城市路段混行交通特性研究.doc

（ 二 〇 一 二 年 六 月 摘要 目前，我国城市交通中的机动车和非机动车混合行驶的道路大量存在由于市民的现代交通意识淡薄，交通违纪现象严重，车流的运行中，机非干扰现象比较严重。另外，有些公交站点的设置不合理时，公交车的停靠站，也会加剧交通的拥堵，给小汽车驾驶员带来不便。以上这些问题给交通设施带来了很大的压力，从而出现了交通拥堵，交通事故频发和交通环境的污染等问题。这些问题制约这经济的发展速度。因此，研究城市道路交通特性对缓解交通拥堵问题就有重要意义。 本文首先总结了国内外研究成果Now, mixed traffic road shared by automobiles and non-automobiles largely scatters in our country. Because the citizen don’t attach importance to the traffic rules and the phenomenon of breaking the traffic rules is very serious, mutual action between those two kinds of vehicles grows with the increasing quantity of personal vehicle and bicycle. In addition, when some bus stops are settled unreasonably, the stopping of the bus also sharpen traffic congestion and the drivers of the cars don’t feels convenient. These problems bring very big pressure for the traffic establishment，so there are more and more traffic congestion, traffic accident and traffic pollution. They restrict economic development. Then there will be important significance researching traffic characteristic of urban road to alleviate the problem of traffic congestion. At first, it summarized relevant research in our country and other countries. Some new functions model were put forward, which show the connection between non-automobiles influencing automobiles and no non-automobiles influencing automobiles, including traffic volume, speed, density. Besides, some new functions were put forward, which show the connection between bus influencing automobiles and no bus influencing automobiles, including traffic volume, speed and density. And it did further research on traffic congestion， that is, it put forward evaluation index of traffic congestion and established methods of judging traffic congestion. Keywords: mixed traffic flow; bus influence; traffic characteristic; function model; traffic congestion  目录 第一章 绪论 1 1.1立题的背景和意义 1 1.2国内外研究状况 2 1.2.1国外研究进展 2 1.2.2国内研究进展 3 1.3论文的结构安排 4 1.4本章
