30km/h

The implementation of 30km/h speed zones, particularly in dense urban areas with high pedestrian activity such as near schools and residential neighbourhoods, is a proven strategy aimed at enhancing road safety. By reducing vehicle speeds to 30 km/h (approximately 20 mph), these zones mitigate the risk of severe accidents, particularly for vulnerable road users like children. Empirical studies indicate that lower speeds provide drivers with increased reaction time to respond to sudden pedestrian movements. Furthermore, the severity of injuries or fatalities resulting from collisions is significantly reduced at these lower speeds, making it an effective intervention in promoting road safety.

Globally, CHI partners have advocated for the adoption of 30km/h zones, which has been associated with a measurable reduction in pedestrian fatalities and injuries, particularly in urban areas with high traffic density. The evidence overwhelmingly suggests that 30km/h speed zones are a critical tool in minimising road safety risks. In addition to their safety benefits, these zones also create a more pedestrian-friendly environment, encouraging walking and cycling among children, thereby contributing to broader public health goals, and promoting sustainable urban mobility.
