摘要
高等级公路沿线大量的道口增加了车辆的冲突点,造成车速下降,大大降低了公路的通行能力和服务水平,增加了事故隐患。因此,有必要从行车视距的角度,定量分析公路沿线搭接道口的最小间距,给出不同行车速度下的交叉道口间距,为公路管理部门对搭接道口的审批提供技术依据。
Large number of joint intersections along expressway increase conflicts for vehicles, which lead to the decreasing of speed and traffic capacity and service level with increasing of accidents. Therefore, it is necessary to analyze quantitatively the smallest distance between intersections from the point of running inspection distance, and present travelling visual distance so as to provide technique foundation for examining and approving of highway administering departments.
