This paper analyses options for reducing congestion along a section of the motorway in Mauritius of length 7.56 km. The section consists of 6 roundabouts and is heavily congested during the afternoon peak hours. Using Traffic Cellular Automata, we first model the impact of substituting either one of the roundabouts with a flyover bridge and find that the congestion level remains unchanged. Furthermore, we find that even if one roundabout is present, the congestion level will still remain unchanged. The only solution is to substitute all the roundabouts by flyover bridges that would allow uninterrupted traffic flow. Besides we find that the number of possible rear-end crashes would also be significantly reduced.
Keywords: Congestion, Rear-end Crashes, Traffic Cellular Automata
