Examination of Unsignalized Intersection, Straight Crossing Path Crashes andPotential IVHS Countermeasures

摘要

This report provides a preliminary analysis of unsignalized intersection,straight crossing path (UI/SCP) crashes and applicable countermeasure concepts for the Intelligent Vehicle Highway System (IVHS) program. A UI/SCP crash occurs when two vehicles, one with the right-of-way and one without, collide at right angles while both are attempting to pass straight through an intersection controlled by stop signs. A detailed analysis of 100 such crashes showed that drivers ran the stop sign in about 42% of these crashes and that the remaining crashes involved drivers who stopped and then proceeded against cross traffic.
