Are connected to the terminal 5 so as to be able to transmit and receive information for receiving the transfer guidance service.

  The main system 1 is a computer system. A computer constituting a computer system is an apparatus that causes an arithmetic processing unit (for example, CPU) to perform arithmetic processing of data in accordance with, for example, a program stored in a storage medium. The main system 1 is a system that provides a transfer guidance service to a user in response to a request from the terminal 5 used by the user. The main system 1 receives condition information including conditions requested by the user from the terminal 5, receives traffic information that is information related to the current traffic condition of the road from the traffic system 4, and operates on the road. Information on transfer guidance using an organization such as a bus is created, and this information is transmitted to the terminal 5 used by the user.

  The networks 2 and 3 are, for example, public lines such as the Internet or dedicated lines. The networks 2 and 3 may be independent networks or a common network.

  The traffic system 4 collects traffic information from the road manager traffic system owned by organizations or traders that manage roads, or the traffic information from the road manager traffic system, and holds traffic information in a lump. A system such as a road information system.

  The traffic system 4 divides and manages roads into sections in order to grasp traffic conditions. The sections are divided by, for example, intersections. The traffic system 4 manages traffic information for each section. The traffic information can be received for each section from the traffic system 4 that manages the section.

  For example, the traffic information includes a section speed and a section required time. The section speed represents the average speed of a vehicle that has recently passed through this section. The section required time represents an average time taken for a recently passed vehicle to pass through this section.

  The terminal 5 is a device used by a user who wants to receive a transfer guidance service to access this system. The terminal 5 is a device owned by the user. The terminal 5 is, for example, a mobile phone, a PDA (Personal Digital Assistant) or a personal computer.

This parameter indicates whether to search for stops up to meters. Thereby, the main system 1 searches for the departure stop or the destination stop from the departure point or the destination point to the radius a.

  The reflection range b can be used effectively even if the current traffic information that can be received from the traffic system 4 is within minutes from the current time to the departure time, even if the traffic status by the traffic information is reflected. This is a parameter that expresses time as a range. Thereby, if the departure time is within b minutes from the current time, the main system 1 obtains a required time reflecting the traffic situation (hereinafter referred to as “predicted required time”).

  With reference to FIG. 3, the operation of the main system 1 according to the present embodiment will be described.

  The main system 1 receives condition information including the departure point and the destination point from the terminal 5 (step S101).

  The main system 1 uses the map DB 31 to search for a departure stop and a destination stop from the departure point and the destination point, respectively (step S102). At this time, the main system 1 searches for a stop based on the search range a stored in the parameter storage unit 22. If there are multiple corresponding stops, search for all of them. Further, the main system 1 stores map information indicating the route between the departure point and the departure stop and the route between the destination point and the destination stop.

  In order to provide information to the user, the main system 1 performs processing for creating bus provision information, which is information on transfer information regarding buses, including the route from the departure stop to the destination stop, and the required time. Provision information creation processing LB1).

  The main system 1 provides the user with the bus provision information created in the bus provision information creation process LB1 and the route from the departure point to the departure stop and from the destination point to the destination stop stored in step S102 as information on transfer guidance. In order to provide, it transmits to the terminal 5 (step S103).

  With reference to FIG. 4, the procedure of the bus provision information creation processing LB1 will be described.

  The main system 1 uses the bus route map DB 32 to search for a route from the departure stop to the destination stop. At this time, if there are a plurality of routes, all routes are searched (step S201).

  The main system 1 uses the bus timetable DB 33 to calculate a standard required time of the searched route (hereinafter referred to as “standard required time”). At this time, if there are a plurality of routes, the standard required time for all routes is calculated (step S202).

  Based on the reflection range b stored in the parameter storage unit 22, the main system 1 determines whether or not to obtain the estimated required time by calculating whether or not the departure time is within b minutes from the current time. (Step S203).

  When the determination result does not determine the estimated required time (that is, when the departure time is not within b minutes from the current time), the main system 1 creates the bus provision information using the standard required time (No in step S203). Step S206).

  When the determination result obtains the estimated required time (that is, when the departure time is within b minutes from the current time), the estimated required time is calculated for each route based on the traffic information received from the traffic system 4 (in step S203). Yes, step S204).

  The main system 1 determines whether or not the estimated required time has been calculated for all routes (step S205).

  If there is a route for which the estimated required time has not yet been calculated, the main system 1 designates the next route and returns the procedure to step S204 (No in step S205, step S207).

  When the main system 1 calculates the predicted required time for all routes, the main system 1 creates the bus provision information using the standard required time and the predicted required time (Yes in step S205, step S206). At this time, the bus providing information creates information in which the standard required time and the predicted required time are written for each route.

  With reference to FIG. 5, the calculation method of the estimated required time for the bus to travel from the departure stop A to the destination stop B will be described. Note that this calculation method calculates the estimated required time in the same manner in the following embodiments.

  From the departure stop A to the destination stop B is divided into section SE1, section SE2,..., Section SEN. The section SE1 includes a departure stop A. Section SEN includes destination stop B.

  Here, the distance from the boundary point between the section SE1 and the adjacent section SE2 to the departure stop A is L1. Similarly, the distance from the boundary point between the section SEN and the adjacent section to the target stop B is LN. A section sandwiched between the section SE1 and the section SEN (hereinafter referred to as “medium section”), for example, the section SE2, for example, assumes that the distance between the sections is L2, and other sections are similarly represented. Therefore, the distance from the departure stop A to the destination stop B can be expressed by equation (1).

L1 + L2 + ... + LN (1)
The information received from the traffic system 4 is that the traffic information of the section 1 is the section speed V1, the section required time T1, the traffic information of the section 2 is the section speed V2, the section required time T2, and the traffic information of the section N is the section speed. It is assumed to be expressed as VN and section required time TN. The traffic information of other sections is also expressed in the same manner.

  The estimated required time for the bus to travel the distance L1 is calculated as L1 / V1. Similarly, the estimated required time for the bus to travel the distance LN is calculated as LN / VN.

  For the estimated required time for the bus to travel in the middle section, the required section time is used as the estimated required time. For example, the estimated required time for the bus to travel in the section SE2 is T2.

  As a result, the estimated required time for the bus to travel from the departure stop A to the destination stop B can be expressed by equation (2).

L1 / V1 + T2 + ... + LN / VN (2)
According to the present embodiment, it is possible to provide a transfer guidance system that can provide transfer guidance with a predicted arrival time on a route from a departure point to a destination point using a bus.

Is searched (step S402). At this time, the main system 1 searches for a stop or a station (hereinafter referred to as “stop” or the like) based on the search range a stored in the parameter storage unit 22. If there are multiple corresponding stops, search for all of them. Further, the main system 1 stores map information indicating a route between the departure point and the departure stop, and a route between the destination point and the destination stop.

Initially, the start point is designated as a departure stop, and the end point is designated as the first transfer stop from the departure stop (step S501).

  The main system 1 determines whether the starting point is a stop (step S502). Therefore, when this step is performed first, it is determined whether or not the departure stop is a stop.

  If the main system 1 determines that the start point is not a stop (that is, if it is determined that the station is a station), the process proceeds to the next step S505 with the next transfer stop or the like as the end point (No in step S502). ).

  When the main system 1 determines that the start point is a stop, the main system 1 performs a traffic jam determination logic for the section from the start point to the end point (Yes in step S502, step S503). If the main system 1 determines that the traffic is congested, the main system 1 sets the flag for the relevant section to 1. If the main system 1 determines that the traffic is not congested, the main system 1 leaves the flag for the relevant section as 0. As a method for determining a traffic jam in the traffic jam determination logic, either the logic of the second embodiment or the third embodiment may be used.

  The main system 1 calculates the estimated required time only for the section in which the flag is set to 1 in step S503 (that is, the section determined to be traffic jam) (step S504).

  When the main system 1 determines that the end point is a destination stop or the like, the main system 1 moves the process to the next step S506 (Yes in step S505). When the end point is not a destination stop or the like, the main system 1 returns the procedure to step S502 to perform processing for the next section (No in step S505, step S507).

  If there is a waypoint combination for which provision information has not yet been created, the main system 1 designates the next waypoint combination and returns the procedure to the waypoint-specific provision information creation processing LK (step S604). No, step S607).

  When the main system 1 creates the provided information based on all the combinations of waypoints (Yes in step S604), the main system 1 sorts the routes in the order of the shortest required time (step S605), and informs the user as information regarding the transfer guidance. In order to provide, it transmits to the terminal 5 (step S606).

  With reference to FIG. 15, the procedure of via-point provided information creation processing LK will be described.

  The route-by-route provided information creation processing LK divides the route from the starting stop to the destination stop, etc., for each waypoint based on the combination of the waypoints, and from the beginning of this break (hereinafter referred to as “start point”) to the end (below). , Referred to as “end point”) as one section, processing for creating provision information for each section is performed, and provision information is created based on the processing result.

  The main system 1 designates the start point and the end point (step S701). At first, the start point is designated as a departure stop and the end point is designated as the first waypoint from the departure stop.

  The main system 1 determines whether the starting point is a stop (step S702).

  When the main system 1 determines that the start point is a stop, the main system 1 performs a process for creating bus provision information for a section from the start point to the end point (bus provision information creation process LB1). The bus provision information creation processing LB1 is the same procedure as FIG. 4 if the “departure and destination stops” in the bus provision information creation processing LB1 in FIG. 4 correspond to “start point and end point”.

  When the main system 1 determines that the start point is a station (not a stop), the main system 1 performs a process for creating train provision information for a section from the start point to the end point (train provision information creation process LD). .

  After performing the bus provision information creation process LB1 or the train provision information creation process LD, the main system 1 determines whether the end point is a destination stop or the like (step S703).

  If the main system 1 determines that the end point is not a destination stop or the like, the procedure returns to step S701 to perform processing for creating provision information for the next section (No in step S703, step S705).

  When the main system 1 determines that the end point is a destination stop or the like, the main system 1 creates provision information based on the waypoint based on the bus provision information and the train provision information (step S704).

  With reference to FIG. 16, the procedure of train provision information creation processing LD will be described.

  The train provision information creation process LD performs a process for creating train provision information for the section from the start point to the end point designated by the via-point provided information creation process LK.

  The main system 1 uses the train route map DB 35 to search for a route from the start point to the end point. At this time, if there are a plurality of routes, all routes are searched (step S801).

  The main system 1 uses the train timetable DB 36 to calculate a standard required time (hereinafter referred to as “standard required time”) of the searched route. At this time, if there are a plurality of routes, the standard required time for all routes is calculated (step S802).

  The main system 1 creates train provision information using the standard required time (step S803).

  According to the present embodiment, it is possible to provide a transfer guidance system that can provide transfer guidance with a predicted arrival time on a route from a departure point to a destination point using a bus and a train. Also, by providing the transfer guide information in which the standard required time and the predicted required time are written together, it is possible to select a route suitable for the situation where the user actually uses the public institution (for example, change of departure time).

  Further, by providing the waypoint DB 37, the processing amount of the arithmetic processing unit can be reduced in route search using buses and trains. Thereby, for example, provision of information to the user can be accelerated, or an apparatus (for example, a computer such as a server) having an arithmetic processing unit can be made cheaper.

  In each embodiment, the predicted required time is calculated based on the section required time and the section speed included in the traffic information, but may be calculated based on other elements included in the traffic information. For example, you may calculate based on a section traffic volume (passage number) and an occupation rate. Various selections can be made according to the environment and situation to which this system is applied.

  In each embodiment, the estimated required time for the departure stop A and the destination stop B is calculated by a method different from that for the middle section, but the present invention is not limited to this. For example, the required time per unit distance is obtained by calculating the required time for the section including the departure stop A and the departure stop B by calculating the quotient of the time required for the section and the distance of the section. And the distance for which the estimated required time is obtained may be calculated and used as the estimated required time. Further, the predicted required time of the middle section may be calculated as a quotient of the section distance and the section speed, and this may be used as the predicted required time. Furthermore, the calculation methods for the section including the departure stop A and the departure stop B and the middle section may be interchanged.

  In each embodiment, various parameters are stored in the parameter storage unit 22, but the present invention is not limited to this. For example, various parameters may be input from the terminal 5 by the user. Thereby, the information according to each user's request | requirement can be provided by increasing the choice of the information to provide.

  In each embodiment, the calculation of the standard required time and the predicted required time is properly used, or both are calculated, but only the predicted required time may be calculated.

  In each embodiment, transfer guidance is provided by adding a route by walking using a map DB to transfer between a station and a station, a station and a station, or a station and a station that are not far from each other. May be. By increasing the number of routes by walking, it is possible to increase the choices of routes from the departure point to the destination point. For example, it is possible to increase and provide options such as routes with low travel expenses.

  In 4th Embodiment and 5th Embodiment, although it demonstrated by the train as a public institution which operate | moves except on a road, it is not restricted to this. In addition, it may be a passenger ship or a passenger plane, or may be other as long as the time and departure / arrival place are predetermined. In addition, any number of these may be used to provide transfer guidance. As a result, it is possible to construct a system that can provide a wide variety of transfer guidance.

  In the fifth embodiment, the waypoints registered in the waypoint DB 37 may not be stored in advance. For example, the bus route map DB 32 and the train route map DB 35 may be automatically updated regardless of the operation of the main system 1. Further, when creating the transfer guidance information to be provided to the user, the information may be updated based on the route search result and the like. In addition, by combining with the fourth embodiment, when a via point corresponding to the via point DB 37 is not stored, processing according to the fourth embodiment is performed, and nothing is stored in the via point DB 37 May perform processing according to the fifth embodiment.

  In the fifth embodiment, the procedure of the bus provision information creation processing LB1 shown in FIG. 4 is adopted as the processing for creating the bus provision information. However, the procedure of the bus provision information creation processing LB2 shown in FIG. 7 is adopted. May be.
