THE VALUE OF FIXED-TIME SIGNAL CO-ORDINATION IN DEVELOPING COUNTRIES. II. IMPROVED BUS MODELING AND RESULTS

This paper addresses the issue of explicitly adapting the model in TRANSYT to the traffic conditions in a network in Santiago, Chile. It is believed that the main source of differences between European traffic conditions and those in Chile is the presence of a large number of unregulated buses. The research reported here confirmed this assumption and developed an improved approach. This resulted in an enhanced link structure, a redefinition of some basic measures like saturation flow and cruise times, and a recalibration of the platoon dispersion parameters in TRANSYT. This additional effort produced considerable improvements in performance, more than doubling the benefits of plans prepared with more conventional TRANSYT values. A complete statistical analysis of these results completes this paper.
