一、引言物流园区出入口是园区内外交通连接的瓶颈,其合理规划设计,对提高道路通行能力,提升车辆行驶安全度有着十分重要的作用,是物流园区交通规划不可或缺的部分。物流园区出入口的规划设计主要是园区机动车出入口的设置问题,如果物流园区机动车出入口的设置缺乏科学性,使得出入口路段成为该区域交通的瓶颈,势必会造成通行能力的降低,通行时间的不必要浪费,进而影响交通安全,制 I. INTRODUCTION The entrances and exits of the logistics park are the bottlenecks of traffic connections both inside and outside the park. The rational planning and design of logistics park entrances and exits plays an important role in improving the capacity of roads and improving the driving safety of vehicles. It is an indispensable part of traffic planning in logistics parks. The planning and design of the entrance and exit of the logistics park is mainly the setting of the entrance and exit of the park motor vehicles. If the entrance and exit of the motor vehicle park in the logistics park lacks scientificity, the entrance and exit sections become the bottleneck of the traffic in the area, which will inevitably reduce the traffic capacity and the passage time Necessary waste, thereby affecting traffic safety, system
