Multi-Method Investigation of Pedestrian Safety Impacts of Right-Turn Lanes
Dedicated right-turn lanes reduce traffic delays on urban roads (Potts et al., 2007), and typically results in a reduction in motor vehicle crashes for both urban and rural roadways, although the magnitude of the crash reduction is greater for rural compared to urban roadways, and unsignalized intersections compared to signalized intersections (Harwood et al., 2003). However, the safety impact of dedicated right-turn lanes on pedestrian safety is relatively understudied. The objective of the proposed study is to more clearly determine the consequences to pedestrian safety posed by the features of conventional right-turn lanes. The safety consequences to pedestrians will be assessed looking at available research, crash data, and observable human behavior in right-turn lanes both on urban roads in Minnesota and in a safe, simulated environment. This study will add value by fostering livable communities by determining the trade-off between efficiency in traffic flow with right-turn lanes versus the potential risk to pedestrian safety and lives.
