An interactive menu-driven macroscopic freeway simulation program with graphic capabilities is presented. The program is written in UCSD-Pascal language and runs on IBM personal computers. Recently developed flow models that describe complex phenomena such as lane changing, merging, and weaving are employed. The computational effort is minimized by using fast and efficient numerical methods for implementing these models. Input to the program is conventional traffic parameters, freeway and ramp characteristics (e.g., capacity, free-flow speed, jam density), demands, and origin-destination information. Output includes dynamic description of speed, flow, and density (both numerical and graphic); estimation of the most common measures of effectiveness; and graphic representation of flow conditions and congestion levels.
