兰州市畅交通的思考与策略

随着城市的不断发展,机动车保有量极速增长,兰州城市交通拥堵在时间和空间范围上不断扩张,高峰期主要道路都处于高饱和运行状态,由交通拥堵而直接引发的环境、能耗、安全等诸多问题,也对城市经济的持续、快速、健康发展构成了一定的威胁。现通过对现状交通路网的分析与研判,提出按照“内联外拓、快捷优化、系统整合、整体提升”的总体思路、“纵横并重、先纵后横、保通兼畅、交通成网”的总体原则,疏通城区道路网和联通对外瓶颈公路网,加快构建“人便于行、车畅其流、便捷高效”的兰州市道路网,实现城市内外路网合理对接、高效衔接,全面提升道路交通对大兰州都市经济圈、兰白经济区经济社会发展的支撑和引领能力。其研究思路可供同类城市的交通规划提供一定的参考。

Thinking and Strategy for Smooth Traffic in Lanzhou

With the continuous development of the city and the rapid growth of motor vehicle ownership, the urban traffic congestion in Lanzhou is expanding in time and space, and the main roads are in a state of high saturation during peak hours. The problems of environment, energy consumption, safety and the others directly caused by traffic congestion also pose a certain threat to the sustainable, rapid and healthy development of urban economy. By analyzing and judging the current traffic network, according to the overall thinking of "internal join and external expansion, fast optimization, system integration and overall improvement" and the overall principle of "equal emphasis on vertical and horizontal, first longitudinal and then horizontal, smooth traffic, traffic into the network", the urban road network is smoothened and the external bottleneck road network is connected, and the construction of the road network of Lanzhou which is "convenient for people to travel, smooth for the flow of cars, convenient and efficient" speeds up. The reasonable connection and efficient connection of road networks inside and outside the city are realized, and the supporting and leading ability of road traffic to the economic and social development of Lanzhou Metropolitan Economic Circle and Lanbai Economic Zone. The research thinking can provide the reference for the traffic planning of similar cities.
