高速公路隧道交通环境评价指标体系

根据高速公路隧道交通流变化规律及交通运行环境特性，提出了高速公路隧道交通环境评价指标选取的原则，从最佳服务水平、最小运营费用的角度出发，按照各种评价指标对高速公路隧道交通运行环境影响的显著程度，采用德尔菲法和主成分分析法对指标进行对比分析，从交通影响因素指标、环境影响因素指标、动态影响因素指标3个方面，建立了高速公路隧道交通运行环境评价指标体系，并探讨了各评价的功能，旨在为高速公路隧道交通运行环境评价的实施提供理论基础。最后，对京珠高速公路粤境韶关段隧道的交通环境评价指标进行实证分析。结果表明，该评价指标体系简便实用，符合实际。

Evaluation Indices for Traffic Environment of Expressway Tunnel

According to the changing rule of traffic flow and the characteristics of traffic running environment in expressway tunnel,this paper puts forward the selecting principle for evaluation indices of traffic environment in expressway tunnel.From the views of optimal service level and the minimum running cost,the evaluation indices are analyzed with Delphi and the Main-Element Analytical Method.According to the affecting degree of various indices on the traffic running environment,an evaluation indices system for traffic running environment is established,which is composed of three aspects: traffic effect factor indices,environment effect factor indices and dynamic effect factor indices.The function of each index is also discussed in order to offer theoretical base for the evaluation of traffic running environment of expressway tunnel.This evaluation indices system is applied in evaluating the Beijing-Zhuhai expressway tunnel in China.The results indicate that the evaluation indices system is easy to be used and is accord with the practice condition.1 fig,7 refs.
