The invention relates to the technical field of big data analysis, in particular to a road traffic data analysis system based on big data, and the system comprises a traffic data collection module which is used for obtaining the traffic flow and speed corresponding to each staggered intersection and each non-staggered intersection in a road distribution diagram, and the length of a connection section of the staggered intersections; the data interval acquisition module is used for acquiring a plurality of intervals according to the abscissa and the ordinate of each staggered intersection; the K value obtaining module is used for obtaining the K value of each data point in each interval according to the density degree of the intervals; the abnormal degree obtaining module is used for obtaining the abnormal degree of each data point in each interval; and the abnormal data point acquisition module is used for acquiring abnormal data points so as to obtain the dislocation intersection to be optimized. According to the method, the detection efficiency and accuracy of the abnormal data points are improved, so that the dislocation intersection corresponding to the abnormal data points can be optimally designed in a targeted manner for the dislocation intersection with the most obvious hidden danger.

    本发明涉及大数据分析技术领域,具体涉及基于大数据的公路交通数据分析系统,包括:交通数据采集模块,用于获取道路分布图中每个错位交叉口和每个非错位交叉口对应的车流量和速度,错位交叉口的连接路段长度;数据区间获取模块,用于根据每个错位交叉口的横坐标和纵坐标得到若干区间;K值获取模块,用于根据区间的密集程度得到每个区间内每个数据点的K值;异常程度获取模块,用于得到每个区间内每个数据点的异常程度;异常数据点获取模块,用于获取异常数据点进而得到待优化错位交叉口。本发明提高异常数据点的检测效率和准确性,从而便于对异常数据点对应的错位交叉口,有针对性的对存在隐患最明显的错位交叉口进行优化设计。
