Abstract

PURPOSE:To eliminate the passage congestion at a gate and also to attain an unmanned gate by setting automatically the passable volume based on the passage volume information and with use of a fuzzy inference. CONSTITUTION:A fuzzy arithmetic circuit 2 uses the traffic volum information received from a history memory 5 storing the past passage volume, a train information memory 6 storing the depature/arrival time sof trains, an environment memory 7 storing the weather and the external environment, and a ticket vendor information input part 8 respectively as the input variables. Then the circuit 2 carries out a fuzzy inference based on a fuzzy rule and a membership function received from a membership function setting part 11 and decides the passage information on a gate. In regard of the fuzzy rule, the station-to-outside one-way pass value is increased when a large number of passengers pass through an outgoing gate. Meanwhile the outside-to-station one-way pass value is increased when a large number of passengers pass through an incoming gate respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of a traffic control device according to an embodiment of the present invention. Traffic control device 1
are a fuzzy arithmetic circuit 2, a gate control circuit 3, a weather information input section 4, a history memory 5, a train information memory 6, an environment memory 7, a ticket vending machine information input section 8, a timer 9, a membership function setting section 11, and a buffer 12. It is made up of. Current weather information is input from the weather information input section 4 to the membership function setting section 11. The membership function setting unit 11 stores in advance fuzzy rules and membership functions for rainy weather and fuzzy rules and membership functions for sunny weather, and is configured according to the weather information input from the weather information input unit 4. Any one of the fuzzy rules and membership functions is output to the fuzzy arithmetic circuit 2.

The history memory 5 stores information such as the past traffic volume at the gate, and the past traffic state is stored in the history memory 5 based on the output data of the timer 9 and counter 10 attached to the gate. There is. That is, the history memory 5 stores the past traffic volume of gates for each time period and for each direction of traffic. The train information memory 6 stores train departure and arrival times and train types. The environment memory 7 stores information about the external environment specific to the location where the gate is installed, such as whether it is a residential area or a shopping area. The ticket vending machine information input section 8 collects ticket issuing data from the ticket vending machine, and inputs the collected data to the fuzzy arithmetic circuit 2 as ticket vending machine information.

The fuzzy arithmetic circuit 2 uses these history memories 5
, the passing direction and amount of traffic information input from the train information memory 6, environment memory 7, and ticket vending machine information input unit 8, the passing direction and amount of passage through a one-way gate, and the time interval for inserting tickets at the gate. Fuzzy inference is performed according to the fuzzy rules and membership functions output from the membership function setting unit 11, using traffic information such as train departure/arrival times and types, past traffic volumes, ticket vending machine information, weather, and external environment as input variables. Execute.

An example of a fuzzy rule set in the fuzzy calculation circuit 2 from the membership function setting unit 11 is to restrict one-way traffic from the station (gate A in FIG. 2) when there are many people passing through the ticket gate. If there are many people passing through the bidding gates, the number of one-way gates (gate B in Figure 2) from outside to inside the station may be increased. Furthermore, if the time for the train to arrive is near, the number of gates B shown in FIG. 2 is increased, and if the number of tickets issued by the ticket vending machine increases, the number of gates B is similarly increased. Further, an example of membership functions set in the fuzzy arithmetic circuit 2 is shown in FIG. Known fuzzy inference is performed according to such fuzzy rules and membership functions.

FIG. 4 is a flowchart showing the processing procedure in the traffic control device. The traffic control device 1 transfers environmental data from the environmental memory 7 to the fuzzy control circuit 2 at predetermined time intervals (n1), and based on the weather information transmitted from an external communication network etc., the membership function setting unit 11 It is determined which fuzzy rules and membership functions are to be set, and these are set in the fuzzy arithmetic circuit 2 (n2). Next, train departure/arrival times and train type information for, for example, five trains are transferred from the train information memory 6 to the buffer 12 (n3), and when the current time becomes one minute before the train departure/arrival time, that time is transferred from the history memory. Data on the amount of people passing along the belt and the direction of traffic are transferred to the fuzzy calculation circuit 2 (n4, n5). After that, the ticket vending machine information input section 8 outputs the ticket issuing status to the fuzzy calculation circuit 2 (n6), and the current traffic information at the automatic ticket gate obtained from the timer 9 and counter 10 is output to the fuzzy control circuit 2 (n7). ). Fuzzy inference is executed in the fuzzy arithmetic circuit 2 based on the various input data obtained in this way, and gate traffic information at the automatic ticket gate is determined (n8).

Note that the ticket vending machine information input unit 8 may be configured to transmit the ticket issuing status of ticket vending machines at other stations via a communication network not shown. In addition, the fuzzy arithmetic circuit 2
may infer the number of gates in operation as well as the traffic direction of the gate.

[0016]

[Effects of the Invention] According to the present invention, the amount of traffic allowed at the gate can be automatically set based on the information on the amount of traffic at the gate, thereby eliminating congestion at the gate and reducing the effort required to switch traffic conditions. This has the advantage of eliminating the need for gates and making the gate unmanned. Furthermore, by using fuzzy inference means to set the allowable traffic volume, the state of the gate can be precisely controlled based on the traffic volume information.
