The invention provides a road section bypassing behavior identification method based on bicycle track data, which comprises the following steps: 1) obtaining and cleaning bicycle track data, and tracks needing to be cleaned have tracks with low sampling rate and abnormal speed; 2) map matching: projecting each track to a corresponding road network to realize map matching; 3) one-way road detouring judgment: considering detouring track characteristics, judging detouring behaviors according to a geometric detouring form, and on the basis, adding road attribute factors for further judgment; and 4) detour behavior frequency grade division: counting the frequency of detour events of each road section in a week, dividing into three grades by frequency panes, and marking the road sections on the OSM map platform by using different colors to represent the detour severity degree. According to the method, the detour behavior is judged through map matching and geometric methods, and the detour detection precision is effectively improved.
本发明提供一种基于自行车轨迹数据的路段绕行行为识别方法,包括如下步骤:1)自行车轨迹数据的获取与清洗,需要清洗的轨迹有采样率低以及速度异常的轨迹;2)地图匹配:把每一条轨迹投影到对应的道路路网,实现地图匹配;3)单向路绕行判定:考虑绕行轨迹特征,根据几何学上的绕行形式对绕行行为进行判定,在此基础上,加入道路属性因素做进一步判定;4)绕行行为频次等级划分:统计一周内各路段的绕行事件的频次,并以频次窗格划分三个等级,分别用不同颜色在在OSM地图平台上对路段进行标记表示绕行严重程度。本发明通过地图匹配和几何学方法判断绕行行为,有效提高了绕行检测的精度。
