• 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.
