Project summary:

Dedicated right-turn lanes reduce traffic delays on urban roads (Potts et al., 2007), and typically result in a reduction in motor vehicle crashes for both urban and rural roadways (Harwood et al., 2003). However, the impact of dedicated right-turn lanes on pedestrian safety is relatively understudied. The objective of this study is to study the relationship between right turn lanes, pedestrian safety and pedestrian crash risk. The safety consequences to pedestrians will be assessed by 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 developing recommended guidelines for the installation of right-turn lanes that incorporates/considers their impacts on pedestrian safety.
