  • Abstract:
    Current national transportation policy places increasing emphasis on multi-modal ; solutions involving public transit and high-occupancy vehicle (HOV) facilities ; and services. Current traffic simulation/assignment models, however, have only ; limited capabilities for evaluating the fuel consumption, traffic, and ; environmental impacts of alternative transit and HOV facilities and services in ; a multimodal transportation system. Therefore, a formal assessment of current ; transit and HOV modeling capabilities was conducted, with emphasis on CORFLO, ; which is uniquely suited among U.S. public-domain models for detailed evaluations ; of traffic conditions in urban corridors. Other models assessed include CONTRAM, ; INTEGRATION, JAM, TATM, MICRO ASSIGNMENT, NETSIM, SATURN, TRAFFICQ, and TRANSYT. ; SATURN and CORFLO were teh most highly rated with respect to their modeling ; approach, transit and HOV supply/demand modeling, and output measures of ; effectiveness. A detailed analysis of CORFLO's logic and code and a case study ; evaluation of transit and HOV alternatives using a CORFLO model of the North ; Central Expressway Corridor in Dallas, Texas, revealed several areas in which ; CORFLO should be enhanced to improve its urban public transit systems modeling ; capabilites. Recommended enhancements include increasing the number of bus ; stops that can be accommodated, refining the modeling of bus movements along ; links, and adding or improving fuel consumption and emissions algorithms. These ; enhancements are necessary in order to estimate with reasonable accuracy the ; fuel consumption, traffic, and environmental impacts of common transit and HOV ; alternatives.
