Integrated macroscopic modelling for describing flow on the freeway and its components is presented. Based on this modelling, an interactive menu-driven macroscopic freeway simulation program with graphic capabilities was developed and is presented in this paper. The program was tested against simulated and actual databases and it was adjusted accordingly. Input requirements are conventional traffic parameters, freeway and ramp characteristics, demands and geometric information. Output includes estimation of delays, stops, energy consumption, pollution levels and other important measures of effectiveness. In addition two- and three-dimensional plots of speed, flow and density are produced for dynamic description of these basic variables operation during the simulation as well as description of the input information in a graphical form.
