[Information provision system processing]
Next, an example of the processing of the information providing system in the first embodiment configured as described above will be described below with reference to FIGS. FIG. 2 is a flowchart illustrating an example of processing of the information providing system according to the first embodiment.

  As shown in FIG. 2, first, the position information transmission unit 102b of the terminal device 100 causes the display unit 114 to display an input screen for inputting a route search condition including conditions regarding the departure point, the destination, and the walking use. When the route search condition is input by the user via the input unit 118, the route search condition and the position information are transmitted to the information providing server 200 (step SA-1). Here, the position information is the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a, or position information (for example, an arbitrary point input by the user via the input unit 118). , Point information corresponding to the position tapped on the displayed map information). For example, the position information transmission unit 102b displays an input screen including map information on the display unit 114, and when the map information displayed via the input unit 118 is tapped by the user, the position information transmission unit 102b corresponds to the tapped position. The position information may be acquired and the position information may be transmitted to the information providing server 200. Further, the route search conditions further include a transit point, transportation means (for example, public transportation use, bicycle use, rail use, or car use), departure time, via time, arrival time, and / or date. The conditions regarding may be included.

  Then, the reference position information acquisition unit 202a of the information providing server 200 receives the route search condition and the position information transmitted from the terminal device 100 (Step SA-2).

  Then, the reference position information acquisition unit 202a of the information providing server 200 acquires the position information received in Step SA-2 as reference position information regarding the reference position (Step SA-3). Here, when the walking route satisfying the route search condition received by the reference position information acquisition unit 202a is searched by the route searching unit 202e, the reference position is a sidewalk node or a sidewalk link included in the walking route. Also good. Further, the reference position may be a point (position) between the departure point and the destination based on the route search condition received by the reference position information acquisition unit 202a.

  Then, the attention point specifying unit 202b of the information providing server 200 connects the roadway link that intersects the sidewalk link that exists within the predetermined range from the reference position based on the reference position information acquired by the reference position information acquisition unit 202a. Based on the approach direction to the intersecting roadway link, the attention point is specified (step SA-4). As described above, the caution point specifying unit 202b that determines the caution point may acquire a pedestrian crossing around the reference position and determine the crossing situation between the pedestrian crossing and the road link. Specifically, the caution point specifying unit 202b may determine whether the vehicle has entered the vehicle, that is, whether the road link enters a right turn, a left turn, a straight entry, or a vehicle entry prohibition. Moreover, the caution point specific | specification part 202b may determine the approach form of a pedestrian. Further, the attention point specifying unit 202b cannot easily turn right as the amount of traffic on the opposite lane increases, so the number of vehicles trying to make a right turn increases. The presence or absence and / or the size of the intersection may be determined. In consideration of such information, in the present embodiment, the danger level of the pedestrian crossing may be determined, and if there is a danger level equal to or higher than a predetermined value, the caution information may be notified. Here, the caution point specifying unit 202b may exclude the intersection point where the vehicle is unlikely to pass due to traffic restrictions or the like from the target of the caution point, and thus may consider the traffic restriction information. In addition, the attention point specifying unit 202b may have a time zone such as nighttime because the visibility is particularly bad at night and the headlights in the opposite lane are visible when turning right.

  Here, with reference to FIG. 3, an example of details of the attention point specifying process in the present embodiment will be described. FIG. 3 is a flowchart showing an example of details of the attention point specifying process in the present embodiment.

  As shown in FIG. 3, first, the attention point specifying unit 202b is a crossing that is a sidewalk link that intersects a roadway link existing within a predetermined range from the reference position based on the reference position information acquired by the reference position information acquisition unit 202a. A sidewalk is specified (step SB-1). Here, the pedestrian crossing may be a sidewalk link connected to the reference position.

  Then, the cost setting unit 202c includes the presence / absence of a roadway link that is the opposite lane of the roadway link that intersects the walking link including the pedestrian crossing specified by the attention point specifying unit 202b, the traffic volume of the roadway link that is the opposite lane, Obtain road condition information including the size (eg, size) of the roadway node (eg, intersection) to which the roadway link is connected and / or the installation status of traffic lights on the roadway link or the roadway node (step) SB-2).

  And the cost setting part 202c is approached from the roadway link connected to the roadway link which crosses the walk link including the pedestrian crossing based on the road condition information acquired in step SB-2. Based on the above, the cost (risk level) of the walking link including the pedestrian crossing is set (calculated) (step SB-3). Here, in the cost setting unit 202c, the approach direction from the roadway link connecting to the roadway link intersecting with the walking link including the pedestrian crossing is the straight line approach, the left turn approach, or the right turn approach. Based on this, the cost (risk level) of the walking link including the pedestrian crossing may be set (calculated). In addition, the cost setting unit 202c further sets the opposite lane of the roadway link when the approach direction from the roadway link connected to the roadway link intersecting with the walk link including the pedestrian crossing is a right turn approach. Crossing based on road condition information including the presence or absence of a roadway link, the traffic volume of the roadway link that is the opposite lane, the size of the roadway node to which the roadway link is connected, and / or the traffic light installation status on the roadway link or roadway node The cost (risk level) of the walking link including the sidewalk may be set (calculated).

  And the caution point specific | specification part 202b specifies the walk link containing the crosswalk whose risk calculated by the cost setting part 202c in step SB-3 is more than predetermined value as an caution point (attention point). Step SB-4), the attention point specifying process is terminated.

  Here, with reference to FIG. 4 thru | or FIG. 6, an example of the caution point (caution point determination location) in this embodiment is demonstrated. 4 to 6 are diagrams illustrating examples of attention points in the present embodiment.

  As shown in FIG. 4 and FIG. 5, when the reference position is the current position (user position), the caution point specifying unit 202b links the road from the right turn car approach path for the pedestrian crossing near the current location (peripheral pedestrian crossing). May cross the pedestrian crossing, it may be specified as a caution point to be notified of the caution information.

  As shown in FIG. 6, when a predetermined point (sidewalk link or sidewalk node) on the walking route is a reference point, the intersection with the roadway link (road link) at the predetermined point of the sidewalk link (walking link) It is possible to determine and provide an alert point on the walking route in the same manner as the guide point so that it can be properly guided at the time of route guidance.

  An example of cost setting in the present embodiment will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of cost setting in the present embodiment.

  As shown in FIG. 7, the cost setting may be performed at the time of route search. When searching for a walking route using a pedestrian network (walking network), the cost is set in an intersection with the vehicle network (road network). The link cost may be increased or decreased according to the risk level calculated accordingly. In the schematic diagram of the caution point determination location in the present embodiment shown in FIG. 7, only the influence on the walking network of the road link (road link) entering from the illustrated entrance link with respect to the intersection is illustrated for simple explanation. May be extracted. At the time of actual route search, the approach link from other directions may be calculated in the same manner for the walking network. Here, as shown in FIG. 7, at the time of route search, since the link La intersects with the left turn approach link of the road network, the cost of the link La may be increased from the link cost without the intersection with the road network. On the other hand, since the links Lb and Lc intersect with the link of the road network that goes straight ahead, this may also be increased from the link cost without the intersection with the road network. Further, the increase in the link cost between the left turn approach link and the straight approach link may be set in more detail according to the situation of the intersection and the link attribute. Specifically, the degree of influence on the link cost may be changed depending on whether the intersection is large or small. In addition, in the case of a pedestrian separation type signal such as a scrambled intersection where the traffic lights can pass only to pedestrians (green light) and all the vehicles become stop signals (red light) as the situation of the intersection, the cost should be reduced It may be. Furthermore, the cost of a sidewalk link (pedestrian link) may be increased at an intersection where a left turn enable display board is displayed with respect to a vehicle that turns left. Moreover, as shown in FIG. 7, when crossing the right turn approach link like the link Ld, the link cost may be increased most. In this case as well, more detailed settings may be made according to the traffic light conditions. For example, when a right turn approach is made only when a pedestrian's stop signal (red light) is present, the link cost does not need to be significantly increased because there is no influence from the entry of a right turn vehicle. Furthermore, when the intersection is large, there is a position where the vehicle stops at the pedestrian crossing, so a difference may be made between the small intersection and the link cost. On the other hand, at an intersection where a right turn vehicle needs to sew between the vehicles on the opposite lane and make a right turn, the cost of the pedestrian link may be increased or decreased in consideration of the traffic on the opposite lane.

  Returning to FIG. 2, the attention information generation unit 202d of the information providing server 200 generates attention information regarding the attention point specified by the attention point specification unit 202b (step SA-5). Here, the attention information may be display information (character information, image information, etc.) and / or audio information that alerts the user.

  Then, the route searching unit 202e of the information providing server 200 obtains reference position information based on the cost (risk level) set (calculated) by the cost setting unit 202c and the traffic information stored in the traffic information database 206b. The walking route, which is a guidance route by walking from the starting point to the destination, that satisfies the route search condition received by the unit 202a is searched using the network information for pedestrians stored in the network information database 206a, and the walking route The walking route information that is the route information is generated (step SA-6). Here, the route search unit 202e, from the roadway link connected to the roadway link intersecting with the sidewalk link connected to the reference position, from the departure point to the destination when the approach direction to the intersecting roadway link is a right turn approach May be searched using the pedestrian network information excluding the sidewalk link information related to the sidewalk link intersecting with the roadway link stored in the network information database 206a to generate the walking route information. In addition, when the route search condition includes a condition regarding a waypoint, the route search unit 202e may search for a guide route that passes through the route point.

  Here, an example of a walking route (effective walking route) output in the present embodiment will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of a walking route in the present embodiment.

  FIG. 8 shows an example of a walking route (effective walking route) selected in accordance with the set link cost when there are a plurality of walking routes that satisfy the route search condition. As shown in FIG. 8, as an output pedestrian route, a walking route (invalid walking route) passing through a pedestrian crossing (unusable pedestrian crossing) near an intersection is not selected, and a roadway link ( A walking route (effective walking route) set to cross the road) may be selected and provided.

  Returning to FIG. 2, the output information transmission unit 202f of the information providing server 200 is stored in the attention information generated by the attention information generation unit 202d, the walking route information generated by the route search unit 202e, and the map information database 206c. The map information related to the map including the walking route is transmitted to the terminal device 100 (step SA-7). Here, the output information may further include guidance information (display guidance information, voice guidance information, etc.) stored on the guidance information database 206d and output on the walking route.

  Then, the output information receiving unit 102c of the terminal device 100 receives the output information transmitted from the information providing server 200, and stores the received output information in the output information file 106a (step SA-8).

  And the output information output part 102d of the terminal device 100 displays the output information memorize | stored in the output information file 106a on the display part 114 (step SA-9), and complete | finishes a process. When the user inputs a route guidance start request for the walking route via the input unit 118, the output information output unit 102d stores the output information file 106a on the map information stored in the output information file 106a. The route guidance may be executed by superimposing the displayed walking route information and the current location information of the user of the terminal device 100 acquired by the current location information acquisition unit 102a on the display unit 114. Here, the output information output unit 102d may cause the display unit 114 to display display guidance information corresponding to the walking route stored in the output information file 106a. Further, the output information output unit 102d may output voice information corresponding to the display (voice guidance information stored in the output information file 106a) via the voice output unit 116.
