Based on the information and the predicted number of passengers getting off at the second entrance 6b, the congestion information near the second entrance 6b is calculated. Here, the predicted number of people getting off the train may be, for example, the number of people getting off from the first boarding / alighting port 6a and the second boarding / alighting port 6b when the vehicle 4 arrives at the station, which is predicted from the past statistical data. The predicted number of passengers to get off may be, for example, the number of passengers who were in the area 8a and the area 8b when the vehicle 4 arrived at the station, which is predicted from the past statistical data. For the past statistical data, for example, the number of people getting off may be extracted from the past captured images taken by the first imaging device 7a and the second imaging device 7b.

Specifically, the relative congestion information is information indicating a high-low relationship between one of the congestion information near the first entrance / exit 6a and the congestion information near the second entrance / exit 6b and the other. The information processing device 1 compares the congestion information in the vicinity of the first entrance / exit 6a with the congestion information in the vicinity of the second entrance / exit 6b to obtain the congestion information in the vicinity of the first entrance / exit 6a and the second entrance / exit. The high-low relationship between one of the congestion information in the vicinity of 6b and the other is determined. For example, the information processing device 1 transmits to the server 2 information indicating a height relationship determined by comparing the population density near the first entrance / exit 6a and the population density near the second entrance / exit 6b. ..

If the electronic device 1 receives the relative congestion information via the server 2 and displays the relative congestion information on the display unit 13, the user of the electronic device 1 can use the first boarding / alighting port 6a and the second boarding / alighting port 6b. It becomes easier to determine from which side the vehicle 4 can be easily boarded.

The relative population density near the first entrance / exit 6a is a value obtained by dividing the population density near the first entrance / exit 6a by the average value of the population density near the entrance / exit installed in the vehicle 4. The relative population density near the second entrance / exit 6b is a value obtained by dividing the population density near the first entrance / exit 6b by the average value of the population density near the entrance / exit installed in the vehicle 4.

Further, when the population density of at least one of the vicinity of the first entrance / exit 6a and the vicinity of the second entrance / exit 6b satisfies a predetermined condition, the information processing device 1 transmits relative congestion information to the external device. May be good. For example, the information processing device 1 creates relative congestion information when at least one of the population densities in the vicinity of the first entrance / exit 6a and the vicinity of the second entrance / exit 6b is equal to or higher than a predetermined value. Relative congestion information may be transmitted to an external device. This predetermined value is, for example, a value calculated in advance by a known statistical method to be the minimum value that passengers feel uncomfortable when getting into a vehicle in the population density near the entrance / exit. According to such an information processing device 1, relative congestion information is sent to an external device at a timing when passengers feel uncomfortable when getting into the vehicle 4 at the vicinity of the first entrance / exit 6a and the vicinity of the second entrance / exit 6b. Can be sent.

If it is less than the value of), it is not necessary to transmit the relative congestion information to the external device. Further, when the population densities in the vicinity of the first entrance / exit 6a and the vicinity of the second entrance / exit 6b do not satisfy the above-mentioned predetermined conditions (that is, the population densities of the first entrance / exit 6a and the second entrance / exit 6b are the above-mentioned predetermined conditions.

Even if there is, it is possible to know that it is easy to get into the vehicle 4.

Further, if the electronic devices 3a and 3b cannot receive the congestion information near the first entrance / exit 6a and the congestion information near the second entrance / exit 6b from the server 2, the congestion information near the first entrance / exit 6a and the first It may be different from the display mode of the display unit 13 when the congestion information in the vicinity of the entrance / exit 6b of 2 is received. For example, the electronic devices 3a and 3b blink the blue LED lamp when the congestion information near the first entrance / exit 6a and the congestion information near the second entrance / exit 6b cannot be received from the server 2.

A person waiting for the vehicle 4 at the platform can easily know that the electronic devices 3a and 3b have not received the congestion information near the first entrance / exit 6a and the congestion information near the second entrance / exit 6b. ..

When the vehicle 4 arrives, the electronic devices 3a and 3b receive relative congestion information near the entrance / exit near the installation position of the own device from the server 2, and control the display unit 3 according to the received relative congestion information. You may. For example, in the electronic devices 3a and 3b, based on the received relative congestion information, when the vehicle 4 arrives, the population density near the entrance / exit near the installation position of the own device is close to the entrance / exit near the installation position of the other device. If it is judged that the population density is higher than that of the above, the red LED lamp is turned on. For example, in the electronic devices 3a and 3b, based on the received relative congestion information, when the vehicle 4 arrives, the population density near the entrance / exit near the installation position of the own device is close to the entrance / exit near the installation position of the other device. If it is judged that the population density is lower than that of the above, the yellow LED lamp is turned on.

A person waiting for the vehicle 4 at the platform can easily know the boarding position where it is easy to get into the vehicle 4 by checking the colors of the LED lights of the electronic devices 3a and 3b.
