Application of Multi-Level Extensible Method for City Highway Environment Status Evaluation
【摘要】 根据城市高速公路环境影响因素的特点和文献中的评价指标体系以及相应的指标特征值,比较全面、系统地构建城市高速公路环境现状评价指标体系.建立以可拓法为核心的城市高速公路环境现状的多级可拓评价模型.并以西安市某高速线路为实例,确定该线路及其运营子系统的等级度.理论分析和实例计算表明:该方法在城市高速公路环境现状评价中有较好的适用性.
【Abstract】 According to city highway environmental impact factors and the characteristics,the evaluation index system and the corresponding index characteristic value,a more comprehensive city highway environmental status evaluation index system is constructed based on extension method as the core of urban expressway environment of the present situation of the multilevel extension evaluation model.Taking a high-speed lines in xi’an city as an example,the level of the lines and their subsystems is determined.The theory analysis and numerical examples indicate the feasibility of the method in urban expressway in the evaluation of the status quo of environment.
