摘要
隨著我國城市化進程的不斷加快，城市建設與城市交通的矛盾日漸突出，同時，現(xiàn)階段交通問題日益突出。城市交通問題已經(jīng)影響了城市功能的充分發(fā)揮，造成交通運輸成本和時間成本的增高。在改變這一問題的努力中，平面信號交叉口評價體系研究工作起著非常重要的作用。平面信號交叉口評價體系研究能為城市交通管理部門提供一個用來評價作為城市路網(wǎng)主要結(jié)點的信號交叉口的科學工具，以達到充分挖掘城市潛力，提高交叉口服務水平的目的。本文借鑒了國內(nèi)外關(guān)于城市信號交叉口評價的方法，分析了對于平面信號交叉口的影響因素，運用層次分析法對鎮(zhèn)江市學府路江蘇大學中門信號交叉口做出了系統(tǒng)的評價。評價內(nèi)容綜合了平面交叉口的服務水平、設計指標、管理因素和環(huán)境影響四個大方面;通行能力、延誤、飽和度、沖突點、渠化程度、事故數(shù)量、交叉口類型、標志標線、信號燈配時、自然環(huán)境和社會環(huán)境十一個小方面建立了一個相對簡化的評價方法，突出對動態(tài)交通的評價和實際的應用。

Abstract

Along with the process of the urbanization that speeding up ceaselessly, the contradiction of urban construction and urban communications is becoming more and more critical.At the same time, the traffic problems have becoming increasingly prominent. Urban communications problems have affected the full role of the urban function, resulting in the increased transportation costs and time costs. To change this problem ，appraisal system of urban signalized intersection is playing a very important role.It can provide a pattern to eva luate the urban road network of signalized intersection .It can also be the important reference for export or scientific tools for traffic management departments of city. In order to achieve full potential of the city ,it should improve the intersection service level. This paper uses the methods that both home and abroad about the urban signalized intersection eva luation, analyzes the influence factors of the signalized intersection and using analytic hierarchy process to make a systematic eva luation for Jiangsu University signal intersection of Zhenjiang City Xuefu Road. The assessment content which is comprehensively include four big aspects of intersection service level, design element, management and environmental factors.There has traffic capacity, delay, saturation, conflict point, degree of channelization, the number of accidents, intersection types, signs and markings, signal timing, natural environment and social environment eleven small aspects.This paper established an eva luation method that is relatively a little bit simple than before.And this method of eva luation applied the dynamic traffic and actual use prominently.
