摘　　要：利用咸阳市卫星影像和城区道路规划资料,在对城区道路数字化的基础上,通过抽样调查道路交通状态,运用道路通达度分析模型,从城区道路系统布局和道路通行效率两方面入手,对城区道路网络体系的通达度指标及其空间分布格局进行分析,探究其交通网络建设中的结构性问题,旨在为改善咸阳市城区道路通行效率提供依据。结果显示咸阳市城区道路系统存在道路密度分布不均,渭河分割效应明显,缺乏过境通道等问题。在以后的道路建设中应加大交通投入,加强支路建设,同时应尽快修建咸阳市环城道路。Based on the digital street network derived from high-resolution satellite image, traffic map of XianyangCity and transportation investigation, starting from the analysis of urban road layout and road traffic efficiency, u- sing GIS technique and road accessibility analysis model, this paper evaluates space accessibility of Xianyang streetnetwork and analyzes its spatial distribution pattern. The aim is to analyze the structural problems in the construc- tion of traffic network and provide scientific basis for improving road traffic efficiency of Xianyang City. The results show that because of the Weihe River division, roads unevenly distributed throughout the Xianyang City and lackedtransit roads. To improve the efficiency of road in the future road construction, Xianyang government should in- crease investment, reinforce urban branch road, and build the ring road as early as possible.
