- the notification of the boarding rate is performed by wireless communication.
- the boarding rate is transmitted together with the train identification information, the vehicle number information, and the like so that the main server 1 can recognize which vehicle of which train is the boarding rate.
- Information on the place (departure station) may be added so that the main server can recognize the boarding rate at which time point.
- the main server 1 makes an inquiry to the operation management system 5 and the like. The current position of the train can be recognized.
- step S2 when the main server 1 receives a notification of the boarding rate from the running train (onboard device 3), based on the notified boarding rate, immediately before each vehicle boarding at the station where this train stops next The congestion rate is calculated and transmitted to the station server 2 (step S2).
- the main server 1 acquires information on the rate of getting off at the next stop station of the train that is the notification of the boarding rate from the database 4, and uses the obtained rate of getting off and the notified rate of boarding immediately before boarding. Calculate the congestion rate.
- the main server 1 may separately build and hold a sub-database as shown in FIG. 4, for example, and obtain information on the getting-off rate from this sub-database.
- the main database the database of FIG. 2 (hereinafter referred to as the main database), the getting-off rate is managed in association with trains, times, stations, etc., but the sub-database shown in FIG. 4 is based on the information in the main database, This is generated so that the congestion rate immediately before boarding can be calculated efficiently.
- the sub-database shown in the figure extracts records common to “station” and “home” from the records registered in the main database, and further, “month / day”, “hour / minute”, “weekday / holiday” ”,“ Train type ”, and“ destination ”for grouping and calculating the average value of the alighting rate classified into the same group and creating a database.
- This sub-database is generated for each platform of the station.
- the date period
- the hour and minute (time zone) are divided into commuting rush time, return rush time, and other times.
- the way of dividing the time zone may be different.
- the date may be divided in units of 1 week or 10 days.
- the hour and minute may be divided into early morning, morning, daytime, evening, evening, etc., or simply in units of N hours. Further, other information may be included, and unnecessary information may be deleted. For example, if the getting-off rate hardly changes even if the period (month / day), train type, and destination are different, these train type and destination items may be deleted. For stations where only ordinary trains stop, the train type is unnecessary and may be deleted. If the congestion rate information just before boarding is provided only on weekdays, the weekday / holiday item may be deleted. Thus, the configuration (information to be managed) of the sub-database may be different for each station. However, at least the time zone (hours and minutes) and the unloading rate for each vehicle need to be included.
- the station server 2 (station server 2 at station B) displays the information on the display device 6 installed at the platform where the train corresponding to this information arrives based on the congestion rate just before boarding received from the main server 1.

- the congestion rate immediately before boarding for each train of the next arriving train (the expected result of the congestion rate at the time when getting off is finished and boarding is started) to the user on the home
- the notification method does not matter. You may notify only with a text (a letter and a number), and you may notify using an image (for example, figure which shows the organization of a train).
- the on-board device 3 of this train monitors the change in the congestion rate (boarding rate) of each vehicle while the station is stopped, and the minimum value of the congestion rate (hereinafter, Measure the minimum congestion rate during stoppage for each vehicle and send the measurement results (minimum congestion rate during stoppage of each vehicle) to the main server 1 or calculate the get-off rate based on the measurement results and calculate The obtained getting-off rate is transmitted to the main server 1 (step S4).
- the congestion rate is continuously calculated based on the detection result of the AS pressure (vehicle weight).
- the congestion rate is the lowest when the user finishes getting off (immediately before the start of boarding), so the lowest congestion rate during stoppage is the user who has been waiting for the arrival of the train at the station. Shows the congestion rate just before. That is, the lowest congestion rate during stop is the same information as the congestion rate immediately before boarding described above. The difference between them is that the lowest congestion rate during stop is the actual congestion rate (measured value), whereas the congestion rate immediately before boarding is the predicted congestion rate (predicted value). It is desirable that the predicted value is close to the actually measured value.
- the on-board device 3 also transmits information required by the main server 1 (for example, information on the location and information on the train) when transmitting the measurement result or the getting-off rate.
- the main server 1 updates the database 4 (main database) based on the information received from the on-board device 3 (the lowest congestion rate or the getting-off rate during stoppage, and information transmitted together therewith). (Step S5).
- the main server 1 receives the getting-off rate calculated by the on-board device 3, the main server 1 registers the getting-off rate in the database 4 in association with time information, place information, train information, and other information.

- the user on the platform of the station can check the display device 6 installed in the platform and know the congestion rate for each vehicle of the next arrival train.
- This congestion rate is a congestion rate predicted in consideration of the actual congestion rate (ride rate) of the running train and the number of users getting off at the station, so it simply notifies the actual congestion rate of the arriving train.
- the conventional guidance display it is possible to provide more useful information for the user. As a result, it can contribute to realization of vehicle congestion reduction and boarding rate averaging.
- FIG. 5 is a flowchart showing an operation performed by the on-board device 3 after the train leaves the station, and shows an operation example when executing the above-described step S1.
- the on-board device 3 monitors whether the train has started when it is stopped at the station (step S11). As a result of monitoring, when it is detected that the vehicle has started (step S11: Yes), it is determined whether or not the next station (next stop station) is a station that displays the congestion rate immediately before boarding (step S12). This determination is made based on, for example, whether or not a display device that performs guidance display is installed. A list of stations to be displayed (database) or the like may be created and held, and this list may be confirmed and determined. In the case of “no congestion just before boarding” (step S12: No), the process proceeds to step S11 to monitor arrival at the next station and departure.
- the on-board device 3 calculates a boarding rate (congestion rate during travel) for each vehicle (step S13).
- the occupancy rate is calculated using vehicle weight or the like. Since the vehicle weight is measured by a train information management system or the like, information on the vehicle weight is obtained from the vehicle information and calculated.
- the on-board device 3 obtains in advance a reference vehicle weight such as a vehicle weight in a state where the boarding rate is 0% (a state in which the user does not get on at all) from a train information management system or the like.
- the on-board device 3 may acquire the boarding rate from the train information management system.
- this boarding rate is transmitted to the main server 1 on the ground as train information together with the next stop station, destination, train number, and train type (step S14).
- the information transmitted to the main server 1 is not limited to the above. Further, a larger amount of information may be transmitted, or a minimum amount of information may be transmitted to suppress the amount of information to be wirelessly transmitted. For example, at least the boarding rate and train identification information (organization number) may be transmitted. If the composition number is known, the main server 1 can obtain information such as the next stop station and destination of this composition (train) by making an inquiry to the operation management system 5.
- the on-board device 3 transmits the boarding rate and information related thereto to the main server 1.
- the boarding rate is obtained using the vehicle weight, it may be obtained using other than the vehicle weight. For example, by using a camera installed in the vicinity of a door, the number of passengers and the number of people getting off at the station stop may be monitored, and the boarding rate may be calculated based on the monitoring result after leaving the station. Any other method may be used as long as the boarding rate can be obtained.
- the on-board device 3 holds the calculated (or acquired) boarding rate for use in calculating the getting-off rate described later.

- the “special day” means, for example, a day when there are events around the station and it is estimated that there are more users at the station than usual.
- the congestion rate immediately before boarding is transmitted to the station server 2. No (Does not calculate congestion rate just before boarding). That is, the guidance information on the congestion rate immediately before boarding is not displayed at the next stop station (step S25).
- step S22 the train information received from the on-board device 3, the information registered in the database 4, and the corresponding train managed by the operation management system 5 (above Based on the platform information of the next stop station of the train on which the on-board device 3 as the transmission source of the train information is installed, the congestion ratio immediately before boarding at the next stop station of the corresponding train is calculated (step S23).
- the calculation method of the congestion rate immediately before boarding is shown.
- the main server 1 preliminarily creates and holds the sub-database shown in FIG. 4 based on information registered in the database 4 (see FIG. 2). However, it is not essential to create and store this sub-data in advance.
- the congestion rate immediately before boarding may be calculated by directly using information registered in the main database (database 4).
- the main server 1 When calculating the congestion rate immediately before boarding, first, the main server 1 refers to the sub-database in FIG. 4 and acquires the getting-off rate used in the calculation process. Note that the sub-database as shown in FIG. 4 is constructed for each platform at each station on the route, and is held in the main server 1 or in an external storage unit (not shown).
- the drop-off rate After identifying the sub-database corresponding to the stop platform at the next stop station, refer to the records managed in the identified sub-database, and the month and day (period), hour and minute (time zone)
- the get-off rate (get-off rate of each vehicle) registered in the record in which the weekday / holiday (day type), the train type, and the destination match.
- the drop-off rate is an average value of actual drop-off rates (actual values) under the same past conditions (trains having the same period, time zone, day type, train type, and destination).
- the main server 1 transmits the congestion rate immediately before boarding calculated for each vehicle calculated in step S23 to the station server 2 of the corresponding station (the next stop station of the train) together with the train number and arrival platform information. (Step S24).
- the information transmitted to the station server 2 is, for example, as shown in FIG.
- the congestion rate immediately before boarding is not calculated / transmitted, but the congestion rate just before boarding is calculated by using a special formula for special days. May be calculated and transmitted. You may make it transmit not the congestion rate just before boarding but the congestion rate of the vehicle in progress (boarding rate contained in the train information received from the onboard apparatus 3) as it is. At this time, it is desirable to add the information indicating that it is a normal congestion rate (congestion rate of a running vehicle) that is not the congestion rate immediately before boarding, and transmit it.
- the main server 1 calculates the congestion rate immediately before getting on each vehicle of the running train (the congestion rate at the time of getting off after arriving at the next stop station), and the calculated information is used as this information. It transmits to the station server 2 which uses and displays guidance.
- FIG. 8 is a flowchart showing an operation performed when the station server 2 receives the congestion rate immediately before boarding from the main server 1, and shows an operation example when executing the above-described step S3.

- step S31: Yes when the congestion rate immediately before boarding is received (step S31: Yes), content for guiding the congestion rate immediately before boarding is generated (step S32). Then, the content for congestion rate guidance immediately before boarding is displayed on the display device 6 installed in the corresponding home (home where the train arrives) (step S33).
- the timing for displaying the content for congestion rate guidance immediately before boarding is, for example, (1) a timing according to a predetermined display sequence.
- the display timing is scheduled in advance, and the display is switched according to the display schedule together with other displays (such as advertisement content and destination display). If the content of the congestion rate guidance content just before boarding has not been generated at the time when the content of the congestion rate guidance content immediately before boarding has been displayed, the display is skipped. (2) Interrupted when content creation is completed It is possible to display and continue the display for a predetermined time. (3) After the creation of the content is finished, display is started at a specific timing and continued until the train arrives. Of course, it may be other than these.

- step S42 the lowest boarding rate (congestion rate) while the station is stopped is collected.
- step S42 the on-board device 3 monitors fluctuations in the boarding rate of each vehicle, for example, by monitoring the vehicle weight. Then, the lowest value of the boarding rate detected until the train leaves the station is detected as “the lowest boarding rate while the station is stopped”.
- the on-board device 3 detects the detection result (the lowest occupancy rate while the station is stopped) and the occupancy rate that was retained when the processing shown in FIG. 5 was executed (before the train arrived at the station). Based on the traveling rate (which corresponds to the boarding rate during traveling), the getting-off rate at this stop station is calculated (step S43).
- the lowest boarding rate while the vehicle is stopped is the lowest congestion rate during stopping as described above, and is the same information as the congestion rate immediately before boarding described above.
- this drop-off rate is information indicating how much the boarding rate (congestion rate) at the time of arrival at the station when the user's getting off at the stop station has changed. It shows that the congestion rate is greatly reduced by the user getting off at the station.

The average value of the unloading rate extracted from 1 and included in each extracted record is calculated.
- the change in the boarding rate (congestion rate) of the arriving train at each station on the route and the boarding rate at the end of getting off at the station are calculated. It was decided to monitor and collect the getting-off rate indicating how much the boarding rate would change (decrease) at the end of the user's getting-off. Also, based on the boarding rate while the train is running and the getting-off rate registered in the database, the congestion rate just before getting on the train (the congestion rate at the end of getting off) of the arriving train is calculated, and the calculated congestion rate just before getting on the station The user is notified using a display device on the home.
- the congestion rate immediately before boarding calculated by the main server 1 during traveling of the train and the getting-off rate calculated by the onboard device 3 while stopping at the station are similar information, and the congestion rate immediately before boarding, which is a predicted value, is an actually measured value. He explained that it would be desirable to get closer to a certain drop-off rate. Therefore, in order to improve the prediction accuracy, the difference between the two may be calculated and stored in a database after the getting-off rate is obtained, and the congestion rate immediately before boarding may be corrected using the difference database.
- the difference is stored in the database 4 in association with the getting-off rate, and when calculating the getting-off rate (average value) to be registered in the sub-database, the average value of the difference is also calculated and registered in the sub-database. And when calculating the congestion rate just before boarding, the congestion rate just before boarding is correct
