In developing nations like India, majority of the urban roads are bi-directional in nature consisting of wide varieties of vehicles which follow weak lane discipline. The vehicular manoeuvers on such roads are complex due to higher lateral interaction between the vehicles moving in both directions. Analysis of such behaviour with the help of mathematical or analytical approach may not be so efficient. Hence, simulation has become an inevitable tool for analysis and interpretation of such complex vehicular interactions. Only few attempts have been made to model such traffic flow considering both longitudinal and lateral behaviour of vehicles. In the present study, an attempt has been made to develop a microscopic simulation model for mixed traffic on urban undivided roads using object oriented programming concepts. Influence area concept is used to identify the most influencing leader vehicle (including non-overlapping leader) which affects the vehicular manoeuvers on these roads. The developed model is calibrated and validated using real world traffic data collected from two different cities located in Southern India. The developed model will be helpful for traffic engineers to experiment with different design configurations, control strategies and traffic flow conditions, and determine their impacts on the system.
