TRAFLO: A NEW TOOL TO EVALUATE TRANSPORTATION SYSTEM MANAGEMENT STRATEGIES

The TRAFLO model, which combines the attributes of traffic simulation with traffic assignment, is described. TRAFLO was developed as a tool for use in transportation planning and traffic engineering to test transportation management strategies. It is a software system, programmed in FORTRAN, that consists of five component models that interface with one another to form an integrated system. Four of the models simulate traffic operations, and the fifth is an equilibrium traffic assignment model. The operating characteristics of the component simulation models are described. These models are capable of simulating traffic on one or more of the following networks: freeways, corridors that include the freeway/ramp/service-road complex, urban and suburban arterials, and grid networks representing the central business districts of urban centers. Also described is the traffic assignment component, which can be used in conjunction with the simulation components to determine the response of a traffic system to a transportation management strategy.
