TRAFFIC SIGNAL CONTROLLER AND TRAFFIC SIGNAL CONTROL METHOD AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To optimally facilitate countermeasures to the rapid variation of traffic circumstances by dynamically changing a signal control parameter by highly precisely recognizing the change of traffic circumstances in a time being the target of control. SOLUTION: An information transmitting part 4 transfers outgoing traffic flow information with an adjacent traffic signal controller 1. An incoming information preparing part 10 prepares an incoming traffic flow table showing incoming results in a fixed time until the present time and the predicted number of incoming traffic in the near future by using the received outgoing traffic flow information and traveling time from an adjacent intersection. A signal control constant number calculating part 9 calculates a signal control parameter such as cycle length or split to several cycles ahead as necessary based on traffic demands in the near future to be acquired from the prepared incoming traffic flow table. An outgoing information preparing part 8 prepares the outgoing traffic flow information by predicting the outgoing traffic flow rate in each fixed time by using the outgoing traffic flow rate measured by a traffic flow rate measuring part 6 and the prepared incoming traffic flow table and a branch rate and a signal control parameter.
