Abstract
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.
