DESIGNING AND TESTING OF TRAFFIC CONTROL

In setting up traffic control for a junction the designer should have the aim to get an optimum within certain limits regarding the safety, the traffic flow, priority and fixed time control. General rules cannot be given. The rules for control are mainly determined by local circumstances, policy making authorities, police considerations and the conceptions of public transport administrators. For the design of such a traffic control the microcomputer can be a good aid, as also for the testing and evaluation of the design. In this article an overview is given of which activities per phase should take place, how far the microcomputer can be used and which software can be used. (TRRL)
