  • Abstract:
    Vehicle drivers are expected to yield to pedestrians when there are conflicts, however drivers may fail to see pedestrians and react to pedestrians when they are influenced by various factors such as the surrounding traffic, intersection geometric, vehicle condition or driver condition. This Implementation Assistance Program (IAP) project sponsored by the second Strategic Highway Research Program (SHRP 2) is to study how driver, vehicle, roadway and environmental factors affect the turning-drivers vision and yielding to pedestrians at intersections with the RID and NDS data. Research findings will be used to guide development and implementation of effective countermeasures for pedestrian safety at intersections. The Phase 1 project was a proof of concept using reduced SHRP2 safety data. In this phase, the research objective was to demonstrate the ability to conduct meaningful research in advancing our understanding of driver behavior using the new SHRP2 safety data. This report documents the results of the Phase 1 research performed by the Center for Advanced Transportation Education and Research (CATER) at the University of Nevada, Reno (UNR) and supported by the Nevada Department of Transportation (NDOT). With the full RID dataset and the NDS data at selected intersections, the influence of different factors on driver observation behavior was analyzed, and quantified as a factor influence index. Selected factors were prioritized based on the developed factor influence index matrix. The relationship between pedestrian-turning-vehicle crashes and driver behavior pattern, and the relationship between countermeasures and driver behavior were also studied with two cases for research method demonstration. Conclusions on the Phase 1 project and recommendations for future research were provided for countermeasure selection and development with the new SHRP 2 Safety Data. In this report, the Phase 2 research proposal is included with a schedule and budget. This report is organized as follows: Chapter 2 presents the literature review on the understanding of pedestrian crashes and recommended counter measures to avoid pedestrian-turning-vehicle crashes; Chapter 3 introduces the data used and data processing procedure; Chapter 4 documents the methodologies used in the Phase 1 study; Chapter 5 summarizes research results; Chapter 6 proposes the future research direction; and Chapter 7 is the proposal for the SHRP 2 IAP Phase 2 project.
