摘要

随着当今世界经济的高速发展，城市现代化进程日新月异，城市道路的意义愈显的举足轻重。城市道路是一个城市的骨架，同时又是一个城市的大动脉。理想的道路在满足交通运输和出行需要的同时，还会带给人们美的感受。在城市化水平不断提高的今天，城市道路在经济发展中的作用日益增大，人们对城市道路功能的期望值也越来越高，因此城市道路综合设计的作用就显得举足轻重。

而其中道路交叉口又是整个城市交通系统中的重要节点，是车辆、行人汇集、转向和疏散的必经之地，为交通的咽喉。与普通道路相比，交叉口路况更复杂，人流量车流量更大，同时交叉口也是交通事故的多发地段。因此，正确设计道路交叉口，合理组织、管理交叉口交通，是提高道路通行能力和保障交通安全的重要方面。为了实现城市道路交通的畅、通，提高城市道路的通行能力和通行效率，围绕交叉口设计以及交叉口交通管理与控制做了很多研究。

本论文主要通过实际实地调查，获取邯郸市浴新南大街当前的管理现状、道路几何条件、交通流量、地点车速、行车延误等基础资料，从交通管理、交通组织方面做定性现状分析，从饱和度、延误、排队长度、通行能力等方面做定量现状分析，探寻此道路沿线及交叉口存在的问题。利用信号城市道路设计理论、交叉口渠化理论等进行探讨和设计，提出包括道路拓宽、车道变更、交叉口渠化等方面综合性的改善措施和相应的改善方案，减少交通拥堵、交叉口冲突和延误，增大通行能力，提高整条道路通行效率。

Abstract

With the rapid development of the world economy, city modernization change rapidly, play a decisive role in city road sense more. City road is a skeleton of city, also is the main artery of a city. The ideal way to meet the transportation and travel needs at the same time, will also bring people aesthetic feeling. In the city the continuous improvement of the level of city road today, role in the development of economy increasing, expectations for city road function value is more and more high, so the city road design appears to play a decisive role.

And the road intersection is an important node in the city traffic system, vehicle, pedestrian collection, steering and evacuation of the necessary land, into the throat of the traffic. Compared with the general road, intersection traffic more complex, the flow of people flow more, at the same time, intersection and traffic accident-prone locations. Therefore, the correct design of the road intersection, traffic organizing, management of intersection, is to improve the traffic capacity and ensure traffic safety important aspect. In order to realize the city road traffic problems, through the city, improve the road capacity and traffic efficiency, around the intersection design and traffic management and control has done a lot of research.

This paper mainly through the actual field survey, obtain new South Street, Handan city bath management present situation, the geometric conditions, traffic flow, speed, location of basic data such as traffic delay, traffic management, traffic organization from the qualitative analysis of the status quo, from saturation, delay, queue length, capacity and other quantitative analysis of present situation, to explore this along the road and intersection problems. Using signal city road design theory, intersection channelization theory and design, proposed including road widening, lane change, intersections and other aspects of the comprehensive improvement measures and the corresponding improvement scheme, reducing traffic congestion, the intersection conflict and delay, increase capacity, improve the whole efficiency of road.
