COMPARATIVE STUDY OF DESIGN AND PLANNING PROCESS OF TRAFFIC CALMING DEVICES

Abstract: Speeding traffic on neighborhood streets and high through traffic volume affects the safety and quality of residents lives resulting in a loss of amenity for residents. Traffic calming is a way to design streets using physical measures to control the dominance and South Africa have sophisticated and organized methods to carry out the whole process. While most of the Asian countries as Japan does not have well defined and systematic study process to facilitate traffic calming process. This paper discusses about a comparative study of traffic calming device design guidelines, decision making process, installation policy, and the evaluation of effectiveness of a few of the most popular traffic calming devices. A before and after study of traffic speed, accident, traffic flow, environmental aspects and residents ’ reaction were performed to evaluate the impacts of traffic calming devices.
