METHODS FOR TRAFFIC ACTUATED CONTROL OF TRAFFIC SIGNALS

STYRNING AV TRAFIKSIGNALER

The main purpose was to develop and test methods for traffic actuated control of isolated signalized intersections. A discussion of the possible application of the methods developed for coordinated signal control is included. The project was carried out in the following stages: criteria for signal control, literature inventory of control strategies, development of strategies, simulation, field tests. It is found that the theoretical background for fixed-time signal timing can to some extent be applied even for vehicle-actuated (Va) signal timing. Va-controllers can be rebuilt and together with equipment for selective bus detection perform active bus priority (vab). The average bus delay can be reduced by 20%. Traffic-actuated control with optimization logic (tol) for minimization of operating costs can reduce bus delay by 40% and average vehicle delay by 25% as compared to Va. Both vab and tol show high benefit-cost-ratios and are found profitable. This report is in two parts. /TRRL/
