Description

  The present invention relates to a system for providing traffic regulation information for vehicles on a road. In particular, when searching for a route from the departure point to the destination, if the road or intersection you are about to pass or enter is subject to traffic restrictions, pass / fail information is provided to determine whether or not it is possible to pass or enter. Information provision system.

  In recent years, in-vehicle navigation devices are mainly used when performing a route search from a departure place to a destination. Map information is stored on a DVD or hard disk, and a map around the current position is displayed on the display screen from the DVD or hard disk according to the current position detected using a GPS (Global Positioning System) satellite, and a route to the destination is searched. It is possible to guide and guide. When conducting a route search, it is necessary to take into consideration traffic regulations such as one-way roads and intersections and entry prohibition. Regulatory information is becoming more and more important as map data is fresh. If the regulatory information is not accurate, it may lead to an unexpected accident. If an accident is caused by incorrect guidance, it may develop into a liability problem.

  FIG. 2 is a block diagram showing an outline of such a navigation system. An input unit 240 for giving various instructions, a GPS unit 230 for receiving a radio wave from a satellite to detect a current position, and a DVD storing map data. A map data acquisition unit 220 that reads map data from a storage medium such as a hard disk, a control device 250 that controls the whole, a display unit 210 that displays processing results, and a route search unit that searches for a guidance route from the departure point to the destination 270, a traffic regulation process that reads map data from the map data acquisition unit 220, determines whether there is traffic regulation information corresponding to the vehicle type input from the input unit 240, and acquires the information if there is information 280, and a time information acquisition unit 290 that specifies time and date information based on time information received from GPS. There.

  In the navigation system having such a configuration, when the power is turned on, the GPS unit 230 acquires the radio wave from the GPS satellite, starts detecting the latitude and longitude of the current position where the device itself is located, and controls the detection result. Input to device 250.

  On the other hand, the control device 250 performs initialization processing after power-on, and then uses the latitude / longitude information of the current position input from the GPS unit 230 to perform a predetermined process centered on the current position in the map data acquisition unit 220. The map data of the range is read, and a map that visualizes the map data is displayed on the display unit 210.

  When performing a route search, when the destination search menu is selected from the command menu displayed at the top of the display unit 210, the destination is determined by selecting the latitude and longitude of the destination, the address name, and the like. . When the destination is determined, the map data acquired by the map data acquisition unit 220 for the optimum route to the position, the restriction information determined by the traffic restriction processing unit 280, and the time / month / sunday information acquired by the time information acquisition unit 290 are used. The route search unit 270 comprehensively determines and creates a plurality of route candidate information. When a plurality of route candidate information is displayed on the display unit 210, the user selects one of them to determine the guide route.

  When performing the route search as described above, the handling of the regulation information and the accuracy of the information are important. The regulation information for major roads such as highways and national roads is often simple in terms of content, but the regulation information for fine roads may have complicated regulations that change the regulation contents depending on time or day of the week.

  So far, Patent Document 1 has proposed a method that can take a fine response to traffic regulation information whose regulation contents are changed by time or day of the week.

JP 2002-323330 A

  However, in the above-described conventional navigation apparatus, there is a navigation apparatus that cannot accurately represent regulations in the real world due to the specification restriction of the car navigation data format. In such a case, the regulation information as in the real world is not stored as map data, and the regulation information is rounded and stored so as to fit the specification of the car navigation data format.

  It seems that the places where complicated regulations are attached are not major roads such as expressways, national roads, prefectural roads, etc., but because they are often narrow roads at a fine level, they are unlikely to be subject to route search and are unlikely to be a problem It seems to have done.

  This problem can be solved by changing the format of the car navigation data to a format that can express any real-world regulatory information, but changing the format of the car navigation data means that the car navigation data creation side or hardware Side and the in-vehicle software side have a fairly wide range of influences and cannot be easily changed.

  Further, in the method proposed in Patent Document 1, a certain degree of response can be taken by taking a logical product or logical sum for traffic regulation information whose regulation contents are changed by time or day of the week. This method cannot be used when there is a regulation that excludes.

  For example, there is a period in which traffic is not allowed during certain days of the week, such as “cannot pass from 8:00 to 20:00 on Saturdays and Sundays, but excludes from August 1 to October 31”, but the regulation is not applicable. This is the case.

  An object of the present invention is to solve these problems. Even if data that does not correctly represent real-world regulations is retained due to a problem in the format specification limitation of the car navigation data format, the real-world A pass / fail information providing system that allows a terminal to obtain pass / fail information in consideration of real world regulations by inquiring to the pass / fail information providing system for any complicated regulation expression. It is to provide.

In order to achieve the above object, the access permission / prohibition information providing system of the present invention has a restriction information database having both an application part and an application exclusion part of restriction data corresponding to latitude / longitude information, and includes route information from a terminal device. Upon receiving the transmission of route information from the receiving means and the terminal device that receives the transmission, the restriction data corresponding to the latitude and longitude in the route information is read from the restriction information database and the route search result is requested and the route search result is requested. It is characterized by transmitting / receiving means for transmitting to the original terminal device.

  In addition, the present invention is characterized by a traffic regulation acquisition method for extracting the regulation of the actual day, month, day, and day of the week according to the vehicle type by having both the application part and the application exclusion part in the restriction data.

According to the passability information providing system of the present invention, there are the following effects.
(1) Even if there is an incorrect restriction data held on the mobile terminal side, it is possible to determine whether or not traffic is allowed in the real world by making an inquiry to the passability information providing system, and to prevent erroneous guidance. .
(2) Due to restrictions on the current car navigation data format, even if the actual regulations cannot be expressed, it is not necessary to change the car navigation format at all. It is possible to determine whether or not the street can pass and prevent erroneous guidance.
(3) Since all restriction data is correctly held on the passability information providing system side, the terminal side does not need to hold the restriction data at all in an extreme case, and the map data held on the DVD or hard disk The capacity can be reduced.
(4) Having the information on the excluded section as the restriction data makes it possible to reduce the capacity of the restriction data that is held.

Latitude / longitude 310 represents the only position where the road can be specified in the case of a road having restriction information, and represents the position of the intersection in the case of an intersection. The vehicle type 320 has a distinction between general vehicles, buses, trucks, emergency vehicles, etc., and the Monday-Sunday division 330 is data for identifying whether to specify the day of the month or the day of the week. FIG. The month and day are set because it is the month and day regulation data. The exclusion period ID array 370 is information for excluding the period in which the restriction is not applied from the month and day restriction period shown in FIG. 3A. FIG. 3C is the exclusion month day period data or FIG. This is ID information indicating data, and is associated with a number stored in the exclusion period ID array 370. If exclusion period information does not exist, 0 is stored.

  FIG. 3B shows day-of-week restriction data, which includes data of longitude / latitude 310, vehicle type 320, Monday-Sunday classification 330, day-of-week information 380, time zone 360, and exclusion period ID array 370. Since FIG. 3 (b) is day restriction data, the day of the week is set. Excluded period ID array 370 is information for excluding a period in which no restriction is applied from the day of the week restricted period shown in FIG. 3B. FIG. 3C is an excluded month / day period data or FIG. 3D is an excluded day of the week period data. ID information indicating the relationship between the numbers stored in the exclusion period ID array 370. If exclusion period information does not exist, 0 is stored.

  FIG. 3 (d) shows the excluded day period data, which is composed of data of an excluded period ID 390, Monday-Sunday division 330, excluded day information 380, and excluded time zone 360.

Here, for example, restriction data at a certain point is shown in FIG.
A general vehicle represented by a vehicle type 411 has regulation information for the day of the week represented by a Monday-Sunday division 412 at a latitude of 48 degrees 10 minutes 20 seconds north and a longitude of 16 degrees 23 minutes 56 seconds. The day and time indicate that there is a restriction of 6:00 to 20:00 on Tuesday represented by the day information 413 and the time information 414. Further, since the exclusion period ID 415 is 1, it has exclusion period information. The exclusion period is associated with the day-of-week restriction data with ID = 1 represented by the exclusion period ID 420, has the exclusion period information of the month and day represented by the Monday-Sunday division 421, and includes the exclusion start month 422 and the exclusion end month. From day 423 to April 1 to September 30 represents an exclusion period. Since the exclusion time 423 is NULL, there is no time to exclude.

  FIG. 5 is a data configuration diagram of data transmitted from the mobile terminal 170 to the passability information providing system. This is also the same format for data transmitted from the passability information providing system to the mobile terminal 170. It consists of a sender ID 500, the number of information 501, and inquiry information 502. The inquiry information includes a road intersection flag 503, a latitude / longitude 504, and a determination result flag 505. Source ID 500 is an ID that identifies a mobile terminal. The number of information 501 represents the number of inquiry information. Inquiry information 502 stores information on roads and intersections to be inquired from the mobile terminal. A road intersection flag 503 is a flag for identifying whether the information is a road or an intersection. In the case of a road, the latitude / longitude 504 is the latitude / longitude of a place where the road can be uniquely identified, and in the case of an intersection, the latitude / longitude of the position of the intersection. In the case of an intersection, whether to pass or not may change depending on the approaching / leaving road, so it is necessary to make an inquiry in a form sandwiched between the information on the approaching road and the leaving road as the passage route. The determination result flag 505 represents a result determined by the passability information providing system. When inquiring from the mobile terminal 170, an initial value is stored.

  Hereinafter, the operation of the passability information providing system configured as described above will be described.

  FIG. 6 is a flowchart showing an outline of the passability information determination process of the passability information providing apparatus 100. First, the passage permission / prohibition information providing system 100 acquires route information sent from the mobile terminal 170 that is inquired about passage permission / inhibition (step 600). Since the route information includes the latitude and longitude information of the nodes and links, the restriction information corresponding to the latitude and longitude is acquired from the restriction information DB 150 (step 601). Since the vehicle type information is sent from the mobile terminal 170 that wants to inquire whether or not traffic is permitted, it is determined whether the vehicle type information and the vehicle type information included in the regulation information match (step 602). If they do not match, the restriction information is not relevant, so the next restriction information is processed. If the vehicle type matches, the current month, day, time, and day information is sent from the mobile terminal 170 that wants to inquire whether or not the vehicle can pass. Whether or not (step 603). If it is out of the range, the regulation information is not relevant, so the next regulation information is processed.

  If it is within the range, it is set to the ON state indicating that the passage prohibition flag cannot pass (step 604).

  It is determined whether or not steps 602, 603, and 604 have been processed for the number of pieces of restriction information (step 605). If the number of pieces of restriction information has not been processed, steps 602, 603, and 604 are repeated.

  When processing is performed for the number of pieces of restriction information, exclusion period information corresponding to the exclusion period ID included in the restriction information is acquired from the restriction information DB 150 (step 606). It is determined whether the current date and time information is within the exclusion period information range (step 607). If it is within the range of the exclusion period information, it is in a passable state, so the passability flag is set to an OFF state indicating that the passable state is present (step 608). If it is not within the range of the exclusion period information, it does not correspond to the exclusion period, so the next exclusion period information is processed.

  It is determined whether or not steps 607, 608 and 609 have been processed for the number of exclusion period information items (step 610). If processing is not performed for the number of exclusion period information, steps 607, 608, and 609 are repeated.

  The information about the nodes in which the incompatibility flag for the processed node / link is in the ON state indicating the inability to pass is saved (step 610).

  It is determined whether or not processing has been performed for the number of route information (step 611). If not, the processing after step 601 is continued. When the processing is completed for the number of pieces of route information, the pass / fail judgment result for all the nodes and links is obtained.

  Finally, the passability determination result obtained by the passability determination result obtained by the passability determination processing unit 110 of the passability information providing system 100 is transmitted to the mobile terminal 170 by the result of the passability determination result transmission unit 120. It becomes possible to know which nodes and links are inaccessible.

  The present invention can be used for a passability information providing system that communicates with an in-vehicle navigation system such as an automobile or a motorcycle. The present invention can be used for a passability information providing system that communicates with a navigation system in a mobile terminal such as a mobile phone. It can be used for a pass / fail information providing system that is accessed from a personal computer via the Internet.
