Abstract:

This study is to investigate safety issues in the design of dual right-turn lanes. Historical crash records at 19 dual right-turn lanes were collected and analyzed to identify the contributing factors to different types of right-turn related crashes. In addition, the historical crash records for the dual right-turn lanes were compared to those for single right-turn lanes with similar traffic conditions. Based on the results of this study, several issues in the design of dual right-turn lanes were identified and recommendations for improvements were provided. It was found that dual right-turn lanes that are well designed do not cause more crashes than single right-turn lanes. This study can help traffic engineers to better design and implement dual right-turn lanes
