A Probabilistic Model to Predict Intermittent Sight Distance Obstruction at Unsignalized Intersections on High-Speed Rural Divided Highways

Chennan Xue and Dan Xu

Minor-road left-turn vehicles’ views are likely to be blocked by major-road right-turn vehicles on the conventional right-turn lane at unsignalized intersections.

NEW! NCHRP Research Report 875: Guidance for Evaluating the Safety Impacts of Intersection Sight Distance is a resource for practitioners involved in the planning, design, operations, and traffic safety management of stop-controlled intersections. It provides information on how to estimate the effect of intersection sight distance (ISD) on crash frequency at intersections and describes data collection methods and analysis steps for making safety informed decisions about ISD.
