Traffic congestion is of great concern for the inhabitants of Dhaka city because of elongated travel time, loss of productive hours. Despite of all the planning programs and projects designed by the government, the outrageous congestion problem is worsening day by day because of the rapid growth of population and increase in the number of vehicles. The traffic simulation model provides the option to simulate a real project in the computer and observe its impacts prior to the implementation. However, these available simulation models are not suitable for simulating heterogeneous non-lane based mixed traffic. For these reasons, the author has developed a simulation model using the OOP tool. The author has coded the road network and all of its components and characteristics in Java because of its multithreading, high performing capacity, more natural, logical, secure, architecture-neutral, portable and dynamic characteristics. The simulation model developed by the author is capable of determining fundamental traffic flow characteristics such as flow rate, average speed and density and their relations. The model has been calibrated and validated against the field data. However, the simulation results have been verified with the available traffic flow models and found satisfactory.
