摘要
针对基于固定检测设备的高速公路拥堵检测方法在检测时间和检测范围方面的不足,提出了基于浮动车GPS数据的检测方法。提出了完整的拥堵检测流程,包括高速公路的区间划分、GPS匹配、区间状态判定和拥堵状态仿真等环节。通过检测案例分析说明了方法效果。在拥堵检测的快速性、准确性和全面性方面较之传统方法有明显优势,同时分析了此方法的具体应用条件。
The traditional expressway traffic congestion detection method has a long detection time and limited detection range.To deal with this problem,a new method of expressway congestion detection based on probe car GPS data was proposed.The expressway interval division,GPS matching,interval state judgement and congestion status simulation were included in this method.The effectiveness of the method is verified by a detection case.Compared with the traditional methods,the advantages of this method are obvious in detection time and accuracy.Moreover,the application condition of this method was presented.
