The 2001 project for FDOT evaluated the safety and operational impacts of two alternative lef-turn treatments from driveways/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.
The results indicated that safety was great for right turns followed by U-turns than for direct left turns.
