Abstract
Speed humps are one of the traffic calming measures widely accepted to control vehicle speed in the local
road. Humps standards from the western countries are designed mainly for the passenger car. This study,
therefore, aims to reveal the effectiveness of speed hump to control the motorcycle speed. This study
observes the free-flow speed of the riders at the total of 20 speed bumps and humps. They are 0.3-14.8
meter in width and 5-18 centimeter in height. The results reveal that the 85th percentile speeds reduce 15-65
percent when crossing the speed bumps and speed humps. Besides, this study develops the speed model
to predict the motorcycle mean speed and 85th percentile speed. It is found that speed humps follow the ITE
standard can control motorcycle crossing speeds to be 25-30 Kph which are suitable to travel on the local
road.
