Analyzing Crash Frequency by Collision Type at Freeway Diverge Areas

Abstract:

The objective of this study is to analyze the crash frequency by collision type at freeway diverge areas. Three major collision types were identified in this study including rear-end, sideswipe and angle collisions. We compared the crash counts and crash rates by collision type between exit ramp. The data analysis results show that exit ramps with lane-balance design have lower crash frequency and crash rate of rear-end collisions than those not lane-balanced.
