摘　　要：在我国有关的道路设计规范中,并没有对主线收费站和非信号控制交叉之间的净距进行规定,为了进一步研究这两者之间的净距,在分析设置交通标志、车辆变道和平面交叉口的安全视距等影响因素的基础上,结合与主线收费站连接的不同形式的交叉口,建立了主线收费站与非信号控制交叉净距的计算模型,并根据我国交通流的运行状况,合理地确定了模型中参数的取值,最后得出不同交叉口类型、不同运行速度下主线收费站与非信号控制交叉净距的建议值,研究成果对我国设置主线收费站与非信号控制交叉口之间的距离有一定的参考作用。There is no stipulations to the net distance between the main line toll stations and non-signal control crossings in the current highway design specifications in China. In order to study the net distance between these two, through analysis of influencing factors such as traffic markings, vehicles lane changing and safe sight distance at plane intersections, combining different type crossings with main line toll stations, a model of calculating the net distance between the main line toll station and non-signal control intersection is established, and according to the running status of traffic flow in China, the values for parameters in the model are determined properly, and the net distance values are drawn finally with different intersection type and different running speed. The results have some reference value for setting the distance between main line toll station and non-signal controlled crossings in China.
