The invention relates to a real-time road condition information processing method, which comprises the following steps of: performing gridding processing on road network data by adopting longitude and latitude grids, quickly searching based on the gridding road network data to find a road section containing positioning data, matching the direction of the positioning data with the direction of the road section, and finally obtaining the road section with the most accurate positioning data. And road condition calculation is carried out according to the instantaneous traffic flow and the vehicle speed in the road section. According to the invention, the processing speed and accuracy of positioning data are improved, and real-time road condition information can be reflected faster and more accurately.
本发明涉及一种实时路况信息处理方法,首先采用经纬网格对路网数据进行网格化处理,然后基于网格化路网数据的快速搜索,找到包含定位数据的路段,之后对定位数据的方向与路段方向做匹配,最终得出定位数据最准确的路段,并根据路段内的瞬时车流量及车速进行路况计算。本发明提高了定位数据的处理速度和准确度,可更快、更准确的反应实时的路况信息。
