Mauritius Traffic Jams Cost the Economy Up to Rs 6bn a Year

Traffic congestion in Mauritius is no longer just a daily frustration. It has become a measurable drag on the national economy, with estimates placing its annual cost anywhere between Rs 2 billion and Rs 6 billion, depending on the study and the period assessed.

That wide range reflects a significant gap in official data. There is currently no recent, nationally recognised figure for the full economic cost of road congestion in Mauritius. The estimates that do exist come from separate studies conducted at different points in time, using different methodologies, which makes direct comparisons difficult.

What is consistent across all assessments is the direction of the problem: congestion is getting worse, and its economic consequences are growing. The costs fall into several overlapping categories. Lost productive time is the most obvious, as workers and business owners spend hours in traffic each week that could otherwise be spent working. Fuel wasted in slow-moving or stationary traffic adds directly to household and business expenses. Vehicles operating in stop-start conditions also wear out faster, increasing maintenance costs. For businesses that rely on deliveries or time-sensitive logistics, delays translate directly into lost revenue and unreliable supply chains.

Mauritius has one of the highest vehicle-to-population ratios in Africa and the Indian Ocean region. The island's road network, particularly around the capital Port Louis and the busy M1 motorway corridor connecting the north and south of the island, regularly experiences severe congestion during morning and evening peak hours. The problem extends to secondary routes as commuters seek alternatives, spreading delays across a wider area.

Public transport has long been proposed as part of the solution. The Metro Express light rail, which links Port Louis to Curepipe via Rose Hill and Quatre Bornes, was introduced to offer a faster alternative to road travel in the busiest central corridor. Ridership has grown since its launch, but road congestion has not eased significantly, partly because car ownership continues to rise and partly because the network does not yet cover the full range of commuter routes.

What this means for residents and the broader economy is straightforward. Every hour lost in traffic is an hour not spent working, with family, or contributing to business activity. For lower-income workers who cannot choose their hours or work remotely, the burden is proportionally heavier. For the economy as a whole, the cumulative effect of billions of rupees in lost output and wasted fuel represents a structural inefficiency that weighs on competitiveness.

Without a current, government-commissioned study establishing a definitive national figure, policymakers are working with incomplete data. Closing that information gap would be a first step toward designing congestion measures that are properly costed and evidence-based.
