Abstract

The optimization of signal timing in a traffic network involves finding the timing plan that optimizes the overall performance in the network. In theory, the network closure constraints limit the performance on individual arteries of the network. Thus networkwide optimization has the potential of imposing some cost or penalty, or both, to individual arterials in the network. The objective of this study was to determine how or if the network closure constraint affects or limits arterial performance in the program for maximum-bandwidth, MAXBAND, and in the program for minimum stops, delay, and fuel consumption, TRANSYT-7F. The results of this study show that for small and medium-sized closed networks, optimization of an entire network using MAXBAND or TRANSYT-7F costs very little in terms of stops, delay, and green bandwidth on the arteries within the network. The added cost associated with the additional stops and delays resulting from networkwide optimization can be expected to impose approximately a 5 percent penalty on individual arteries within the network.
