| 摘要： | This report provides a preliminary analysis of signalized intersection, straight crossing path (SI/SCP) crashes to support development of crash avoidance system (CAS) functional concepts as part of the Intelligent Vehicle Highway System (IVHS). An SI/SCP crash is defined as a crash at a signalized intersection in which two vehicles, one with and one without right-of-way, collide in straight crossing paths. A detailed analysis of 50 such crashes shows that 41% of these crashes are caused by drivers who were unaware of the signal presence and its status, and that 16% were caused by drivers who attempted to beat the amber phase. The CAS concepts discussed in this report are driver alerts, driver warnings, partially automatic control systems, fully automatic control systems, and a hybrid system that incorporates the previous four concepts and transitions among them. The report also provides kinematic models to determine the time and distance available for crash avoidance under various vehicle operating conditions. The report concludes with a number of research needs to better understand SI/SCP crashes and guide CAS development. |
