备注

为解决高速公路互通式立交出口交通事故多发的问题,基于现行判定理论,利用所收集到刹车痕迹集中点的位置分布,提出定量计算刹车痕迹集中点处痕迹数量的方法.结合互通式立交出口处路线几何指标及其附近预告标志牌信息量,分析高速公路立交出口刹车痕迹集中的原因,提出导致刹车痕迹集中现象主客观原因的界线标准. 结果表明,该判定方法找出了客观影响因素占主导的互通式立交问题出口,确定了其优先改善次序. 通过持续循环利用本方法对该问题出口节点集中位置的检查和改善,提高了车辆的运行顺畅,降低了不合理紧急制动发生的概率.

Rational designs of highway exits are important to the safety of public transportation and highly emphasized in highway engineering. Current methods for evaluating highway exits, however, cannot effectively find problems with highway interchanges. In this paper, by analyzing the distribution of centralized brake marks, a method to quantitatively calculate the number of marks at the focus points is proposed. This method, combined with the geometric index of interchanges at the exit route and the trailer signs information, can be used to investigate the systemic causes of the concentration of the braking marks. In addition, the subjective and objective factors causing the concentration of the braking marks can be differentiated. The results show that the new method can be used to find the objective factors in the safety concerns of interchanges and determine the priority for improvement. This method can be used to improve the smooth operation of the vehicles, reduce the probability of occurrence of unreasonable emergency braking and, finally, increase the safety of interchanges.
