Is checked, and if not, the process returns to S103-02 and waits for the button to be pressed. On the other hand, when the button is pressed, the process proceeds to S103-04, and it is determined whether the input user information is correct. If it is correct, the process returns to S103-02. If it is correct, the user information is stored in the memory, and the process transits to S103-05 to end this processing routine. Whether the input of the user information is correct or not is determined by whether the necessary input items are input as specified.

FIG. 7 is an example of a user information registration screen for registering the user information used in FIG.

In the case of FIG. 7, the setting items (A3-
01-02) includes items of car, bicycle, and walking, and allows the user to select one of the items, and sets the qualification condition (A3
-01-03) includes items such as employees, customers, and entrepreneurs, and allows multiple selections. Walking restriction setting items (A3-01-04) include healthy persons, elderly persons, and wheelchairs. And have the user select one of them.

FIG. 8 is an example of the user information registered in the process of FIG.

The user information (A3-01) includes the road type information (A3-01-01) and the transportation means (A3-01-0).
2), facility use status (A3-01-03), and walking restriction (A3-01-04). Here, the road type information (A3-01-01) includes the flat road (A3-01).
-01-01), steep slope (A3-01-01-02), stairs (A3-01-01-03), side slope (A3-01-
01-04), elevator (A3-01-01-0)
5) and the step (A3-01-01-06). Flat road (A3-01-01-01)
Take a value such as 2 km / h, and a steep hill cannot pass (NG). For the means of transportation (A3-01-02), values such as car, bicycle, and walking are taken. The facility use status (A3-01-03) takes a value such as an employee (employee of company XX), a customer (customer of company YY), and an in-and-out company (temporary employee from company ZZ). Walking constraint (A3-01-
04) takes values such as a healthy person, an elderly person, and a wheelchair. Further, the walking constraint (A3-01-04) and the road type information (A3-01-01) have a one-way dependency relationship in which the road type information is determined if the walking constraint is determined. For example, when the walking constraint is a wheelchair, a flat road = 2 km / h,
Stairs = not possible, steps = not possible, side slope = not possible, steep slopes = not possible,
The elevator can be set to 2 km / h. Note that the user information (A3-01) corresponds to the user condition information in the memory 103 shown in FIG.

Next, a route guidance operation necessary for executing the route guidance service will be described.

FIG. 9 is a flowchart of a process for executing a route guidance search operation required for executing the route guidance service in S107 of the flowchart shown in FIG.

In step S107-01, the user performs a route guidance request operation using the user terminal 1, activates an application for a target service in the terminal device, and starts processing.

In S107-02, a list of destinations for route guidance (map information, for example, the map information shown in FIG. 10)
Is determined from the server 3 already. If it has already been received, the flow shifts to S107-07. On the other hand, if the destination list has not been received yet, S107-0.
3 in step S107-03, a request for a destination list is sent to the server 3 through the communication unit 104, and the information receiving / sending terminal 2 of the Ir station (information station) 2
Send to 1. At this time, the information receiving / transmitting terminal 21 performs S107-
04, the destination list request is received and transmitted to the PICS server 3. The PICS server 3 creates a destination list in S107-05, and transmits the created list to the communication unit 3.
04 through Ir station (information station) 2
Is transmitted to the user terminal 1 via the information receiving / transmitting terminal 21.
The user terminal 1 side receives the PICS server 3 in S107-06.
Is received (actually, as described above, the map information around the destination shown in FIG. 10).

At S107-07, the departure place, destination, and pedestrian transportation means (car, bicycle, walking, etc.) which are user information, facility use status (employee, customer, entrance / exitant, etc.), walking Restrictions (healthy, elderly, wheelchairs, etc.)
Is set as a search condition.

Here, among the above setting conditions, the user information is the information set by the user in FIG. The departure point for the route search is an Ir station (information station) 2
And the destination is displayed on the display unit 102 / operation unit 105 of the user terminal 1 as the destination list.
Let the user specify the location.

Here, the departure place is designated by the installation position of the Ir station (information station) 2, but the user terminal 1 has a GPS (Global Positioning).
System), a departure place may be acquired by GPS, or a map may be displayed on the display unit 102 of the user terminal 1 to allow the user to specify the departure place.

The destination is specified by displaying a facility list on the display unit 102 of the user terminal 1 and allowing the user to select the destination. However, a map is displayed on the display unit 102 and the destination mark is displayed on the map. May be displayed in a superimposed manner, and the user may touch the destination mark to specify the destination.

FIG. 11 is a diagram showing a state in which a departure place or a destination is specified using the pen as described above.
In this case, the position where the (information station) 2 closest to the designated place is installed may be set as the departure place for route search. Some selection conditions also include items that are automatically selected based on personal information stored in the user terminal 1 and registered by the user. The means for determining the starting point of the route search (determining means) and the means for instructing the destination point (instructing means) have been described above.

In step S107-08, the selection result of the search condition set by the above method is sent to the server 3 via the communication unit 104 as a search request to the server 3. In this case, the destination information itself can be sent instead of the destination ID as a search argument.

In step S107-09, the server 3 receives the route search request sent from the user terminal 1 using the departure point, destination, and user information as arguments.

In S107-10, a relevant item is searched from the destination information list using the search argument as a key. S
In 107-11, it is determined whether or not there is a destination corresponding to the destination information list. In S107-11, if there is a corresponding destination, the process proceeds to S107-12, and if not, the process proceeds to S107-15.

First, if there is a corresponding destination, S10
In step 7-12, available entrance information is searched from the destination information data using the user information as a key. The processing of this part is the core part of the present invention, and will be described later in detail with reference to FIG.

Next, in S107-13, a route search is executed with each entrance as a destination. The route search engine 306 used for this route search usually has a function of selecting a different route by giving a road type such as a general road, an expressway, or a one-way road as a condition. Flat roads, steep slopes, stairs, side slopes, elevators, steps, and the like can also be specified as road types. The present invention is based on the premise that a route search engine that can specify such information as road type information is used. As a result, for example, when the user is a wheelchair user, it is possible to search for a course that does not go up the stairs, avoids a step, and avoids a lateral slope or a slope. At this time, an expected arrival time is also obtained as a route search result.

At S107-14, at S107-13
The optimal route is adopted as a search result from the plurality of routes searched in. For example, if the estimated arrival time obtained as a result of the route search is other than the use time of the entrance, the corresponding entrance is excluded from the candidates, and the shortest route is adopted.

On the other hand, if there is no corresponding destination, S1
At 07-15, a conventional route search ignoring the user information is executed using the route search engine 306.

Regardless of whether the corresponding destination exists or does not exist, the route search result obtained by the search is used via the information receiving / transmitting terminal 21 of the Ir station (information station) 2 in S107-16. Is transmitted to the user terminal 1.

Thus, in S107-17, the user terminal 1 can receive and obtain the route search result executed by the server 3. In S107-18,
The user terminal 1 outputs and displays the received search result on the operation unit 105 / display unit 102.

Thereafter, in step S107-19, the process of the search operation for the route guidance is terminated.

Next, the case of FIG. 11 will be described as an example.

FIG. 11 shows a building in the map information displayed as described above by using a pen which is a coordinate input means of the user terminal 1, and is integrated with the display unit 102 of the user terminal 1. An operation of designating coordinates of a tablet provided in a structure and designating a building as a destination is described.

In this case, since the building is indicated by the pen, various information such as the departure place, the destination (building), and the user information are transmitted from the user terminal 1 to the server 3 in S107-08. .

On the other hand, the server 3 uses the various information sent from the user terminal 1 as a search key to search for information on the corresponding destination stored in the server 3 and constructs a database thereof. .

FIG. 13 shows an example of a database relating to corresponding destination information in the destination information list stored in the server.

Here, the destination building is called "Isogo Daiichi Building" and its location (location) is "35.2 N latitude."
4.3.973, 139.36.15.83 east longitude "
Usage time is "Monday to Friday 9:00 am to 8:00 pm, closed period is Saturday and Sunday, holidays and New Year holidays (December 29-
(January 3) ", the entrance information is" only the facility use status of the entrance D03 is employee ", and in the case of a bicycle as an additional route, the facility guides the route from the bicycle parking lot to the entrance of the building. In FIG. 13, these pieces of information are stored in XML (extensible Markup Lan).
g.). The destination information list is a list in which a plurality of such destination information are arranged.

Next, a description will be given of a core part of the present invention for retrieving usable entrance information from destination information data using user information as a key.

FIG. 12 is a flowchart showing a procedure for narrowing down the available entrances and exits based on the user information as shown in FIG. 8 when the facility has a plurality of entrances and exits as shown in FIG. Actually, it shows the processing contents in S107-12 of FIG. FIG. 14 is a map showing the periphery of the facility shown in FIG.

Here, the facility shown in FIG.
Has five entrances and exits D01 to D05 as shown in FIG.
Is a "stepway with a step", D02 is a "general doorway", D03 is an "employee-only doorway", and D04
Is a "gateway for vehicle traffic" and D05 is a "gateway for a bicycle parking lot". In the pedestrian information shown in FIG. 8, it is assumed that the transportation means is “walk”, the walking constraint is “wheelchair”, and the facility use status is “customer”. Further, when the walking constraint is “wheelchair”, a flat road = 2 km
/ H, stairs = impossible, steps = impossible, side slope = impossible, steep slope =
Impossible, the following description will be made on the assumption that the walking condition is elevator = 2 km / h. The destination is the above building, but here the starting point to reach it is
The following explanation is given as the position of P03 shown in 4.

In FIG. 12, the narrowing operation of the entrance is started in S107-51. In S107-52, the facility information of the facility serving as the destination (the destination information list shown in FIG. 13) is obtained. Here, the destination facility has five entrances D01 to D05, D01 is a "stepped entrance", D02 is a "general entrance", D03 is an "employee-only entrance", and D04 is "vehicle traffic". And information that D05 is the "doorway of the bicycle parking lot". It is assumed that these entrances exist at the positions on the map shown in FIG.

In S107-53, user information (information shown in FIG. 8) is obtained. In the case of FIG. 8, the user information that the transportation means is “walk”, the facility use status is “customer”, and the walking restriction is “wheelchair” is acquired.

In S107-54, the entrance is narrowed down by the moving means. In the facility of FIG. 13, since the transportation means is “walk” in the information of FIG. 8, the “vehicle entrance” D
04 and “Bicycle parking entrance / exit” D05 are excluded from the candidates. As a result, three locations D01, D02, and D03 remain as entrance candidates.

Next, in S107-55, the entrance is narrowed down by the status of use of the facility. Since the facility use status is “customer” in the information of FIG. 8, the “employee entrance / exit” of D03 is also excluded from candidates. As a result, the entrance is D0
Two locations, 1 and D02, remain as doorway candidates.

Next, in S107-56, the road type is
Because only the "flat road" is possible in the information of "stairs",
Entrance entrances with “steps”, “sideways slopes”, and “steep slopes” are excluded from entry / exit candidates. Therefore, D01 has a "step" and is excluded from the candidates for the entrance. As a result, D0
Only 2 remains as a doorway candidate. In this way, the various types of narrowing down are performed, and the process of doorway selection is terminated in S107-57.

Thereafter, S in the flowchart of FIG.
At 107-13, a route through D02 is searched.
In this case, it is possible to obtain the estimated time of arrival on the route until the vehicle actually reaches D02. In S107-14, if the route other than the use time of the entrance D02 (9:00 am to 8:00 pm) among the routes passing through D02, the corresponding route is excluded from the candidates. That is, a route that passes through the entrance D02 before 9:00 am or after 8:00 pm as a curfew can be excluded from candidates.

As a result, the map shown in FIG. 16 is displayed as the content displayed on the display unit 102 of the user terminal 1. This is the map of FIG. 14, which includes the starting point and the destination,
FIG. 15 is a view in which FIG. 15 showing a route to a facility is superimposed.

FIG. 15 shows S107-54, FIG.
In S107-55 and S107-56, the route information calculated by comparing the facility information in FIG. 13 with the user information in FIG. 8 is compared with the distance position of the original map information (for example, the maps in FIGS. 10 and 14). This is the route display information calculated again.

As described above, the map information and the route information and the use information of the target facility are displayed or printed on the user terminal 1 shown in FIG. 1 or FIG. 2 in accordance with the means of transportation, facility use status, walking restriction, and curfew information. Can be output, so that the user can know detailed route information and user information. Although printing is omitted in the system configuration of the user terminal in FIG. 3, it is shown that when the user terminal 1 is provided with a printout unit, the output is not limited to display. I have.

Further, regarding the facility information, the above description does not include information on time fluctuation. However, depending on the facility, the doorway may change depending on the opening time and closing time, or the doorway may be different on closed days.
