| 摘要： | This report is one of the two reports of the project evaluated safety and operations impact right turn followed by U-turn at a signalized intersection as an alternative to direct left turn (DLT) from driveways and side streets. This report evaluated the safety of both alternatives by comparison of traffic conflicts. Nine types of conflicts were selected for this study. Five of the conflicts were related to right turn U-turn (RTUT) movements, while the rest of them were related to DLT movements. Data was collected with the help of video recording equipment at a total of eight sites for over 300 hours. Descriptive analysis and conflict rate analysis was conducted. |
