基于区间和多目标的城市交通方式评价

Evaluation of Urban Traffic Mode Based on Fuzzy Property and Multi-objective

由于交通系统的复杂性,很多交通方式属性值只能用区间等模糊形式来表示。针对区间交通方式属性,分析可持续发展条件下的城市交通方式评价体系,通过对向量规范法进行改进实现交通方式属性间的可公度化,进而建立基于交通方式点到正负理想点"距离"的多目标评价模型。最后通过实例进行分析和验证,表明评价模型在区间交通方式属性评价中的有效性。

Due to the complexity of the urban traffic systems, lots of traffic properties can only be described from the fuzzy standpoint. Based on this idea, the paper addresses the evaluation of the structure of urban traffic modes. The properties of commensurability can be achieved by improving a tradition model. Furthermore, a multi-objective evaluation model with the best and worst points is formulated. A numerical example is presented to illustrate the effectiveness and efficiency of the proposed fuzzy property-based evaluation model in the valuing the modal structure of the urban traffic system.
