城市道路交通组织精细化设计研究

Research on Fine Design of Urban Road Traffic Organization

随着社会的进步和经济的发展,人均汽车保有量不断增加,交通运行无序混乱、交通拥堵现象严重,交通事故发生率较高。从城市道路交通组织精细化设计角度出发,对兰州市平凉路段的交叉口渠化、信号控制等进行研究,并利用VISSIM软件仿真评价。研究表明,精细化设计在提高通行能力、保障安全、提高效率等方面具有积极作用。既保障了交通运行,更协调了沿线自然环境与社会环境之间的关系。

With the progress of society and the development of economy,the car ownership per capita is increasing,the traffic operation is in disorder,the traffic congestion phenomenon is serious and the traffic accident rate is high.From the perspective of fine design of urban road traffic organization,the channelization and signal control of the intersections in Pingliang Road of Lanzhou City are studied,and the VISSIM software is used to simulate and evaluate.The research shows that the fine design plays an active role in improving the traffic capacity,ensuring the safety and improving the efficiency,which not only ensures the traffic operation,but also coordinates the relationship between the natural and social environments along the line.
