Advanced Yield Markings and Drivers' Performance in Response to Multiple-Threat Scenarios at Mid-Block Crosswalks


This study compares on a simulator drivers' performance (eye fixations and yielding behaviors) at marked, midblock crosswalks in multi-threat scenarios when the crosswalks have advance yield markings and pedestrian crosswalk prompt signs with their performance in such scenarios when the crosswalks have standard markings. Uncontrolled mid-block crosswalks at multilane streets are associated with a type of pedestrian-vehicle conflict defined as a multiple-threat crash scenario. A pedestrian is struck by a vehicle (first threat) traveling in the same direction as a vehicle (second threat) that is yielding or stopped for a pedestrian in the crosswalk. Vehicles yielding or stopped too close to the crosswalks often block the driver's visibility in the approaching vehicle (traveling in the adjacent lane) of the pedestrian in the crosswalk.
