SYSTEM CONTROLLING TRAFFIC SIGNAL BASED ON TRAVEL TIME INFORMATION AND METHOD THEREOF

摘要

PURPOSE: A travel time-based traffic signal control system and a method thereof are provided to control a traffic signal according to the amount of traffic in real time by distributing phase signals according to delay variations. CONSTITUTION: A vehicle information collection part(1) collects the travel time information of a vehicle. A traffic signal control part(2) computes traffic time delay according to a road. The traffic signal control part computes the amount of delay variations. The traffic signal control part distributes a phase signal according to the amount of delay variations. A traffic signal display part(4) displays the phase signal.
