The invention discloses a traffic zone division method based on a travel gravity model, and the method specifically comprises the steps: carrying out the region splitting of a map, and obtaining minimum region blocks; extracting origin and destination points in the trajectory data, and constructing an OD data set; extracting travel hotspots according to the OD data set; matching the travel hotspot with the minimum area block to obtain a travel hotspot group of the area block; and constructing a travel gravitation model based on the minimum area blocks and the travel hotspot group, and merging the minimum area blocks according to the travel gravitation model to obtain a traffic zone. The traffic cell division method provided by the invention does not need manual correction, only depends on map data and trajectory data, depends on an ArcGIS platform and a rasterization technology, combines influences of a map and travel OD on the traffic cell to consider, constructs a travel gravitation model based on a minimum region block and a travel hotspot group, and improves the traffic cell division efficiency. The objective and accurate traffic zone division method is formed, and conditions are provided for analysis and prediction of traffic travel characteristics.
本发明公开了一种基于出行引力模型的交通小区划分方法,具体包括:对地图进行区域拆分,得到最小区域块;提取轨迹数据中的起讫点,构建OD数据集;根据OD数据集,提取出行热点;将出行热点与最小区域块进行匹配,得到区域块的出行热点组;构建基于最小区域块与出行热点组的出行引力模型,根据出行引力模型合并最小区域块,得到交通小区。本发明所提供的交通小区划分方法无需进行人工修正,只依赖于地图数据和轨迹数据,依托ArcGIS平台与栅格化技术,将地图和出行OD对交通小区的影响结合起来考虑,构建基于最小区域块与出行热点组的出行引力模型,形成一种客观、精确的交通小区划分方法,为交通出行特征的分析与预测提供了条件。
