Worldwide, the transportatio
n problems faced by various nations have increased manifold,
necessitating search for methods or alternatives that ensure efficient, reliable and faster means
of transport. This is all the more true in a country like Mauritius, where in the population is
i
ncreasing significantly. The urban areas in Mauritius are the most affected by traffic problems.


Port
-
Louis being a hub of commercial and business activity is facing ever
-
increasing vehicular
traffic. This has resulted in multifaceted traffic problems su
ch a accidents and peak hour
congestion. The current level of traffic congestion, particularly during the peak hours and in the
urban corridor between Curepipe and Port
-
Louis has become virtually unmanageable. Daily,
millions of rupees are lost due to vehi
cles burning extra fuel as a result of being trapped in
traffic congestions. The major cause of this deteriorating transport conditions was identified as
being primarily due to the increasing ownership and use of private transport. The country
registered i
n the last decade an increase faster than usual of the fleet of private cars and
minibuses. Our current road network is unable to cope with the existing levels of traffic.


One of the ways to alleviate the problems faced is to modify the actual road netwo
rk. Road
traffic simulation provides an adequate tool for the assessment of the impact on the congestion
level of different changes that can be brought to the road network topology. Traffic flow models
are categorized into three classes: macroscopic, micro
scopic, and mesoscopic models. These
models are contrasted based on the level of detail they present in modeling the granularity of
traffic flow. Macroscopic models consider traffic flow in an aggregated way as a fluid process.
Unlike macroscopic models, m
icroscopic models consider interactions between individual
vehicles in a traffic stream. Traffic Cellular Automata (TCA) are efficient microscopic traffic flow
models.


The aim of this paper is to analyse the impact of changes to the road network by using

TCA.
TCA models arise from the physics discipline of statistical mechanics, having the goal of
reproducing the correct macroscopic behaviour based on a minimal description of microscopic
interactions.
