The Proper Bus Stop Location from an Intersection Considering Traffic Safety


Record Type:Component

Order URL:http://amonline.trb.org/



Washington, DC 20001 USA

Abstract:Too many bus stops are indiscriminately installed from an intersection. This study aims to suggest the most efficient distance that supports bus stop operations taking traffic safety into account. In order to estimate the proper bus stop location distance to an intersection, this study collected data of vehicle vs. vehicle and pedestrian vs. vehicle accidents that occurred near bus stops. Many variables such as traffic volume and bus stop location were also included. This data was then used to conduct correlation analysis to assess if any relationship existed between traffic accidents and bus stop location. These results helped in developing a traffic accident prediction model which divided vehicle vs. vehicle accidents, and pedestrian vs. vehicle accidents. The objective function equation was derived from these models that minimized the total number of traffic accidents in order to estimate the proper bus stop location distance to the intersection curb through the optimization technique.
