SIMULATION OF MIXED VEHICULAR TRAFFIC ON A TWO LANE HIGHWAY.

Traffic flow is stochastic in nature, the free speeds are probabilistic and the process is affected by logical decisions concerning acceleration, retardation, overtaking etc. Analytic techniques of traffic flow theory are suitable for the analysis of homogeneous vehicular traffic. Computer simulation is adopted in this study to analyze the mixed traffic flow. A simulation model which includes unimpeded, overtaking and restrained stream logics is formulated using field data. Parameters of the model are estimated and the simulation model is validated. The study indicates that a nonlinear interaction between different categories of vehicles in mixed traffic flow can be analyzed by simulation.
