Study of Motorcycle Rider Casualties at Signalized and Unsignalized Intersections

Abstract

Road crashes have been a significant contributory in fatal and serious injuries. Moreover, motorcycle injuries are one of the top causes of road crash death. The main objective of this study is to improve safety of motorcycle riders at intersections using indirect approach. With this, intersection designs can be improved to achieve minimal casualties and safer roads by conducting studies on factors affecting intersection safety. For this study, traffic signal change and clearance interval, stopping and intersection sight distance were evaluated. Each of these was conducted to find relationship with one another and the collisions that occurred on the selected intersections. Using traffic conflict analysis, the study revealed significant relationships between hourly traffic volume and traffic conflicts such as slow vehicle-same direction, lane change, and rear-end, and total number of road crashes.
