Abstract
This paper aims at analyzing three different solutions suggested for traffic congestion relief in Port Louis, the busiest city of Mauritius. It evaluates the impact of the three alternatives which are the use of Light Rail Transit (LRT) as an alternative mode of transport, the construction of a Ring road around Port Louis, and the upgrading of the current bus network into a Bus Rapid Transit (BRT) system. The impact of these three solutions has been evaluated by performing Traffic Cellular Automata (TCA) simulations. Our studies reveal that the Ring road will lead to more congestion while introducing the LRT or upgrading the current bus network will reduce congestion significantly.

Summary
Traffic congestion is a condition on road networks which occurs as their use increases. It is characterized by slower speeds, longer trip times, and increased vehicular queuing. Mauritius is an island located in the Indian Ocean with a land area of 1865 km[2]. The total road length on the island is of 2066 km. Increased congestion implies increased emission of Greenhouse gases GHG. In 2010, 1323.8 thousand tons of GHG was emitted by the transport sector in Mauritius out of which 1261.2 thousand tons consisted of CO2. The transport sector contributes 31.9% of the total CO2 emission in Mauritius. Congestion is common in both the rural and urban parts of the island. The Curepipe-Port Louis corridor, which accounts for nearly one-third of trips, remains the segment of greatest concern
