| 摘要： | Historically, engineers have designed intersections characterized by sizeable right-turn volumes using a variety of strategies. For example, channelization in the form of a painted island, small raised island, or a large raised island is one element often incorporated into the design. In addition, traffic control may be addressed using right-turn-on-red, dedicated turn lanes with stop control, or dedicated turn lanes with yield control. This paper focuses on how Cobb County, Georgia, located in the metro-Atlanta area, handles these right-turn movements. The study identifies application of various right-turn strategies based on observed field operation conditions. A comparative analysis of applications based on a two-year crash history helps to identify (preliminarily) possible safety limitations associated with the various right-turn strategies. The primary objective of this study is to share considerations, strategies, and limitations of the various right-turn configurations and to identify strategies appropriate for further in-depth analysis. |
