Abstract

Abstract: Traffic flow modelling is defined as the mathematical description of the complex traffic flow system for characterizing and predicting the behaviour of traffic. Traffic stream models are the basic building blocks of many of the traffic flow models. Traffic stream models identify the underlying relationships among the three basic traffic flow variables, speed, flow and density. Knowledge of traffic flow variables and their interrelationships and ways to model traffic are essential in the planning, design and operation of transportation systems. When designing roads, parameters from the international literature are used, containing values derived empirically from local data on traffic flow (mostly from northern American cities). Also many models have been developed for the homogeneous traffic conditions, but no such models have been developed for the extremely heterogeneous traffic conditions like that in India. Many studies have been conducted on the methods of developing models for heterogeneous traffic but a well- recognised model has not been developed for the heterogeneous traffic like that in India. Through our study we aim to develop such a model for the heterogeneous traffic on the National Highways in India. We developed different types of relations between speed and density (like linear, quadratic, exponential and logarithmic) and then proposed the model that was most suitable for the traffic on the Indian National Highways. We found out that the relation between traffic speed and traffic density is quadratic and the path followed by the curve is parabolic in nature. We also have developed models for different types of vehicles separately and then converted the traffic into their corresponding PCU values and then formulated the models again. To reach our goal we conducted traffic survey on the National Highways and from the recorded data we developed the models for National Highways. From our study, it was found out that the flow and density of the traffic on the National Highways was low while the traffic speed was found out be high. In fact, the free flow speed of the vehicles is low and can be attained with much ease. After the validation of our models, we found out that there was minimum error in our models.
