| 摘要： | U-turn lanes are commonly provided at diamond interchanges to reduce delay for U-turning traffic and for the interchange as a whole; however, there are currently many unknowns related to their design, operation, and use. Project 0-6894 was tasked with identifying and investigating demand and capacity factors affecting U-turn lane use, determining the performance of U-turn lanes under various geometric and operational conditions, and determining the anticipated effectiveness of proposed solutions to U-turn operational issues. This project also provides a cross-sectional safety analysis of existing U-turn configurations. |
