基于GIS的TransCAD在路网节点布局优化中的应用研究
|
摘要
为充分利用TransCAD软件功能进行路网节点布局优化及相关规划研究,克服TransCAD软件在处理图像时繁琐易错的弊端,利用MapInfo软件的分图层路网信息底图并导入TransCAD软件,形成以各收费站为交通小区、以高速公路网为道路网络的TransCAD地理文件。路网交通分配采用SUE分配计算,并通过对理论分配结果与实际交通分析比较,修正路段流量分配结果。按照精准性和高效性原则,进行点位布设。以河南省为例进行了实例分析,合理的布设点位效果显示,单点控制效率较高且车辆控制比例为95.2%,全省范围内的车辆控制率为52.4%。
In order to make full use of the function of TransCAD to optimize the layout of road network nodes, to carry out related planning studies, and to overcome the disadvantage of the cumbersome and error-prone malpractice of image processing,the information base map of the sub-layer road network of MapInfo software was used and imported into TransCAD software to form a TransCAD geographic document with each toll station as the traffic community and the expressway network as the road network. The road network traffic allocation adopted the SUE allocation calculation, and the traffic distribution result of the road segment was corrected by comparing the theoretical distribution results with the actual traffic analysis. Point layout was conducted according to the principle of precision and efficiency. Taking Henan Province as an example, the case analysis was carried out. The reasonable layout of points effect showed that the single-point vehicle control efficiency was higher, reaching 95.2%, and the vehicle control rate in the whole province reached 52.4%.
