Speed Control on the Highway with Speed Hump

Abstract

This article is related of traffic calming device by installing speed hump was found to inform people the potential of speed hump about not only how it can control vehicle speed and what is the main criterion in design, but also depict some problem occurring when we use speed hump in the field. The procedure for installation begins with the residents’ request and continues with traffic engineering studies to determine the need for speed hump. These studies include but are not limited to: safe sight distance, pedestrian studies, vehicle classification, traffic count, and average speed. “as built” plans, other control devices, and stop sign compliance should also be examined. If it is determined that speed humps are the best solution for a roadway, then the installation can begin. The humps installed should follow the design criteria. They should be 4 meter (12 feet) long and 8-10 centimeter (3-4 inches) high, have accompanying warming signs in accordance with manual on Uniform Traffic Control Devices (MUTCD) and be painted with a pattern that makes them visible to drivers and provide a safe reasonable sight distance. If designed, installed, and maintained properly, speed humps can be a safe, effective method of reducing vehicle speeds through residential areas.
