THE PLESSEY T200 MICROPROCESSOR TRAFFIC SIGNAL CONTROLLER. SINO-BRITISH HIGHWAYS AND URBAN TRAFFIC CONFERENCE. PAPERS PRESENTED AT THE CONFERENCE HELD IN BEIJING 17TH-22ND NOVEMBER 1986

This paper gives some details of the Plessey T200 traffic signal controller, including its specification, and outlines some of the facilities that it provides. It concentrates on the 'designed in' facilities that include: (1) manual operation; (2) fixed time operation; (3) vehicle actuated operation; (4) cableless linking operation; (5) computer controlled operation. These facilities are used to check that conflicting traffic streams can cross and merge safely, but it is important to realise that most traffic engineering requirements for junction control can be configured into the controller. The T200 controller was designed around but not limited to the requirements of the Department of Transport'S specification mce 0141, which is concerned with the increasingly complex control requirements and traffic facilities arising from modern traffic signal control. Experience with the controller illustrates the advantages of using a powerful microprocessor as the basic control element. A further advantage is that the controller can store a vast amount of data, which traffic and maintenance engineers can access and analyse later, using portable equipment that is simple to operate.
