ALTERNATE PATH ANALYSIS ALGORITHM FOR URBAN FREEWAY CORRIDOR EVALUATION

Quick-response procedures and programmable calculator routines have been of increasing interest in transportation planning. As part of a continuing Highway Planning and Research Program study, the PASSER IV system of quick-response methodologies is being developed for analyzing urban freeway corridor alternatives. This will provide a practical and user-oriented tool to evaluate several classes of transportation system management alternatives. An algorithm is presented for estimating the levels of traffic flow on individual parallel facilities in an urban freeway corridor, based on equilibrium traffic assignments. A quick-response routine for the algorithm has been developed for use with a programmable calculator. The level of detail for the routine is ultramacroscopic and deterministic. The routine was designed to be modular to permit additional scenarios, extensions, and modifications to be easily appended. The routine as described is undergoing continuing revision and evolution.
