In order to select a model for application in Ontario's freeway-arterial corridors, a review of potential candidates was performed. The criteria for evaluating suitable alternatives included the quality of the path selection technique, the ability to represent dynamic queueing effects, the accuracy and detail of the traffic flow model, and the resolution of the traffic signal representation on parallel arterials. The following models were initially considered: MACK, FREFLO, FRECON, INTRAS, TRAFFICQ, FREQ, CORQ, CORCON, SCOT, TRAFLO, DYNEV, CONTRAM, SATURN, and MICRO-ASSIGNMENT. On the basis of a literature review and a preliminary evaluation of fundamental requirements, some of these initial models were found to be clearly incompatible with the objective of modeling dynamic assignment and queueing in freeway-arterial corridors. Of the remaining models, which included FREQ, CORQ, TRAFLO, DYNEV, CONTRAM, and SATURN, none could fully satisfy all major criteria. However, it appeared that some could potentially be upgraded, given that a considerable amount of further development effort was applied. In this respect, CONTRAM and CORQ appeared most promising because of their superior queueing-based assignment techniques and their treatment of time varying queues and demands.
