大城市道路网结构型式评价的研究

本文以哈尔滨市道路交通模式为例．通过对国内外大城市道路网结构型式及其对应条件的分析，探讨了大城市道路网合理结构型式的基本概念，据此定义了城市道路网合理结构型式的评价指标，并应用模糊评价方法建立了综合评价指标体系。最后得出适合哈尔滨市具体条件的由分区环形道路、区间联系道路、外围环路组成的分区式道路网结构型式．由此提示在大城市道路网的规划与建设中应重视对道路网合理结构型式的论证。

Study on Evaluation of Structural Types of Urban Road Network

The paper approaches the basic concept of the reasonable structural type of urban roadnetwork by analyzing the urban road network structural types and corresponding conditions abroad and at home,taking the road traffic models of HaErBing City as an example. Thus it defines the evaluation targets of the reasonable stuctural types of the urban road network and establishes comprehensive eva1uatlon target system by applying the confused evalustion. At last,it obtained the road network strctural type in districts composed of the ring roads in distrlcts, interzone linking roads and peripheral ring roads,which is suitable to the actual conditions of haErBing City. Therefore, it shows that the demonstration of the reasonable structural types of roadnetwork shall be laid attention to in the planning and construction of urban road network.
