Cape Town is testing smart speed signs on some of its busiest roads in a bid to get drivers to slow down. The City has already installed 10 digital speed feedback signs across high-traffic corridors, including High Level Road, Ocean View Drive, Jip de Jager, Main Road, Beach Road and Victoria Road.

The signs track the speed of passing vehicles and display it in real time. When motorists go over the speed limit, the screens prompt them to slow down. The idea is simple: show drivers exactly how fast they are going and encourage an instant change in behaviour.

Early Results Show Fewer Drivers Speeding

According to reports, the first results look promising. On High Level Road in Sea Point, where the first two signs were installed, speeding dropped by 25% after the LED displays were switched on.

Urban Mobility MMC Rob Quintas said the City measures driver behaviour before and after activation. For the first two weeks, the displays stay off while officials gather baseline speed data. Once the signs are switched on, the City tracks whether driving patterns change.

Quintas said officials noticed fewer vehicles breaking the speed limit once the displays became active. He also said monitoring showed drivers braking when they saw their speed and the warning message on screen.

More Communities Want the Signs

It is reported that the first installations began in mid-2023 and interest from communities has grown since then. Requests for more signs have reportedly come from several wards, pointing to growing public support for technology-based traffic calming.

That matters in a city where speeding remains a daily risk for drivers, passengers and pedestrians. Even a small drop in speed can make roads safer, especially in dense urban areas with heavy traffic and frequent pedestrian movement.

AI Cameras are not Part of the Rollout

While Cape Town is exploring tougher tech tools for road enforcement, AI-powered cameras are not being rolled out at this stage. City Traffic Services spokesperson Kevin Jacobs said an AI camera was used on a trial basis to test whether it could help detect offences such as crossing solid white lines, not wearing seatbelts and using cellphones while driving.
