MCDOT: Run-Off Road Crash Evaluation
|
YSMA evaluated 18 Run-Off-Road crash locations for Maricopa County DOT, that had a history of Severe crashes.
We analyzed crash data and evaluated surrounding roadway conditions during daylight and darkness to identify crashes that are susceptible to correction due to roadway improvements. Several short-term and long-term countermeasures were identified including removal of features encroaching in clear zones. The short-term recommendations included removal of power poles, delineate drainage structures, signing and striping improvements, and guardrail installations. The suggested long term improvements included extending culvert crossings, realignment of horizontal and vertical curves, etc. |
