The invention provides a real-time road condition analysis method and system, and the method comprises the steps: obtaining the original vehicle passing data of each intersection, calculating the traffic flow of a road segment formed by adjacent intersections, carrying out the grading of the traffic flow of the road segment, and writing the information of each road segment into a database; acquiring traffic flow and passing time from a starting intersection to an ending intersection of the predetermined road section, and calculating fast average time, slow average time and average passing time of the predetermined road section; calculating the ratio of the average passing time length of the current preset road section to the historical rapid average time length, comparing the ratio with a preset road section smoothness coefficient and a road section congestion coefficient, setting a corresponding road condition field value according to the comparison result, displaying the road condition of the road section on a map according to the road condition field value, and when the road condition state is changed, displaying the road condition on the map according to the road condition field value. And updating the road section traffic data. According to the scheme, real-time processing and analysis of crossing vehicle passing data can be realized, and the accuracy and reliability of road condition analysis can be guaranteed.

    本发明提供一种实时路况分析方法及系统,该方法包括:获取各路口原始过车数据,计算相邻路口构成的路段的车流量,对路段流量进行等级划分后,将各路段信息写入数据库中;获取预定路段起始路口至结束路口间的车流量和通行时间,计算预定路段的快速平均时长、慢速平均时长和平均通过时长;计算当前预定路段的平均通过时长与历史快速平均时长的比值,将所述比值与预设的路段畅通系数、路段拥堵系数比较,根据比较结果设置对应的路况字段值,根据路况字段值在地图上显示路段路况,并在路况状态发生变更时,更新路段通行数据。通过该方案可以实现对路口过车数据的实时处理分析,并能够保障道路路况分析的准确性、可靠性。
