In this paper, an approach used in developing and validating a simulation model for studying the heterogeneous traffic is presented. As part of the model development, longitudinal and lateral updating procedures for the vehicular movement have been discussed in detail. Vehicle movement patterns on mid-block sections are studied and utilized this information as input for developing the vehicle updating procedures. This model is validated at macroscopic level for both urban and rural heterogeneous traffic conditions. A methodology adopted for collecting the macroscopic data from the simulation model using “cell” as a unit of vehicle is presented. Using flow-occupancy relationships in terms of cells, utility of this methodology in analyzing the heterogeneous traffic is presented. Traffic observed on urban and rural mid-block road sections has been studied using this model.
