摘　　要：目前对道路网方案比选的研究主要集中于道路网的交通功能比选上,本文引入交通效率的概念把道路网络的建设费用投入,满足城市交通需求的正效应以及环境污染、能源消耗的社会负效应联系起来,建立评价指标体系,研究基于交通效率的城市道路网络方案比选方法,综合体现城市交通系统的交通功能目标、环境保护目标和资源利用目标,为规划建设高效率的、支持可持续发展的城市道路网络提供理论依据和方法。At the present time, the research about selecting urban road network is focused on the trans port function. In this paper, transport efficiency is taken as the bridge to connect the building expenditure of road network, plus efficacy satisfying transport demands and negative efficacy of environment pollution and re source consuming. Then, the system of indexes to assess and select road network is built and the method is studied. This system can realize the objective of transport function, environment protection, and resource us age, or the three objectives of urban transport systems. It provides theory and method for planning and build ing urban road network with high efficiency and supporting sustainable development.
