This paper describes the design and performance of the newly developed Headquarters Traffic Control System (HTCS), which performs the supervision and control of traffic within prefecture-wide areas. The HTCS consists of a headquarters center and city centers, each of which controls traffic signals in a city-wide area and sends data to the headquarters center. The first system has been delivered to the Gunma Prefectural Police Headquarters. The most significant features of the system are simplification and improvement of control logic, resulting in savings of labor maintenance, and enchancement of unattended operation of the city centers. The time-lag problem in the morning peak periods has been solved by adding a predictive control algorithm to the conventional logic. The effectiveness of the system operation has been proved by various data obtained after the installation of the system in April, 1977: reduction of vehicle travel time by as much as 15%, for example.
