摘要

随着经济的不断发展，城市的扩大，对道路通行能力有了更高的要求。目前贵阳市的交通状况不佳，大部分道路出现严重的交通拥挤现象，使得道路通行能力明显降低。而对贵阳市经济繁荣中心的交通通行能力要求更高，本篇论文选择了贵阳市中华中路路段与服务大楼交叉路口进行研究。

由于中华中路含有路段龙港百盛至大十字和龙港百盛至喷水池，由于喷水池是贵阳的市中心，周围交叉路段，路口较多，大型商场比较集中，交通设施较为成熟，因此研究主要是针对交通高峰时期进行研究并发掘内在原因，并采取有效措施缓解失衡的供求关系，可以通过建设环线道路与推进路外停车场规划建设缓解日趋紧张的交通压力。

本论文的结构：首先是根据贵阳市交警支队统计的18个路段的数据，选取其中一个路段和一个交叉路口进行分析研究，通过机器计数法得到2009年2月16日—2月22日的数据，通过研究一天各种车型的流量分析和一周各种车型的流量分析，并对交叉路口的单一方向和不同方向的流量分析，对高峰期的时间段与流量进行研究，得到各个路段交通的不均衡性，并对高峰期进行调查研究，得出改善交通不均衡性的解决方案。

Abstract

With the continuous development of economy, cities have been expanded substantially, which caused the urgent demand of high-standard road capacity. However, the transportation in Guiyang is still underachieved currently. Traffic congestion exists in most of the roads, so that road capacity is significantly reduced. What’s more, the highly prosperous center in Guiyang calls for greater efficiency of road capacity.This paper is focusing on the crossroads near Zhonghua Zhong road and the Service Building.

Zhonghua Zhong road includes the path between Longgang Parkson and large cross (Da Shi Zi), and the path from Longgang Parson to the fountain. Because the fountain is the very centre of Guiyang (the capital city of Guizhou province) with many crossroads and intersections, gathering numerous megastores around it, the traffic facilities are relatively mature. This research deals with the basic reasons for traffic congestion in rush hour, and gives some effective measures to solve the unbalance of supply and demand. For example, advocating and building annular roads, off-street parking lots or other useful facilities can alleviate the increasingly traffic pressure.

The structure of the paper: firstly, according to the statistics of 18 paths’ traffic flow by the detachment of Guiyang’s traffic police, we have chosen one path and one crossroads as our research object. Secondly, based on the statistics from February 16th, 2009 to February 22ed, we have made a calculation of each vehicle’s flow during one day and one week respectively through machinery counting process. Besides, we have analyzed the vehicle flow of one specific direction and different directions and the vehicle flow in rush hour. Finally, we note the transportation unbalance of each road. The last part concerns about the solutions to such transportation unbalance.
