Abstract

Currently, pre-timed and actuated signal controls are widely used at most signalized intersections. Adaptive signal controls are not widely used due to uncertainties regarding their benefits. This paper investigates the optimization and consequential benefits that can be achieved through the use of pre-timed, actuated and adaptive signal controls through a systematic simulation study. Traffic variables such as signal delays, level of service, volumes, capacities, directional mix, mid-block flows, degree of randomness of arrivals and turning movements are examined to determine their impact on the potential benefits. The macroscopic and microscopic simulation models such as Emme/2, INTEGRATION, Synchro and Sim-Traffic are used to carry out simulation and analysis for a 3x3 arterial network of 9 intersections. It is concluded that the optimization significantly improves the performance of pre-timed, actuated and adaptive signal controls, and further that adaptive signal control performs better than the pre-timed signal control and is comparable or better than the actuated signal control for the arterial network.
