摘要
枢纽互通立交是进行高速公路之间交通转换的重要节点,对于车道数不同、交通量相差较大的两条高速公路之间的互通立交,其匝道形式、线形布局和交通组织也较为复杂。结合工程实例,探讨非对称型枢纽立交变速车道的设计要点,尤其是当匝道交通量较大且主线发生车道数变化时,基于车道数平衡的原则,如何进行立交加减速车道的设计要点。
Hub interchange is the important node of the traffic conversion between highways. The ramp form, alignment layout and traffic organization are more complicated, when lane number and traffic volume are different. Combining with engineering examples, in this paper, the main design points for the speed change lane of the asymmetric hub inter-change have been discussed, being based on the principle of balance of the number of lanes, especially when the traffic volume of the ramp is large and the number of the highway mainline changes.
