PACKET TRAFFIC CONTROL SYSTEM

A traffic control system includes: a vehicle detection sensor (CS) for detecting a vehicle on a road; a traveling speed command indicator (VI) for indicating a traveling speed command to the vehicle on the road; a vehicle train detection means (104) for detecting a vehicle train in which vehicles range with each other within a predetermined inter-vehicle distance; a packet formation control means (106) for indicating a traveling speed command to form a packet having predetermined vehicle train length and inter-vehicle train distance for the vehicle on the road; a packet traveling control means (108) for indicating a traveling speed command so that the packets from respective direction can pass an intersection efficiently; and a traffic signal control means (114) for controlling a traffic signal in conjunction with a packet arriving at the intersection under control of the packet traveling control means. Since the system indicates a speed command to vehicles on the road to make the vehicles travel while forming a packet having the predetermined vehicle train length and the inter-vehicle train distance, unnecessary acceleration/deceleration can be suppressed to thereby not only achieve improvement of fuel consumption and suppression of environmental pollution, but also suppress occurrence of natural traffic jam.
