4 is a block diagram showing the configuration of a pedestrian road guidance system according to the present invention, Figure 5 is an exemplary view showing a process of calculating the route coordinates according to the present invention.

As shown in FIG. 4 and FIG. 5, the pedestrian road guidance system according to the present invention detects a user's way guidance request, and provides a user guide 100 and a road guidance service for displaying road guidance information to the user. It includes a pedestrian road guidance server 200.

When the user's road guidance request is input, the user terminal 100 receives the location information of the starting point, the location information of the destination, and the walking ability information of the user and transmits the received information to the pedestrian road guidance server 200.

In addition, the user terminal 100 displays the geographic information and the walking path information transmitted from the pedestrian road guidance server 200 for the road guidance to be exposed to the user, and the user terminal 100 on the geographic information and the walking path. Outputs the current position of.

In addition, the walking ability information of the user input from the user terminal 100 is classified into a general person, a disabled person, an elderly person, and the like, so that the appropriate road guidance information can be provided.

In addition, the user terminal 100 is any one of a desktop computer, a notebook computer, a PDA and a mobile communication terminal, it is more preferably equipped with a GPS communication means (not shown) so as to check the current location information. This allows the user to use the location information to be departed as coordinate information when the user sets the current location as the starting point rather than the starting point.

In addition, the user terminal 100 may move, enlarge, reduce, rotate, and display walking path information transmitted from the pedestrian path guidance server 200.

When the pedestrian road guidance server 200 requests a pedestrian road guidance service from the user terminal 100 connected through either wired or wireless communication, the source information, the destination information, and the user transmitted from the user terminal 100. The optimal walking path according to the walking ability of the user is searched and determined based on the walking ability information of the user, and the determined optimal walking path and geographic information on the optimal walking path are transmitted to the user terminal 100.

The pedestrian path guidance server 200 includes a GIS server unit 210, a path generation unit 220, a pedestrian network database 230, a GIS database 240, and a POI database 250.

The path generation unit 220 may enable a walking path from the starting point to the destination based on the user walking capability information transmitted from the user terminal 100, and the coordinate information provided by the GIS server unit 210, and on the walking path. The pedestrian road facility information is retrieved from the pedestrian network database to generate an optimal walking path.

The process of calculating the optimal walking path detects the point B 510 and the point C 530 connected to the point A when moving from the starting point 500 of the point A to the destination 600 of the Z point, wherein B If point 510 is more suitable for the user's walking ability than point C 530, connect point A and point B 510.

That is, when calculating the optimal walking path, the walking path is calculated according to whether there is an appropriate pedestrian road facility based on the walking ability information of the user.

For example, if a user who can use stairs, an underpass, an overpass, a ramp, and the like among pedestrian road facilities, the point D 511 connected to the point B 510 is an underpass, and the point E 520 is a crosswalk. The point D 511 is determined to be suitable for the user's walking ability condition, the point B 510 and the point D 511 are connected, and the above-described process is repeated to repeat the F point 512 and the H point 513. ), The J point 514, the L point 515, the N point 516, and the Z point, which is the destination 600, are sequentially connected to calculate an optimal first walking path 700 indicated by a solid line.

On the contrary, if a user who is difficult or unable to use stairs, underpass, overpass, ramp, etc. among pedestrian road facilities, point D 511 connected to point B 510 is an underpass, and point E 520 is a crosswalk. In this case, the point E 520 is determined to be suitable for the user's walking ability condition, the point B 510 and the point E 520 are connected, and the above-described process is repeated to repeat the point O 521 and the point I ( 522, the J point 514, the M point 523, the P point 524, and the Z point which is the destination 600 are sequentially connected to calculate an optimal second walking path 710 indicated by a dotted line.

Therefore, the path generation unit 220 generates pedestrian path information by dividing the optimal pedestrian path for each section, and sequentially generates an optimal pedestrian path according to the pedestrian ability information of the user.

On the other hand, the path generation unit 220 generates the optimal walking path by first selecting the shortest path when the walking ability condition of the user is not input or there is no path matching the input walking ability condition.

The pedestrian network database 230 stores pedestrian road facility information including information such as traffic lights, crosswalks, underpasses, overpasses, pedestrian lifts, pedestrian walkways, bicycle roads, downtown roads, back roads, stairways, and ramps.

The GIS database 240 stores geographic information including map image information, scale information, and coordinate information.

In addition, the GIS database 240 further includes a POI database 250 that stores address information and main feature information (POI). When the walking path is set, address information corresponding to the coordinate information of the set walking path and The main feature information (POI) is retrieved from the POI database 250 and provided to the GIS server unit 210.

A pedestrian road guidance process will be described in more detail with reference to FIG. 10.

In the pedestrian road guide method according to the present invention, when the user terminal 100 requests a road guide by accessing a pedestrian road guide server 200 having map information and pedestrian road facility information (S100), the user terminal 100 From the starting point information, the destination information and the user walking ability information is detected (S200, S300 and S400).

Detecting the departure point information (S200) searches for the departure point 500 based on the departure point location information input from the user terminal 100 (S210).

That is, when the starting point 500 determines whether the current location is the current location (S220) and the current location is input as the starting point from the user terminal 100, the pedestrian road guide server 200 is currently present from the GPS communication means installed in the user terminal 100. Receives the GPS position coordinate information of (S230) to set the starting point (500).

In step S220, when the starting point 500 is an arbitrary location, the pedestrian road guidance server 200 receives starting point information input from the user terminal 100 and starts from the GIS database 240 and the POI database 250. Search for the address and the main POI information, etc. (S231).

The pedestrian route guidance server 200 detects the X, Y coordinate information, the scale information, and the map image information of the departure point based on the departure point information detected in step S230 or S231 (S240) and provides it to the user terminal 100. In operation S250, it is determined whether setting completion information is input from the user terminal 100 to determine whether to terminate or re-search for departure information.

Searching for the destination information (S300) receives location information, POI information, etc. for any destination 600 input from the user terminal 100 (S310), and the pedestrian road guidance server 200 receives the user terminal ( X, Y coordinate information, scale information, and map image information of the destination 600 are detected from the GIS database 240 and the POI database 250 based on the place name information or the POI information of the destination inputted from 100 (S320 and S330). In step S340, it is determined whether the setting completion information is input from the user terminal 100, and whether to terminate or re-search for destination information is determined.

Searching for the user's walking ability information (S400) is a case where the pedestrian road guidance server 200 is guided by the general public from the user terminal 100, a case where a disabled person and an elderly person are guided, and an exercise path. And the difficulty according to the user's walking ability, such as when the user is guided to the shortest path regardless of the user's walking ability (S410), and the road facilities available to the user according to the walking ability of the user input in step S410. Information is detected (S420).

In other words, if the user is not inconvenient to use general pedestrian road facilities in step S420, pedestrian road facilities such as stairs, viaducts, underpasses, and ramps are applied, and pedestrian-only roads, pedestrian crossings, non-sloped roads, etc. This should apply.

In addition, in step S420, if the disabled or the elderly are pedestrian road facilities such as pedestrian-only roads, crosswalks, non-slope roads, pedestrian lifts to be applied first.

In addition, in the case of requesting the exercise path in step S420, pedestrian road facilities such as pedestrian roads, bicycle roads, crosswalks, etc. may be applied according to exercise characteristics (eg, walking, jogging, bicycle use, inline skating, etc.).

In addition, regardless of the difference in the ability of walking, it is also possible to be able to detect information on the road facilities, such as pedestrian safety, such as overpass, underpass, elevator.

The pedestrian route guidance server 200 is a possible pedestrian path from the source 500 to the destination 600 in the GIS database 240 based on the input source 500, the destination 600, and the user walking ability information. The optimal pedestrian path including coordinate information is generated using the road facility information on the pedestrian path from the pedestrian network database 230 in which geographic information including map image information, scale information, coordinate information, and pedestrian road facility information is stored. (S500).

The step S500 may further include determining whether a rescanning request for a route is input from the user terminal 100 during generation of the walking route (S510), and whether an additional search request for the route is input (S520). When there is a re-search or additional search request of the walking path, the step S200 is performed again. When there is no re-search or additional search request of the walking path, the generated path is transmitted to the user terminal 100 so that the walking path is displayed (S530). ) do.

In addition, the optimal walking path generated in step S500 is divided into sections to generate walking path information, and the path is sequentially generated according to the walking ability information of the user.

In addition, the POI database 250 retrieves the address and the main feature information corresponding to the coordinate information of the generated optimal walking path as well as the geographic information to provide the user terminal 100 to guide the walking path (S600). .

11 is a diagram illustrating a walking path when the user's walking ability information is input to the general person. When the starting point 500 information, the destination 600 information, and the user's walking ability information (the general person) are input, the pedestrian path The guide server 200 searches for the shortest path and the optimum path using the departure point 500, the arrival point 600, and road facilities available to the public, ie, pedestrian roads, underpasses, overpasses, and the like, to the user terminal 100. 1 provides a map image 800 to which the walking path 700 is applied.

Pedestrian facilities information is also displayed.

In the case of guiding from the departure point 500 to the arrival point 600, the movement route from the departure point 500 to the first waypoint 510 (B point in FIG. 5) is guided. At this time, the entrance number of the underpass is output so that the underpass can be used.

The exit number of the underpass is output so that the user can move to the second waypoint 511 (point D of FIG. 5) by using the underpass, and the third waypoint 512 (point F of FIG. 5), which is the next route, is displayed.

That is, according to the walking ability of the user to guide the shortest, optimal walking path using the underground road and pedestrian road.

12 is a diagram illustrating a walking path when the user's walking ability information is input as a disabled person. When the starting point 500 information, the destination 600 information, and the user's walking ability information (handicapped person) are input, the pedestrian path The guide server 200 searches for the shortest route and the optimal route using the departure point 500, the arrival point 600, and road facilities available for the disabled, such as a pedestrian road, a pedestrian crossing, a non-inclined path, and the like. The map image 800 to which the 700 is applied is provided to the user terminal 100.
