摘　　要：城市道路的出入口是沿线单位在路段上的开口,车辆在进出时会进行减速、加速、换道和转向等行为,这些行为可能会影响路段通行,造成交通拥堵等问题。由于物流园内其车辆的特殊性(大型车辆为主),其出入口的通行问题需要特别重视。文章旨在通过研究物流园出入口的通行能力,分析是否需要对出入口进行优化。为此,我们基于交通流动力学原理建立了模型,并对模型进行了优化,以计算出实际通行能力。接着,应用该模型对兰州国际港务区保税物流园进行了交通组织优化设计的实例研究。The entrance to and exit from urban roads is the opening of units along the road section.Traffic slows down,accelerates,changes lanes and swerves in and out of urban roads.These behaviors may affect traffic on road sections,causing problems such as traffic congestion.Due to the particularity of vehicles in the logistics park(mainly large vehicles),the problem of access to and exit from the park needs more attention than others.In this paper,the access capacity of the logistics park is studied to see if the target access needs to be optimized.The actual traffic capacity is caculated,based on the traffic flow dynamics principle to establish and optimize the model.The traffic organization optimization design of bonded logistics park in Lanzhou International Port Area is carried out by using the model.
