OPTIMAL CONTROL OF ISOLATED TRAFFIC SIGNALS (ABRIDGMENT)

The purpose of the study was to examine the properties of conventional fixed-time (FT) and vehicle-actuated (VA) control of isolated, signalized intersections and to develop and test a self-optimizing control strategy giving special consideration to buses and pedestrians. The project was carried out in five stages involing the following main studies: 1) Criteria for signal control; 2) Literature inventory of control strategies; 3) Development of strategies; 4) Simulation; and 5) Field tests. The results of the studies indicate strongly that the TOL strategy when compared to conventional FT and VA control gives substantial reductions of average delay and proportion of stopped vehicles. Further improvements can be given to the buses if they are weighted higher than the other vehicles. The TOL strategy can also be applied for coordinated signal control of nearby intersections.
