THE roads department has fitted three rows of flat-topped solid rubber speed bumps of 60mm height across Walmer Boulevard. My understanding of speed bumps is they are to control vehicles to the speed limit, not reduce the speed well below the limit.
The traffic calming bumps fitted, if approached at 60km/h, will damage/destruct the average small car in time, the bumps are so severe. This road is used by many emergency vehicles like the fire department, ambulances, police, etc – their reaction time will now be increased as most vehicles cross the speed bumps at 20 to 30km/h.
The noise pollution for the residents of the vehicles slowing down, well below the speed limit, before crossing the speed bumps with a rumble noise and then the accelerating of the vehicles is incredible.
The design of these solid rubber speed bumps is most suitable to shopping complexes, car parks, hotel and townhouse complexes etc (see rubberspeedbumps.co.za). The alternatives should have been robots positioned on the intersection of Walmer Boulevard and Pier Street or a permanent speed camera, which would bring in much needed revenue for the municipality.
