erroneously detects a point that has already passed without passing the passing point as the position of the vehicle, the vehicle position from that point is again detected. It may be determined that the same passing point has been passed twice by detecting the movement. When the passing point is a point where the charging amount is applied to the vehicle, there is a disadvantage that the charging amount when the passing point passes is added twice to the calculation of the charging amount of the moving route of the vehicle.

Therefore, there is a need for a technique that does not perform such a passage point omission determination omission or an illegal multiple pass point determination process.

FIG. 2 is a first diagram illustrating a processing flow of the traffic information processing apparatus 1.
Hereinafter, the details of the processing of the traffic information processing apparatus 1 will be described in order. In the following description, “input” means that a processing unit “acquires” information output from another processing unit.
First, the position information calculation unit 15 of the position measurement unit 10 inputs information from sensor devices such as a latitude / longitude measurement sensor 11, an acceleration sensor 12, a gyro sensor 13, and a vehicle speed signal output device 14 according to the movement of the vehicle. The vehicle's sensing position (latitude and longitude) is calculated (step S101). Then, the position information calculation unit 15 outputs the calculated sensing position (position sensing information) to the map matching unit 20. In the map matching unit 20, the real-time processing unit 21 inputs the sensing position of the vehicle.

Here, the real-time processing unit 21 records the road (road ID) existing at a position within the error range from the sensing position based on the sensing position of the vehicle input from the position positioning unit 10 in the storage unit 50. Identify from multiple road information. Then, the real-time processing unit 21 specifies the current position, traveling direction, and speed that can be estimated as the most likely (appropriate) position on the road based on the sensing position (step S102). Note that the current position that can be estimated as the most likely (appropriate) position on the identified road can be, for example, a position closest to the sensing position on the identified road. Alternatively, the current position may be specified using information on the traveling direction and speed in addition to the sensing position. The road information recorded in the storage unit 50 includes the position information of the end points of the road indicated by the road information, the position information for each predetermined interval on the line connecting the end points, the information on the extending direction of the road, and the like. It may be. Then, the real-time processing unit 21 outputs the current position on the road of the vehicle and the road ID (road identification information) to the application unit 30 in real time. Note that the real-time processing unit 21 may also output the current position on the road of the vehicle and the road ID to the travel route specifying unit 22.

Next, the first passage point passage determination unit 301 of the application unit 30 inputs the current position specified by the real-time processing unit 21 and the road ID indicating the road on which the vehicle is traveling. Then, the first passing point passage determination unit 301 reads the ID of one or more passing points recorded in the storage unit 50 in association with the input road ID and the position information of the passing points from the storage unit 50. . Then, the first passage point passage determination unit 301 identifies the position information of the passage point closest to the current position among the read passage point position information, and the current position and the position information of the identified passage point are determined. Calculate the distance. Then, the first passing point passage determination unit 301 determines whether the vehicle has passed the passing point based on the distance between the current position and the position information of the specified passing point (step S103). For example, the first passage point passage determination unit 301 passes the passage point when the distance between the current position and the position information of the identified passage point is equal to or less than the distance at which it can be determined that the passage point has passed. judge. If the first passage point passage determination unit 301 determines that the passage point has not been passed, the first passage point passage determination unit 301 waits for the input of the current position from the real-time processing unit 21. If the first passage point is input, step S103 is performed again. Judgment is made.

When the first passing point passage determining unit 301 determines that the passing point has been passed, it outputs a road type determining request for the road on which the vehicle is currently traveling to the moving route type determining unit 307. The road type determination request includes the road ID input from the real-time processing unit 21. The movement route type determination unit 307 reads the road type information associated with the road ID and recorded in the storage unit 50 to determine the road type (movement route type) (step S104). Information is output to the first passing point passage determination unit 301.

Next, the first passing point passage determining unit 301 requests the passing point type determining unit 303 to determine the type of the passing point. The type determination request signal includes a passing point ID. When the type determination request is input, the passing point type determination unit 303 determines whether the passing point determined to have passed is a confirmed point or a non-determined point (step S105). More specifically, the passing point type determination unit 303 reads from the storage unit 50 information on the type of the passing point recorded in association with the ID based on the ID of the passing point determined to have passed. Then, the passing point type determination unit 303 determines whether the information on the type of the passing point read from the storage unit 50 is information indicating a confirmed point or information indicating a non-determined point. Then, the passing point type determination unit 303 outputs information on the determination result indicating either the confirmed point or the non-determined point to the first passing point passage determination unit 301.

Then, when the determination result from the traffic point type determination unit 303 is information indicating a confirmed point, the first traffic point passage determination unit 301 immediately transmits information indicating the traffic point passage to the first traffic point passage information output unit. It outputs to 302 (step S106). Then, the 1st passage point passage information output part 302 displays the passage information which shows having passed the passage point on the display part 40 (step S107). At this time, the first passing point passage information output unit 302 also acquires the name of the passing point based on the ID of the passing point, information on the type of the passing point, and the like from the first passing point passage determination unit 301. You may make it output to the display part 40. FIG. The passage information or the like may be displayed on the liquid crystal display unit as a character string, or a lamp for notifying the driver of the vehicle that a certain passing point has been passed may be turned on. Alternatively, instead of the display unit 40, the voice output unit may output that the passage point has been passed by sound.

The first passage point passage determination unit 301 outputs information indicating passage of passage points to the first passage point passage information output unit 302, and then outputs a request for specifying a movement route that has passed in the past to the movement route specification unit 22. The movement path specifying request is a signal for requesting the moving path specifying unit 22 to forcibly determine the past moving path up to the passing point. As a result, the traffic information processing apparatus 1 displays on the display unit 40 information indicating that the passage point has been passed and information on the charge amount up to the passage point based on the confirmation of the movement route when the passage point is passed. Can be output. The travel route specifying request includes the current time, the road ID input from the real-time processing unit 21, the road type determined in step S104, the type of the traffic point determined in step S105, the ID of the traffic point determined in step S105, and the like. May be included. It is assumed that the ID of the passing point is read by the first passing point determination unit 301 from the storage unit 50. Then, the movement path | route specific | specification part 22 determines the movement path | route which passed in the past (step S108). Details of this processing will be described later.

The process of specifying the movement route is a process of specifying a road that has traveled in the past with higher accuracy, unlike the specification of the road performed based on the current position of the vehicle in the real-time processing unit 21. More specifically, the moving route specifying unit 22 estimates estimated moving route information excluding estimated moving route information determined not to be a moving route from estimated moving route information including road IDs indicating a plurality of previously estimated moving routes. Is a processing unit that determines and outputs the road ID included in the road ID indicating the past travel route. By performing such a process, it takes some time to determine that the travel route has passed in the past, compared to the time required for the road specifying process in the real-time processing unit 21. When the travel route specifying unit 22 determines the travel route that has passed in the past up to the travel point determined to have passed in step S103, the travel route specifying unit 22 determines the type of the travel point included in the request for specifying the travel route (step S109). ). Then, when the type of the traffic point indicates a fixed point, the travel route specifying unit 22 sends a charge amount calculation request for instructing to calculate the charge amount in the past travel route to the travel point to the charge amount calculation unit. To 304. The charge amount calculation request includes a road ID of a road newly identified as a road on the movement route among the road IDs of roads indicating a movement route to a passing point determined to have passed, and a request for specifying a movement route. It is assumed that information such as the included road type, the type of passing point, and the ID of the passing point is included.

Then, the billing amount calculation unit 304 inputs the road ID, the road type, the type of the passing point, the ID of the passing point, the ID of the passing point that has been input in the past, The billing amount is calculated using the information on the road type, the type of passing point, and the ID of the passing point (step S110). More specifically, based on a plurality of road IDs and road types of the road IDs, the distance of the road and the charge amount when traveling on the road are read from the storage unit 50, and the type of the traffic point and the traffic point Based on the ID, the charge amount when the passing point is passed from the storage unit 50 is read. Then, the sum of those billing amounts is calculated. Alternatively, the charge amount calculation unit 304 may calculate the sum of the charge amount calculated in the past and the charge amount on the travel route newly calculated this time. Then, the billing amount calculation unit 304 outputs the calculated billing amount to the display unit 40 (step S111). The charge amount may be displayed as a character string on the liquid crystal display unit, or instead of the display unit 40, the voice output unit may output a voice indicating the charge amount by sound.

According to the above-described processing, a traffic point belonging to a fixed point whose billing amount is determined only by passing through the traffic point (a traffic point for performing point billing, a traffic point for performing coden billing, a target for highway billing) When the vehicle passes a traffic point provided at the exit of the road, a traffic point provided at the exit of the road subject to distance billing, etc., information indicating that the vehicle has passed immediately is displayed on the display unit 40. Output. Thereby, the driver of the vehicle can recognize in real time that the road where the road pricing is applied has passed the passing point where the billing amount is determined only by passing even if there is no large mark. In addition, when the vehicle passes the passing point belonging to the confirmed point, information indicating that the passing point has been output is output to the display unit, and then the process of step S108 is performed until the position of the passing point belonging to the confirmed point. A high-accuracy travel route is specified, and the charge amount determined using the highly accurate travel route is output to the display unit 40. As a result, the driver can immediately recognize the charged amount with high accuracy at the stage of passing the passing point belonging to the fixed point. In addition, although it takes time to determine the past movement route in the movement route specifying unit 22 as compared with the real-time processing unit 21, the difference is about 1 second. This difference in processing time is a time difference in which the driver passes through the passing point to be charged and the amount of money charged up to the passing point is output to the display unit 40 without any discomfort.

In the above-described step S105, when it is determined that the passing point that has passed is not a fixed point for determining the billing amount when it is detected that the passing point has been passed, the first passing point passage determining unit 301 performs step S106. The process waits until the next information (current position, road ID) from the real-time processing unit 21 is input without performing the process of outputting the information indicating the passing of the passing point to the first passing point passing information output unit 302. The process from step S102 is repeated.

FIG. 3 is a second diagram illustrating a processing flow of the traffic information processing apparatus 1.
In the map matching unit 20, the movement route specifying unit 22, based on the processing result of the real-time processing unit 21, in the past, regardless of whether the movement route specifying request is input from the first passing point passage determination unit 301. The process of determining the travel route that has passed is performed at predetermined timing intervals. However, the movement route specifying unit 22 inputs the movement route specification request input from the first passing point passage determination unit 301, and determines the movement route that has passed in the past even at the timing when the specification request is input. A passage point passage determination request is output to the two passage point passage determination unit 305. Then, the second passage point passage determination unit 305 inputs a passage point passage determination request (step S201). The passage point passage determination request includes a road ID indicating a confirmed movement route that has been confirmed to have passed in the past and a current position (for example, a position that is estimated to be the most likely (appropriate) position on the road with the confirmed road ID). Contains information.

Next, the second passage point passage determining unit 305 reads from the storage unit 50 the position information of the passage point that is associated with the input road ID and recorded in the storage unit 50. Then, the second passing point passage determination unit 305 identifies the position information of the passing point closest to the current position among the read position information of the passing point, and determines the current position and the position information of the identified passing point. Calculate the distance. Then, the second passing point passage determining unit 305 determines whether the vehicle has passed the passing point based on the distance between the current position and the position information of the specified passing point (step S202). For example, the second passage point passage determining unit 305 has passed the passage point when the distance between the current position and the position information of the identified passage point is equal to or less than the distance at which it can be determined that the passage point has been passed. judge. When the second passage point passage determination unit 305 determines that the passage point has not been passed, the second passage point passage determination unit 305 waits for input of the road ID and the current position from the movement route specifying unit 22 and inputs the road ID and the current position. In that case, the determination in step S202 is performed again.

When the second passing point passage determination unit 305 determines that the passing point has passed, the second passing point passage determination unit 305 requests the passing point type determination unit 303 to determine the passing point type. It is assumed that the type determination includes a passing point ID. When the type determination request is input, the passing point type determination unit 303 determines whether the passing point determined to have passed is a confirmed point or a non-determined point (step S203). More specifically, the passing point type determination unit 303 reads from the storage unit 50 information on the type of the passing point associated with the ID based on the ID of the passing point determined to have passed. Then, the passing point type determination unit 303 determines whether the information on the type of the passing point read from the storage unit 50 is information indicating a confirmed point or information indicating a non-determined point. Then, the passing point type determination unit 303 outputs information of a determination result indicating either a confirmed point or a non-determined point to the second passing point passage determination unit 305.

Then, the second passage point passage determination unit 305 determines that the determination result from the passage point type determination unit 303 is a non-determinable point (a traffic point provided at the entrance of the target road of the expressway, the entrance of the target road for distance charging) Only when it is information indicating a passing point provided in the information item, the information indicating that the passing point has passed is immediately output to the second passing point passing information output unit 306 (step S204). Then, the second passage point passage information output unit 306 displays passage information indicating that the passage point has passed on the display unit 40 (step S205). The passage information may be displayed as a character string on the liquid crystal display unit, or a lamp for notifying the driver of the vehicle that a certain passing point has been passed may be turned on. Alternatively, instead of the display unit 40, the voice output unit may output that the passage point has been passed by sound.

If the determination result from the passing point type determining unit 303 is information indicating a confirmed point, the second passing point passage determining unit 305 sends information indicating passing point to the second passing point passing information output unit 306. Do not output. This is because information indicating that the vehicle has passed by the first passage point passage determination unit 301 and the first passage point passage information output unit 302 is already displayed when the passage point belonging to the confirmed point is passed.

With the above processing, when the passing point of the vehicle is a non-deterministic point, the accuracy after the movement route specifying unit 22 of the map matching unit 20 performs the process of determining the movement route that has passed in the past. The information indicating whether or not the passing point on the moving route is currently passed is displayed using the higher latitude route. As a result, when passing a passing point, which is a non-determinable point whose charging amount is not determined only by passing, the passing timing can be notified with higher accuracy.

FIG. 4 is a diagram showing an outline of the passage point passage determination process.
FIG. 4A is a diagram illustrating an outline of passage point passage determination performed by the first passage point passage determination unit 301 and the second passage point passage determination unit 305 in Step S103 and Step S202 described above. In the passage point passage determination shown in FIG. 4A, the road ID input based on the result of the previous processing (previous map matching result) of the real time processing unit 21 of the map matching unit 20 and the movement route specifying unit 22 This is effective when the road ID input based on the result of the current process (the current map matching result) is the same. That is, it is effective when the vehicle is moving on the same road in the previous map matching process and the current map matching process performed at predetermined intervals. In such a case, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 use the road ID input based on the current map matching process to pass the road ID on the road. The position information of the passing point closest to the current position is read from the storage unit 50. The first passage point passage determination unit 301 and the second passage point passage determination unit 305 can determine that the passage point has passed if the read position information is within a predetermined distance from the current position.

On the other hand, FIG. 4B shows an example of passage determination when a passing point is present near the end of a road. Specifically, FIG. 4B shows an example of passage determination in a T-shaped road where a road with road ID = 1, a road with road ID = 2, and a road with road ID = 3 are connected.
Here, when the traffic point exists near the end of the road with the road ID = 1, the first traffic point passage determination unit 301 and the second traffic point passage determination unit 305 travel on the road with the road ID = 2. Consider a case in which the passage point passage determination as shown in FIG. In such a case, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 acquire only the information of the road ID (= 2) based on the result of the current map matching process. Then, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 acquire the position information of the passage point from the storage unit 50 based on the information of road ID = 2. However, in such processing, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 have not acquired the information of the road ID = 1, and therefore the traffic associated with the information of the road ID = 1. The point information cannot be acquired from the storage unit 50. Therefore, when the previous passage determination is performed near the center of the road with the road ID = 1 and the current passage determination is performed on the road with the road ID = 2, the road ID is between the passage determinations. = 1, when the vehicle has passed a passing point at the end of the road (the end on the road side of road ID = 2), the map matching process of this time is performed as shown in FIG. Even if an attempt is made to determine the passage of a passing point using only the road ID (ID = 2) acquired based on the result, a situation in which it cannot be determined that the passing point has passed will occur.

In order to solve such a problem, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 determine the result of the previous map matching process (determining whether the previous passage point has been passed or not). Whether the two road IDs of the road ID input based on the result of the current map matching process and the result of the current map matching process (the determination result of whether or not the vehicle has passed the current passing point) are different. judge. And when it is different (when it is detected that a plurality of travel routes are crossed), the first passage point passage determination unit 301 and the second passage point passage determination unit 305 are associated with the plurality of road IDs and are stored in the storage unit. The position information of the passing point recorded in the storage 50 is read from the storage unit 50. Thereby, in the road as shown in FIG. 4B, the position information of the traffic point on the road with the road ID = 1 and the traffic point on the road with the road ID = 2 can be read. Then, the first passage point passage determination unit 301 and the second passage point passage determination unit 305 specify the position information of the passage point closest to the current position among the read passage point position information, the current position, Calculate the distance from the location information of the specified passing point. And the 1st traffic point passage determination part 301 and the 2nd traffic point passage determination part 305 determine whether the vehicle passed the traffic point based on the distance between the current position and the position information of the specified traffic point. .
By such processing, when there is a passing point at the end of the road with road ID = 1 as shown in the upper part of FIG. 4B, and road ID = 2 as shown in the lower part of FIG. 4B. In any case where a traffic point exists at the end of the road, it can be determined that the vehicle has passed the traffic point. The first passage point passage determination unit 301 and the second passage point passage determination unit 305 may record information on the passage point determined to have passed and the time at which the passage point is determined to have passed in the storage unit 50. .

FIG. 5 is a third diagram showing a processing flow of the traffic information processing apparatus 1.
Next, processing when the traffic information processing apparatus 1 is turned off and then turned on will be described.
When the driver stops or parks the vehicle, the driver turns off the engine. At this time, in the traffic information processing apparatus 1, the operation stop time information recording unit 23 in the map matching unit 20 inputs an operation stop signal from an external device such as a vehicle control device that controls the vehicle, and the operation stop signal An operation stop is detected based on the input. Here, the operation stop time information recording unit 23 is the road ID of the road on which the vehicle last traveled on the travel route determined by the travel route specifying unit 22 at each processing timing repeatedly performed in each processing unit of the traffic information processing apparatus 1. And the current position when the operation is stopped is input from the real-time processing unit 21. Then, the operation stop time information recording unit 23 displays the latest road ID inputted when the operation stop is detected, the current position at the time of operation stop (detected position information at the time of stop), and the detection time of the operation stop. The associated stop time information is recorded in the storage unit 50.

And when the driver starts the vehicle, the engine is turned on. At this time, power is supplied to the traffic information processing apparatus 1. In the traffic information processing apparatus 1, after power is supplied, the operation start time information acquisition unit 24 first inputs an operation start signal from an external device such as a vehicle control device, and detects the operation start based on the input of the operation start signal. (Step S301). Then, the operation start time information acquisition unit 24 inputs the road ID (starting road identification information) of the movement route that is determined for the first time after the movement route specifying unit 22 detects the operation start, and also receives the latest current information from the real time processing unit 21. Enter the position (starting position information). Further, the operation start time information acquisition unit 24 acquires the time when the operation start is detected from RTC (Real Time Clock) or the like. The operation start time information acquisition unit 24 outputs the input road ID (start time road identification information) to the road identification information match determination unit 26. The operation start time information acquisition unit 24 outputs the input current position (start time detection position information) and the time when the operation start is detected to the passage determination cancel unit 28. Further, the operation start time information acquiring unit 24 stores start time information in which a road ID (start road identification information), a current position (start detection position information), and a time when the operation start is detected are associated with each other. Record 50.

Here, in parallel with the power supply to the traffic information processing apparatus 1, the second passing point passage determining unit 305 determines whether or not the passing point has passed. Then, the second passing point passage determination unit 305 reads the stop time information and the start time information from the storage unit 50. The second passage point passage determination unit 305 reads position information of a plurality of passage points recorded in the storage unit 50 in advance.

Then, the second passing point passage determination unit 305 uses the stop detection position information (latitude x1, longitude y1) included in the stop time information and the start detection position information (latitude x2, longitude y2) included in the start information. The distance between the connecting line segment and the position information of each passing point read from the storage unit 50 is calculated. Then, the second passage point passage determination unit 305 determines whether the vehicle has passed the passage point (step S302). The specific process of step S302 is as follows. First, the second passing point passage determination unit 305 connects the detection position information at the stop (latitude x1, longitude y1) and the detection position information at the start (latitude x2, longitude y2). It is determined whether the distance between the minute and the position information of any one of the passing points read from the storage unit 50 is less than a threshold value. Further, the second passage point passage determination unit 305 has a shortest line from the position indicated by the position information of the passage point read from the storage unit 50 to the line segment connecting the detection position information at the stop and the detection position information at the start. It is determined whether or not it is orthogonal to a line segment connecting the stop detection position information and the start detection position information. Then, the second passing point passage determination unit 305 detects the stop position detection position information from the position indicated by the passing point position information when the distance from the position indicated by the passing point position information to the line segment is less than the threshold. When the shortest line to the line connecting the start detection position information and the start detection position information is orthogonal to the line connecting the stop detection position information and the start detection position information, it is determined that the vehicle has passed the passing point. This process is for determining whether there is a passing point on the moving route of the vehicle connecting the detected position information (latitude x1, longitude y1) at the stop and the detected position information (latitude x2, longitude y2) at the start. It is processing. Thereby, it is determined whether or not a passing point existing on the moving route between the stop position information (latitude x1, longitude y1) and the start position information (latitude x2, longitude y2) has been passed. It is possible to prevent the passage point from being missed.
Note that the second passing point passage determination unit 305 may determine that the vehicle has passed the passing point immediately if the distance from the position indicated by the passing point position information to the line segment is less than the threshold. .

Note that the second passage point passage determination unit 305 reads the position information of all the passage points recorded in the storage unit 50 and passes the passage points when reading the passage point position information from the storage unit 50. Judging. However, the location information of the passing points recorded in the storage unit 50 in association with the two road IDs, the road ID included in the stop time information and the road ID included in the start time information, is read from the storage unit 50. It may be. Alternatively, the second passing point passage determination unit 305 does not use the road ID, but simply detects the detection position information (latitude x1, longitude y1) at the time of stop included in the information at the time of stop and the start time detection included in the information at the start time. The position information (latitude x2, longitude y2) is read, and the passing point associated with the position information in the vicinity (within a predetermined distance range from the detected position information at the time of stop and the detected position information at the time of start) is stored. It may be specified from the passing point recorded in the unit 50, and the position information of the passing point may be read from the storage unit 50.

Further, other processing methods may be used as a process for preventing a passage point passage determination omission when the traffic information processing apparatus 1 is stopped and started. For example, the second passing point passage determining unit 305 uses the road ID included in the stop time information and the passing point position information recorded in the storage unit 50 in association with the road ID included in the start time information. The position information of a passing point included in a predetermined rectangular range having the detected position information (latitude x1, longitude y1) at the stop and the detected position information (latitude x2, longitude y2) at the start of two of the four vertices. Determine if it exists. Then, when there is position information on the passing point included in the rectangular range, the second passing point passage determining unit 305 determines that the passing point corresponding to the position information included in the rectangular range has passed. May be.

The second passing point passage determination unit 305 also includes a plurality of points on each road recorded in the storage unit 50 in association with the road ID included in the stop time information and the road ID included in the start time information ( Read latitude and longitude information. Then, the second passage point passage determination unit 305 determines whether any point (latitude, longitude) on the road and the location information of the passage point on the road where the vehicle traveled before the operation stopped, When the distance from the position information of the travel point on the road that has traveled is less than the threshold value, it may be determined that the vehicle has passed the traffic point whose distance is less than the threshold value.

That is, if the process determines whether there is a passing point on the moving route between the detected position information at the time of stop and the detected position information at the time of start, the second passing point passage determination unit 305 determines what process It may be determined whether or not the passing point has been passed.
If it is not determined in step S302 that the passage point has been passed, it is determined that the passage determination cancellation process is to be terminated (step S309).

And when it determines with having passed the traffic point in the process of step S302, the 2nd traffic point passage determination part 305 passed the ID of the traffic point determined to have passed for the first time after the operation start, and the traffic point. Is output to the map matching unit 20. The second passage point passage determination unit 305 records the ID of the passage point determined to have passed and the passage time in the storage unit 50 in association with each other. The second passage point passage determination unit 305 records the ID of the passage point determined to have passed and the passage time in the storage unit 50 in association with each other even before the operation is stopped.

On the other hand, in the map matching unit 20, the passage point passing presence / absence determining unit 25 is the last detected before the operation stop (detected before the power is turned off) among the passage points already determined to have passed. Is recorded in the storage unit 50 (step S303). Accordingly, the passage point passage presence / absence determination unit 25 can determine that the passage point has been passed when the ID of the passage point is recorded in the storage unit 50. Note that the ID of the last detected passing point is recorded in the storage unit 50 as a result of the process of determining that the second passing point passage determining unit 305 has passed in step S202 described above. If no passage point is recorded, the passage point passage presence / absence determining unit 25 notifies the passage determination canceling unit of information indicating that, and determines that the passage determination canceling unit 28 ends the cancellation process of the passage determination (step). S309). The passage point passage presence / absence determination unit 25 outputs the ID of the passage point to the passage determination cancellation unit 28 when the storage point detected last before the operation is stopped is recorded in the storage unit 50.

Next, the road identification information coincidence determination unit 26 inputs a road ID (starting road identification information) from the operation start time information acquisition unit 24. Further, the road identification information coincidence determination unit 26 selects the road ID (of the road on which the last vehicle detected before the operation starts from the stop time information recorded in the storage unit 50 by the operation stop time information recording unit 23). Read the road identification information). Then, the road identification information coincidence determination unit 26 matches the road ID (start road identification information) input from the operation start time information acquisition unit 24 with the road ID (stop road identification information) read from the storage unit 50. It is determined whether or not to perform (step S304). Then, the road identification information coincidence determination unit 26 matches the road ID (start road identification information) input from the operation start time information acquisition unit 24 with the road ID (stop road identification information) read from the storage unit 50. If not, information indicating that the road IDs do not match is notified to the passage determination cancellation unit, and the passage determination cancellation unit 28 determines to end the passage determination cancellation process (step S309). The road identification information coincidence determining unit 26 matches the road ID (starting road identification information) input from the operation start time information acquiring unit 24 with the road ID (stopped road identification information) read from the storage unit 50. In this case, the start of processing is notified to the last passing point passage time acquisition unit 27.

Then, the last passage point passage time acquisition unit 27 stores the last passage time that is the passage time of the passage point that has been determined to have passed the last among the passage points that have already been determined to have passed before detection of the operation stop. Get more. Then, the final passing point passage time acquisition unit 27 outputs the acquired final passage time (T1) to the passage determination cancellation unit 28.

Here, the passage determination cancellation unit 28 has already input the current position (start detection position information) and the time (T3) when the operation start is detected from the operation start time information acquisition unit 24 by the above-described processing. Yes.
The passage determination canceling unit 28 has already input the ID (P1) of the last detected passing point from the passing point passage presence / absence determining unit 25 by the above-described processing.
The passage determination canceling unit 28 receives the final passage time (T1), which is the passage time of the passage point determined to have passed last before the operation stop, from the final passage point passage time acquisition unit 27.
Further, the passage determination canceling unit 28 inputs the ID (P2) of the passing point determined to have passed for the first time after the start of the operation and the passing time (T4) from the second passing point passage determining unit 305.

Then, the passage determination canceling unit 28 determines whether or not the ID (P1) of the last detected passing point before the operation stops and the ID (P2) of the passing point determined to have passed for the first time after the operation starts. Is determined (step S305). The passage determination cancellation unit 28 determines that the passage determination cancellation process is to be terminated if the compared IDs of the passage points do not match (step S309).

Further, the passage determination canceling unit 28, when the ID (P1) of the last detected point before stopping the operation and the ID (P2) of the passing point determined to have passed for the first time after starting the operation match. Next, the operation stop detection time (T2) is read from the stop time information recorded in the storage unit 50.
Then, the passage determination canceling unit 28 passes the passing point after the time from the last passage time (T1) to the time (T2) when the operation stop is detected and the time when the operation start is detected (T3). The time until the time (T4) when the determination unit first determines that the passage point has been passed is summed (step S306). Then, the passage determination cancellation unit 28 determines whether the total is less than a predetermined time (for example, 5 minutes) (step S307). If the total is less than the predetermined time, the second passage point determination unit 305 starts operation. It is determined to cancel the passage determination result for the passing point (P2) determined to have passed after detection (step S308).

Then, the passage determination cancellation unit 28 deletes the information (passage point ID and passage time) about the passage point (P2) that the second passage point passage determination unit 305 has determined to have passed after detecting the start of operation from the storage unit 50. . The passage determination canceling unit 28 also notifies the billing amount calculation unit 304 to stop the billing process when the billing process occurs when the passing point (P2) is passed. Thereby, the billing amount calculation unit 304 stops the billing process when the passing point (P2) is the confirmed point.
If it is not decided to cancel the passage determination result, as usual, if the passage point (P2) that the second passage point passage determination unit 305 has determined to have passed after detecting the start of operation is a fixed point, the billing process Is done.
Here, in the above-described example, the example in the case where the cancellation process is performed for the passage point passage determination performed in the second passage point passage determination unit 305 has been described. However, the passage performed in the first passage point passage determination unit 301 You may make it perform a cancellation process about the passage determination of a point.

Note that the above-described processing of the passage determination canceling unit 28 shows processing for canceling the second passage determination when it is determined that the same passage point has been passed twice within a predetermined time. When it is determined that the same passing point has been continuously passed twice or more within a predetermined time, it may be determined to cancel all the passage determination results after the second time.

The passage determination canceling unit 28 is a case where the road identification information at the time of stop coincides with the road identification information at the start, and the ID of the traffic point read by the traffic point passage presence / absence determination unit 25 and the second traffic point passing If the ID of the passing point determined that the determining unit 305 has passed matches, the second passing point passage determining unit 305 immediately detects the start of operation without performing the above-described steps S306 and S307. You may make it cancel the result determined with having passed later.

According to the processing of the passage determination canceling unit 28 described above, when the same passage point is passed a plurality of times, or when the same passage point is passed a plurality of times within a predetermined time, the first and subsequent passage judgments are canceled. Accounting processing can be performed. As a result, it is possible to prevent double charging due to erroneous position detection performed based on a signal from a GPS satellite.

Next, the details of the process for determining the travel route that has passed in the past in step S108 will be described.
FIG. 6 is a block diagram showing the configuration of the movement path specifying unit 22.
The movement route identification unit 22 includes an input unit 100, a communication unit 110, a map data storage unit 120, a road information identification unit 130, an estimated movement position calculation unit 140, a next route road information identification unit 150, an estimated movement route information generation unit 160, It includes an estimated movement route information storage unit 170, a movement route outside determination unit 180, a movement route output unit 190, a confirmed movement route storage unit 200, a billing request unit 210, and a control unit 1000.

FIG. 7 is a diagram for explaining road information stored in the map data storage unit.
The road information stored in the map data storage unit 120 is information on each road appearing on the map indicated by the map data, and the road ID of the road, the position (latitude, longitude) of the road in the real space, and the extension direction And the information of a connection road ID indicating other roads to be connected are stored. For example, roads appearing on a map indicated by map data are divided at positions such as branch points, start points, and end points of roads, and road IDs are assigned to the divided roads. For example, the road on the map as shown in FIG. 7 is divided into nine roads from the road ID1 to the road ID9 based on the start point, branch point, and connection point with other roads. The map data storage unit 120 is illustrated as being provided in the movement route specifying unit 22 for convenience of explanation, but may be provided outside the movement route specifying unit 22.

For the road as shown in FIG. 7, nine pieces of road information from the road of ID 1 to the road of ID 9 are recorded in the map data storage unit 120. In one road information, as the position of the road in the real space, there are a plurality of position information of the end points such as the start point and the end point of the road for one divided road indicated by the road ID, and a plurality of intermediate points. Location information may be stored.
For example, in the case of the road of ID1 in FIG. 7, the position information of the connection point connected to the road of ID2, the position information of the connection point connected to the road of ID3, the position information of the intermediate point of the road of ID1, etc. Stored in the road information of the road. Alternatively, the position information of each point at a predetermined interval between the end points such as the start point and the end point may be stored in the road information.

The extension direction stored in the road information is, for example, an angle formed with a certain reference direction. For example, if the reference direction is a direction of true north, the extension direction corresponding to the position of a point on a road included in the road information is a straight line connecting the position of another point on the same road adjacent to the point. This is the angle formed with the reference direction. Further, for example, in the present embodiment, the road information may include the position information of a plurality of points on the road and the extending direction indicated by the angle from the reference direction for each of the position information of the plurality of points. Good.

Further, since the road indicated by road ID1 is connected to the road indicated by road ID2 and the road indicated by road ID3, the road information including the road ID1 includes the connection road ID2 and the connection road as the connection road ID. Road ID3 is stored. Here, for example, these connection road IDs are registered in association with the position information of the end point on the side to which the road indicated by the connection road ID is connected, among the position information of the end points included in the road information. That is, for example, in the case of road information of road ID1, road ID2 is connected to the end point A of the road, and road ID3 is connected to the end point B of the road. Therefore, as road information of road ID1, road ID1, position information of end point A, and position information of end point B are stored. Further, road ID2 is associated with the position information of end point A and is associated with the position information of end point B. Road ID3 is stored. Various information in the road information may be stored in a format other than this.

FIG. 8 is a first diagram illustrating an estimated movement path information data table stored in the estimated movement path information storage unit.
The estimated travel route information storage unit 170 stores one or a plurality of estimated travel route information generated by the estimated travel route information generation unit 160 in the estimated travel route information data table. In the example of FIG. 8, immediately after the movement route specifying unit 22 starts processing, four pieces of road information estimated as roads on which the vehicle travels are specified from the road information recorded in the map data storage unit 120. It is an example at the time of recording in an estimated movement path | route information data table.

The example of FIG. 8 is an example in which four pieces of road information including ID = 1, 2, 4, 5 are specified immediately after the movement route specifying unit 22 starts processing, In each estimated movement route information, a non-movement route flag indicating whether or not it is determined that the route is not a movement route and road information are stored. In this embodiment, the out-of-movement-path flag is set to “0” in a situation where it is not determined that it is not a movement path, and is set to “1” in a situation where it is determined that it is not a movement path. The road information stored in the estimated travel route information is, for example, a road ID and an estimated likelihood. The estimated likelihood is a value indicating a degree (likelihood) that the road is estimated to be a road on which the vehicle including the traffic information processing apparatus 1 travels, and is a value calculated by the estimated movement route information generation unit 160. .
The estimated travel route information storage unit 170 is also illustrated as being provided in the travel route specifying unit 22 for convenience of explanation, but may be provided outside the travel route specifying unit 22.

FIG. 9 is a diagram illustrating a processing flow of the movement route specifying unit 22.
Next, details of the processing of the movement path specifying unit 22 will be described in order with reference to FIG.
First, the control unit 1000 outputs a road information specifying process start request signal to the road information specifying unit 130 based on an external instruction or the like. Then, the road information specific | specification part 130 starts a road information specific process (step S1010). Then, the road information specifying unit 130 of the movement route specifying unit 22 inputs a sensing position from the position information calculating unit 15 in the input unit 100, and starts moving within the error range of the sensing position using the sensing position. Initial road information is specified (step S1020).

FIG. 10 is a first diagram illustrating an outline of processing of the road information specifying unit 130.
The processing in step S1020 will be described in more detail. The road information specifying unit 130 reads the distance of the error range recorded in advance from a memory or the like. The road information specifying unit 130 reads one road information from the map data storage unit 120, calculates the distance between the input sensing position and the position information included in the road information read from the map data storage unit 120, It is determined whether the distance is less than the distance indicated by the error range. Then, the road information specifying unit 130 specifies road information whose distance between the sensing position and the position information is less than the distance indicated by the error range as a candidate for an initial road that may be on the moving route. To do. Then, the road information specifying unit 130 similarly determines whether there is a road within the error range using the road information about each road stored in the map data storage unit 120, and indicates the road within the error range. The road information is estimated and specified as road information indicating a possible road candidate on the moving route.

FIG. 10 shows an example in which the sensing position of the vehicle is near the connection point between the road with the road ID1 and the road with the road ID2. In this case, the distance between the position of a point (such as an end point) on the road included in each of the four road information including each road ID of road ID1, road ID2, road ID4, and road ID5 and the current position is within an error range. Suppose there is. Then, the four pieces of road information including the road IDs of the road ID1, road ID2, road ID4, and road ID5 are estimated and specified as road information indicating possible road candidates on the movement route.
The road information specifying unit 130 reads the four specified road information including the road IDs of the road ID 1, the road ID 2, the road ID 4, and the road ID 5 from the map data storage unit 120 and outputs the read road information to the estimated movement position calculation unit 140. To do. Further, the road information specifying unit 130 outputs the four specified road information to the estimated moving route information generating unit 160 as road information at the beginning of movement.

When the estimated movement route information generation unit 160 inputs road information at the beginning of movement, the estimated movement route information generation unit 160 determines whether the estimated movement route information is already recorded in the estimated movement route information data table of the estimated movement route information storage unit 170. Here, in the initial state, the estimated travel route information is not recorded in the estimated travel route information data table of the estimated travel route information storage unit 170. The estimated movement route information generation unit 160 reads the road ID from each road information at the beginning of movement specified by the road information specification unit 130, and generates estimated movement route information separately including the road ID (step S1030). That is, the estimated movement route information generation unit 160 includes the estimated movement route information 1 including the road ID1, the estimated movement route information 2 including the road ID2, the estimated movement route information 3 including the road ID4, and the estimated movement including the road ID5. Route information 4 is generated. Then, the estimated movement route information generation unit 160 registers the information of the estimated movement route information 1 to 4 in the estimated movement route information data table.

At this time, the estimated travel route information generation unit 160 associates, for the estimated travel route information 1, the out-of-travel route flag “0” indicating a situation that is not determined to be a travel route and the road ID 1 as the road information. And recorded in the estimated travel route information data table in the estimated travel route information storage unit 170.
Further, the estimated travel route information generation unit 160 estimates the estimated travel route information 2 by associating the travel route outside flag “0” indicating a situation that is not determined to be a travel route with the road ID 2 as the road information. The estimated movement route information data table in the movement route information storage unit 170 is recorded.
Further, the estimated travel route information generation unit 160 estimates the estimated travel route information 3 by associating the travel route outside flag “0” indicating a situation that is not determined to be a travel route with the road ID 4 as the road information. The estimated movement route information data table in the movement route information storage unit 170 is recorded.
Further, the estimated travel route information generation unit 160 estimates the estimated travel route information 4 by associating the out-of-travel route flag “0” indicating a situation that is not determined to be a travel route with the road ID 5 as the road information. The estimated movement route information data table in the movement route information storage unit 170 is recorded.
Thereby, the estimated movement route information generation part 160 produces | generates an estimated movement route information data table as shown in FIG.

FIG. 11 is a second diagram showing an outline of processing of the road information specifying unit 130.
On the other hand, when the estimated movement position calculation unit 140 receives the road information at the beginning of movement specified by the road information specification unit 130, the estimated movement position calculation unit 140 selects the end point of the position information included in the road information from the end point of the vehicle in the real space. The position information of one end point close to the current position is specified. For example, position information of one end point close to the current position is read from four pieces of road information including road ID1, road ID2, road ID4, and road ID5. Then, the travel distance is sequentially calculated using the vehicle speed signal, acceleration, each speed, latitude and longitude, etc., input from the position positioning unit 10 over time. The estimated movement position calculation unit 140 sequentially calculates the estimated movement position (see FIG. 11A) corresponding to the movement distance from each one of the end points specified in the four specified road information (step S1040), The road information specified by the road information specifying unit 130 and the estimated movement position calculated repeatedly over time for each of the specified road information are output to the next route road information specifying unit 150.

The next route road information specifying unit 150 sequentially inputs the road information specified by the road information specifying unit 130 and the estimated moving position for each of the specified road information from the estimated moving position calculating unit 140. Then, the next route road information specifying unit 150 determines the distance between the position information of the other end point different from each one of the end points specified in the four specified road information and the estimated movement position, by road ID1, road ID2, Each road information indicated by the road ID 4 and the road ID 5 is repeatedly calculated, and it is determined for each road information whether it is within a predetermined distance (step S1050). Then, the road information that is within the predetermined distance earliest is specified (step S1060). As a result, when it is estimated that each of the roads indicated by the road information specified by the road information specifying unit 130 has moved according to the movement distance indicated by the estimated movement position, Identify the road that reaches the connection point.

Then, the next route road information specifying unit 150 includes the road information that specifies that the current position of the vehicle is closest to the position of the other end point in each road information indicated by the road ID1, road ID2, road ID4, and road ID5. The road information of the connecting road connected to the other end point is specified as the road information (see FIG. 11B) indicating the next route candidate (step S1070). For example, the next route road information specifying unit 150 includes the road information of the road specified that the current position of the vehicle is closest to the position of the other end of each road indicated by the road ID1, road ID2, road ID4, and road ID5. The connection road ID held in association with the position information of the other end point is detected. Then, the next route road information specifying unit 150 reads the road information including the road ID having the same ID as the connection road ID from the map data storage unit 120 and uses the road information as the road information indicating the candidate road for the next route. Identify. In the example of FIG. 11B, the road information with the road ID 4 and the road information with the road ID 5 are specified as road information that is a candidate for the next route. Then, the next route road information specifying unit 150 is road information that is a candidate for the current travel route specified by the road information specifying unit 130 and a road that is a candidate for the next route specified by the next route road information specifying unit 150. Information to the estimated movement route information generation unit 160.

The estimated travel route information generation unit 160 is road information that is a candidate for the current travel route specified by the road information specification unit 130 and road information that is a candidate for the next route specified by the next route road information specification unit 150. Is input from the next route road information specifying unit 150, the estimated likelihood of each road indicated by the road information that is a candidate for the current travel route is calculated. The estimated likelihood is an index value indicating the degree of likelihood (likelihood) that the vehicle is traveling on the road indicated by the road information that is a candidate for the current travel route.

As a specific calculation method, for example, the estimated travel route information generation unit 160 obtains vehicle position information P1 at each processing timing while traveling on a road that is a candidate for the current travel route from the position measurement unit 10, and First, a travel distance L1 and a traveling direction D1 traveled on the road are calculated.
In addition, the estimated movement route information generation unit 160 reads each position information P2, included in the road information that is a candidate for the current movement route, the extension distance L2 between the end points of the road, and the extension direction D2. Then, the estimated movement route information generation unit 160 uses the estimated likelihood calculation formula, the difference between the position information P1 at each processing timing and the position information P2 closest to the position indicated by P1, the difference between the movement distance L1 and the extension distance L2. The difference between the angle indicated by the traveling direction D1 (the angle from the reference direction such as true north) and the angle indicated by the extending direction D2 (the angle from the reference direction such as true north) is calculated, and a value obtained by weighting them is calculated. The sum is calculated as the estimated likelihood. The estimation likelihood calculation method may be any method as long as it can calculate an index value indicating the degree of possibility that the vehicle is traveling on a road that is a candidate for the current travel route. Good. Then, the estimated movement route information generation unit 160 associates the estimated likelihood calculated for the road information that is a candidate for the current movement route with the road ID of the road information, and stores it in the estimated movement route information data table shown in FIG. Recording is performed (step S1080). Then, the calculation of the estimated likelihood and the recording in the estimated travel route information data table are performed for the road information that is a candidate for all current travel routes.

After the process in step S1060 described above, the next route road information specifying unit 150 sets the road information specified as the next route candidate as the current travel route candidate, and indicates the current travel route candidate. Information is output to estimated movement position calculation section 140. Then, the estimated movement position calculation unit 140 calculates the estimated movement position in the same manner as described above using the road information that is a candidate for the current movement route input from the next route road information specifying unit 150. Further, based on the estimated movement position, the next route road information specifying unit 150 specifies specifying information that is a candidate for the next route. The estimated movement position calculation unit 140 and the next route road information specifying unit 150 repeat the same processing at intervals of predetermined timings (T1, T2,...), And the next route road information specifying unit 150 sets the predetermined intervals. Thus, the road information that is a candidate for the current travel route and the road information that is a candidate for the next route are output to the estimated travel route information generation unit 160.

The estimated travel route information generation unit 160 inputs road information that is a candidate for the current travel route and road information that is a candidate for the next route at predetermined intervals from the next route road information specifying unit 150. For each input, the estimated travel route information is updated or generated (step S1090). More specifically, the estimated travel route information generation unit 160 determines whether the estimated travel route information is already recorded in the estimated travel route information data table of the estimated travel route information storage unit 170. Here, the estimated movement route information including the road ID of the road information at the beginning of the movement is already recorded in the estimated movement route information data table by the above-described processing. Then, the estimated travel route information generation unit 160 connects the road information identified as the current travel route candidate and the connection road ID associated with the position information of the end point included in the road information identified as the next route candidate. The road information holding the same road ID is specified. The estimated movement route information in which the road ID included in the road information and the road ID included in the specified road information are associated with the next route candidate is separately obtained for all the road information specified as the next route candidate. To generate.

In other words, using the examples of FIGS. 10 and 11, the road information specified as the current travel route candidate is road information including road ID 1, road ID 2, road ID 4, and road ID 5. The road information identified as a candidate for the next route is road ID 4 and road ID 5. Then, the estimated movement route information generation unit 160 reads the connection road ID associated with the position information of the end point from the road information of the road ID 4 and the road ID 5 identified as the next route candidate. The connection road ID includes the connection road ID2. Then, the estimated movement route information generation unit 160 identifies road information having the same road ID as the read connection road ID from road information including road ID1, road ID2, road ID4, and road ID5.
That is, road information including road ID 2 is specified.

Then, the estimated movement route information generation unit 160 copies the estimated movement route information (estimated movement route information 2 in FIG. 8) including the connection road ID2 as the road ID of the road information specified last time (at timing T1), In the copied estimated travel route information, new estimated travel route information 2-2 is generated in which the next route candidate (at timing T2) and the road ID 4 of the identified road information are stored in association with the road ID2. Similarly, the estimated travel route information generation unit 160 copies the estimated travel route information (estimated travel route information 2 in FIG. 8) including the connected road ID2 as the road ID of the road information specified last time (at timing T1). In the copied estimated travel route information, new estimated travel route information 2-3 is generated in which the next candidate (at timing T2) and the road ID 5 of the identified road information are stored in association with the road ID2.

Further, the estimated movement route information generation unit 160 reads the road ID for each of the estimated movement route information 1 to 4 already recorded in the estimated movement route information storage unit 170, and uses the road ID as the estimated movement route information. In association with the same road ID. That is, the estimated travel route information 1 is updated by associating the road ID 1 that is information of the road identified as the estimated travel route at timing T1 and the road ID 1 that is information of the road identified as the estimated travel route at timing T2. Similarly, the estimated travel route information 2 is updated by associating the road ID 2 that is information on the road identified as the estimated travel route at timing T1 with the road ID 2 that is information on the road identified at timing T2. . Similarly, the estimated travel route information 3 is updated by associating the road ID 4 that is the information of the road identified as the estimated travel route at the timing T1 and the road ID 4 that is the information of the road identified as the estimated travel route at the timing T2. . Similarly, the estimated travel route information 4 is updated by associating the road ID 5 that is information on the road identified as the estimated travel route at timing T1 with the road ID 5 that is information on the road identified at timing T2. .

FIG. 12 is a second diagram showing an estimated movement path information data table stored in the estimated movement path information storage unit.
As a result of the processing of the estimated travel route information generation unit 160 described above, the estimated travel route information data table is converted into the estimated travel route information 1, the estimated travel route information 2, the estimated travel route information 2-2, the estimated travel, as shown in FIG. Route information 2-3, estimated travel route information 3, and estimated travel route information 4 are stored. As shown in FIG. 12, at the end stage of the process of the estimated movement route information generation unit 160 described above, each estimated movement route information in the estimated movement route information data table is specified at the beginning of movement (timing T1). The road ID of the road information (road information 1) and its estimated likelihood are recorded, and the road identified by the next route road information identifying unit 150 as a candidate for the next route at timing T2 in association with the road ID. The road ID of the information (road information 2) is recorded. However, the estimated likelihood associated with each road ID indicated by the road information 2 is not yet registered at the time of this processing.

Then, the estimated travel route information generation unit 160 next selects the road information to be a candidate for the current travel route specified by the road information specification unit 130 and the next route candidate specified by the next route road information specification unit 150 next time. When the next road information is input from the next route road information specifying unit 150, the same process as the above-described estimation likelihood calculation method is performed. Then, the estimated movement route information generation unit 160 calculates an estimated likelihood for the road of each road ID indicated by the road information 2, and corresponds to the estimated likelihood calculated for each road information that is a candidate for the current movement route. In association with the road ID of the road information to be recorded in the estimated movement route information data table. Thereby, the estimated likelihood is recorded in association with each road ID recorded as the road information 2 of each estimated movement route information in FIG.

Next, the out-of-travel-route determination unit 180 recently identified the road ID of the road that is considered to be unlikely to be a travel route from the estimated travel route information recorded in the estimated travel route information storage unit 170. A process of excluding the estimated movement route information recorded as the road ID of the road information from the candidates is performed (step S1100).
In this process, for example, when a request for specifying a travel route in which a road ID is stored is input from the first passage point passage determination unit 301 of the traffic information processing apparatus 1, the request is read from the request for specifying the travel route. The estimated travel route information that records a road ID other than the road ID as the road ID of the last specified road information is excluded from the candidates.
Alternatively, for example, the estimated movement route information in which the estimated likelihood equal to or less than the threshold is recorded among the estimated likelihoods recorded in the estimated movement route information in association with the road ID of the road information specified last. Are excluded from the candidates.

FIG. 13 is a diagram showing an outline of the process of the determination unit outside the movement route.
FIG. 13 shows the estimated movement route information shown in FIG. 12 in a tree diagram. Each estimated movement route information stores road information specified at each of timings T1 and T2. In such a state, the out-of-movement-path determination unit 180 records an estimated likelihood equal to or less than a threshold (for example, estimated likelihood 0.3) in association with the latest (timing T2) road information based on the estimated likelihood. In this example, the estimated travel route information 1, the estimated travel route information 3, and the estimated travel route information 4 are excluded from candidates.

FIG. 14 is a third diagram showing an estimated movement route information data table stored in the estimated movement route information storage unit 170.
The out-of-movement-path determination unit 180 identifies the road ID of the road that is considered to be unlikely to be a movement route from the estimated movement route information recorded in the estimated movement route information storage unit 170 last (timing T2). When the estimated movement route information recorded as the road ID of the road information is excluded, as shown in FIG. 14, the movement route outside flag stored in the estimated movement route information determined to be excluded is changed from “0” to “ Rewrite to “1”. Then, the determination unit 180 outside the travel route outputs a travel route confirmation request to the travel route output unit 190.

Next, when the travel route output unit 190 receives a travel route confirmation request from the travel route outside determination unit 180, the travel route information including the “0” in the travel route outside flag recorded in the estimated travel route information storage unit 170. The road ID to be determined as the travel route is specified from the road IDs indicating the roads estimated as the past travel route using the road ID included in (step S1110). Specifically, for example, the travel route output unit 190, for example, the road recorded first in all the estimated travel route information including “0” in the travel route outside flag recorded in the estimated travel route information storage unit 170. The road IDs are compared in order from the ID, and a common road ID is extracted continuously. Then, the travel route output unit 190 identifies the extracted roads indicated by the common road IDs continuously from the first road ID as the confirmed travel route, and indicates the confirmed travel route “continuous from the first road ID. And the common road ID ”is recorded in the confirmed movement route storage unit 200.

FIG. 15 is a first diagram illustrating an outline of processing of the movement route output unit.
In this figure, each estimated movement route information including road information specified at each timing T1, T2, T3, and T4 is shown in a tree diagram. Also, an example is shown in which, based on the estimated travel route information, a road indicated by a road ID that is continuously common from the first road ID identified at timing T1 is identified as a confirmed travel route. The example of FIG. 15 is an example in the case where there are three pieces of estimated movement route information including “0” as a non-movement route flag recorded in the estimated movement route information storage unit 170. The travel route output unit 190 uses the three estimated travel route information to determine the road ID 2 identified at the timing T1 and the road ID 4 identified at the timing T2 as a common road ID continuously from the first road ID. The example recorded in the movement path | route storage part 200 is shown.

The map matching unit 20 plots and displays the current position on a map displayed on a display unit such as a monitor in parallel with the movement route specifying unit 22 performing steps S1010 to S1110 described above. Map matching processing is performed. Then, the control unit 1000 of the movement route specifying unit 22 is based on inputs such as a power-off, a processing primary stop request signal included in a radio signal received from an external device when entering a parking lot, and a billing request signal from the outside. Whether or not to end is determined (step S1130), and if not ended, the processing from step S1040 is repeated. As a result, the new estimated movement route information is recorded in the estimated movement route information data table of the estimated movement route information storage unit 170, the estimated movement route information is updated, or the estimated movement route information is excluded from the candidates. . The travel route output unit 190 sequentially records the road ID indicating the confirmed travel route in the confirmed travel route storage unit 200 after step S1110 by repeating the process. Then, when the charge request unit 210 of the travel route specifying unit 22 inputs from the control unit 1000 that it is determined that the travel point is passed, the charge that stores information such as the road ID recorded in the confirmed travel route storage unit 200 is stored. The amount calculation request is output to the charge amount calculation unit 304 of the application unit 30. Thereby, the charge amount calculation unit 304 calculates the charge amount.

The traffic information processing apparatus described above has a computer system inside. Each process described above is stored in a computer-readable recording medium in the form of a program, and the above process is performed by the computer reading and executing the program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
