摘要
构建了南通市区"102030"交通畅通工程计划的道路网络,以GIS空间网络分析为基础,分别以3种车速对"102030"交通畅通工程目标进行了模拟.研究发现:在不发生拥堵时,该工程的通行时间目标基本能够实现;拟建汽车东站比长途汽车站具有更好的内外通达能力,从出城便捷度角度考虑,汽车东站的选择是合适的;南通市区城市组团和对外交通呈现明显的近似等腰三角形布局特点,这一特点解释了该市区对外交通通达时间空间分布结构.
In this paper,the road network that after completion of ＂102030＂ smooth traffic project by the end 2013 in Nantong is constructed,based on GIS spatial network analysis,the objects of the ＂102030＂ smooth traffic project are being validated by simulating 3 kinds of velocities.The results indicate that： objects of the projections can nearly be achieved when there is no traffic congestion.The area selection of eastern bus station is reasonable in the view of convenience because it enjoys better accessibility than the old bus station.Downtown groups and external traffic of Nantong present obviously approximate isosceles triangle features,which can explain the conclusion for space distribution structure of external traffic access time in the city.
