交通拥堵、道路通行能力低已经成为制约我国城市物流发展的重要因素,以城市配送为例,车辆的实际运行时间大大低于道路上的停滞时间,造成了物流资源利用效率大大降低。从目前的常规理念来看,传统的设计思想是车辆运行完全依赖于一般道路,造成车辆通行资源的单一化,道路的设计压力和约束也越来越大,出现了车辆通行不畅的难题。为了改变这一现状,需要更新道路系统的设计理念,引入新的工程技术,扩展交通设计手段,建立交通体系新的构建策略,助 Traffic congestion and low traffic capacity have become an important factor restricting the development of urban logistics in our country. Taking urban distribution as an example, the actual running time of vehicles is much lower than the dead time on the roads, resulting in the greatly reduced utilization efficiency of logistics resources. From the current general idea, the traditional design idea is that the vehicle operation is completely dependent on the general road, resulting in the simplification of vehicle access resources. The pressure and restraints on the design of the road are also getting bigger and bigger, resulting in the problem of poor traffic access. In order to change this situation, it is necessary to update the design concept of the road system, introduce new engineering technologies, expand the means of traffic design, and establish a new construction strategy for the transport system.
