针对区域特点修正后的交通优势度评价模型,借助GIS的空间分析、统计功能,以黄淮海平原地区311个评价单元为例,研究了该区域路网密度、交通设施邻近度、区位优势度和交通优势度空间布局。研究发现:黄淮海平原地区交通优势度总体呈偏正态分布,大部分地区交通优势度一般或偏低,优势度较高的地区有京津及其周边地区,以及以京津为核心辐射出的三条交通优势带。
Aiming at the modified traffic dominance evaluation model based on regional characteristics, taking the spatial analysis and statistical functions of GIS as an example, taking 311 evaluation units in the Huang-Huai-Hai Plain as an example, this paper studied the influence of road network density, traffic facilities proximity, location dominance and Traffic advantages degree spatial layout. The study found that the overall traffic dominance in the area of Huang-Huai-Hai Plain is generally normal distribution, the traffic dominance in most areas is normal or low, the areas with higher dominance are Beijing-Tianjin and its surrounding areas, and the radiation centered at Beijing-Tianjin The three traffic advantages belt.
