Driving Simulator Evaluation of Red Arrows and Flashing Yellow Arrows in Right-Turn Applications

The flashing yellow arrow (FYA) for right-turn applications and a dynamic no-turn-on-red sign were evaluated using a computer-based static survey evaluation to determine whether drivers grasp the message of the devices. The study evaluated the results from 200 respondents based on the existing passive green and red phase conditions, the proposed right FYA, and a dynamic no-turn-on-red sign. Results indicate that drivers have a strong comprehension of the FYA and dynamic no-turn-on-red messages. There was a significant statistical difference in responses in terms of the increase in the response designating the action of yielding as approaching the intersection from the existing condition to the FYA. As part of a field-based evaluation, vehicle-pedestrian interactions were documented on sites with and without an FYA indication on the right turn as well as on a site with an FYA indication on the right turn. Documentation of the interactions was achieved using a frame-by-frame analysis of video recordings from the sites. A model explaining the deviation of a driver from an expected right-turn behavior as a result of the presence of a pedestrian was created. The model takes into consideration the position of a pedestrian within the crosswalk as well as the presence of an FYA indication on the right turn. The feasibility of creating the model demonstrates the possibility of assessing the quality of a future driving simulator experiment on the application of FYA for right turns.
