Identification method for road occupation behavior of pedestrian on the basis of bicycle sharing GPS (Global Positioning System) trajectory data

Abstract

The invention discloses an identification method for road occupation behavior of a pedestrian on the basis of bicycle sharing GPS (Global Positioning System) trajectory data. The method comprises thefollowing steps that: firstly, carrying out bicycle sharing GPS trajectory data cleaning to remove abnormal speed trajectory data and low-sampling-point trajectory data; then, carrying out map matching and processing on the bicycle sharing GPS trajectory data; matching the bicycle sharing GPS trajectory data to a road to extract GPS trajectory point characteristics, and on the basis of trajectorygeometric characteristics, correcting the bicycle sharing trajectory data to remove the trajectory data of reverse riding; and finally, detecting the road occupation behavior of the pedestrian, calculating a calculation deviation value between a trajectory to be detected and a standard trajectory, carrying out fitting calculation on deviation value distribution, and using Kolmogorov-Smirnov to check and judge whether the road occupation behavior of the pedestrian occurs in the road section or not. By use of the method, the advantage that the GPS trajectory data is real-time and effective can be fully utilized, the timeliness and the effectiveness of an identification process can be achieved, and manpower, material resources and financial resources are saved. The road occupation behavior ofthe pedestrian is identified in time and can be intervened in time, and the traffic safety level of pedestrian passage and non-motor vehicle riding can be improved.

Description

technical field [0001] The invention relates to a method for identifying pedestrian encroachment on road behavior, in particular to a method for identifying pedestrian encroachment on road behavior based on GPS track data of shared bicycles. Background technique [0002] Pedestrian encroachment on the road is a common traffic phenomenon, especially the mixed traffic of pedestrians and non-motorized vehicles is very common. On the one hand, it affects the passing and riding speed of pedestrians and non-motorized vehicles, which is likely to cause congestion of non-motorized lanes and reduce traffic efficiency; In order to fully curb this traffic phenomenon, how to distinguish pedestrian encroachment on the road is the foundation and key. At present, the identification of pedestrian encroachment on the road is mainly realized through on-site judgment and off-site video observation, which requires a lot of manpower and material resources, and the real-time performance is poor ...
