Choose a speed hump for areas that will require emergency vehicle access. The wider design of a speed hump makes them a highly effective traffic calming device where emergency vehicles and public transport vehicles are concerned.
Because speed humps are more gradual than a speed ramp they are less severe on vehicles. This allows traffic to flow quite normally while slowing vehicles down to a relatively safe speed.
Consider using a speed cushion to futher reduce the effect on emergency vehicles. Cushions will allow for gaps where emergency vehicles can pass through with ease.
A speed table can also be used in urban settings and provide a dual purpose on roads. Use as a highly effective speed reduction ramp and a pedestrian crossing in public roads and streets.
