Hereinafter, an example of the embodiment of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components and parts are given the same reference numerals. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios.

FIG. 1 is a diagram showing a schematic configuration of a congestion degree calculation system according to the present embodiment. The congestion degree calculation system shown in FIG. 1 periodically acquires location information and provides the server 10 with a server 10 which is an example of a congestion degree calculation device for calculating the congestion degree of transportation. It includes terminals 20A and 20B, and a digital signage 30 that displays information on the degree of congestion of transportation calculated by the server 10. The server 10, the terminals 20A and 20B, and the digital signage 30 are connected to each other so as to be communicable by the network 40.

The server 10 is configured to calculate the degree of congestion of transportation based on the position information acquired by the terminals 20A and 20B. Specifically, the server 10 analyzes the position information periodically acquired by the terminals 20A and 20B, and determines which terminal is the terminal of the user who is using the transportation system. Then, the server 10 calculates the number of terminals of the user who is using the transportation, and calculates the degree of congestion of the transportation based on the calculated number of terminals.

The terminals 20A and 20B are terminals used by the user, respectively, and have a function of acquiring information on the current position. The terminals 20A and 20B are configured to acquire information on the current position by GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System). The terminals 20A and 20B may be any terminals such as smartphones, tablet terminals, wristwatch-type devices, etc., as long as they can acquire information on the current position and have a communication function with the server 10. The terminal 20 may determine the acquisition timing of the position information by the terminal 20. Further, the terminal 20 may acquire the position information by sending an instruction from the server 10 to the terminal 20.

The degree of congestion calculated by the server 10 can be visually presented to the terminals 20A, 20B, or the digital signage 30 as congestion information of transportation. The visually presented transportation congestion information will be illustrated later.

Since the server 10 according to the present embodiment calculates the degree of congestion of transportation based on the position information acquired from the terminals 20A and 20B existing at predetermined positions, it is not necessary for the terminals 20A and 20B to calculate the degree of congestion. .. Further, since the server 10 according to the present embodiment calculates the degree of congestion of transportation based on the position information acquired from the terminals 20A and 20B, the degree of congestion can be calculated without using the information of transportation.

In the following description, when it is not necessary to distinguish the terminals 20A and 20B, the terminals 20A and 20B are collectively referred to as the terminal 20.

FIG. 2 is a block diagram showing a hardware configuration of the server 10.

As shown in FIG. 2, the server 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a display unit 16, and a communication interface (I). / F) has 17. The configurations are connected to each other via the bus 19 so as to be communicable with each other.

The CPU 11 is a central arithmetic processing unit that executes various programs and controls each unit. That is, the CPU 11 reads the program from the ROM 12 or the storage 14, and executes the program using the RAM 13 as a work area. The CPU 11 controls each of the above configurations and performs various arithmetic processes according to the program recorded in the ROM 12 or the storage 14. In the present embodiment, the ROM 12 or the storage 14 stores a congestion degree calculation program for calculating the congestion degree of transportation.

The ROM 12 stores various programs and various data. The RAM 13 temporarily stores a program or data as a work area. The storage 14 is composed of a storage device such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory, and stores various programs including an operating system and various data.

When executing the above-mentioned congestion degree calculation program, the server 10 realizes various functions by using the above-mentioned hardware resources.

Next, the functional configuration realized by the server 10 will be described.

FIG. 3 is a block diagram showing an example of the functional configuration of the server 10.

As shown in FIG. 3, the server 10 has an acquisition unit 101, a measurement unit 102, a calculation unit 103, and a congestion information providing unit 104 as functional configurations. Each functional configuration is realized by the CPU 11 reading and executing the congestion degree calculation program stored in the ROM 12 or the storage 14.

The acquisition unit 101 periodically acquires the position information of the terminal 20 acquired by the terminal 20 from the terminal 20. The position information of the terminal 20 acquired by the acquisition unit 101 is used in the measurement process of the terminal 20 of the user who is using the transportation system in the measurement unit 102.

The measurement unit 102 measures the number of terminals 20 of the user who is using the transportation system by using the position information of the terminal 20 acquired by the acquisition unit 101. The measurement unit 102 determines whether or not the user who owns the terminal 20 is using the transportation system by using the time series data of the position information of the terminal 20. Then, the measuring unit 102 measures the number of terminals 20 possessed by the user who has determined that he / she is using the transportation system. For example, the measuring unit 102 measures the number of terminals existing in a predetermined range (in a train car, in a bus, etc.) using time-series data of the position information of the terminal 20. On the other hand, the terminal 20 owned by the user who has determined that the measurement unit 102 is not using the transportation system is excluded from the measurement.

When measuring the number of terminals 20 of users using transportation, the measuring unit 102 may, for example, extract those that move in the same direction and at the same speed as the surrounding terminals 20 at the same timing. .. For example, when the acquisition unit 101 acquires the position information of the terminal 20 at a certain time N and time N + 1, the measurement unit 102 acquires the difference in the position information between the time N and the time N + 1, and is the same at the same timing. A terminal 20 that moves in the same speed in the direction may be determined to be a terminal 20 possessed by a user using transportation. If transportation is used, the terminal 20 of the user using transportation will move in a mass to some extent. Therefore, the measurement unit 102 acquires the difference in the position information between the time N and the time N + 1, and regards the mass moving to some extent as the number of terminals 20 of the user using the transportation system.

The measuring unit 102 may refer to the position information of the route of the railroad track or the bus route when measuring the number of terminals 20 of the user using the transportation system. For example, when the number of terminals 20 is measured by extracting the terminals 20 that are moving in a mass as described above, the measuring unit 102 can refer to the position information of the route of the line or the bus line. Alternatively, the terminal 20 acquired at a place other than the bus route can be excluded. Therefore, the measuring unit 102 can measure the number of terminals 20 more accurately by referring to the position information of the route of the railroad track or the bus route, as compared with the case where the position information of the route of the railroad track or the bus route is not referred to. ..

The measuring unit 102 may refer to the moving speed of the terminal 20 when measuring the number of terminals 20 of the user who is using the transportation system. For example, the measuring unit 102 measures the number of terminals 20 when the moving speed of the terminal 20 is equal to or higher than the predetermined value, and measures the number of terminals 20 when the moving speed of the terminal 20 is less than the predetermined value. It may be excluded from the target. The moving speed of the terminal 20 is obtained from the time interval between the time N and the time N + 1 and the distance between the respective terminals 20 between the time N and the time N + 1. By targeting the number of terminals 20 to be measured when the moving speed of the terminal 20 is equal to or higher than a predetermined value, the measuring unit 102 uses transportation when a certain amount of time has passed after leaving the station or the bus stop. The number of terminals 20 of the user can be measured.

The timing of reporting the location information acquired by the terminal 20 to the server 10 may be different. If the number of terminals 20 is measured based on the position information reported from each terminal 20 at different timings, the number of terminals 20 of the user using the transportation system cannot be accurately obtained. Therefore, the measurement unit 102 may refer to the date and time when the position information is reported from the terminal 20, and may measure the number of terminals 20 for those whose position information is reported close to the date and time (for example, within 15 seconds). Then, the measurement unit 102 may estimate the number of terminals 20 of the user by summing the measurement results of the number of terminals 20 a plurality of times.

When the server 10 can always communicate with the terminal 20, the timing for reporting the position information from the server 10 to each terminal 20 may be specified. By designating the timing at which the server 10 reports the position information to each terminal 20, the measurement unit 102 can more accurately measure the number of terminals 20 of the user who is using the transportation system.

Further, as a method for determining a predetermined range, if it is a train, the position of the head of the train may be specified and the length from the head (if one car is 20 meters, 20 meters x the number of vehicles) may be used. For the position of the head of the train, for example, the position information acquired in the driver's seat of the train may be used. As for the information on the number of vehicles, data on the type of the train may be obtained from a railway company or the like.

The calculation unit 103 calculates the degree of congestion of the transportation system by using the number of terminals 20 of the users who are using the transportation system measured by the measurement unit 102. The calculation unit 103 may calculate the degree of congestion of transportation as a percentage, or may calculate which of the five stages, for example, the degree of congestion.

The calculation unit 103 may divide a predetermined range corresponding to a train vehicle, a bus, or the like into a predetermined number, and calculate the degree of congestion for each divided area. The calculation unit 103 can derive the degree of congestion for each vehicle by calculating the degree of congestion for each divided region.

The congestion information providing unit 104 provides the terminal 20 or the digital signage 30 with congestion information, which is information that visualizes the congestion degree of the transportation system calculated by the calculation unit 103. An example of congestion information provided by the congestion information providing unit 104 will be described in detail later.

By having the functional configuration shown in FIG. 3, the server 10 measures the number of terminals 20 of users who use transportation, and calculates the degree of congestion of transportation based on the measured number of terminals 20. Can be done. Then, by having the functional configuration shown in FIG. 3, the server 10 can provide the terminal 20 or the digital signage 30 with the congestion information that visualizes the congestion degree of the transportation system.

Next, the operation of the server 10 will be described.

FIG. 4 is a flowchart showing the flow of the congestion degree calculation process by the server 10. The congestion degree calculation process is performed by the CPU 11 reading the congestion degree calculation program from the ROM 12 or the storage 14, expanding the congestion degree calculation program into the RAM 13, and executing the program.

The CPU 11 periodically acquires the position information of the terminal 20 acquired by the terminal 20 from the terminal 20 (step S101).

Following step S101, the CPU 11 uses the acquired time-series data of the position information of the terminal 20 to determine whether or not the user possessing the terminal 20 is using transportation (step S102). The CPU 11 determines that the terminal 20 existing in a predetermined range (in a train vehicle, in a bus, etc.) is a terminal 20 of a user who is using transportation.

When the CPU 11 acquires the position information of the terminal 20 at a certain time N and the time N + 1, the CPU 11 acquires the difference between the position information between the time N and the time N + 1. Then, the CPU 11 may determine whether or not the user who owns the terminal 20 is using the transportation system, depending on whether or not the user is moving in the same direction and at the same speed as the surrounding terminals 20 at the same timing.

FIG. 5 is a diagram schematically showing the positions of the terminals 20 acquired by the terminals 20 respectively. FIG. 5A schematically shows the position of the terminal 20 acquired by the terminal 20 at a certain time N, and FIG. 5B shows the terminal 20 acquired by the terminal 20 at a certain time N + 1. The position of is shown schematically.

The position of a user on a transportation system such as a train moves with a certain amount of mass as time changes. Therefore, the CPU 11 extracts the terminal 20 that is changing with a certain amount of mass from the difference in the position information of the terminal 20. In the example of FIG. 5, the mass at the position of the terminal 20 indicated by the reference numeral 200 corresponds to the terminal 20 in the transportation system such as a train.

FIG. 6 is a diagram schematically showing the position of the terminal 20 of the user on the train. As shown in FIG. 6, in the case of a train, the position of the head of the train is specified, and the length from the head (20 meters x number of vehicles if one car is 20 meters) can be used as the range of the train. good. For the position of the head of the train, for example, the position information acquired in the driver's seat of the train may be used. As for the information on the number of vehicles, data on the type of the train may be obtained from a railway company or the like.

As a result of the determination process in step S102, the CPU 11 determines whether or not it is determined that the user possessing the terminal 20 is using the transportation system (step S103).

As a result of the determination in step S103, if the user possessing the terminal 20 is using the transportation system (step S103; Yes), the CPU 11 counts the terminal 20 (step S104). On the other hand, as a result of the determination in step S103, if the user possessing the terminal 20 does not use the transportation system (step S103; No), the CPU 11 excludes the terminal 20 from the counting target (step S105). ). In the example of FIG. 5, the CPU 11 targets the terminal 20 in the range indicated by the reference numeral 200 as the counting target, and excludes the other terminals 20 from the counting target.

Following step S104 or step S105, the CPU 11 measures the number of terminals 20 to be counted (step S106).

Following step S106, the CPU 11 calculates the degree of congestion of transportation based on the measured number of terminals 20 (step S107). The CPU 11 uses information on the capacity of each transportation system acquired in advance when calculating the degree of congestion. For example, if the capacity of one train train is 1000 and the number of measured terminals 20 is 800, the CPU 11 may calculate the degree of congestion as 80%. Further, the CPU 11 may calculate the degree of congestion in a predetermined stage, for example, four stages. The CPU 11 includes the measured number of terminals 20 divided by the capacity of one train in four stages of 0 to 0.5, 0.5 to 1, 1 to 1.5, and 1.5 or more. You may calculate the degree of congestion depending on the situation.

When calculating the degree of congestion, the CPU 11 may calculate the degree of congestion of the entire train or bus train, or may calculate the degree of congestion per vehicle. The CPU 11 may also calculate the degree of congestion per vehicle in a predetermined stage, for example, four stages. The CPU 11 may acquire information on the number of train or bus vehicles from transportation when calculating the degree of congestion per vehicle.

FIG. 7 is a diagram schematically showing the position of the terminal 20 of the user on the train. FIG. 7 schematically shows the position of the terminal 20 for each vehicle by equally dividing the range of the train by the number of vehicles (10 vehicles in FIG. 7). By equally dividing the range of the train in this way, the CPU 11 can measure the number of terminals 20 per vehicle and calculate the degree of congestion for each vehicle.

Following step S107, the CPU 11 generates congestion information from the congestion degree calculated in step S107, and provides the generated congestion information to the terminal 20 or the digital signage 30 (step S108).

The CPU 11 can measure the number of terminals 20 of users who use transportation by executing a series of processes shown in FIG. 4, and calculate the degree of congestion of transportation based on the number of terminals 20. can. Then, the server 10 can provide the terminal 20 or the digital signage 30 with the congestion information that visualizes the congestion degree of the transportation system by executing the series of processes shown in FIG.

Subsequently, an example of congestion information provided by the server 10 to the terminal 20 or the digital signage 30 will be shown.

FIG. 8 shows an example of congestion information of a train arriving at a certain station on a certain date and time. In FIG. 8, the numbers indicate the train number. FIG. 8 shows a case where the degree of congestion is calculated in four stages and the congestion information is provided to the terminal 20 with a symbol corresponding to the calculated degree of congestion. In the example of FIG. 8, the double circle corresponds to "very empty", the circle corresponds to "empty", the triangle corresponds to "crowded", and the cross corresponds to "very crowded". In this way, by providing the congestion information with the symbols corresponding to the degree of congestion, the server 10 uses the terminal 20 or the digital signage in a form that is visually easy to understand, as compared with the case where the calculated degree of congestion is simply provided numerically. 30 can be provided.

The user can use the terminal 20 to inquire to the server 10 how busy the transportation system such as the train or bus to be boarded is. For example, it is assumed that the user operates a route search application installed in the terminal 20 and inquires the server 10 about the congestion information of the three latest trains arriving at the station designated by the user. The server 10 provides the terminal 20 with information on the congestion of the three most recent trains arriving at the station designated by the user. FIG. 9 is a diagram showing an example of congestion information presented to the terminal 20. In FIG. 9, the numbers indicate the train number. The user can determine which train and which vehicle to ride by looking at the congestion information presented on the terminal 20 as shown in FIG.

When providing the congestion information to the terminal 20 or the digital signage 30, the server 10 may provide the congestion information in combination with the past congestion information. For example, when the server 10 provides the congestion information to the terminal 20 or the digital signage 30, the server 10 may provide the congestion information in combination with the congestion information of a predetermined transportation in a predetermined time zone in the latest one week. By referring to the past congestion information, the user can select a non-congested time zone and determine the commuting time or the commuting time.
