• Abstract:
  Leading Pedestrian Intervals (LPIs) and Curb Extensions (CEs) are operational and geometric countermeasures that are designed to reduce pedestrian injuries and fatalities. While Oregon DOT implements both of these treatments, there is limited guidance on how to implement these options (separately or in combination with other treatments). The present research study aimed to fill gaps in existing knowledge to improve pedestrian safety at signalized intersections by developing enhanced guidance on when and where to implement LPIs either solely or in conjunction with complementary treatments such as CEs. The field work data includes field observed volumes and conflicts between pedestrians and motor vehicles. The driving simulator data includes turning speed, approach speed, total fixation duration across four areas of interest (traffic signal, pedestrian signal, No Turn on Red (NTOR) sign, pedestrian), and survey data (pre-survey and post-survey). ; After pasting the abstract, then hit enter twice.
