The intersection information with traffic lights 2 is stored in the intersection information storage section 2 with traffic lights. The intersection information with a traffic signal is information for identifying an intersection where a traffic signal is installed on a map, and for example, a combination of a node as map information and information regarding the presence or absence of a traffic signal as road information can be used.

The travel history data storage unit 3 stores travel history data when the vehicle actually travels. As travel history data, probe information can be mentioned, for example. The probe information includes at least coordinate information and ID information for specifying the probe car. Any vehicle having a position detection function such as GPS can identify these pieces of information. Furthermore, time information, speed information, heading information, altitude information, accelerator opening, engine speed, longitudinal acceleration, yaw rate, stop lamp, ABS warning lamp, fuel consumption, remaining power capacity, rudder angle (steering wheel rotation angle information) ), Shift lever information and the like.
The target intersection selection unit 4 refers to the traffic signal-equipped intersection information storage unit 2 and selects a traffic signal-equipped intersection as a target intersection for specifying the stop ratio. The selected intersection may be an intersection with a traffic light, but may be an intersection with a traffic light that exists on a main road, for example. In the navigation system, the guide route is mainly selected because it is a main road. The selected target intersection information is stored in the target intersection storage unit 5.

  The passing intersection extracting unit 6 refers to the trafficked intersection information storage unit 2 and extracts a trafficked intersection that has passed immediately before reaching the target intersection as a passing intersection according to a predetermined rule. As a predetermined rule, for example, when an intersection with a traffic light that has passed immediately before reaching the target intersection is within a certain distance from the target intersection, the intersection with a traffic light can be extracted as a passing intersection. Further, as another rule, the target intersection and the intersection with a traffic signal that passed immediately before reaching the target intersection are connected to the intersection with a traffic signal that is connected along the road without turning at a node existing between the two intersections. It is good to do. Furthermore, as a passing intersection, it may be a rule to exclude a specific type of traffic signal such as a push button traffic signal. Other specific traffic signal types include blinking traffic lights, vehicle sensitive traffic lights, and the like.

The number of passing intersections to be extracted may be one, or two or more passing intersections may be set. For example, a first intersection with a traffic signal that passes immediately before reaching the target intersection and a second intersection with a traffic signal that passes immediately before reaching the first intersection with a traffic light are set as a passing intersection. it can.
If the passing intersection is extracted according to the predetermined rule, the stop ratio at the target intersection can be specified more accurately.

  The route sorting unit 7 includes a travel history of traveling the extracted passing intersection and the target intersection stored in the target intersection storage unit 5 among the travel history data stored in the travel history data storage unit 3. Sort travel history data by route. Here, the travel history data sorted for each route has the same travel route from the passing intersection to the target intersection, and at least the link directly connected to the passing intersection (hereinafter also referred to as the inflow link) and the target intersection. It is preferable that the directly connected links (hereinafter also referred to as outflow links) are sorted so as to be the same. For example, when the passing intersection and the target intersection are both four-way differences, the route sorting unit 7 has nine routes in consideration of three inflow links connected to the passing intersection and three outflow links connected to the target intersection. Will be sorted. Based on the travel history data sorted for each route in this way, if the stop ratio at the target intersection, which will be described later, is specified, the linkage of the signal switching timing between the passing intersection and the target intersection and the difference between the inflow / outflow links The stop ratio is taken into account.

When sorting the travel history data for each route, the route sorting unit 7 may sort the travel history data excluding the travel history data that is extremely slow and the travel history data that significantly exceeds the speed limit set for the route. good.
The travel history data sorted for each route is stored in the first route storage unit 81, the second route storage unit 82,..., The nth route storage unit 8n in the route storage unit 8 in association with the route. (See FIG. 8).
The stop ratio specifying unit 9 specifies the ratio at which the probe car stops at the target intersection as the stop ratio for each classified route. The stop rate specifying unit 9 may specify the stop rate when the number of travel history data stored in each route storage unit in the route sorting unit 7 is equal to or greater than a predetermined threshold. The specified stop ratio is stored in the stop ratio storage unit 10.

The detailed configuration of the stop ratio specifying unit 9 will be described with reference to FIG.
The stop ratio specifying unit 9 includes a first all data counter 91, a first stop data counter 92 for specifying a stop ratio for the travel history data stored in the first route storing unit 81 in the route storing unit 8. A first computing unit 93 and a first specifying unit 94 are provided.

  The first total data counter 91 counts the total number of travel history data stored in the first route storage unit 81, and the first stop data counter 92 stores the travel history stored in the first route storage unit 81. Count the number of stop data among the data. Here, the stop data refers to the travel history data stopped at the target intersection. For example, the stop data can be used as the stop data when the vehicle speed at the target intersection in the travel history data is zero. Here, the determination of the vehicle speed may be performed in the section between the passing intersection and the target intersection in addition to being performed at the target intersection. Moreover, it is good also as carrying out stop data on the driving | running | working history data whose vehicle speed is zero in the area from the predetermined distance before the target intersection (for example, 30 m) to the target intersection.

The first calculator 93 calculates the ratio of the number counted by the first stop data counter 92 to the number counted by the first all data counter 91.
The first specifying unit 94 specifies the calculated ratio as the first stop ratio. The identified stop ratio is stored in the stop ratio storage unit 10 in association with the route.

In step 3, the traffic lighted intersection information storage unit 2 and the target intersection storage unit 5 are referred to, and the traffic lighted intersection that has passed immediately before reaching the target intersection selected in step 1 is extracted as a passing intersection.
Next, among the travel history data stored in the travel history data storage unit 3, the travel history data passing through the extracted passing intersection and the target intersection stored in the target intersection storage unit 5 is classified for each route. Save (step 5).
In step 7, the stop ratio at the target intersection is specified and stored for the travel history data stored for each route.

The detailed operation of step 7 will be described with reference to FIG.
In step 71, the total number of travel history data sorted and stored in step 5 is counted. Next, the number of stop data among the travel history data is counted (step 73).
In step 75, the ratio of the number of stop data to the total number of data is calculated from the number of all data counted in step 71 and the number of stop data counted in step 73. The calculation result is specified as a stop ratio at the target intersection in the route, and the specified result is stored in the stop ratio storage unit 10 (step 77).

FIG. 11 shows an intersection stop ratio specifying device 21 as another example. In FIG. 11, the same elements as those in FIGS. 7 and 8 are denoted by the same reference numerals, and the description thereof is partially omitted.
FIG. 11 shows an intersection stop ratio specifying device 21 that can specify a stop ratio at a target intersection for each condition specified in advance. That is, the device 21 is different in that the stop rate specifying unit 12 is replaced with a stop rate specifying unit 9 in the intersection stop rate specifying device 1 shown in FIG.
The stop ratio specifying unit 12 includes a 1-1 all data counter 121 and a 1-2 all data counter 125 in place of the first all data counter 91 in the stop ratio specifying unit 9. Further, instead of the first stop data counter 92, a 1-1 stop data counter 122 and a 1-2 stop data counter 126 are provided. Furthermore, instead of the first calculation unit 93, the 1-1 calculation unit 123 and the 1-2 calculation unit 127 are replaced with the first specification unit 94, and the 1-1 specification unit 124 and 1-2. A specifying unit 128 is provided.

The 1-1st all data counter 121 counts the number of travel history data that matches the first condition among the travel history data stored in the first route storage unit 81.
The 1-1st stop data counter 122 counts the number of travel history data that matches the first condition among the stop data of the travel history data stored in the first route storage unit 81.
The 1-1 calculating unit 123 calculates the ratio of the number of data counted by the 1-1 stop data counter 122 to the number of data counted by the 1-1 all data counter 121.
The 1-1 identifying unit 124 identifies the result of the calculation as a stop ratio. The identified stop ratio is stored in the stop ratio storage unit 10 in association with the condition and the route.
Similarly to the above, the 1-2 total data counter 125, the 1-2 stop data counter 126, the 1-2 calculating unit 127, and the 1-2 specifying unit 128 function and store in the first route storing unit 81. Among the travel history data, the stop ratio at the target intersection of the travel history data that matches the second condition is specified.

  In the intersection stop ratio specifying device 21, the predesignated condition is that the first condition is stopped at the passing intersection, and the second condition is passed without stopping at the passing intersection. The number of all data counters, stop data counters, calculation units, and specific units corresponding to the first route storage unit 81 to the nth route storage unit 8n may be appropriately provided according to the number of conditions. If the stop ratio at the target intersection is specified based on such a condition, it is possible to specify the stop ratio that more reflects the interlocking timing of the traffic lights at the passing intersection and the target intersection. That is, for example, when a vehicle traveling on a guidance route stops at a passing intersection, a driver who is stopped at the intersection (passing intersection) by guiding the stop ratio specified based on the first condition at the target intersection The stop rate at the next passing intersection (target intersection) can be accurately reported.

As another example, the first condition may be a weekday (Monday to Friday), and the second condition may be a holiday (Saturdays, Sundays, and holidays). The condition may be appropriately specified according to the purpose, and may be, for example, a travel time zone, a day of the week, a travel lane, weather, or the like. When traveling lanes and weather conditions are used, the traveling history data includes lane-specific information, regional weather information, wiper and headlight operation information, or such information is included in the traveling history data. If they are associated, they can be counted for each condition.
Furthermore, the designated condition may be a signal waiting stop time at the target intersection. For example, the stop ratio is specified by setting the first condition as a stop time of less than 10 seconds, the second condition as a stop time of 10 seconds or more and less than 30 seconds, and the third condition as a stop time of 31 seconds or more. The specified stop ratio can be guided along with the signal waiting stop time or the corresponding condition. The number of the specified conditions may be 1 or 2 or more.

FIG. 12 shows an intersection stop ratio specifying device 31 as another example. In FIG. 12, the same elements as those in FIGS. 7, 8, and 11 are denoted by the same reference numerals, and description thereof is partially omitted.
The intersection stop ratio specifying device 31 shown in FIG. 12 further includes a cost setting unit 15 and a cost storage unit 16 in the intersection stop ratio specifying device 1 shown in FIG.
Based on the stop ratio of the target intersection stored in the stop ratio storage unit 10, the cost setting unit 15 sets a cost in association with the route at the node corresponding to the target intersection. The cost is stored in the cost storage unit 16. Based on the cost set in this way, it is possible to hierarchize traffic signalized intersections with specified stop ratios. By using hierarchized intersection information with traffic lights, it is possible to provide a fuel-saving guide route that can travel more smoothly in route guidance in a navigation system. In addition, for target intersections that have a high rate of stopping in advance, excessive fuel consumption can be suppressed by removing the intersection (or the route near the intersection) from the guidance route, or performing deceleration driving advice before the intersection. It becomes possible.
