Safe Following Distances for Motorcycle to Prevent Rear-end Collision

S. Sitthiracha, S. Koetniyom


Rear-end collision is one of the top accidents for the motorcycle in ASEAN countries because the motorcyclists always keep their following distances too short. There are no specific safe distances suggested for motorcycle especially in an emergency braking situation. This study proposed a model based on the piecewise linear model of motorcycle braking deceleration profile and kinematic equations for calculating the stopping distances in a worst-case scenario. The calculated results were compared to the braking experiment and test results from other studies. The information from this study can be useful to relevant authorities such as driving institutes and enforcement agencies in order to setup a safety measure for the motorcyclists.
