Crash Risk Factors at Rural Two-Way Stop-Controlled Intersections
Publication: International Conference on Transportation and Development 2020
ABSTRACT
Rural intersection safety continues to be a crucial issue throughout the United States. More than 20% of all traffic fatalities in the United States occur at intersections, and over 80% of intersection-related fatalities in rural areas occur at unsignalized intersections. This paper investigates the significant factors affecting crash severity at stop-controlled intersections on rural two-lane highways in Louisiana. Roadway characteristics, traffic characteristics, and crash characteristics were collected from 5,136 stop-controlled intersections including both three-leg (3T) and four-leg (4T) of all 64 Parishes (counties) statewide, for the period of 2013 to 2017. Zero-inflated Poisson (ZIP) models were developed to model the number of intersection crashes for different severity levels. In addition to traffic volume, horizontal curve radii, speed limits of major roads, and intersection skewness also have significant impact on crash occurrences.
