The invention discloses a road network basic data-based region boundary key traffic flow direction category identification method, which comprises the following steps of: setting lane coordinates, shifting different lanes according to lane types, and calibrating a starting point and an end point; disassembling the target area into a plurality of small areas according to lines and polygons; determining a starting point position; determining an end point position; according to the starting point position and the end point position, the inflow direction, the outflow direction and other directions are judged to serve as the region boundary traffic direction category of the target region; and identifying a target area boundary key intersection and a key flow direction of the target area boundary key intersection. The method of the invention is based on road network basic data, automatically determines each traffic flow category of the area boundary, identifies the key intersection of the area boundary, reduces the workload of flow direction manual configuration, provides flow direction category data support for area control, identifies the key intersection and the key flow direction of the area boundary, and improves the traffic flow distribution efficiency. And portal control can be conveniently carried out through the regional boundary intersection to relieve regional congestion.

    本发明公开了一种基于路网基础数据的区域边界关键交通流向类别识别方法,包括:设置车道坐标,对不同车道按照车道类型进行偏移,并进行起始点和末点的标定;将目标区域按照线条和多边形,拆解为多个小区域;确定起始点位置;确定末点位置;根据起始点位置、末点位置,判定流入流向、流出流向及其他流向,作为目标区域的区域边界交通流向类别;识别目标区域边界关键路口及目标区域边界关键路口的关键流向。本发明的方法基于路网基础数据,自动判定区域边界的各股交通流类别,辨别区域边界的关键路口,减少流向人工配置工作量,为区域控制提供流向类别数据支撑,识别区域边界关键路口和关键流向,便于通过区域边界路口做门户控制缓解区域拥堵。
