In Japan, a traffic control system (TCS) utilizing a computer for centralized control of traffic signals commenced its operation for the first time in 1966. All the traffic control systems of this type have since then been modified several times and have contributed to the securement of safe and smooth road traffic. However, along with an increase in the traffic demand in recent years, the number of traffic congestion occurrences and the number of traffic accidents have been on the rapid increase and this matter has become one of the grave social problems.
As measures to cope with such traffic situations, strenuous efforts are being made by the police authorities to complete various traffic information provision functions which are aimed at the spatial distribution of traffic flow through the aggressive provision of traffic information to the road users on wheel.
As part of such efforts, the Osaka Prefectural Police Headquarters has completed the construction of a system which automatically provides drivers with information on traffic congestion, traffic accidents, travel time, etc. This system furnishes such traffic information on major ordinary roads and expressways in the form of a map or human voice through the medium of facsimile machines or telephones, respectively.
This paper describes the configuration, functions, and the effect of this automatic traffic information provision system and at the same time reports to you the traffic information provision operations in the traffic control system of the Osaka Prefectural Police HQ.
