• Abstract:
  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 the 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. Moreover, about 75% of UI/SCP crashes were caused by drivers who were unaware of the presence of either the stop sign or crossing traffic. The Crash Avoidance System (CAS) concepts discussed in this report include driver alerts, driver warnings, partially automated control systems, fully automated control systems, and a hybrid system that incorporates these concepts and transitions among them. This report concludes with a number of research needs to better understand UI/SCP crashes and guide CAS development.
