Abstract

Speeding problem in certain area has become a major concern by the public. Many accident have been reported involving pedestrians because of excessive speeding vehicles. Hence, the local road authorities take the initiative to install traffic calming devices to reduce the problems that have been arise. Basically, this study attempt to find out the ways to improve the usage of traffic calming devices so that it can be more effective in future. One of the most effective traffic calming devices that usually been used by local road authorities for vertical deflection is known as speed hump or speed bump. Presently, there a lot of speed humps have been installed on the road to counter the problem relating to traffic volume and traffic speed. So far in Malaysia, there are various types of speed humps on the road with no special guidelines about the actual distance between speed humps to achieve the desired maximum speed. Thus, the focus of this study is to investigate the effect of separation distance between speed humps on the speed of travelling vehicles. Actually, the main aim is to identify various types of speed humps and to establish the relationship between speed of travelling vehicles at midpoint and separation distance between speed humps. This relationship will help the local road authorities to control the maximum speed of vehicles on road by increasing or decreasing the separation distance. In this study, 10 sites have been chosen at residential area and school area with different separation distances between speed humps (17m to 220m) by using google maps. All the data collected include all types of vehicles except motorcycles, bus and lorry. Data analysis has been performed for 85th percentile speeds and mean speeds. Both speeds are used to develop a graph of speed profile between midpoint speeds and separation distance of speed humps. This graph can be helpful for local road authorities or traffic engineers to decide adequate separation distance of speed humps.
