Mean Delay Modelling for Indisciplined Traffic

Modelling the complex process of vehicle movement at a signalized traffic intersection has been a very challenging avenue in the stochastic modelling approach of transportation research. This already complicated problem becomes further involved if one accounts for the problem of vehicle overtaking . However, in developing countries like India, there is a dire need to address traffic control problems involving such indiciplined traffic. In my Masters, I had the opportunity to work in this exciting topic, where we could address the key question of mean delay modelling of vehicles in such a traffic intersection. We analyzed the mean delay using a simple modelling construct of decomposing the queue of indisciplined vehicles into an assembly queue, forming vehicle batches, followed by an interrupted intersection queue, where the vehicles wait until they leave the intersection. An approximate analysis of this preliminary principled approach turned out to produce remarkably close approximations to the actual delay obtained from simulations.
