SYSTEM FOR TRAFFIC REGULATION Russian patent published in 1999 - IPC

FIELD: road equipment. SUBSTANCE: device has central computer which gathers information about traffic conditions which are read by video cameras which are mounted by road. Motor transport vehicles are equipped with computer which are connected to central computer by radio link for exchange on signals about traffic conditions for visual displaying of received data which contain information about traffic jams, theirs causes, duration and optimal route to reach destination. Load of central computer is decreased by regional base computers which are located in various districts of city and which inputs are connected to separate groups of video cameras and outputs are connected to input of central computer. Electric circuits between outputs of video cameras which are located by traffic lights and inputs of base computers are equipped with switching assemblies which input is connected to electric circuit for turning green light of traffic lights on through timer which delays arrival of signal for time required for acceleration. EFFECT: increased functional capabilities, decreased cost for manufacturing, development and operations. 5 cl, 4 dwg
