基于兰州城市交通拥堵现状的导向标识系统设计研究

The study of traffic guiding sign system design based on the current traffic situation of Lanzhou

近年来,兰州市交通越来越堵,严重制约了城市的可持续发展,引发了众多学科学者广泛的研究与讨论。从目前地形结构特点来看,兰州是典型的河谷阶地城市,城区东西较长,南北狭窄且受到皋兰山、白塔山的阻挡,城区道路无法向外扩展。因此,必须通过合理、有效的疏导交通流来缓解交通拥堵。清晰、完整、科学、规范的交通导向标识系统是兰州城市交通疏导的灵魂。本文首先深入分析了兰州市目前交通拥堵现状和成因,研究了兰州市的城市交通导向标识系统建设的现状及其在兰州市交通拥堵疏导过程中所起的重要作用。在此基础上,制定了兰州市交通导向标识系统的设计原则,从而以更高效的疏导交通流来缓解兰州城市的交通拥堵。

In recent years,the traffic jam becomes a more and more serious problem to impede development of Lanzhou,and has been attracted extensive attentions from many specialists.As far as land structure is concerned,the city of Lanzhou is a typical river terraces,it is very long along the East-West direction,but narrow along the North-South direction,which makes the urban road extending difficult.Thus,it is necessary to evacuate reasonably and effectively the traffic flows,and the development of the clear,complete,scientific and normative guiding sign system of public traffic is a critical factor for the evacuation of urban traffic jam of Lanzhou.So in the paper,based on the analysis on the current situation of the urban traffic guiding sign system of Lanzhou,the design principle of traffic guiding sign system of Lanzhou is given,and it will be beneficial to the evacuation of urban traffic jam of Lanzhou.
