A Pilot Study on Interactions between Drivers and Pedestrian Features at Signalized Intersections—Using the SHRP2 Naturalistic Driving Study Data

Abstract

This paper aims to assess driver behaviors at signalized intersections with four identified pedestrian features (“Stop Here on Red,” “No Turn on Red,” “Turning Vehicles Yield to Pedestrians,” and “Right on Red Arrow after Stop”) via a pilot study by using an innovative safety data: Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) data. The major findings from the pilot study include: (1) “No Turn on Red” has the highest rate of compliance (70%), followed by “Right on Red Arrow after Stop” (67%), “Turning Vehicles Yield to Pedestrians” (67%), and “Stop Here on Red” (55%); (2) compared to control group (without pedestrian features), three features (“Stop Here on Red,” “No Turn on Red,” and “Right on Red Arrow after Stop”) increased the likelihood of compliant behaviors; and (3) mid-aged drivers (25-59) showed the highest percentage of compliance at feature sits (83%), followed by older drivers (60+, 69%) and young drivers (16-24, 61%).
