Abstract

Potential safety impact of a hypothetical intelligent cruise control system (ICCS) is evaluated in terms of changes in traffic accidents and some traffic operation characteristics affecting safety. The analysis of changes in traffic accidents is accomplished by in-depth examinations of police accident reports for four major counties in California. The evaluation of changes in traffic operation characteristics affecting safety is accomplished by vehicle simulation. The accident analysis reveals that the use of the hypothetical ICCS could potentially reduce traffic accidents by up to 7.5%. Preliminary vehicle simulation results based on a 10-vehicle convoy indicate that the use of the hypothetical ICCS could reduce frequencies of hard acceleration and deceleration, enhance speed harmonization among vehicles, and reduce incidence of "less-safe" headway.

摘要

通过交通事故的变化以及一些影响安全的交通运行特征，对一种假设的智能巡航控制系统（ICCS）的潜在安全影响进行了评估。通过深入研究加利福尼亚州四个主要县的警方事故报告来完成交通事故变化的分析。通过车辆模拟来完成对影响安全的交通运行特征变化的评估。事故分析表明，使用这种假设的ICCS有可能将交通事故减少多达7.5%。基于10辆车组成的车队的初步车辆模拟结果表明，使用这种假设的ICCS可以降低急加速和急减速的频率，提高车辆之间的速度协调性，并减少“不太安全”的车间距发生率。
