VARIABLE SPEED LIMIT CONTROL SYSTEM

摘要

PURPOSE: A variable speed control system is provided to control the speed of following vehicles and to maintain stable traffic flow. CONSTITUTION: Multiple traffic information gathering parts are installed in a road at regular intervals. The multiple gathering traffic information parts measure the traffic information of vehicles. An operation processing unit(221) computes the average velocity of the vehicles based on the traffic information. A control part(222) reprocesses the average velocity. Multiple variable message board(230) displays the reprocessed average velocity value.
