The Effect of Road Hump in Reducing Speed of Motorcars in a Residential Area in Kuala Lumpur [PDF]

open access: yesJournal of Design and the Built Environment, 2013
In its most simple terms, traffic calming is about preserving the functions of local streets. As local streets are intended to provide primarily land-access services, hence, when traffic begins to use local streets for through movements, traffic volume ...
