Safety Evaluation of Corner Clearance at Signalized Intersections (Full and TECHBRIEF)
This study evaluates corner clearance at signalized intersections in the State of California and the City of Charlotte, North Carolina. For limited corner clearance on the approach corners, the results indicate statistically significant reductions in total, fatal, and injury, and rear-end crashes. The results also indicated reductions in sideswipe and nighttime crashes, and increases in right-angle and turning crashes. This study suggests that removing access on mainline receiving corners to improve corner clearance-with reasonable assumptions for cost, service life, and the value of a statical life-can be cost effective for reducing crashes at signalized intersections.
