A cellular automata based model for traffic in congested city

This work targets modeling traffic flow in roads of a congested city. The cellular automata (CA) have been configured for such modeling. The urban traffic models, in general, concentrate on low traffic density. The inabilities of traditional models to address the issues arise out of heavy traffic in crowded cities of third world countries are properly addressed in the proposed elementary CA based model. The effectiveness of the model is verified considering the traffic in Kolkata. It is established that the model can fairly reproduce various traffic conditions as found empirically. Further, the proposed model succeeds the limitations of traffic flow models in congestion and also reproduces the empirical results.
