Introduction of the Profile Control System by the Autonomy Dispersion Method Into Traffic Signal Controllers in an Existing Central Control Area

This report describes a demonstration model constructed and operated by Shizuoka Prefectural Police, first in Japan, according to the instructions of the National Police Agency, wherein the profile control system by the autonomous type has been introduced to control traffic signal controllers in an existing centralized control area, thereby traffic congestion has been reduced while preventing traffic accidents from occurrence. According to this novel profile control system, traffic signal controllers installed at an intersection does not wholly depend on the signal control system at the traffic control center, but the system estimates in real time how many vehicles will enter the intersection and how soon, referring to the data of traffic volumes gathered from vehicle detectors upstream of the intersection and the signal control data transmitted from the adjacent intersections, thus the traffic signal controllers are optimally controlled. One of the aims of this demonstration is to resolve traffic congestion caused by a delay of con trolling, a common problem of conventional control systems. The Shizuoka Prefectural Police has introduced the profile control system into 30 intersections in Iwata City, and has begun its operations as from April 1, 2010.
