AN ECONOMIC ANALYSIS OF A HYBRID TRAFFIC CONTROL SYSTEM USING RUNCOST

The computer program "Runcost" was used for an economic analysis of traffic operations on a street network in Charleston, South Carolina before and after the installation of a Hybrid Traffic Control System. Speed and delay data were used as input data for "Runcost", which computes the cost of a speed and delay run for an average vehicle utilizing vehicle operating cost tables from Winfrey's text, Economic Analysis for Highways. The greatest magnitude of savings to the road user resulted from reduced operating costs due to speed changes and stops and in user time savings. Network travel speeds increased 21 percent in the after period while network running speeds increased 12.2 percent. The network running speed for the before period corresponded favorably to the network travel speed in the after period. The total annual network savings to the network users were $613,191 due to reduce vehicle operating costs and $4,676,421 due to reduced personal time while travelling on the network. The capital outlay for the Hybrid Traffic Control System was approximately $550,000. Driver comfort and convenience, traffic accident costs and reductions in pollution due to increased vehicle operating economies were not included in this analysis. /Author/
