FIG. 1 is a block diagram showing an example of a walking route information presentation system 100 according to the present invention. As shown in FIG. 1, a walking route information presentation system 100 in this embodiment includes a terminal 1, a vehicle 2, a server 3, and a network 4 that constitutes a telecommunications network. The terminal 1 , the vehicle 2 , and the server 3 exchange information with each other through wireless communication via the network 4 . In the system of this embodiment, the person who operates the terminal device 1 is a user (human being). Further, although two vehicles 2 are shown in FIG. 1, the number of vehicles 2 in this embodiment is not particularly limited, and the system of this embodiment can be configured with a plurality of vehicles 2. . Hereinafter, one vehicle 2 will be described as an example, but the same applies to other vehicles 2 as well.

The system of this embodiment is applied to a part of the dispatch system for the vehicle 2. The vehicle 2 dispatch system is a system that dispatches the vehicle 2 to a user who has requested the use of the vehicle 2. A user can request the use of the vehicle 2 by operating the terminal 1 . The server 3 has a vehicle allocation function that allocates the vehicle 2 to a predetermined location in response to a usage request from a user.

Here, with reference to FIG. 2, an overview of the dispatch system for the vehicle 2 will be explained, and the role of the walking route information presentation system 100 in the dispatch system for the vehicle 2 will be explained. FIG. 2 is a diagram for explaining an overview of the vehicle dispatch system.

First, an overview of the dispatch system for the vehicle 2 will be explained. The user U1 shown in FIG. 2 is thinking of using the vehicle dispatch system to travel from the request point P0 to the destination P3. Therefore, the user U1 makes a vehicle allocation request (also referred to as a vehicle allocation request) to the server 3 via the terminal device 1 shown in FIG. Also, at this time, the user U1 inputs at least information about the destination P3 into the terminal device 1. If the terminal device 1 is equipped with a current position detection device, the terminal device 1 transmits to the server 3 at least the request for dispatch, the current position of the user U1 (request point P0), and the position information of the destination P3. When the server 3 receives various information from the user U1, it specifies a vehicle 2 that can be used by the user U1 from among the plurality of vehicles 2 based on the position information of the request point P0 and destination P3. At this time, if the user U1 specifies a usage time, the server 3 specifies a vehicle 2 that can be used during the designated time period.

When the server 3 specifies the vehicle 2 (hereinafter also referred to as the dispatched vehicle 2 ^' ) to be dispatched to the user U1, the server 3 determines the point where the user U1 gets on the dispatched vehicle 2 ^' (boarding point P1), and the location where the user U1 is seated in the dispatched vehicle. A point at which the dispatched vehicle 2 ^' will get off the vehicle (disembarkation point P2) is set, and a route for the dispatched vehicle 2' to travel from the boarding point P1 to the disembarkation point P2 is calculated as a travel route TR1.

The server 3 transmits, via the terminal 1, the position information of the pick-up point P1 and the drop-off point P2, information regarding the dispatched vehicle 2 ^' (vehicle type, scheduled arrival time of the dispatched vehicle 2' to the pick-up point P1, and the arrival time of the dispatched vehicle 2 ^' to the pick-up point P1, and the information about the dispatched vehicle 2' to the pick-up point P1 and the drop-off point P2). (e.g., the estimated arrival time of the dispatched vehicle 2 ^' ) is presented to the user U1. The user U1 confirms the presented positional information of the pick-up point P1 and the drop-off point P2, and moves from the request point P0 to the pick-up point P1 so as to arrive at the pick-up point P1 by the scheduled arrival time of the dispatched vehicle 2 ^' . Thereafter, the user U1 gets on the dispatched vehicle 2 ^' at the boarding point P1 and travels to the disembarking point P2. When the user U1 gets off the dispatch vehicle 2 ^' at the alighting point P2, the user U1 moves from the alighting point P2 to the destination P3.

The above is an overview of the dispatch system for the vehicle 2. Next, the role of the walking route information presentation system 100 in the above vehicle dispatch system will be explained. In the vehicle dispatch system, a user needs to travel from a request point P0 to a boarding point P1 and from a drop-off point P2 to a destination P3 by some means of transportation. The walking route information presentation system 100 selects a route (hereinafter referred to as This is a system that presents information regarding walking routes (also called walking routes) to the user. Examples of means of transportation along the walking route include walking and using a wheelchair. On the other hand, the means of transportation for the walking route in this embodiment does not include means such as bicycles, automobiles, taxis, buses, trains, etc., which require a transfer when using the allocated vehicle 2.

In the example of FIG. 2, before the boarding point P1 and the getting off point P2 are determined, the user U1 is given a walking route WR1 (the walking route from the request point P0 to the boarding point P1) and a walking route WR2 (the getting off point P2). information regarding the walking route (from the destination P3 to the destination P3) is presented. The information regarding the walking route WR1 includes route information (route information) of the walking route WR1, position information of the boarding point P1, and attribute information of the walking route WR1. Further, the information regarding the walking route WR2 includes route information (route information) of the walking route WR2, position information of the alighting point P2, and attribute information of the walking route WR2. Details of each piece of information will be described later. Furthermore, in the following description, information regarding walking routes will also be referred to as walking route information.

In the walking route information presentation system 100 of this embodiment, the user U1 can check information regarding the walking route WR1 and information regarding the walking route WR2 via the terminal device 1. Furthermore, when information regarding a plurality of walking routes is presented to the user, the user can select a boarding point and alighting point. In the example of FIG. 2, the user U1 refers to a plurality of walking route information (including a plurality of boarding points and a plurality of alighting points) and selects one boarding point P1 and one alighting point P2. Then, the server 3 sets the boarding point P1 and the getting off point P2 selected by the user U1.

In this way, the walking route information presentation system 100 according to the present embodiment presents the walking route information to the user in advance before the boarding point and the alighting point are set in the vehicle dispatch system, and allows the user to know the boarding point and the alighting point. This is a system for making choices. The above is an overview of the walking route information presentation system 100 of this embodiment.

Returning to FIG. 1 again, each configuration of the walking route information presentation system 100 will be described.

For example, when a user performs an operation on the input device 11 to request dispatch of the vehicle 2, information on the dispatch request is input to the information processing device 15. The vehicle allocation requesting unit 152 transmits a vehicle allocation request signal to the server 3 due to a user's operation.

In the above, it was explained that the means of transportation for the walking route does not include means (such as bicycles) that require changing when using the assigned vehicle 2, but it is possible to reach the final destination using these means. An example will be explained below. For example, if a user wants to use vehicle 2 and return home using a bicycle parked at a bicycle parking lot, the user can set the bicycle parking lot as destination P3 when using the dispatch system. , you can travel by bicycle from the bicycle parking lot to your home. Note that the above description is only one example of how the walking route information presentation system 100 is used, and does not limit the usage method.

In the above, it was explained that the means of transportation for the walking route does not include means that require changing when using the assigned vehicle 2, but this is an example of how to reach the final destination using these means.

It will be done. Various information detected by the on-vehicle sensor group 21 is transmitted to the ECU 22.

The ECU 22 is a vehicle-mounted computer called an electronic control unit (ECU). The ECU 22 has an autonomous driving function that causes the vehicle 2 to travel autonomously.

The ECU 22 uses an autonomous driving function to cause the vehicle 2 to autonomously travel along a predetermined driving route. For example, the ECU 22 controls a drive device (not shown) mounted on the vehicle 2 so that the vehicle 2 autonomously travels along a travel route transmitted from the server 3 . In this embodiment, the driving route transmitted from the server 3 includes a boarding point where the user gets on the vehicle 2 and a getting off point where the user gets off the vehicle 2. Note that the boarding point may match the request point. If the vehicle 2 can arrive at the requested point as is, the boarding point matches the requested point. An example of such a scene is a scene where a user requests a ride at a location facing a public road (on a sidewalk, inside a building). Further, the alighting point may coincide with the user's final destination (hereinafter also simply referred to as destination). If the vehicle 2 can arrive at the destination as is, the drop-off point matches the destination. An example of such a scene is a scene where the user's home faces a public road and the user has set the entrance of the user's home as the destination. Further, the technology for autonomously driving the vehicle 2 is not particularly limited, and the technology at the time of filing of this application can be used as appropriate.

The sidewalk information and facility information are used for walking route specifying processing, usability degree calculation processing, etc. in the control device 33, which will be described later.

The sidewalk information includes, for example, whether the road has a sidewalk, whether the road type is a pedestrian-only road, whether there is a step on the sidewalk, and if there is a step, the information about the step. number of steps, whether the sidewalk has a roof or arcade, whether pedestrian crossings are equipped with pedestrian signals, and whether structures such as guardrails are installed between the sidewalk and the roadway. Information on the slope angle of the sidewalk, the number of curves on the sidewalk, the width of the sidewalk, and the length of the sidewalk may be listed.

In addition, facility information includes, for example, the type of facility (house, public facility, commercial facility, etc.), the available hours or business hours of the commercial facility in the case of a commercial facility, the number of facilities in a specific section of the road (POI (also called numbers). Note that POI is an abbreviation for Point of Interest.

Next, the server communication device 32 is a device that can communicate with the terminal device 1 and the vehicle 2 via the network 4. The server communication device 32 outputs information received from the terminal device 1 or the vehicle 2 to the control device 33, and transmits information input from the control device 33 to the terminal device 1 or the vehicle 2.

Further, the server communication device 32 acquires information regarding the walking environment when the user uses the vehicle 2 from various servers existing on the network 4 . For example, the server communication device 32 acquires weather information or weather forecast information when the user uses the vehicle 2 from a server that manages weather information. This information can be segmented by time and/or region. The server communication device 32 acquires this information in order to specify the walking environment in which the user walks in weighting coefficient processing by the control device 33, which will be described later. Specifically, the server communication device 32 acquires weather information for the region belonging to the requested point and destination during the time period in which the user uses the vehicle 2 .

Further, for example, the server communication device 32 acquires road congestion information from a server that manages traffic information. Road congestion information is information indicating in what time zone a road is congested, and is information that can be subdivided by road type and/or time zone. The server communication device 32 acquires this information in order to specify the walking environment when the user uses the vehicle 2 in weighting coefficient processing by the control device 33, which will be described later. Specifically, the server communication device 32 acquires traffic congestion information for the region belonging to the requested point and destination during the time period in which the user uses the vehicle 2 .

Further, for example, the server communication device 32 acquires suspicious person information from a server managed by a national organization (for example, the Metropolitan Police Department). Suspicious person information is information indicating which area and at which time period a suspicious person is likely to appear, and is information that can be subdivided by area and/or time period. The server communication device 32 acquires this information in order to specify the walking environment when the user uses the vehicle 2 in weighting coefficient processing by the control device 33, which will be described later. Specifically, the server communication device 32 acquires suspicious person information for the area belonging to the requested point and destination during the time period in which the user uses the vehicle 2 .

Further, for example, the server communication device 32 acquires street light information from a server that manages street lights (also referred to as street lights or road lighting) provided on roads. Street light information is information about the installation interval of street lights installed on roads, the lighting hours of street lights, and the average brightness of street lights in specific sections, and is information that can be subdivided by region. be. The server communication device 32 acquires this information in order to specify the walking environment when the user uses the vehicle 2 in weighting coefficient processing by the control device 33, which will be described later. Specifically, the server communication device 32 acquires street light information of the region belonging to the request point and destination.

Further, for example, the server communication device 32 acquires event information from a server that manages event information. Event information is information that indicates what scale (e.g. capacity) of an event will be held in which region and time zone, and information that can be subdivided by region and/or time zone. It is. The server communication device 32 acquires this information in order to specify the walking environment when the user uses the vehicle 2 in weighting processing by the control device 33, which will be described later. Specifically, the server communication device 32 acquires event information of the area belonging to the requested point and destination during the time period in which the user uses the vehicle 2 . Note that the type of event is not particularly limited.

The control device 33 is composed of a computer equipped with hardware and software, and includes a ROM (Read Only Memory) that stores a program, a CPU (Central Processing Unit) that executes the program stored in this ROM, and an accessible computer. It is composed of a RAM (Random Access Memory) that functions as a storage device. Note that as an operating circuit, an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. can be used instead of or in addition to the CPU. .

As shown in FIG. 1, the control device 33 includes a vehicle allocation request reception unit 331, a walking route identification unit 332, a usability degree calculation unit 333, a walking route extraction unit 334, a walking route information transmission unit 335, and a vehicle allocation A management unit 336 is included, and these blocks implement each function described later by software established in the ROM.

The functions of the vehicle allocation request reception unit 331 will be explained. The vehicle allocation request reception unit 331 receives a vehicle allocation request from a user. As described above, when the user performs an operation on the terminal device 1 to request a vehicle allocation, the terminal communication device 13 of the terminal device 1 transmits a vehicle allocation request signal to the server 3 . The vehicle allocation request receiving unit 331 detects that the user is requesting vehicle allocation based on the vehicle allocation request signal inputted via the server communication device 32 .

Next, the function of the walking route specifying section 332 will be explained. Based on the vehicle allocation request signal and the map information 311, the walking route specifying unit 332 selects a plurality of walking routes for the user to travel on his/her own among the routes the user takes to reach the final destination using the vehicle 2. Identify candidates. In other words, the walking route candidate is a route for the user to travel before getting on the vehicle 2 and after getting off the vehicle. To explain using the example of FIG. 2, the walking route candidates include a walking route WR1 candidate from the request point P0 to the boarding point P1, and a walking route WR2 candidate from the alighting point P2 to the destination P3. . Note that the walking route indicates a route that can be walked by an unspecified number of people, and is not a route that is limited to a limited means of transportation. The user moves along the walking route not only on foot but also in a wheelchair.

In addition, in this embodiment, there are cases where there are multiple walking routes from the request point to the boarding point because the boarding points are different, and cases where there are multiple walking routes from the request point to the boarding point because the boarding points are the same point but different routes. This includes any case where there are multiple walking routes to the point. Similarly, multiple walking routes include cases where there are multiple walking routes from the drop-off point to the destination because the drop-off points are different, and cases where the drop-off point is the same point but different routes so there are multiple walking routes from the drop-off point to the destination. This includes any case where there are multiple routes.

Next, identification of walking route candidates from the request point to the boarding point will be explained. For example, the walking route specifying unit 332 specifies a plurality of places within a predetermined range around the request point where the vehicle 2 can stop. The predetermined range is a range determined experimentally. Further, a place where the vehicle 2 can stop is a place where a user can get on the vehicle 2 and a place where the vehicle 2 can stop within a range that complies with traffic regulations. Note that the type of location is not particularly limited. For example, the walking route specifying unit 332 may specify a road consisting of a sidewalk and a roadway as a place where the vehicle 2 can stop, or a specific station where the vehicle 2 is waiting (also known as a waiting station). ) may be specified as a place where the vehicle 2 can stop.

When identifying a plurality of places where the vehicle 2 can stop, the walking route identifying unit 332 identifies a walking route from the request point to the location for each of the identified locations. Thereby, the walking route identifying unit 332 identifies a plurality of walking route candidates that exist between the request point and the boarding point. Note that when executing this process, the walking route specifying unit 332 may limit the number of walking route candidates based on a certain standard. For example, the walking route specifying unit 332 creates a unique walking route that proceeds from the request point to the opposite side of the place where the vehicle 2 can stop, and then turns around at a predetermined place to reach the place where the vehicle 2 can stop. You may also perform exclusion processing. This makes it possible to limit the number of walking route candidates, thereby reducing the computational load.

Next, identification of walking route candidates from the drop-off point to the user's destination will be described. For example, the walking route identifying unit 332 identifies multiple locations within a predetermined range around the destination where the vehicle 2 can stop. When the walking route specifying unit 332 specifies a plurality of places where the vehicle 2 can stop, the walking route specifying unit 332 specifies a walking route from the specified place to the user's destination for each specified place. Thereby, the walking route identifying unit 332 identifies a plurality of walking route candidates that exist from the alighting point to the user's destination. Note that the predetermined range from the boarding point and the predetermined range from the disembarkation point may be the same range or may be different ranges.

Next, the function of the usability degree calculation unit 333 will be explained. The usability degree calculating unit 333 calculates the usability degree for each walking route candidate specified by the walking route specifying unit 332 based on the attribute information of the walking route. The usability degree in this embodiment is an index (indicator) indicating whether the user can move without feeling stress while reaching the boarding point or destination.

Situations where the user is likely to feel stress include, for example, if the walking distance is long or the slope of the sidewalk is steep, the user may feel exhausted and stressed while reaching the boarding point or destination. It becomes easier. Furthermore, depending on the environment in which the user travels along the walking route, the ease with which the user feels stress differs even on the same walking route. For example, if you walk immediately after seeing a suspicious person, walk through a crowd, walk with an umbrella in the rain, or walk on a poorly lit road at night, you may miss the boarding point or destination. During the process, the user feels anxious and becomes easily stressed. Although the description has been given of situations in which stress is likely to be felt due to differences in the walking environment, the above description is merely an example and is not particularly limited. In the following description, the usability degree will also be referred to as the user's suitability for the walking route. The attribute information of the walking route will be described later.

Here, an example of usability degree calculation processing will be described using FIG. 3. Further, specific details of the weighting coefficient processing in FIG. 3 will be explained using FIGS. 4A and 4B. FIG. 3 is an example of usability degree calculation processing. As shown in FIG. 3, the usability degree calculation unit 333 calculates the usability degree for each walking route candidate by sequentially performing attribute information input processing, weighting coefficient processing, and summing processing.

The usability degree calculation unit 333 executes attribute information input processing. Attribute information is information indicating attributes of a walking route. Attribute information consists of, for example, walking distance (walking route length) and walking environment (weather/temperature, time of day, facilities, events) as shown in Figure 3, and each piece of information is quantified. . The numerical value of the attribute information is an index indicating how appropriate the user is for the walking route, and the higher the numerical value, the higher the degree of appropriateness of the user. That is, the higher the numerical value of the attribute information, the lower the possibility that the user will feel stressed. Hereinafter, an example of attribute information of a walking route will be explained. Note that the walking route attribute information used in the explanations of FIGS. 3, 4A, and 4B is part of the sidewalk information and facility information, and is not particularly limited. The usability degree calculation unit 333 can configure the attribute information of the walking route using information other than the information used in the explanation of FIGS. 3, 4A, and 4B based on other sidewalk information and facility information.

"Walking distance" as attribute information is a parameter indicating the length of a walking route. The numerical value of the walking distance is a numerical value that is uniquely set without any factors that vary with respect to the walking route. For example, the shorter the walking distance, the higher the value of the walking distance is set. This is because the shorter the walking distance, the less likely the user will feel tired before boarding the vehicle 2 or after getting off the vehicle 2 and arriving at the destination. This is based on the perspective that there is a low possibility of causing stress to people.

On the other hand, the numerical value of the walking environment in the attribute information varies depending on the walking environment (for example, weather, temperature, time of day, etc.) when the user uses the vehicle 2. How the numerical value of the attribute information is changed according to the walking environment will be described later. Here, each parameter represented as the walking environment will be explained.

"Weather/Temperature" as attribute information is a parameter that indicates the high possibility that the user will not be stressed even when walking in bad weather environments such as rain, snow, blizzard, typhoon, and strong winds. It is. For example, if an arcade is provided on a walking route, the numerical value of the attribute information will be higher than that of a walking route without an arcade. This is based on the viewpoint that in the case of a walking route provided with an arcade, for example, even on rainy days, the user can walk without using an umbrella, and therefore the possibility of causing stress to the user is low. Although an arcade has been described as an example of a passageway that can shelter from the rain, a roof may be used as a walking route within a facility.

Moreover, the "time of day" as attribute information is a parameter indicating the high possibility that the user will not be stressed even when walking during the night time. For example, if street lights are provided at regular intervals along a walking route, the numerical value of the attribute information will be higher than that of a walking route where no street lights are provided. This is because if the walking route is equipped with street lights, the user can walk on a path that is brightly lit by the street lights, even if it is night time, so it is unlikely to cause stress to the user. This is based on this perspective. Furthermore, the narrower the installation interval between street lights, the higher the value of the attribute information. Moreover, the higher the average value of the brightness of the street lights in a specific section, the higher the numerical value of the attribute information becomes.

Furthermore, "facility" as attribute information is a parameter indicating the high possibility that the user will not be stressed even when walking in an area that makes the user anxious. For example, if a plurality of commercial facilities are provided along a walking route, the numerical value of the attribute information will be higher than that of a walking route in which no commercial facilities are provided. This is because, in the case of a walking route with multiple commercial facilities, for example, even if the user has to walk through an area where suspicious persons are frequent, the user can feel secure knowing that he or she can evacuate to the commercial facility. This is based on the viewpoint that the possibility of causing stress to the user is low. Furthermore, the larger the number of facilities, the higher the numerical value of the attribute information. Furthermore, the greater the number of facilities to which the user can evacuate, the higher the numerical value of the attribute information.

In addition, "event" as attribute information is a parameter that indicates the high possibility that users will not feel stressed even if they walk during a time when the number of people in the area temporarily increases due to an event being held. It is. For example, in the case of a walking route that does not include any facilities that can serve as event venues, the numerical value of the attribute information will be higher than that of a walking route around the facility. This is because in the case of a walking route that does not have mixed factors, for example, even if the area around the venue is temporarily crowded due to an event being held, the user can avoid walking in the crowd. This is based on the perspective that the possibility of causing stress is low.

The usability degree calculation unit 333 executes weighting coefficient processing for each walking route candidate. The weighting coefficient process is a process for adjusting numerical values of attribute information in accordance with the walking environment when the user uses the vehicle 2. An example of weighting coefficient processing will be described later.

Then, when the weighting process is completed, the usability degree calculation unit 333 adds up the numerical values of the attribute information for each walking route candidate. The usability degree calculation unit 333 takes the total value of the attribute information as the usability degree. In this way, the degree of suitability of the user for the walking route is quantified. The example in FIG. 3 shows that among walking route candidates A to C, walking route candidate C with the highest total value of attribute information is the walking route with the highest degree of appropriateness for the user. .

4A is a diagram showing an example of the weighting coefficient process in FIG. 3, and FIG. 4B is a diagram showing another example of the weighting coefficient process in FIG. 3. The example in FIG. 4A is a situation in which the user requests a ride at request point O at 6:00 pm after sunset when the weather is rainy. In this scene, the usability degree calculation unit 333 calculates the walking route candidate A (the walking route from the request point O to the boarding point candidate A) and the walking route candidate B (the walking route from the request point O to the boarding point candidate A process (weighting coefficient process) for changing the weighting coefficient according to the walking environment in which the user uses the vehicle 2 is executed for each of the walking routes (to point candidate B).

The upper table shown in FIG. 4A shows the numerical values of the attribute information of walking route candidate A and walking route candidate B before performing the weighting coefficient process. Since this is before the weighting coefficient is adjusted, all the weighting coefficients are uniformly set to "1" regardless of the type of attribute information. The usability degree calculation unit 333 executes attribute information input processing for each walking route candidate based on the sidewalk information and facility information included in the map information 311, and creates the upper table shown in FIG. 4A.

The usability degree calculation unit 333 acquires weather information of the region to which the request point belongs via the server communication device 32 in order to understand the walking environment when the user uses the vehicle 2. Further, the usability degree calculation unit 333 acquires time information that the server 3 has. Then, the usability degree calculation unit 333 adjusts the numerical value of the weighting coefficient in order to calculate the usability degree corresponding to the walking environment when the user uses the vehicle 2.

In the example of FIG. 4A, since "weather: rain" and "time zone: 6:00 p.m. (after sunset)" are used, the usability degree calculation unit 333 calculates the "weather/temperature" and "time zone" of the attribute information. Change the weighting coefficient from "1" to "2". As a result, the values of "weather/temperature" and "time zone" each become twice the value before weighting coefficient processing is performed. This is because, considering the weather and time of day when the user uses Vehicle 2, the parameters of "weather/temperature" and "time of day" among the attribute information of the walking route have a large effect on the stress on the user. It is based on perspective. The usability degree calculation unit 333 executes weighting coefficient processing to create the lower table shown in FIG. 4A.

Then, the usability degree calculation unit 333 calculates the total value of the attribute information of each of the walking route candidate A and the walking route candidate B by executing a summing process. Thereby, the usability degree calculation unit 333 calculates a usability degree corresponding to the walking environment when the user uses the vehicle 2 for each walking route candidate. In the example of FIG. 4A, as a result of changing the weighting coefficient by weighting coefficient processing, the usability level of walking route candidate A to boarding point candidate A with a roof is lower than that of walking route candidate B to outdoor boarding point candidate B. calculated higher than the usability rating of

Other examples will be explained. The example in FIG. 4B is a scene in which a user requests a ride at a request point P during a time period when an event is being held. In this scene, the usability degree calculation unit 333 calculates the walking route candidate C (the walking route from the request point P to the boarding point candidate C) and the walking route candidate D (the walking route from the request point P to the boarding point candidate C) specified by the walking route specifying unit 332. Weighting coefficient processing is performed for each of the walking routes (walking route to point candidate D).

The upper table shown in FIG. 4B shows the numerical values of the attribute information of the walking route candidate C and the walking route candidate D before executing the weighting coefficient process. All weighting coefficients are unified at "1" regardless of the type of attribute information. The usability degree calculation unit 333 executes attribute information input processing for each walking route candidate based on the sidewalk information and facility information included in the map information 311, and creates the upper table shown in FIG. 4B.

The usability degree calculation unit 333 acquires event information of the region to which the request point belongs via the server communication device 32 in order to understand the walking environment when the user uses the vehicle 2. Further, the usability degree calculation unit 333 acquires time information that the server 3 has. Then, the usability degree calculation unit 333 adjusts the numerical value of the weighting coefficient in order to calculate the usability degree corresponding to the walking environment when the user uses the vehicle 2.

In the example of FIG. 4B, since "time zone: event is being held", the usability degree calculation unit 333 changes the weighting coefficient of "event" in the attribute information from "1" to "2". As a result, the value of "event" becomes twice the value before weighting coefficient processing is performed. This is based on the viewpoint that, considering the time period during which an event is being held, the parameter of "event" among the attribute information of the walking route has a large effect on the stress on the user. The usability degree calculation unit 333 executes weighting coefficient processing to create the lower table shown in FIG. 4B.

Then, the usability degree calculation unit 333 calculates the total value of each of the attribute information of the walking route candidate C and the walking route candidate D by executing a summation process. Thereby, the usability degree calculation unit 333 calculates a usability degree corresponding to the walking environment when the user uses the vehicle 2 for each walking route candidate. In the example of FIG. 4B, as a result of changing the weighting coefficient by weighting coefficient processing, the usability degree of the walking route candidate C to the boarding point candidate C is calculated to be higher than the usability degree of the walking route candidate D to the boarding point candidate D. Ru. In the example of FIG. 4B, the boarding point candidate C is located at a distance from the event venue, so the surrounding area is not crowded even during the event time. Further, since boarding point candidate D is located near the event venue, it is included in an area that is crowded during the event time period.

In addition, in the example of FIG. 4A and FIG. 4B, in addition to the above-mentioned "walking distance" and "walking environment", "pedestrian facility" is included as attribute information. "Pedestrian facilities" is a parameter that indicates the number of facilities or equipment provided for pedestrians along a walking route. installation rate of equipment). For example, in the case of a walking route where the installation rate of pedestrian signals is high relative to the number of crosswalks, the value of the attribute information will be higher than that of a walking route where no pedestrian signals are installed at the crosswalks. . This is because in the case of walking routes with a high rate of pedestrian traffic lights, users can walk without being overly concerned about the presence of vehicles such as cars, motorcycles, and bicycles when crossing a crosswalk, which can be stressful for users. This is based on the viewpoint that there is a low possibility that the The numerical value of the pedestrian facility according to this embodiment is uniquely set according to the walking route, similarly to the numerical value of the walking distance.

Next, the function of the walking route extraction section 334 will be explained. The walking route extraction unit 334 extracts a walking route to present to the user from among the plurality of walking route candidates specified by the walking route identification unit 332 based on the usability degree calculated by the usability degree calculation unit 333. do.

The walking route extraction unit 334 extracts the corresponding walking route candidate when there is a walking route candidate whose usability degree is equal to or higher than a predetermined value among the plurality of walking route candidates. The number of walking route candidates to be extracted is not particularly limited, and may be one or more. Further, the predetermined value is a value determined experimentally.

In addition, when there is a walking route candidate with a usability degree equal to or higher than a predetermined value, the walking route extraction unit 334 selects an efficient route for the server 3 or the user from among the plurality of walking route candidates, regardless of the numerical value of the usability degree. Extract walking route candidates. An efficient walking route in this embodiment is a walking route that takes the shortest time to dispatch the vehicle 2 (for example, a walking route to a boarding point where the vehicle 2 can arrive in the shortest time), and a walking route where the user The walking route is at least one of the walking routes with the minimum travel cost (for example, the walking route with the shortest walking distance). The reason for extracting walking routes that seek efficiency regardless of the degree of usability is to widen the range of options for users.

For example, based on the road congestion information acquired by the server communication device 32, the walking route extraction unit 334 provides the server 3 with an efficient walking route to the boarding point where the vehicle 2 can arrive in the shortest time. Calculate as a walking route. Further, for example, the walking route extracting unit 334 identifies a walking route candidate with the shortest walking distance from information on the distance of each walking route. Then, the server 3 calculates the specified walking route as an efficient walking route for the user.

On the other hand, if there is no walking route candidate with a usability level equal to or higher than a predetermined value among the plurality of walking route candidates, the walking route extracting unit 334 selects a walking route candidate from among the plurality of walking route candidates to the server 3 or the user. Extract efficient walking route candidates. The number of walking route candidates to be extracted is not particularly limited, and may be one or more.

Next, the function of the walking route information transmitter 335 will be explained. The walking route information transmitting unit 335 transmits information regarding one or more walking route candidates extracted by the walking route extracting unit 334 to the terminal device 1 as walking route information via the server communication device 32. The walking route information includes route information (route information) of the walking route, positional information of boarding and disembarking points, and attribute information of the walking route. As described above, the information presentation unit 153 of the terminal device 1 outputs the walking route information received via the terminal communication device 13 to the output device 12, thereby presenting the walking route information to the user.

FIG. 5A is an example of walking route information presented to the user. In the example of FIG. 5A, the walking route extraction unit 334 extracts the walking route candidate B as a walking route whose usability degree is a predetermined value (for example, 15) or more, and also extracts the walking route candidate B as an efficient walking route for the server 3 or the user. It is assumed that walking route candidate A has been extracted (see the table at the bottom for the usability degree of each walking route candidate). The terminal device 1 presents two pieces of walking route information regarding the drop-off point to the user who has requested the dispatch.

In the example of FIG. 5A, the user selects either walking route candidate A or walking route candidate B as the walking route to destination C during the late night hours. Walking route candidate A has a shorter walking distance than walking route candidate B and can reach destination C in the shortest time, but is darker than walking route candidate B. On the other hand, walking route candidate B has a longer walking distance than walking route candidate A and takes time to reach destination C, but is a walking route that is brighter than walking route candidate A. The user is also presented with the attribute information of the walking route, so by comparing the attribute information of walking route candidate A and the attribute information of walking route candidate B, the user can check whether walking route candidate B has a long walking distance. I can understand the reasons given. In the example of FIG. 5A, the user selects walking route candidate A or walking route candidate B by comprehensively determining the time of day, walking distance, brightness, and the like.

Further, FIG. 5B is another example of walking route information presented to the user. In the example of FIG. 5B, there is no walking route with a usability degree equal to or higher than a predetermined value (for example, 15). Therefore, it is assumed that the walking route extraction unit 334 extracts walking route candidate A and walking route candidate B as efficient walking routes for the server 3 or the user (as for the usability degree of each walking route candidate, (see table below). The terminal device 1 presents two pieces of walking route information regarding the drop-off point to the user who has requested the dispatch.

In the example of FIG. 5B, the user selects either walking route candidate A or walking route candidate B as the walking route to destination C in the morning time slot. Walking route candidate A is a walking route that can reach destination C in a shorter time than walking route candidate B. Furthermore, walking route candidate B is a walking route that takes longer to reach destination C than walking route candidate A. In the case of the example in FIG. 5B, unlike the example in FIG. 5A, since it is during the daytime, the user selects walking route candidate A or walking route candidate B without considering the brightness when walking. .

Next, the functions of the vehicle allocation management section 336 will be explained. The vehicle allocation management unit 336 instructs the vehicle 2 to move, etc., and causes the vehicle 2 to be allocated to the boarding point selected by the user. For example, when a user selects one pick-up point and a drop-off point, the vehicle dispatch management unit 336 selects a vehicle 2 that can arrive at the pick-up point in the shortest time from among the plurality of vehicles 2 as a dispatch vehicle 2 ^' . Specify as. Then, the vehicle allocation management unit 336 calculates the travel route until arriving at the boarding point and the travel route from the boarding point to the drop-off point, and communicates the boarding point, the drop-off point, and each travel route via the server communication device 32. information is sent to dispatch vehicle 2 ^' . Further, the vehicle dispatch management unit 336 transmits a movement instruction to the dispatch vehicle 2 ^′ to start moving to the boarding point via the server communication device 32 . Further, the vehicle allocation management unit 336 transmits information regarding the allocated vehicle 2 ^′ (vehicle type, etc.) to the terminal device 1 as allocated vehicle information via the server communication device 32 .

Next, an example of a time chart from when the user makes a dispatch request until the user and the dispatched vehicle 2 ^' move to the boarding point will be explained using FIG. 6. Further, an example of the process related to walking route information executed by the server 3 will be explained using FIG. 7.

In step S1, a user requests a vehicle allocation. The information processing device 15 of the terminal device 1 transmits a vehicle allocation request signal to the server 3 via the terminal communication device 13. The vehicle allocation request signal includes information indicating a vehicle allocation request as well as positional information of the requested point and destination.

In step S2, the server 3 receives the vehicle allocation request signal transmitted from the terminal 1 in step S1. Then, in step S3, the server 3 executes processing regarding walking route information. The specific contents of the process will be described later using FIG. 7.

When the process in step S3 is completed, the process advances to step S4. The server 3 transmits walking route information, which is the processing result of step S3, to the terminal device 1 via the server communication device 32.

In step S5, the terminal device 1 receives walking route information. The walking route information includes route information (route information) of the walking route, positional information of boarding and disembarking points, and attribute information of the walking route. Walking route information is information regarding one or more walking route candidates.

In step S6, the terminal device 1 presents the walking route information received in step S5 to the user. For example, as shown in FIG. 5A or 5B, the information processing device 15 of the terminal device 1 superimposes the route of the walking route candidate, the position of the drop-off point candidate, and the position of the destination on a still image of the map and displays it ( (equivalent to the output device 12) is displayed. Further, the information processing device 15 causes the display to display walking route attribute information for each walking route candidate, as shown in FIG. 5A or 5B. Note that the same display method can be applied to the walking route candidates from the request point to the boarding point candidates.

In step S7, the boarding point and the alighting point are determined by the user. For example, when a plurality of walking route candidates are displayed on the display of the terminal device 1 in step S6, the user selects a walking route candidate from among the plurality of walking route candidates based on the situation when the user uses the vehicle 2, the user's convenience, etc. At the same time, a walking route from the request point to the boarding point and a walking route from the alighting point to the destination are selected. Note that the user may select corresponding boarding point candidates and alighting point candidates without selecting a walking route candidate.

In step S8, the terminal device 1 transmits information (location information) about the boarding point and the alighting point selected by the user in step S6 to the server 3, and in step S9, the server 3 transmits the boarding point information from the terminal device 1 and receive information on the drop-off point.

In step S10, the server 3 identifies a vehicle 2 that can be dispatched to the user as a dispatch vehicle 2 ^' from among the plurality of vehicles 2, based on the positional information of the boarding point and the disembarkation point received in step S9. Furthermore, the server 3 calculates a travel route from the current position of the dispatched vehicle 2 ^' to the boarding point in order for the specified dispatched vehicle 2 ^' to move to the boarding point. Further, the server 3 calculates a travel route from the boarding point to the alighting point in order to move the dispatched vehicle 2 ^' from the boarding point to the alighting point.

In step S11, the server 3 transmits information regarding the dispatch vehicle 2 ^' (dispatch vehicle information) to the terminal device 1. The dispatched vehicle information includes information for the user to specify the dispatched vehicle 2 ^' , such as the vehicle type and color of the dispatched vehicle 2 ^' .

In step S12, the terminal device 1 receives dispatched vehicle information from the server 3. In step S13, the terminal device 1 causes the display to display the dispatched vehicle received in step S12. This allows the user to understand the characteristics of the vehicle 2 that will be delivered to the boarding point. In step S14, the user starts moving to the boarding point.

Moreover, when the process of step S11 is completed, the server 3 executes the process of step S15. In step S15, the server 3 transmits a movement instruction to the dispatched vehicle 2 ^' to move the dispatched vehicle 2 ^' to the boarding point. In step S16, the ECU 22 of the dispatched vehicle 2 ^' causes the dispatched vehicle 2 ^' to start moving to the boarding point.

Next, details of step S3 shown in FIG. 6 will be explained using FIG. 7. FIG. 7 is a flowchart showing processing related to walking route information executed by the server 3.

In step S21, the server 3 identifies multiple walking route candidates. For example, the server 3 identifies multiple locations within a predetermined range from the request point where the vehicle 2 can stop. Then, the server 3 specifies a plurality of walking route candidates by specifying a walking route from the request point to the possible stopping point of the vehicle 2 for each of the identified points.

In step S22, the server 3 calculates the usability degree for each walking route candidate identified in step S21. For example, as shown in FIG. 3, the server 3 executes an input process for inputting attribute information corresponding to each walking route candidate. Then, the server 3 executes weighting coefficient processing as adjustment processing to match the walking environment when the user uses the vehicle 2. For example, as shown in FIG. 4A, if the weather or the time of day is said to have a large effect on stress on the user, the server 3 assigns weighting coefficients for "weather/temperature" and "time of day" among the attribute information. Set to a larger value than the weighting coefficients of other attribute information. When the weighting coefficient process is completed, the server 3 executes a summing process of summing up the numerical values of the attribute information for each walking route candidate, as shown in FIG. Thereby, as shown in FIGS. 3, 4A, and 4B, the usability degree is calculated for each walking route candidate.

In step S23, the server 3 determines whether there is a walking route candidate whose usability degree is equal to or higher than a predetermined value based on the processing result of step S22. The predetermined value is an experimentally determined value. If there is a walking route candidate whose usability degree is equal to or higher than the predetermined value, the process advances to step S24. On the other hand, if there is no walking route candidate with a usability degree equal to or higher than the predetermined value, the process advances to step S27.

In step S23, if there is a walking route candidate with a usability degree equal to or higher than the predetermined value, the process proceeds to step S24. In step S24, the server 3 extracts walking route candidates whose usability degree is equal to or higher than a predetermined value from among the plurality of walking route candidates identified in step S21.

In step S25, the server 3 extracts walking route candidates that are efficient for the server 3 or the user. For example, the server 3 extracts, from among the plurality of walking route candidates, a walking route candidate that includes a boarding point where the user can arrive in the shortest time as an efficient walking route candidate for the user. Further, for example, the server 3 sends a walking route candidate including a boarding point where the dispatched vehicle 2 ^' can arrive in the shortest time from among the plurality of walking route candidates to the server 3 as an efficient walking route. Extract as a candidate.

In step S26, the server 3 prepares information regarding the walking route candidates extracted in each of steps S24 and S25 as walking route information.

In step S23, if there is no walking route candidate with a usability degree equal to or higher than the predetermined value, the process advances to step S27. In step S27, the server 3 extracts walking route candidates that are efficient for the server 3 or the user, similar to the process in step S25.

In step S28, the server 3 prepares information regarding the walking route candidates extracted in step S27 as walking route information.

As described above, the walking route information presentation system 100 according to the present embodiment includes the server 3 having the dispatch function of moving the vehicle 2 to a predetermined point in response to a user's request, the database 31 storing map information 311, It includes a terminal device 1 that can be operated by a user. Based on the user's request and the map information 311, the server 3 identifies a plurality of walking routes for the user to move before getting on and after getting off the vehicle 2, and for each walking route, the server 3 specifies a plurality of walking routes for the user to move before getting on and after getting off the vehicle 2, and for each walking route, the Then, the degree of usability of the walking route is calculated, and walking route information corresponding to the degree of usability is presented to the user via the terminal device 1. Thereby, the user can select a boarding point and alighting point from the viewpoint of usability according to the walking environment when using the vehicle 2. As a result, useful and appropriate information can be provided to the user who has requested a ride.

Furthermore, in the present embodiment, if there is a walking route with a usability level greater than or equal to a predetermined value, the server 3 presents the user with information regarding the walking route whose usability degree is greater than or equal to the predetermined value. This allows the user to select a walking route that satisfies a certain standard of usability. The user can arrive at the destination using the vehicle 2 without feeling excessively stressed by the dispatch system.

Furthermore, in this embodiment, the attribute information of the walking route includes the distance of the walking route, the time of day when the user uses the vehicle 2, the weather when the user uses the vehicle 2, facilities provided along the walking route, and the road on which the user walks. Thereby, the walking route can be evaluated in consideration of the walking environment when the user uses the vehicle 2.

In addition, in this embodiment, the server 3 calculates the usability degree according to the distance of the walking route. Thereby, for example, the usability degree of a walking route with a short walking distance can be calculated to be higher than the usability degree of a walking route with a long walking distance. When a user walks along a walking route with a relatively short walking distance, the user can walk without getting tired compared to when the walking distance is long, so the degree of stress experienced by the user can be appropriately quantified. As a result, it is possible to realize a vehicle dispatch system that is highly convenient for users.

Furthermore, in the present embodiment, if the time period when the user is walking corresponds to the lighting time of the street lights, the server 3 selects at least one of the number of installed street lights and the brightness of the street lights. Calculate the usability level accordingly. Thereby, for example, the usability degree of a walking route where street lights are provided at regular intervals can be calculated to be higher than the usability degree of a walking route where no street lights are provided. When a user walks on a relatively bright walking route, the user can walk with more peace of mind than when walking on a relatively dark walking route, so the degree of stress experienced by the user can be appropriately quantified. As a result, it is possible to realize a vehicle dispatch system that is highly convenient for users.

In addition, in this embodiment, the server 3 calculates the usability degree depending on whether an arcade or a roof is installed when the weather is rainy or snowy. Thereby, for example, the usability degree of a walking route provided with an arcade can be calculated to be higher than the usability degree of an outdoor walking route not provided with any arcade. When users walk without an umbrella, they can walk without worrying about getting their clothes wet compared to when walking with an umbrella, so it is possible to appropriately quantify the degree of stress experienced by the user. . As a result, it is possible to realize a vehicle dispatch system that is highly convenient for users.

Furthermore, in the present embodiment, the server 3 calculates the usability degree according to at least one of the number of facilities provided along the walking route and whether the facilities are evacuable. Thereby, for example, the usability degree of a walking route along which commercial facilities are provided can be calculated to be higher than the usability degree of a walking route where no commercial facilities are provided. When a user walks along a walking route where there is a place to evacuate in the event of an emergency, the user can walk with more peace of mind than when there is no place to evacuate. Can be quantified. As a result, it is possible to realize a vehicle dispatch system that is highly convenient for users.

Furthermore, in the present embodiment, the server 3 calculates the usability degree depending on at least one of whether the walking route is for pedestrians only and the presence or absence of suspicious person information in the area to which the walking route belongs. do. Thereby, for example, the usability degree of a walking route exclusively for pedestrians can be calculated to be higher than the usability degree of a walking route along a roadway. When a user walks on a pedestrian-only road, the user can walk with peace of mind without paying attention to the presence of other vehicles, so the degree of stress experienced by the user can be appropriately quantified. As a result, it is possible to realize a vehicle dispatch system that is highly convenient for users.

In addition, in the present embodiment, if there is a walking route with a usability degree equal to or higher than a predetermined value, the server 3 extracts an efficient walking route for the server 3 or the user from among the plurality of walking routes, In addition to information on walking routes with a usability level equal to or higher than a predetermined value, information on extracted efficient walking routes is presented to the user. As a result, for example, a user who wants to rush to a destination can select a walking route that will allow him or her to reach the boarding point in the shortest time. As a result, it is possible to realize a practical vehicle dispatch system that can respond to the user's circumstances.

Furthermore, in the present embodiment, when there is no walking route with a usability level equal to or higher than a predetermined value, the server 3 extracts an efficient walking route for the server 3 or the user from among the plurality of walking routes. The user is presented with information regarding the efficient walking route that they have taken. Even in situations where the user may be under some degree of stress, information regarding the walking route from an efficient perspective can be presented as an alternative.

Furthermore, in this embodiment, the efficient walking route for the server 3 is the walking route that takes the shortest time to dispatch the vehicle 2 and the walking route that requires the least operational cost to dispatch the vehicle 2. At least one of them is a walking route. Thereby, information regarding the walking route can be presented from an efficient viewpoint for the server 3.

In addition, in this embodiment, the walking route that is efficient for the user is at least one of the walking route that takes the shortest walking time for the user and the walking route that requires the least amount of travel cost when the user uses a vehicle. It is one of the walking routes. This makes it possible to present information regarding the walking route from an efficient viewpoint for the user.

Furthermore, in the present embodiment, the walking route includes at least one of the boarding point of the vehicle 2 and the alighting point of the vehicle 2, and the information regarding the walking route includes the walking route and the attribute information of the walking route. This allows the user to check not only the location of the boarding point or alighting point, but also the walking route leading to the boarding point or destination and the attribute information of the walking route. You can select the location and drop-off location.

Note that the embodiments described above are described to facilitate understanding of the present invention, and are not described to limit the present invention. Therefore, each element disclosed in the above embodiments is intended to include all design changes and equivalents that fall within the technical scope of the present invention.

For example, in the above embodiment, when explaining the method for calculating the usability degree, in the weighting coefficient processing, the configuration in which the weighting coefficient is changed from "1" to "2" using the examples of FIGS. 4A and 4B is described. Although the explanation has been given as an example, the rate at which the weighting coefficients are changed is not particularly limited. For example, even when the weather is rainy, the rate at which the weighting coefficient is changed may be changed depending on the amount of precipitation. For example, when the amount of precipitation is relatively large, the weighting coefficient may be changed at a higher rate than when the amount of precipitation is relatively small. Furthermore, even during the night time period, the rate at which the weighting coefficients are changed may be changed based on a specific reference time. For example, in the case of a quiet time period from 11:00 pm to 12:00 pm, compared to the time period from 7:00 pm to 8:00 pm when there is a lot of traffic, even if the weighting coefficient is changed at a higher rate, good. As a result, the degree of usability can be calculated with high accuracy, so it is possible to realize a vehicle dispatch system that is more convenient for users.

Further, for example, in the above embodiment, the configuration in which the user selects the boarding point and the alighting point is explained as an example, but the selection of the boarding point and the alighting point may be performed as a process of the server 3. For example, if there is a walking route candidate with a usability level equal to or higher than a predetermined value, the server 3 may set a boarding point or alighting point included in the walking route candidate as the boarding point or alighting point of the user. Furthermore, when there are a plurality of corresponding walking route candidates, the server 3 can also prioritize and select a walking route candidate with a higher degree of usability.
