FREEVU (Freeway Evaluation with Visual Understanding) is a personal computer simulation model intended for freeway design and analysis. It allows the user to specify a freeway section, including lanes, grades, exits and entrances, posted speed limits, and detector locations. The section can then be viewed to confirm the proposed design. A variety of traffic situations can be specified, including percentage trucks, distribution of car and driver characteristics, and entrance and exit percentages. The user can simulate the traffic situation for various freeway design alternatives and then evaluate the design through two methods. First, the information from the specified detector locations can be used to evaluate average volumes, speeds, and densities over time. Second, an animation of the simulation results can be viewed to evaluate weaving sections, stability of traffic flow, impacts of trucks, and so forth. The model is a descendent of the simulation models INTRAS and FOMIS. As in these two models, vehicle movement is based on classic car-following theory and collision-avoidance restrictions. However, FREEVU also incorporates behavioral lane changing algorithms and vehicle performance constraints. FREEVU is user-friendly with extensive menus and default values. The simulation model has been evaluated using different sites and was generally found to represent simulation traffic flow accurately.
