在互通式立体交叉设计中,设置双车道的分、合流处,应保持基本车道数的连续性,并维持车道数的平衡,必要时应增设辅助车道。当不能保证主线出入口间的应有距离或遇转弯车流的紧迫交织干扰主线车流时,应采用与主线相分隔的集散道将出入口串联起来。本文以互通立交设计实例对集散道和辅助车道进行详细介绍。
In the design of interchange three-dimensional crossover, if the two-lane points and confluence points are set, the continuity of the basic lane number should be maintained and the lane number balance should be maintained. If necessary, additional lane should be provided. When it is not possible to guarantee the proper distance between main entrances or exits or the tight interlacing of the traffic flow, the entrances and exits should be connected in series with the distribution mains separated from the main lines. In this paper, we give a detailed introduction to the collection and distribution lane and the auxiliary lane with the design examples of the interchange.
