The subject of this paper is the application of a feed-forward strategy to isolated intersection traffic controllers. The criterion uses the fact that vehicles approaching an intersection are detected far away from the intersection. This information is then fed to a microprocessor which in turn can develop its control policy long before the vehicles arrive at the intersection such that the results are related to the vehicles that the intersection is currently serving. A special program is developed and tested utilising the intel 8080 microprocessor. The program is tested on a simulated symmetrical intersection. The results of various tests showed a marginal improvement over normal vehicle-actuated signals when traffic was unsaturated. (Author/TRRL)
