TRAFFIC SIGNAL CONTROLLER, ARRIVAL TIME POINT INFORMATION GENERATION DEVICE, COMPUTER PROGRAM, AND TRAFFIC SIGNAL CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a traffic signal controller, an arrival time point information generation device, a computer program and a traffic signal control method, allowing high-accuracy calculation of a vehicle profile, and allowing improvement of accuracy of signal control.;SOLUTION: A travel time calculation part 45 calculates a traveling required time between a time point when passing a stop line of a crossing and a time point when passing a spot wherein a vehicle sensor is installed as a travel time. In this case, the travel time calculation part 45 excludes the travel time of a vehicle traveling at a low speed or a vehicle having decelerated. A vehicle profile calculation part 46 calculates the vehicle profile based on a detection result of a passing vehicle in the vehicle sensor. In this case, the vehicle profile calculation part 46 calculates the vehicle profile by use of the travel time (the travel time calculated except the travel time to the vehicle traveling at the low speed or the vehicle having decelerated) calculated in the travel time calculation part 45.;COPYRIGHT: (C)2010,JPO&INPIT
