Urban Public Transit Systems Modeling Capabilities

摘要

A former assessment of current transit and HOV modeling capabilities wasconducted, 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, LATM, MICRO-ASSIGNMENT, NETSIM, SATURN, TRAFFICQ, and TRANSYT. SATURN and CORFLO were the 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 capabilities.
