Description

  The present invention relates to a route display method for guiding a traveling vehicle.

  2. Description of the Related Art Advances in wireless mobile communication systems in recent years have made it possible to transmit and receive data to and from a moving object (vehicle or the like) that moves over a wide range. On the other hand, with the advance of the GPS (Global Positioning System) positioning technology, the position information of a traveling moving object can be instantaneously obtained with high accuracy. For this reason, various systems for monitoring the positions and running conditions of a plurality of vehicles by using these technologies are used. When the vehicle is a taxi or a transportation vehicle, a dispatch system for realizing an optimal dispatch situation by grasping such a situation is also used.

  For example, Patent Literature 1 discloses that a target area is divided into a plurality of dispatch areas, a priority is set for a vehicle (taxi) in each dispatch area, and a dispatch destination (location) designated at the time of dispatch is designated. ) And an AVM (Automatic Vehicle Monitoring) system for selecting a vehicle in consideration of not only the positional relationship of the vehicle but also this priority. As a result, it is possible to dispatch a vehicle optimal for the customer according to the characteristics of the dispatch area.

  Patent Document 2 discloses a system that recognizes, for each area, the presence or absence of an empty vehicle and allocates the vehicle that is recognized as empty. At this time, if there are a plurality of customers who request the dispatch at the same time, the dispatch is performed according to the information (waiting time, use frequency, etc.) regarding the customers.

  Such a dispatch instruction is performed by a management center (base station) wirelessly connected to a terminal (mobile station) mounted on the vehicle. At this time, the management center can recognize the dispatched vehicle and the traveling route to the dispatch destination. For example, when there are a plurality of vehicles that are empty and are estimated to have a short arrival time to the dispatch destination, the traveling route and the estimated arrival time are displayed for each vehicle as shown in FIG. Here, 001, 002, 003, and 004 are extracted as the vehicles that are empty around the station that is the dispatch destination (customer pickup destination) 100, and the shortest traveling route to each dispatch destination 100 is displayed. I have. Assuming that the traveling state of each vehicle is a standard one, the time required for traveling on the traveling route is displayed on the right side in the figure as the estimated arrival time of each vehicle. Here, the estimated arrival times are displayed in ascending order, and this order can be used as a priority when selecting a vehicle.

  In addition, not only the traveling route to the destination of the empty vehicle as described above, but also the traveling route from when the customer gets on the vehicle to when the customer arrives at the destination can be similarly displayed. This makes it possible to set a traveling route that minimizes the traveling time and minimizes the fare.

JP 2015-158830 A JP 2018-49408 A

  In the example of FIG. 7, for example, the vehicle 002 is preferentially selected mainly as the vehicle having the shortest estimated arrival time. However, the estimated arrival time greatly fluctuates depending on various factors such as the actual traffic congestion state and weather, or the state of surrounding entertainment. Actually, the specifications of the vehicles to be selected are not the same, and the vehicle with the shortest traveling distance is not always optimal.

  Further, for example, when the traveling place is a tourist spot and the customer is a tourist, it is not always preferable that the traveling route from getting on the vehicle to reaching the destination is the shortest. In this case, a traveling route that passes through a popular tourist spot is preferable even if the traveling distance is long.

  Therefore, as described above, when a traveling route is set only from the current positional relationship between the current position of the vehicle and the destination, or when a vehicle to be dispatched is selected, an inappropriate traveling route or vehicle is set. was there. For this reason, a route display method that makes it easy to select an appropriate traveling route according to the purpose has been desired.

  The present invention has been made in view of such circumstances, and has as its object to solve the above problems.

The present invention is a route display method for displaying a traveling route on which a vehicle travels on a map, wherein a plurality of points of interest, which are facilities or characteristic places that affect the setting of the traveling route, are selected, and the traveling route is selected. The included two-dimensional range on the map is divided into a plurality of first layer areas by a first layer division, and each of the first layer areas is further divided into a plurality of second layer areas by a second layer division. A first-layer attention point, which is the attention point in the first-layer area, is stored in correspondence with each of the first-layer areas, and a second-layer attention, which is the attention point in the second-layer area, is stored. Point-of-interest information in which points are stored in correspondence with each of the second-level areas is stored, and based on the point-of-interest information, when the traveling route enters one of the first-level areas, The point of interest of the first hierarchy corresponding to the first hierarchy area is displayed on the map, and when the travel route falls within one of the second hierarchy areas, the second hierarchy point corresponding to the second hierarchy area is displayed. It is characterized in that two-layer attention points are displayed on the map.
Further, in the point of interest information, valid / invalid can be set for at least one of the first-layer point of interest and the second-layer point of interest that have been set in advance, and the invalid-set point can be set. The first layer attention point and the second layer attention point may be set so as not to be displayed on the map.
Further, in the attention point information, a plurality of the first-layer attention points or a plurality of the second-layer attention points are set to correspond to numerical values, and based on the value of the numerical values, the first A priority order to be displayed in a plurality of the layer attention points or a plurality of the second layer attention points may be determined.
Further, each of the second hierarchical areas is further divided into a plurality of third hierarchical areas by a third hierarchical section, and in the attention point information, a third hierarchical attention point which is the attention point in the third hierarchy area Is stored in correspondence with each of the third hierarchy areas, and when the travel route falls within one of the third hierarchy areas, the third hierarchy attention point corresponding to the third hierarchy area is displayed on the map. May be displayed.

  ADVANTAGE OF THE INVENTION According to this invention, the route display method which can easily select the appropriate driving route according to the objective can be obtained.

It is a figure showing composition of the whole dispatch system in which the route display method concerning an embodiment is performed. FIG. 2 is a block diagram illustrating a configuration of a management center used in the vehicle allocation system. FIG. 3 is a block diagram illustrating a configuration of a mobile station on which a route display method according to an embodiment is executed. It is an example showing specific contents of attention point information used in the route display method according to the embodiment. It is an example of a display by the route display method according to the embodiment. It is an example showing a modification of attention point information used in the route display method according to the embodiment. It is an example of the display by the conventional route display method.

  Next, embodiments for carrying out the present invention will be specifically described with reference to the drawings. FIG. 1 shows an overall configuration of a vehicle allocation system in which a route display method according to an embodiment of the present invention is executed. Here, mobile stations 10A to 10E are used for the vehicles to be dispatched, respectively. Each of the mobile stations 10A to 10E is mounted on each vehicle in a one-to-one correspondence with the vehicle (taxi). Therefore, here, the mobile stations including the entire vehicle are described. Each of the mobile stations 10A to 10E has a position information recognition unit (not shown) that receives a GPS (Global Positioning System) signal emitted by the GPS satellite G and recognizes its own position information (latitude and longitude). As each mobile station, a dedicated wireless communication terminal can be used, but a mobile terminal such as a smartphone or a tablet terminal that is usually used can also be used.

  Wireless base stations 20A to 20Z are installed at a plurality of points on the ground, and each wireless base station can communicate with a mobile station near itself. For this reason, the radio base station with which the mobile station can communicate may change as the vehicle (mobile station) moves. In FIG. 1, mobile stations 10A to 10E can communicate with radio base station 20A within communicable range XA. Here, each mobile station transmits its own location information to the radio base station 20A. Further, each mobile station is connected to a toll meter of each vehicle, and the toll meter recognizes the state and information of the vehicle by automatic control according to the operation state (waiting for a signal, traffic congestion, etc.) and operation of a crew member. The state and information thus recognized are also transmitted from the mobile station to the radio base station 20A. The state and information of the vehicle recognized here include, for example, (1) "real vehicle" (a state where a customer is loaded and heading to a destination), (2) an empty vehicle (a state where no customer is loaded), and (3). “Scheduled to be vacant” (current scheduled vehicle vacancy time), (4) “Payment” (vehicle is stopped and payment processing is being performed), (5) “Break” ( Empty and the crew is resting).

  The radio base stations 20A to 20Z are connected to the management center 30 via a network NW. Therefore, the management center 30 can recognize the positions of the vehicles (mobile stations 10A to 10E) under the management via any of the radio base stations 20A to 20Z. Further, not only the position information but also the state and information of each vehicle as described above can be recognized. Such a position, state, and information of each vehicle are periodically recognized by the management center 30 in a short cycle.

  On the other hand, the customer connects to the dispatch center 40 connected to the management center 30 via the network NW and transmits a dispatch request to the management center 30. The dispatching center 30 is actually composed of a plurality of dispatching terminals 41A to 41Y connected to the network NW, and an operator operating each dispatching terminal inputs a customer request. The information (vehicle allocation information) input here includes customer specific information (name, number of people, etc.), vehicle allocation destination information (location where the customer wants to board), destination information (location name, facility name, etc.), vehicle allocation request There are time, desired car type, etc.

  When the management center 30 obtains the dispatch information from the dispatch center 40, the management center 30 provides the customer with information on the latest position, state, and vehicle of each vehicle (mobile station) at the time obtained as described above. A vehicle to be dispatched is selected, and the dispatch information is transmitted to the mobile station of the vehicle. As a result, the crew of this vehicle can recognize that he / she has been selected, and the dispatch destination and customer to go to thereafter. Here, in order to select a vehicle in this manner, the management center 30 can select a vehicle whose status is (2) “vacant” as described above. In addition to the above, (3) a vehicle whose time of “scheduled to be vacant” is near, and (4) a vehicle that is in a state of “payment” can also be selected. Further, among the vehicles satisfying the above requirements, the vehicle having the shortest arrival time to the dispatch destination can be given the highest priority. As described above, the management center 30 can also recognize the position information of the mobile station that has obtained the dispatch information while the mobile station is moving to the dispatch destination, and the mobile station (vehicle) arrives at the dispatch destination and enters a standby state. The management center 30 can also recognize that the vehicle has started traveling to the destination with the customer as information on the vehicle. Note that, depending on the number of customers, a plurality of vehicles may be selected at the same time. The dispatch information (request for dispatch from the customer side) can include the characteristics (vehicle type, color, etc.) of the desired vehicle, and in this case, these characteristics are also considered.

  Note that the configuration itself shown in FIG. 1 is common to the system described in, for example, Patent Document 1. In addition, the customer accesses the homepage of the taxi company, transmits information to the management center 30 using an application of the mobile terminal owned by the customer, or makes a telephone call to the automatic reception of the management center 30, for example, by a method such as The above-mentioned dispatch information can also be input to the management center 30 without going through the dispatch center 40.

  FIG. 2 is a block diagram showing the configuration of the management center 30 described above. The management center 30 includes three servers (map server 31, dispatch server 32, and database server 33) provided for each function.

  The map server 31 is a server that manages map information of all areas where each vehicle travels. When a departure point and a destination point are determined, a search for a route connecting them, a straight-line distance thereof, and a travel distance (a route distance) are performed. A route search unit 311 for calculating the total distance), the required travel time, and the like is provided.

  The dispatch server 32 is a server that dispatches vehicles using the map server 31 or a database server 33 described below. The dispatch server 32 dispatches a candidate vehicle search unit 321 that searches for a vehicle suitable for dispatch according to the dispatch information and a vehicle (mobile station) searched by the candidate vehicle search unit 321. And a dispatch instruction unit 322 for giving an instruction.

  The candidate vehicle search unit 321 selects a vehicle to be a candidate for vehicle allocation according to the above-mentioned vehicle allocation information and the position, state, and information of each vehicle (mobile station) recognized as described above. The dispatch instruction unit 322 transmits the dispatch information to the vehicle (mobile station) thus selected.

  At this time, the database server 33 instructs the selected mobile station on the traveling route from the current location of the vehicle to the dispatch destination and the traveling route from the dispatch destination to the destination, and displays them on the mobile station side. The present invention has a feature in the display method of the traveling route at this time. The data used for this purpose includes various types of information (area information) in the area where the vehicle travels, and the position, state, and information of each vehicle obtained from the mobile station as described above. An area information management unit 331 is provided for storing and managing the former, and a vehicle information managing unit 332 is provided for storing and managing the latter. As described above, the position, state, and information of the vehicle in the vehicle information management unit 332 are updated to the latest one in a short time.

  The vehicle dispatching system of the present invention is particularly characterized by the above-described method for displaying the traveling route. FIG. 3 is a diagram showing a configuration of the mobile station 10 (10A to 10E) for displaying the traveling route in this way. The mobile station 10 stores the wireless communication unit 12 for exchanging information with the management center 30 by wireless communication as described above, the position recognition unit 13 for recognizing its own position, and various data related to its own operation. The mobile station 10 includes a storage unit 14, an operation unit 15 operated by a crew of the vehicle, a display unit 16 for displaying various information such as a map and a traveling route, and a control unit 11 for controlling the entire mobile station 10 side.

  The control unit 11 causes the display unit 16 to display a travel route on a map based on the map information obtained from the management center 30 and the designated travel route. At this time, not only the traveling route is simply displayed on the map, but also a point of interest within the displayed range is displayed together with the traveling route based on the area information obtained from the management center 30 side. The point of interest is a facility or a characteristic place that affects the setting of the traveling route, and is a target that can be displayed together with the traveling route on a map. However, the number of noticeable points that can be displayed is limited so that the user can easily recognize its presence on the map, and thus the noticed points to be displayed are limited.

  Here, this point of interest is (X) that it is effective to recognize its existence within a wide range where the vehicle travels, and (Y) it is locally compared with the former within the range where the vehicle travels. It is classified into two types, those for which it is effective to recognize the existence. Examples of the former include famous sightseeing spots, restaurants, emergency evacuation sites, and the like. For example, it is often desirable for a tourist to recognize the presence of a famous tourist spot even when the distance from the current location is not short (when the vehicle is not in the vicinity). The same applies to restaurants and emergency evacuation sites.

  On the other hand, examples of the latter include a congestion area (a place where the frequency of occurrence of congestion is high), a caution area (a place where the accident occurrence rate is high), a convenience store, and a toilet. When it is easy to detour around the congested area or the caution area, it is sufficient to recognize the existence of the vehicle only when the vehicle is in the vicinity. In addition, since there are many convenience stores and toilets, it is sufficient to display only those near the vehicle. Conversely, when all of these objects are displayed in a wide range, the number of the displayed objects becomes too large, and it is difficult for the user to recognize the presence on the map.

  For this reason, in the management center 30, in correspondence with (X) that it is effective to recognize its existence within a wide range, the area division of the first hierarchy corresponding to this wide range is set. Then, in this area (first hierarchical area), the noted point (first hierarchical focused point) serving as (X) is set. Further, an area division of the second hierarchy in which this area is further finely divided is set, and in this area (sub-area: second hierarchy area), the above-mentioned attention point (second-layer attention point) serving as (Y) is set. It is set and stored in the database server 33 as point of interest information and used. FIG. 4 is a table showing a specific example of the attention points set corresponding to each area and sub-area as the attention point information set as described above.

  FIG. 5 is an example of display of the display unit 16 and the dispatch terminals 41A to 41Y of the dispatch center 40 using the route display method used here. Within the range displayed here, rectangular areas A (upper left), B (upper right), C (lower left), and D (lower right), which are first hierarchical areas, are set. As for the area A, rectangular sub-areas A1 (upper left), A2 (upper right), A3 (lower left), and A4 (lower right) are set as the second hierarchical area. Similarly, sub-regions B1 to B4, C1 to C4, and D1 to D4 are set for the regions B, C, and D, respectively. Each of the sub-regions is divided by a straight line as shown in the figure. However, as to the regions A to D, they correspond to a wide region as described above, and as shown, they overlap at adjacent portions. With parts. In FIG. 5, the instructed traveling route R is indicated by a thick solid line.

  In FIG. 4, in the areas A to D, (1) a sightseeing spot, (2) a restaurant, and (3) an emergency evacuation place are the above-mentioned (X) attention points (first-layer attention points). Types are set in common, and, for example, (1) a specific name of a tourist spot (castle A) in the area A is stored as detailed information of each point of interest. Also in the sub-area A1, as the noted points (second-layer focused points) serving as the above (Y), (11) traffic congestion area, (12) attention area, (13) convenience store (convenience store), (14) toilet Four types are commonly set, and specific names and the like are stored as detailed information of each point of interest. In FIG. 4, only the name (or not applicable) is described as the detailed information, but in reality, the accurate position information (latitude and longitude) is also stored as the point of interest information. Therefore, each of these points of interest can be displayed on the map of FIG. Further, in the table of FIG. 4, the description of the detailed information on the sub-regions A2 and A3 which are not related in the following example is omitted.

  Here, what kind of attention point is displayed can be selected by the user in advance. This setting can be made by selecting “valid / invalid” in FIG. For example, since the restaurant (2) in the area A in FIG. 4 is “invalid”, the display is not performed regardless of the traveling route R.

  In FIG. 5, the traveling route R passes through the areas A, B, and C, but does not pass through the area D. In the area A, the traveling route R passes only through the sub-area A4 and does not pass through the sub-areas A1 to A3. In addition, the traveling route R passes through the sub-regions B1 and B2 in the region B and does not pass through the sub-regions B3 and B4. In the area C, the traveling route R passes through the sub-areas C2 and C3 and does not pass through the sub-areas C1 and C4.

  In this route display method, only the points of interest in the area and sub-area through which the travel route R passes are displayed together with the travel route. Therefore, first, in the area A, (1) a sightseeing spot that is actually in the sub-area A1 is displayed as a first-layer attention point corresponding to the area A. In the sub-area A4 through which the travel route R passes, if there is a corresponding second-layer attention point, the target is displayed as the second-layer attention point. The two-layer attention point is not displayed.

  On the other hand, in the area B, (2) a restaurant and (3) an emergency evacuation site exist as the first-level attention points, but since the (2) restaurant is invalid, the sub-area B3 is actually inactive. (3) Only emergency evacuation sites are displayed. Further, as the second layer attention point, (11) a congestion area and (13) a convenience store are displayed in the sub area B1, and (12) a caution area is displayed in the sub area B2.

  In the area C, there is no corresponding target as the corresponding first-layer attention point. On the other hand, (12) caution area and (13) convenience store are displayed in the sub-area C2, and (11) congestion area is displayed in the sub-area C3, as the second-layer attention points.

  As described above, in the above route display method, since the attention point is selected and displayed for each of the area (the first hierarchy area) and the sub area (the second hierarchy area) smaller than the area, the necessary attention points are required. Only one can be selected and displayed. At this time, by setting the above “valid / invalid” in accordance with the purpose of setting the traveling route, it is possible to further narrow down and display more necessary points of interest. For example, when the traveling route R is set for dispatching and is to arrive at the dispatch destination in the shortest time, the traveling time in FIG. 4 is affected (11) congestion area, (12) All items other than the attention area may be invalidated.

  For this reason, according to the above-mentioned route display method, it is easy to select an appropriate traveling route according to the purpose. At this time, for example, in the techniques described in Patent Documents 1 and 2, information in the divided areas is used for vehicle allocation, whereas in the above-described route display method, the division of the areas is displayed. It is used to select a point of interest.

  Further, in the above example, after the targets set as the target points in advance are set as (1) to (3) and (11) to (14), the target points to be displayed are "valid / invalid" from among them. However, for example, “priority” in FIG. 4 may be set. In this case, first, only the attention point of priority 1 is displayed. For example, a user's operation on the operation unit 15 causes the attention point of priority 2 to be displayed, and further operation also causes the attention point of priority 3 to be displayed. It can be. At this time, for example, in the example of FIG. 4, in the area A, (1) only the sightseeing spot exists in the castle A, but (1) other facilities may similarly exist in the area A as the sightseeing spot. In such a case, each of these may be given a different priority. The same applies to the sub-region.

  When setting the “valid / invalid” and the priority in this way, a point of interest is set in advance in each area and sub-area, and only these settings are changed according to the user, the purpose of the route display, and the like. Can be. FIG. 6 shows an example of three types of settings (three users) in such a case. Here, the user 1 is, for example, an operation manager of the management center 30. In this case, since the safety management of the operation of the vehicle is the most important, (3) emergency evacuation places and (12) caution points are effective. And its priority is raised. The user 2 is, for example, a crew member of a vehicle. In this case, in consideration of the operation when a tourist is carried, (1) a tourist spot and (12) a caution point are effective and their priorities are made higher. The user 3 is, for example, a sightseeing tour organizer. In this case, the highest priority is given to the convenience of the tourist, and (1) the sightseeing spot and (14) the toilet are effective and the priority is high.

  In these cases, the target itself selected as the point of interest can be stored in the database server 33 in advance together with the setting of the region and the sub-region as common. After that, “valid / invalid” and the priority can be appropriately changed and used according to the user and the purpose of the route display.

  In FIG. 4, the importance is set as a point together with the priority (an integer after 1). For example, the degree of importance can be set such that, as opposed to the priority, a larger value is more likely to be displayed. In this case, the importance can be used not only for displaying the driving route but also for selecting the driving route. For example, as shown in FIG. 5, the importance of the point of interest displayed near the driving route R is accumulated, a plurality of types of driving routes R are set, and the accumulated values of the importance are compared. The management center 30 can also issue an instruction to adopt the changed traveling route. Similar to the above “valid / invalid” and the priority in FIG. 6, the importance can also be appropriately set according to the user, the purpose of route display or the purpose of route setting. Also in this case, the specific content of the point of interest can be used without changing a preset one. In this case, for example, attention points with low importance are not displayed when the distance from the traveling route R is longer than a certain value, and attention points with high importance are displayed even if this distance is longer than a certain value. In this way, the display can be performed in more detailed cases than in the case of the selection based on the priority described above.

  Further, as described above, it is effective to recognize the point of interest selected in each of the areas A to D within a wide range in which the (X) vehicle travels, and the number thereof is It is preferable that the recognition be performed in a small number of adjacent regions. For this reason, in FIG. 5, the regions A to D are not simply divided regions, but are set so as to overlap with each other at adjacent portions. As a result, the occurrence of leakage at the point of interest listed as data in the region is suppressed. On the other hand, the attention points selected in the sub-regions A1 to A4 and the like are effective for locally recognizing the existence thereof in the range where the (Y) vehicle travels, and the number thereof is large. For this reason, in order to suppress overlapping of the attention points between the sub-regions, in FIG. 5, it is set so that there is no overlapping portion between the adjacent sub-regions.

  As described above, the contents of the items (1) to (3) and (11) to (14) set as the point of interest (the first layer point of interest, the second layer of point of interest) can be set as appropriate. is there. These settings in the first hierarchical area and the second hierarchical area may be appropriately changed according to the purpose or the like.

  In the above example, the first hierarchical area (A to D) and the second hierarchical area (A1 to A4, etc.) are set. However, when the display range is wide, the second hierarchical area is similarly set. Further, it is also possible to set a third layer area according to the division of the third layer, set a point of interest (third layer point of interest) in each third layer area, and display the corresponding points in the same manner as described above. Good. Conversely, the setting may be such that a wide area including the first hierarchical areas A to D is an area obtained by dividing a wider area. That is, in the above example, the number of such divisions is two, but the number of such divisions may be three or more.

  In the above example, the above-mentioned route display method is used in a taxi, the above-mentioned point of interest information is stored in the management center 30, and the display is performed in the mobile station. However, the above-described configuration is effective when displaying the traveling route of the vehicle similarly, and other vehicles, for example, buses, transportation vehicles, general passenger vehicles (including those used for sightseeing as described above), emergency vehicles It is also effective in such cases. In such a case, it is possible to store the above-mentioned point-of-interest information in a device on the vehicle side (a car navigation system or the like) without using the above-described management center and execute the same display method. In this case, a method of setting an optimal route using the above-mentioned importance, for example, is effective, in addition to simply displaying the traveling route.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of the components, and that such modifications are also within the scope of the present invention.
