Safety Evaluation of Right Turns Followed by U-Turns as an Alternative to DirectLeft Turns: Crash Data Analysis. Volume 1

摘要

This project evaluated the safety and operational impacts of two alternative left-turn treatments from driveway/side streets. The two treatments were: (1) direct left turns and, (2) right turns followed by U-turns. Safety analyses of the alternatives were conducted using two major approaches: traffic crash data analysis and conflict analysis. Findings related to the crash data analysis are documented in this report. Two other reports document the conflict and operational analyses.
