The invention discloses an urban ground intersection traffic state alarm method based on links road section matching. The method comprises the following steps: acquiring position information of each intersection of an urban ground road and links road section information; matching is carried out on the basis of road sections between the adjacent intersections and the information of the links road sections, and a path set which corresponds to the road sections and contains the information of a plurality of links road sections is obtained; according to the road section corresponding to the entrance included in each intersection, completing matching and binding of the intersection and the corresponding links road section information; and performing intersection traffic state evaluation based on the link road section information corresponding to the intersection, and giving an alarm when a preset alarm condition is met. According to the invention, a large amount of mixed vehicle links road section information can be accurately matched with the corresponding road section, so that the vehicle links road section information is matched and bound to the corresponding intersection, and the traffic state of the corresponding intersection can be evaluated and alarmed according to the links road section information; while the matching of the road section and the links road section is completed, the track spliced by the links road sections in the path set can approximately reflect the shape of the road section.

    本发明公开了一种基于links路段匹配的城市地面路口交通状态报警方法,包括:获取城市地面道路的各个路口的位置信息以及links路段信息;基于相邻路口间的道路路段与links路段信息进行匹配,得到与道路路段对应的包含若干links路段信息的路径集合;根据每个路口包含的进口所对应的道路路段,完成路口与对应links路段信息的匹配绑定;基于路口对应的links路段信息进行路口交通状态评估,达到预设报警条件时进行报警。本发明可以将大量混杂的车辆links路段信息准确地匹配对应的路段,从而匹配绑定到相应的路口,以便于根据links路段信息对对应路口的交通状态进行评估报警;在完成道路路段与links路段匹配的同时,路径集合内的links路段拼接成的轨迹能够近似反应道路路段的形状。
