This study investigates influential areas of motorized and non-motorized (pedestrian and bike) crashes at intersections. An influential area of an intersection is typically specified by a radius from the center of the intersection. Practitioners have applied the radius when gathering crash data for their traffic safety analyses. However, there has not been much effort in investigating if the range is appropriate and multiple radii have been applied to intersection safety studies due to the lack of analytical studies on the influence ranges. This research investigates the most probable influence ranges for both motorized and non-motorized crashes by analyzing distributions of crash locations. The result analyzed from 148 intersections in Michigan cities reveals 137 feet and 240 feet as influence ranges for non-motorized and motorized crashes, respectively.

This paper was sponsored by TRB committee ANB20 Safety Data, Analysis and Evaluation. Alternate title: Influential Range for Analyzing Motorized and Nonmotorized Crashes at Intersections.
