(Embodiment)
1 to 9 are diagrams for explaining the embodiment. Hereinafter, embodiments will be described along the following flow with reference to these drawings. First, an outline of the entire embodiment will be described in “1”. Then, “2” will be used to explain the system configuration with specific examples of hardware and software configurations. In “3”, the flow of processing will be described. In “4” and below, effects and the like according to the present embodiment will be described.

(1 Overview)
FIG. 1 is a diagram illustrating a schematic configuration of the information processing system 1. As shown in FIG. 1, the information processing system 1 includes a mobile terminal 100 (mobile terminals 100A to 100E are collectively referred to as a mobile terminal 100), an information processing server 200, and a base station 300. The information processing server 200 and the base station 300 are each connected to the public network N. The public network N may be any type of network as long as the mobile terminal 100 and the information processing server 200 can communicate with each other. As a specific example of the public network N, for example, a mobile phone network can be considered in addition to the Internet.

  The mobile terminal 100 is, for example, a mobile phone (whether it is a so-called feature phone or a smartphone), a tablet information terminal, a node PC (PErsonal Computer), a car navigation device attached to an automobile, or the like. This is a movable information processing terminal.

  Here, the information processing system 1 according to the present embodiment has a function of transmitting a route search request in which conditions such as a departure place and a destination are set from the mobile terminal 100 to the information processing server 200. The information processing server 200 that has received the route search request refers to the link information 213 that is information about the road, searches for a route that matches the condition, and transmits the search result to the mobile terminal 100. The mobile terminal 100 displays the search result on a map, for example.

  Here, the link information 213 managed by the information processing server 200 includes information related to a temporary stop line on each road. Since it is expected that the required time will increase when passing on a road including a temporary stop line, the information processing server 200 increases the search cost according to the route search condition. Thereby, depending on route search conditions, it is possible to make it difficult to select a road having a number of temporary stop lines as a selected route. Also, the travel time from the starting point to the destination by following the route is increased according to the presence of the temporary stop line. Thereby, the travel time calculated by the information processing server 200 can be brought close to the actual travel time.

  In addition, the information processing server 200 according to the present embodiment sequentially receives position information obtained by associating latitude and longitude information measured every second, for example, with a measurement time from the mobile terminal 100. The information processing server 200 manages a collection of the position information as probe information 215. Thereby, it becomes possible to specify at which time each portable terminal 100 was located. In addition, if the probe information 215 is analyzed, the proportion of correctly stopped on the temporary stop line (hereinafter referred to as the temporary stop rate), the traffic volume of each road, the average speed, and the average stopped at the temporary stop line. It becomes possible to specify the stop time and the like. The information processing server 200 uses these pieces of information to identify points on a temporary stop line to be careful of, consider these pieces of information in route search, or calculate travel time by taking statistical information into account. You can also do it.

(2 System configuration)
Hereinafter, the functional configuration of the information processing system 1 according to the present embodiment will be described with reference to FIGS. 2 to 6. FIG. 2 is a diagram illustrating a functional configuration of the information processing system 1 according to the present embodiment. As described above, the information processing system 1 includes the mobile terminal 100 and the information processing server 200. Hereinafter, these configurations will be described. In FIG. 2, the base station 300 is not shown.

First, the configuration of the mobile terminal 100 will be described. As shown in FIG. 2, the mobile terminal 100 includes a main control unit 110, a wireless communication unit 120, an input unit 130, a display unit 140, and a sensor 150.

  The main control unit 110 controls various processes in the mobile terminal 100 and includes a CPU 111 and a memory 113 (including a volatile memory and a non-volatile memory). In the main control unit 110, programs such as various applications including a route search application are stored in the storage area of the memory 113, and the CPU 111 executes programs such as the applications, thereby causing the mobile terminal 100 to have various functions. Can be realized. A functional configuration of software executable by the main control unit 110 will be described later with reference to FIG.

  The wireless communication unit 120 can transmit and receive data to and from other information processing apparatuses via the public network N. The wireless communication unit 120 executes a route search request to the information processing server 200 and reception of the search result from the information processing server 200 under the control of the main control unit 110.

  The input unit 130 is a device that accepts input from the user to the mobile terminal 100 and includes an input key, a touch panel, and the like. The input unit 130 may have a function of receiving voice from the user and outputting the input information to the main control unit 110 as input information.

  The display unit 140 is, for example, a display device for displaying various information such as route search condition input and route search results and presenting them to the user. The display unit 140 can be realized by, for example, a liquid crystal display or an organic EL (Electro Luminescence).

  The sensor 150 outputs a detection signal that changes according to the movement state of the user of the mobile terminal 100, and includes, for example, an acceleration sensor 151 and a GPS receiver 153. Specifically, the detection signal output from the sensor 150 includes acceleration information indicating the acceleration output from the acceleration sensor 151 and latitude / longitude information indicating the current position of the mobile terminal 100 output from the GPS receiver 153. included.

  Next, a functional configuration of software executed on the mobile terminal 100 will be described with reference to FIG. FIG. 3 is a diagram illustrating a functional configuration of software executed on the mobile terminal 100. The software of the portable terminal 100 according to the present embodiment is roughly divided into a search condition setting unit 161, a map drawing unit 163, and an operation input unit 165.

  The search condition setting unit 161 sets a departure point, a destination, a route search method, a search consideration condition, and the like according to a user input via the operation input unit 165, and processes a route search request according to the setting. It transmits to the server 200.

  Here, as a route search method that can be set by the search condition setting unit 161, for example, “recommended route search” in which time and distance are balanced, “general road priority route search” giving priority to general roads, wide road width Any one of “Road width priority route search” that gives priority to routes, “Distance priority route search” that gives priority to short routes, and “Bypass route search” that preferentially selects routes that are not selected by any of the above route search methods May be set.

  As the search consideration conditions that can be set by the search condition setting unit 161, for example, traffic jam consideration for avoiding a congested road as much as possible, time zone regulation consideration that considers traffic regulation by time zone, and the like can be considered. Further, in the information processing system 1 according to the present embodiment, consideration is given to pauses for setting whether or not to consider a pause line in the search cost setting, and caution / risk points for avoiding places where accidents are likely to occur as much as possible. Consideration can also be set by the search condition setting unit 161.

  FIG. 4 shows a specific example of a setting screen for the user to set search consideration conditions. In the example of FIG. 4, the user can select “consideration of traffic jam”, “consideration of time zone regulation”, “consideration of temporary stop”, “consideration of caution / danger point”, and the like.

  The map drawing unit 163 draws, for example, a search route obtained as a result of the route search request transmitted from the search condition setting unit 161 to the information processing server 200 on the map. In addition to this, the map drawing unit 163 may display the number of pause lines and the like existing on the route. Further, the map drawing unit 163 may provide a navigation service to the user based on the route.

  The map drawing unit 163 in the present embodiment may have a function of calling attention at a position such as a temporary stop line where an accident is likely to occur when a map is presented. FIG. 5 shows a specific example of a display screen drawn by the map drawing unit 163. For example, if there is a situation such as a low temporary stop rate, a high accident rate, a high traffic volume on the road to be crossed, or a high traveling speed, the information processing server 200 sends information to that effect to the mobile terminal 100. By transmitting, the portable terminal 100 arranges the icon 51 for alerting on the map screen.

  The operation input unit 165 transmits an operation signal from the user input from the input unit 130 to various software functions such as the search condition setting unit 161 and the map drawing unit 163.

  The position information transmission unit 167 measures the position (latitude and longitude) of the mobile terminal 100 using the sensor 150 at a predetermined interval such as every second, and associates the latitude and longitude information with the positioning time to the information processing server. 200.

(2.2 Information processing server 200)
As described above, the information processing server 200 is an information processing apparatus having a function of performing a route search in response to a request from the mobile terminal 100 and transmitting the result to the mobile terminal 100. As illustrated in FIG. 2, the information processing server 200 includes a control unit 220, a communication unit 230, and a database (DB) 210. The function of the information processing server 200 can also be realized as a system in which two or more information processing devices (including a server) are combined. It is also conceivable to incorporate the function of the information processing server 200 on the mobile terminal 100 side.

  The control unit 220 includes a CPU (Central Processing Unit) 221 and a memory 223 which are arithmetic devices. The control unit 220 stores various programs (software) stored in the memory 223 and executes the programs on the CPU 221 to control various processes in the information processing server 200. For example, in response to a route search request from the mobile terminal 100 received by the communication unit 230, the control unit 220 controls a function of transmitting a route search result that matches the conditions, map drawing data 211, and the like to the mobile terminal 100. To do.

The communication unit 230 is a communication interface for communicating with the mobile terminal 100. For example, the communication unit 230 receives a route search request from the mobile terminal 100. In addition, the communication unit 230 transmits a route search result, map drawing data 211 corresponding to the route search result, and the like to the mobile terminal 100.
The DB 210 is an information management module configured on a storage device, for example, and manages the map drawing data 211, the link information 213, and the probe information 215.

  The map drawing data 211 can include latitude / longitude information, polygon data, figure type information, layer ID, annotation data, and the like. The information processing server 200 can cause the mobile terminal 100 to draw a map by transmitting such information to the mobile terminal 100.

  The link information 213 is a database that manages roads that the user can pass as links. The information processing server 200 provides the route search service to the mobile terminal 100 by searching for the link information 213. FIG. 6 shows a specific example of the link information 213.

The link information 213 can include ID information 213a, start point information 213b, end point information 213c, pause line information 213d, distance information 213e, search cost information 213f, travel time information 213g, and the like.
The ID information 213a is an identifier uniquely assigned to each link.

  The start point information 213b and end point information 213c are information relating to the latitude and longitude of the start point and end point of the road corresponding to the link, the identifier assigned to the connection point (intersection), and the like. By confirming the start point information 213b and the end point information 213c, it is possible to confirm to which other road the road corresponding to each link is connected.

The temporary stop line information 213d is information regarding the temporary stop line on the road corresponding to each link. For example, it is conceivable that the pause line information 213d includes information such as the number of pause lines, the position, and the distance from the start point / end point.
The distance information 213e is information regarding the length of the road corresponding to each link.

  The search cost information 213f is search cost information set for the road corresponding to each link. In general, for example, the search cost is set higher for a link corresponding to a long road. The search cost may be set for each route search method. As a result, the search cost for road width priority route search is set low for links corresponding to wide roads, or the search cost for general road priority route search is set high for highway links. be able to.

  The travel time information 213g is information relating to how much time is required to actually move on the road corresponding to the link. For example, the travel time is set according to distance, road width, speed limit, and the like. If the travel times of the links on the route obtained as a result of the search are added together, it is possible to calculate the travel time when traveling from the departure point to the destination through the route.

  Subsequently, the probe information 215 will be described with reference to FIG. FIG. 7 is a diagram illustrating a specific example of the probe information 215. The probe information 215 includes terminal ID, coordinate information (latitude and longitude information), and positioning time information as shown in FIG. The information processing server 200 analyzes the probe information 215 to determine whether the vehicle on which the person holding the portable terminal 100 rides is temporarily stopped on the stop line, how long the vehicle has been stopped, and the road It is possible to know the average speed, traffic volume, etc.

  Next, a functional configuration of software executed by the information processing server 200 will be described with reference to FIG. FIG. 8 is a block diagram illustrating a functional configuration of software executed by the information processing server 200. The software of the information processing server 200 according to the present embodiment includes a search cost setting unit 241, a search request receiving unit 243, a route search unit 245, a travel time calculation unit 247, a search result transmission unit 249, a temporary stop rate determination unit 251, traffic An amount calculation unit 253, an average speed calculation unit 255, and a warning position specifying unit 257 are included.

  The search cost setting unit 241 sets the search cost stored in the search cost information 213f for each road expressed as the link information 213. Here, the search cost setting unit 241 can set the search cost using the temporary stop line information 213d included in the link information 213. More specifically, it is conceivable to add a predetermined search cost for a road including a temporary stop line. It is conceivable that the search cost to be added according to the temporary stop line can be changed depending on the route search method. For example, for “recommended route search”, “general road priority route search”, and “detour route search”, the search cost is increased by 5 seconds according to the presence of a temporary stop line, and “road width priority route search” and “distance priority search” are increased. With regard to “route search”, it may be possible not to change the search cost even if a temporary stop line exists.

  In addition, by using the result of statistically processing the ratio of actually stopping on the pause line and the time during which the pause was stopped by the pause rate determination unit 251, the search cost setting unit 241 can respond to the pause line. You may make it change the cost to add and travel time. In this case, for example, the higher the pause rate or the longer the pause time, the higher the search cost. Further, the travel time information 213g set in the link information 213 may be changed accordingly.

  The search request receiving unit 243 receives a route search request from the mobile terminal 100. The route search unit 245 performs route search using the link information 213 in response to the route search request received by the search request reception unit 243. More specifically, the search request receiving unit 243 searches for a combination of links that can reach the destination from the departure place, and then calculates the total value of the search costs for each combination. The route search unit 245 can use the route information having a low total search cost obtained as a result as the route that best matches the search condition.

  In the route search request received from the mobile terminal 100, when “temporary stop consideration” is specified, the search cost set by the search cost setting unit 241 for each link is set before the route search. You may switch whether to change according to a temporary stop line. In addition, when “considering caution / danger point” is designated, a high cost is required for a link that passes a caution / danger point specified by a warning position specifying unit 257 described later before performing a route search. May be set in the search cost setting unit 241.

  The travel time calculation unit 247 calculates the travel time for the route obtained as a result of searching by the route search unit 245. More specifically, the travel time calculation unit 247 calculates the total travel time of the route by referring to the travel time information 213g included in the link information 213 of each link constituting the route and summing them. Can do.

  The search result transmission unit 249 transmits information such as the route search result searched by the route search unit 245 and the travel time related to the route of the search result calculated by the travel time calculation unit 247 to the mobile terminal 100.

  The temporary stop rate determination unit 251 determines the temporary stop rate and the temporary stop time on the temporary stop line using the probe information 215 stored in the DB 210. This is because, for example, the probe information 215 of the portable terminal 100 that is considered to be passing through the pause line is analyzed, and a plurality of pieces of position information having continuous time at the position of the pause line are transmitted from the same portable terminal 100. It can be determined by whether or not it exists. A pause line with a low pause rate can be determined as a warning position where an accident is likely to occur.

  The traffic volume calculation unit 253 determines the traffic volume of each road using the probe information 215 stored in the DB 210. For example, the traffic volume of the road can be determined by statistically analyzing the probe information 215 of the mobile terminal 100 that is considered to be passing on the road. On a road that intersects a road with a large amount of traffic, the intersection can be determined as a warning position where an accident is likely to occur.

  The average speed calculation unit 255 determines the average speed passing through each road using the probe information 215 stored in the DB 210. For example, the average speed of a car or the like passing through the road can be determined by statistically analyzing the probe information 215 of the mobile terminal 100 that is considered to be passing on the road. On a road that intersects a road with a high average speed, the intersection can be determined as a warning position where an accident is likely to occur.

  The warning position specifying unit 257 is configured to calculate the temporary stop rate calculated by the temporary stop rate determination unit 251, information on the accident occurrence position / accident occurrence rate (not shown), and the traffic volume of the road to be crossed in the temporary stop line before the intersection. Based on at least a part of the average speed or the like, a point where an accident is likely to occur, that is, a warning point (warning position) is specified. For example, the search result transmission unit 249 transmits the specified warning position to the mobile terminal 100, so that the mobile terminal 100 can be notified to the user through a screen as illustrated in FIG.

(3 Process flow)
Hereinafter, the processing flow of the information processing server 200 will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of processing of the information processing server 200 related to route search.

  Each processing step to be described later can be executed in any order or in parallel as long as there is no contradiction in processing contents, and other steps can be added between the processing steps. good. Further, a step described as a single step for convenience can be executed by being divided into a plurality of steps, and a step described as being divided into a plurality of steps for convenience can be executed as one step.

  When the search request receiving unit 243 receives a route search request from the mobile terminal 100 (S901), the search cost setting unit 241 sets a search cost according to the request for each link (S903). For example, when “pause consideration” is set, the search cost setting unit 241 sets a route search using a value obtained by adding a search cost according to the number of pause lines.

  The route search unit 245 performs route search using the search cost set according to the route search condition. As described above, this method specifies, for example, a combination of links that can reach from the departure point to the destination by referring to the link information 213, and calculates the sum of search costs in each combination to obtain the highest value. A route having a low value can be set as a search route that best matches the route search condition.

  Further, the travel time calculation unit 247 calculates the travel time for the route specified by the route search unit 245. This is obtained, for example, by summing the travel times set for the links corresponding to the roads constituting the route.

  The search result transmission unit 249 transmits the route search result by the route search unit 245 and the travel time information calculated by the travel time calculation unit 247 to the mobile terminal 100. At this time, if there is a point specified by the warning position specifying unit 257 as the warning position at the route place, the information may be transmitted to the mobile terminal 100.

(4 Effects of this embodiment)
As described above, according to the information processing system 1 according to the present embodiment, it is possible to perform route search and travel time calculation in consideration of the temporary stop line. This makes it possible to provide the user with more realistic travel times and suitable route search results.
