Abstract
This paper focus to study on riding behaviour change, such as speed, brake force and throttle force applied, when they ride across speed hump. The instrumented motorcycle which equipped with various types of sensor, on-board camera and data logger, were used in acquiring the traffic data in this research. Riders were instructed to ride at two speed humps and riding data were then analyzed to study the behaviour change from different riders. The results from statistical analysis showed that the riding characteristics such as speed brake force and throttle force applied are influenced by distance from hump, riding experience and travel mileage of riders. Riders were tend to apply higher brake intensity at distance 50m prior from speed hump and release the braking after distance -10m from hump. Furthermore, riders were found released throttle and applied brake to reach a comfortable speed to cross the hump and accelerate only after the hump crossing. In short, speed hump seems have different rates of influence towards riding behaviour on different factors, such as distance from hump and different riders' attributes.
