基于多级可拓方法的城市公交枢纽站布局评价

Evaluation of Urban Public Transit Hub Stations Based on Multi-level Extension Evaluation Method

将可拓工程方法与城市公交枢纽站评价因子相结合,建立了城市公交枢纽站多级可拓评价模型.该模型基于简单关联函数和相似系数法计算各评价指标的权重,能从待评样本寻求各评价指标的客观权重;对城市公交枢纽站布局进行一级和二级可拓评价,给出布局方案等级评定.实例结果表明,该参评因素可拓权重确定方法可有效避免主观因素的影响;城市公交枢纽站多级可拓评价可最大限度地对评价指标信息进行综合,从而客观、合理地反映了布局方案优劣.

Combining extension evaluation method with evaluation factors of urban public transit hub stations, a multilevel extension evaluation model is established to evaluate urban public transit hub stations. The model calculates the weight of evaluation index based on the simple correlation function and similar coefficient method, and can determine the index objective weight resulting from sample da ta themselves. Based on the primary and secondary extension evaluation method, the evaluation of ur ban public transit hub stations is determined. Then, ranking assess of the layout plan is given. Appli cation example results show that the extension weight method of evaluation factor can effectively avoid the subjective factor influence. The evaluation of urban public transit hub stations based on multilevel extension evaluation method can furthest generalize the information of evaluation indexes, and can re flect the plan is good or bad objectively and reasonably.
