Description

Congestion monitoring device, congestion monitoring method, and congestion monitoring program

The present invention relates to a technique for providing information related to a congestion state in a predetermined monitoring target range such as a railway station.

時 Passenger traffic at railway stations is a problem especially in metropolitan areas such as when commuting. Congestion at the railway station can lead to the danger of passengers falling from the platform, and delays in train operation due to increased time required for passengers to get on and off the railway train due to congestion. In order to alleviate congestion or reduce the influence of congestion, it is required to grasp or predict the congestion situation and notify the passenger or operator of the congestion situation.

Several methods have been disclosed so far to grasp the congestion of railway stations. Patent Document 1 discloses a technique for measuring passenger movement with a monitoring camera or an automatic ticket gate and calculating the degree of congestion for each area in a railway station in real time using the obtained passenger movement data and pedestrian simulation. Is disclosed.

JP 2008-217289 A

The reason for notifying passengers and operators of the congestion situation is to determine the necessity of countermeasures for congestion such as entrance restrictions to the station premises or guidance of detour walking, and to determine appropriate countermeasures for congestion. However, just because the degree of congestion is high, it does not necessarily mean that the situation should be notified to passengers or operators. This is because the degree of congestion at the railway station varies greatly depending on the time zone and area even in a normal state without any abnormality. For example, if it is an area where daily congestion occurs in the morning and evening commuting hours, the significance of notifying passengers and operators of the morning and evening congestion in that area is not high. For this reason, it may not always be appropriate to determine the necessity of notification by determining the threshold of congestion.

An object of the present invention is to provide a technique for appropriately determining whether the congestion state in the monitoring target range is normal or abnormal.

A congestion monitoring device according to an embodiment of the present invention is a congestion monitoring device that monitors passenger congestion in a monitoring target range, and indicates the degree of congestion for each time zone for each area obtained by dividing the monitoring target range. A congestion estimation unit that estimates an index, a congestion index management unit that holds a standard value of the congestion index for each time zone for each area, and a congestion index comparison unit that generates increase / decrease information indicating increase / decrease of the congestion index with respect to the standard value And an output unit that outputs notification information corresponding to the increase / decrease information.

According to the present invention, the congestion index for each area and each time zone is compared with the standard value for each area and each time zone, and the notification information corresponding to the increase / decrease with respect to the standard value of the congestion index is output. It is possible to appropriately determine whether the congestion situation is normal or abnormal.

Embodiments of the present invention will be described with reference to the drawings.

<Overview>
FIG. 1 is a block diagram of the congestion monitoring apparatus according to the present embodiment. The congestion monitoring device 100 divides the monitoring target range into a plurality of areas and monitors passenger congestion in each area. The congestion monitoring apparatus 100 includes a congestion estimation unit 101, a congestion index management unit 102, a spatial information management unit 105, a congestion index comparison unit 103, a guidance route calculation unit 104, and an output unit 106.

The congestion estimation unit 101 estimates a congestion index representing the degree of congestion for each area in real time, and outputs it as congestion index information.

The congestion index management unit 102 accumulates the congestion index information in the database and calculates and records the statistical information of the congestion index. For example, statistical information such as an average value or a median value in a predetermined period in the past is used as a standard value (standard value) of a congestion index particularly in a normal state in which no abnormality related to the area has occurred.

The spatial information management unit 105 holds, for each area, spatial information representing the position, the connection relationship in which passengers can move between the areas, and the time required to pass through the area.

The congestion index comparison unit 103 notifies the passenger or the station staff of the congestion index based on the congestion index statistical information recorded in the congestion index management unit 102 and the congestion index for each area output from the congestion estimation unit 101. To decide.

The guidance route calculation unit 104 calculates a guidance route for guiding the passenger so as not to pass through an area where the degree of congestion is higher than the standard state based on the comparison result in the congestion index comparison unit 103. When calculating the guidance route, the guidance route calculation unit 104 refers to the spatial information recorded in the spatial information management unit 105, and the time required to pass through the area and the connection relationship between the mutually movable areas. To figure out.

The output unit 106 outputs the notification information from the congestion index comparison unit 103 and the guidance route information of the guidance route calculation unit 104.

The information output from the output unit 106 is sent to the information terminal 107 for use by the passenger or station staff, and the information is notified to the passenger or station staff by screen display or voice output.

Hereinafter, the operation of each part and the mutual relationship will be further described.

The congestion estimation unit 101 estimates a congestion index indicating the degree of congestion for each time zone for each area obtained by dividing the monitoring target range. The congestion index management unit 102 holds a standard value of the congestion index for each time zone for each area. The congestion index comparison unit 103 generates increase / decrease information indicating an increase / decrease with respect to the standard value of the congestion index. The output unit 106 outputs notification information corresponding to the increase / decrease information. According to this, the congestion index for each area and each time zone is compared with the standard value for each area and each time zone, and the notification information corresponding to the increase / decrease with respect to the standard value of the congestion index is output. It is possible to appropriately determine whether the congestion state is normal or abnormal.

Note that the congestion index management unit 102 accumulates the congestion index for each area and each time zone calculated by the congestion estimation unit 101, and performs statistical processing on the accumulated congestion index, so that each area and each time zone The standard value of is calculated. Since the standard value is calculated by statistical processing on the congestion index actually measured in the past and the current congestion index is compared with the standard value, how much the current congestion index has increased or decreased compared to the past standard state It can be used for notification of the status.

Further, the congestion index management unit 102 further holds an increase / decrease threshold that is a predetermined threshold for the increase / decrease information. Then, the congestion index comparison unit 103 compares the increase / decrease information and the increase / decrease threshold for each area for each time period. The guide route calculation unit 104 calculates a guide route that is a travel route that does not pass through an area where the increase / decrease information exceeds the increase / decrease threshold. The output unit 106 outputs the guidance route. Although there is a possibility that an abnormality has occurred in an area where the degree of congestion is higher than normal, this configuration can guide the passenger to avoid such an area.

In addition, the output unit 106 displays the monitoring target range and each area inside it in a map format, and displays each area differently according to the increase / decrease information on the map. As a result, the comparison result between the congestion index and the congestion index standard value can be visually represented on the map, so that it is possible to visually grasp the area where the degree of congestion is higher than usual.

In addition, the output unit 106 displays each area in a different color according to the increase / decrease information. As a result, the comparison result between the congestion index and the standard value is displayed in a color-coded manner on the map, so that the area where the degree of congestion is higher than normal can be easily grasped by distinguishing the colors.

Also, the congestion index management unit 102 may hold a plurality of increase / decrease threshold values for each time zone for each area. In that case, the congestion index comparison unit 103 compares the increase / decrease information for each area and each time zone with a plurality of increase / decrease thresholds. Based on the comparison result between the increase / decrease information for each area and each time zone and a plurality of increase / decrease thresholds, the output unit 106 assigns a plurality of levels of congestion increase / decrease to each area, and displays the congestion increase / decrease of each area. According to this, since the degree of increase / decrease with respect to the standard value of the congestion index for each area is output in a plurality of stages, it is possible to grasp how much the degree of congestion is higher than usual for each area.

Also, the output unit 106 sorts each area according to increase / decrease of the congestion index with respect to the standard value, and outputs the sorting result. As a result, the areas are displayed in the descending order of the degree of increase in the degree of congestion from the normal level, so that it is possible to grasp where the area with high priority for implementing the congestion improvement measure is.

It should be noted that the time zone referred to here may not only distinguish the time zone within a day, but may further distinguish the day type such as a difference in day of the week or a weekday holiday. Since the state of congestion at normal times differs depending on the day of the week and the type of day, by distinguishing those days, areas in a different congestion state from normal times can be detected with higher accuracy.

In addition, the congestion index comparison unit 103 further compares the congestion index for each area and each time zone with a common congestion threshold that is a common threshold for the area and the time zone for the congestion index,

The output unit 106 may output predetermined notification information for an area where the increase / decrease information exceeds the increase / decrease threshold and the congestion index exceeds both the common congestion threshold. According to this, it is possible to grasp the area where both the congestion index itself and the degree of increase are high.

In addition, the guidance route calculation unit 104 includes a normal time required for passing through each area during normal times and an abnormal time required for passing when the increase / decrease information exceeds the increase / decrease threshold. Is set as a guide route when there is a route that requires less time to travel than a normal route that is assumed during normal operation as a travel route between two areas. May be. According to this, it is possible to guide the passenger to a guide route that can pass through an area where the increase in the congestion index is large and that can pass in a shorter time than the normal route.

Hereinafter, this embodiment will be described in more detail.

<Explanation of data>
FIG. 2 is a table showing an example of the congestion index accumulated in the congestion index management unit. In the congestion index information 200a shown in FIG. 2, the area column 201a indicates each area, and the time zone column 202a indicates a time representative of the target time zone. For example, “20%” of the congestion index 203a indicates that the congestion index at position A401 at time 9:00 is 20%. Here, the congestion index is expressed as a ratio of the congestion degree expressed by the number of passengers per area to a predetermined congestion degree corresponding to 100%.

It should be noted that the time zone column 202a may be represented not by time but by a period so that the congestion index for a certain period is a predetermined value.

Further, for example, the congestion estimation unit 101 outputs a congestion index at the calculated target time, and the congestion index management unit 102 sequentially adds the congestion index to the database in the format shown in FIG. Also good. Alternatively, the congestion estimation unit 101 may output the congestion index information in the format shown in FIG. 2, and the congestion index management unit 102 may record the received congestion index information in a database.

FIG. 3 is a table showing an example of standard values of the congestion index calculated by the congestion index management unit. The standard value in FIG. 3 may be in the same format as the congestion index in FIG. For example, an average value in a past predetermined period may be registered in the table of FIG. 3 as a standard value used by the congestion index comparison unit 103. In the congestion index information 200b shown in FIG. 3, the area column 201b indicates each area, and the time zone column 202b indicates a time representative of the target time zone. For example, “15%” of the standard value 203b of the congestion index indicates that the standard value of the congestion index at the position A401 at time 9:00 is 15%.

FIG. 4 is a table showing an example of increase / decrease information indicating increase / decrease with respect to the standard value of the congestion index. In the increase / decrease information 300, an area column 301 indicates each area, and a time zone column 302 indicates a time representative of the target time zone. For example, “+ 5%” in the increase / decrease information 303 indicates that the increase / decrease with respect to the standard value 203b of the congestion index 203a detected in real time at the position 401 at time 9:00 is an increase of + 5%. The increase / decrease information is a congestion index of the statistical information and an increase / decrease ratio with respect to the statistical information of the congestion index detected in real time. Or it is good also as a difference for every area.

FIG. 5 is a table showing an example of a result of determining whether or not the congestion state of each area is within the normal range based on the increase / decrease information of the congestion index shown in FIG. Here, if the congestion index is within a range of ± 20% of the standard value, it is determined as normal. That is, it is normal if the increase / decrease information is within a range of ± 20%.

For example, “normal” in the determination result 503 indicates that the area at the position A401 (501) at time 9:00 (502) is determined to be in a normal congestion situation. “Abnormal” in the determination result 504 indicates that it is determined that the area at the position A404 (505) at time 9:00 (502) is in an abnormal congestion state.

FIG. 6 is a diagram showing an example of position information of each area of the monitoring target range included in the spatial information as a map. Position A404 is the area around the ticket gate, positions A405 and A413 are the concourse area after entering the ticket gate, positions A406 and A410 are the stairs area, positions A407, A408, A409, A411, and A412 are the platform area, position A401, A402, A403, and A414 indicate areas outside the ticket gates of the station, respectively.

FIG. 7 is a table showing an example of information indicating connection and movement time between areas in the monitoring target range included in the spatial information. In the information 600 shown in FIG. 7, for example, “5 seconds” in 603 indicates that the area A401 shown in 602 is connected to the area A402 shown in 601 and the moving time between them is 5 seconds. “-” In 605 indicates that it is not possible to move directly from the area A 401 indicated by 602 to the area A 403 indicated by 604 without passing through another area.

FIG. 8 is a diagram showing an example of connection information between areas in the monitoring target range included in the spatial information on a map network. Vertex nodes N401 to N414 respectively corresponding to the areas from the position A401 to the position A414 are set. The connection between the vertex nodes is set to match the information 600 between the areas. This means that a passenger can move between two nodes connected by the side.

<Details of each part>
The congestion estimation unit 101 will be described.

In each area, sensors are installed so that people passing through the boundary of the area, that is, the entrance and exit can be observed. The congestion estimation unit 101 sets each area as an observation target, and measures the number of inflows and outflows observed by a sensor at the entrance and exit of the area to be observed. The congestion estimation unit 101 holds area area information indicating the area of each area in advance, and passengers in each area based on the information on the number of inflows and / or outflows at the entrance / exit of the area and the area area information. The density of is calculated. The density of passengers in each area is used as a congestion index.

As another example, when it is not possible to observe people who pass through the boundaries of all areas, the congestion estimation unit 101 obtains the density of passengers in each area included in the observable space where people can be observed. The estimated value may be used as a congestion index for each area. In that case, the congestion estimation unit 101 measures the number of inflows and outflows at the entrance / exit which is the boundary of the observable space. The congestion estimation unit 101 holds branch information indicating a branching rate indicating a ratio of the destination outlet and outlet for each doorway in the observable space, and based on the number of inflows and the branch information, the observable space The flow of people in each area is estimated, and the density of passengers in each area is calculated. In addition, the congestion estimation unit 101 estimates the number of outflows at each doorway based on the number of inflows in the observable space and the branch information. Then, the congestion estimation unit 101 compares the estimated number of outflows with the measured number of outflows, evaluates the estimation accuracy based on the comparison result, and updates the branch information.

FIG. 9 is a block diagram illustrating a configuration example of the congestion estimation unit according to the other example. The congestion estimation unit 101 includes a person counting unit 1011, a recording unit 1012, a movement estimation unit 1013, an evaluation unit 1014, and a congestion index calculation unit 1015.

The number-of-people measuring unit 1101 uses the observable space as a target space, and uses the boundary connecting the target space outside the target space as an entrance / exit, and measures the number of people flowing into and out of the target space at the entrance / exit.

The recording unit 1102 includes inflow information indicating the number of people passing in the direction of flowing into the target space from the entrance, outflow information indicating the number of people passing in the direction of flowing out of the target space from the entrance, the target space, its entrance and exit, and the entrance Corresponding to the estimation result, target space information including travel time information indicating the time required for travel between, branch information indicating the branch rate indicating the ratio of the destination outlet for each entrance in the target space, and Record the evaluation result information indicating the result of the validity evaluation of the estimation.

The movement estimation unit 1013 receives the measured inflow information, space information, and branch information as input, estimates OD information representing movement between the entrances and exits, and estimates the movement of people between the entrances and exits.

The evaluation unit 1014 compares the outflow number information estimated by the movement estimation unit 1103 with the outflow number information acquired from the recording unit 1012, evaluates the validity of the estimation processing by the movement estimation unit 1013 based on the comparison result, The sex evaluation result and the estimation result are output to the recording unit 1012 and the branch information is updated.

The congestion index calculation unit 1015 calculates a congestion index of each area designated in advance in the target space based on the estimation result of the movement of the person between the entrance and exit of the movement estimation unit 1013. For example, the congestion index calculation unit 1015 calculates, for each area, the average number of visitors per area and the number of people passing by per unit time, and outputs these as the area congestion index.

For example, in the estimation process in the movement estimation unit 1013, the position information of the pedestrian agent is sequentially updated based on the OD information. Then, the congestion index calculation unit 1015 calculates the average number of staying people per area and the number of passing people per unit time for each area specified in advance based on the position information of the pedestrian agent.

This completes the description of the congestion estimation unit 101.

Next, the congestion index comparison unit 103 will be described.

FIG. 10 is a flowchart showing the processing of the congestion index comparison unit. First, in step S <b> 1001, the congestion index comparison unit 103 acquires the congestion index of each area at time t output from the congestion estimation unit 101. Next, the congestion index comparison unit 103 acquires a standard value corresponding to the congestion index acquired in step S1001 from the congestion index management unit 102 in step S1002. At this time, the congestion index comparison unit 103 may acquire the standard value of the congestion index in each area in the time zone including the time t or the time t.

Further, in step S1003, the congestion index comparison unit 103 compares the congestion index acquired in step S1001 with the standard value of the congestion index acquired in step S1002, and generates increase / decrease information indicating increase / decrease of the congestion index with respect to the standard value. To do. Here, as an example, the increase / decrease information represents the difference between the congestion index and the standard value, but is not limited to this. As another example, the increase rate of the congestion index based on the statistical information may be used as the increase / decrease information. In step S1004, the congestion index comparison unit 103 outputs the congestion information generated in step S1003.

This completes the description of the processing of the congestion index comparison unit 103.

Next, processing of the guidance route calculation unit 104 will be described. FIG. 11 is a flowchart illustrating processing of the guidance route calculation unit. First, in step S2001, the guidance route calculation unit 104 acquires information indicating the position of each area and the connection between the areas from the database of the spatial information management unit 105. Next, the guidance route calculation unit 104 acquires the increase / decrease information at the time t output from the congestion index comparison unit 103 in step S2002, and the acquired increase / decrease information in the spatial information management unit 105 in step S2003. Assign to each area in the information obtained from the database.

Further, in step S2004, the guidance route calculation unit 104 searches for a route between any two areas (nodes) in the network having each area as a node, which is constructed from the location and connection information of each area. Then, a guidance route that avoids an area indicating an abnormal congestion situation is calculated. At that time, the guidance route calculation unit 104 weights the movement time between the nodes with the increase / decrease information of the congestion index assigned to each area in the network, and performs a route search between any two areas (nodes). For the route search, for example, a Dijkstra algorithm or an A * algorithm known as a known route search method is used. Since the increase / decrease information of the congestion index is taken into consideration, a route detouring the area where the congestion index is increasing with respect to the standard value can be obtained as a search result. In step S2005, the guidance route calculation unit 104 outputs the route calculated in step S2004 and causes the information terminal 107 to display the route.

Next, route information calculated by the processing of the guidance route calculation unit 104 described above will be described.

FIG. 12 is a diagram showing an example of route information when there is no increase exceeding the threshold in the congestion index of each area. The route information output from the guidance route calculation unit 104 is indicated by a thick arrow in the drawing. As shown in FIG. 6, if the congestion index of each area does not increase so that the increase / decrease exceeds the increase / decrease threshold, the shortest route usually takes the shortest time to pass. In the example of FIG. 12, the route with the lowest cost when traveling from the node N407 (corresponding area A407) at the end of the platform to the node N414 (corresponding area A414) at the exit of the station outside the ticket gate is shown. . The cost of movement between nodes is, for example, the time required to move between the nodes. As can be seen from FIG. 12, the route with the shortest distance is the route with the minimum cost (the shortest required time).

FIG. 13 is a map display showing the position of each area in the monitoring target range and the state of congestion. In FIG. 13, a thin hatched area is a normal congestion situation area in which the increase / decrease information of the congestion index is equal to or less than the increase / decrease threshold. The dark hatched area is an area of an abnormal congestion situation in which the increase / decrease information of the congestion index exceeds the increase / decrease threshold. Here, as shown in FIG. 13, the increase in the congestion index exceeds the increase / decrease threshold in some areas A404, A405, A406, A408, and A413.

FIG. 14 is a diagram illustrating an example of route information in a case where an increase in the congestion index in a partial area exceeds the increase / decrease threshold. As illustrated in FIG. 13, when the increase in the congestion index in a partial area exceeds the increase / decrease threshold, the route information output from the guidance route calculation unit 104 is the route with the lowest cost in the situation. The route with the lowest cost is, for example, a route whose estimated time is estimated to be the shortest.

In FIG. 14, the route indicated by the thick arrow is a route whose start point and end point move from the node N407 at the end of the platform to the exit N414 of the station outside the ticket gate as in the route of FIG. However, the increase in the congestion index of the node N406 on the stairway on the route in FIG. 12, the node N405 on the floor above the staircase, and the node N404 on the ticket gate exceeds the increase / decrease threshold. Thus, when the congestion index increases by more than a predetermined value from the standard value, the cost of movement between nodes increases accordingly. Here, as a simple example, it is assumed that the cost required for movement between nodes in a normal congestion situation is constant. Then, the normal movement cost of a route is expressed by the number of nodes on the route. Further, here, the cost for a node in which the increase in the congestion index exceeds the increase / decrease threshold at the time of abnormality is set to 5 times that in the normal state.

In FIG. 12, eight vertices (nodes) of N407, N408, N406, N405, N404, N402, N401, and N414 are included on the path from the node N407 to the node N414 indicated by the bold arrow. If the increase in the congestion index of all nodes on the route is equal to or less than the increase / decrease threshold, the cost of moving the route is 8. However, as shown in FIG. 13, the increase in the congestion index exceeds the increase / decrease threshold at the nodes of the four vertices among the eight vertices. Therefore, the cost of moving the route from the node N407 to the node N414 is 24.

On the other hand, in FIG. 14, N407, N408, N409, N411, N412, N415, N416, N417, N418, N419, N403, N402, N401, N414 are on the path from the node N407 to N414 indicated by the thick arrow. 14 vertices are included. The increase in the congestion index exceeds the increase / decrease threshold at the node of one of the 14 vertices. Therefore, the cost of moving the route from the node N407 to the node N414 is 18.

In this way, the guidance route calculation unit 104 searches for a route with the lowest cost according to the state of each area, and outputs information about the obtained route. For example, a known Dijkstra algorithm can be used as a route search method.

Next, processing of the output unit 106 will be described.

FIG. 15 is a flowchart showing processing of the output unit. First, in step S3001, the output unit 106 acquires the position and connection information of each area from the database of the spatial information management unit 105. Next, in step S3002, the output unit 106 acquires increase / decrease information indicating increase / decrease of the congestion index of each area at time t output from the congestion index comparison unit 103. Subsequently, in step S3003, the output unit 106 allocates the increase / decrease information of the congestion index of each area at the acquired time t to each area in the information acquired from the spatial information management unit 105.

Next, in step S3004, the output unit 106 uses the increase / decrease information of the congestion index assigned to each area in step S3003 as an increase / decrease threshold value for determining whether the predetermined increase / decrease in the congestion index is normal or abnormal. By comparing, it is determined whether the congestion status of each area is normal or abnormal.

Further, in step S3005, the output unit 106 updates the display content information so that the display content of each area matches the normality / abnormality of the congestion status determined in step S3004, and outputs the updated information to the information terminal 107. Further, when the output unit 106 acquires the route information from the guidance route calculation unit 104, the output unit 106 also outputs the route information to the information terminal 107. The display contents of each area include displaying the congestion status with the display color of each area, or displaying an icon indicating the congestion status on or near the area display.

In addition, although the increase / decrease information of the congestion index is compared with one increase / decrease threshold here, the present invention is not limited to this. Compare the increase / decrease information of the congestion index assigned to each area with multiple increase / decrease thresholds set for each area, determine the degree of congestion abnormality, and indicate the degree of congestion condition abnormality or congestion state abnormality Information indicating the display content indicating the degree of the above may be output. Thereby, on the screen of the information terminal 107, for example, a map in which each area is color-coded according to the congestion status is displayed.

Also, the output unit 106 may output to the information terminal 107 information indicating that a congestion mitigation measure should be implemented for an area where the increase in the congestion index assigned for each area is large. In the information terminal 107, the area where the congestion alleviation measure should be implemented is displayed on the screen. At this time, if there are a plurality of areas where the congestion mitigation measures are to be executed, the output unit 106 may give priority to the implementation of the congestion mitigation measures to the plurality of areas. The priority order may be determined according to the increase / decrease information of the congestion index assigned to each area.

FIG. 16 is a diagram illustrating a display example of an area where the congestion mitigation measure in the information terminal is to be implemented. Here, since the increase / decrease information of the congestion index is high in the order of area A404, area A408, and area A420, it is assumed that priorities 1, 2, and 3 are given to area A404, area A408, and area A420, respectively. In FIG. 16, as the priority, the first priority is given to the area A404, and the “first priority” icon 701 is displayed. Area A 408 is given the second highest priority, and a “second priority” icon 702 is displayed. The area A420 is given the third highest priority, and the “third priority” icon 703 is displayed.

This completes the description of the processing of the output unit 106.

In the present embodiment, an example is shown in which information notified to passengers or station staff is visually displayed on the screen of the information terminal 107, but the present invention is not limited to this. As another example, information such as whether the congestion status of each area is normal or abnormal may be notified to passengers and station staff by voice.

<Effect>
According to this embodiment, the standard value of the congestion index for each time zone is provided for each area obtained by dividing the monitoring target range into a plurality of areas, and the congestion index and the standard value are compared for each area. Instead, it can be determined whether the congestion state is in a normal range. By using it, for example, you can notify areas where abnormal congestion occurs, and immediately identify areas that need to be dealt with preferentially, such as congestion reduction measures even at stations that are regularly congested Can do.

In addition, since it is determined whether the congestion status is normal or abnormal using a standard value calculated by statistical processing on the congestion index measured in the past, it is easy to detect signs of changes from the past congestion status.

In addition, it understands areas with normal congestion and abnormal areas, and calculates a guide route that avoids areas that show abnormal congestion, so passengers can be routed to avoid areas that show abnormal congestion. Can be guided.

As mentioned above, although this embodiment was described, this invention is not limited to these. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.
