A Real-time Traffic Status Identification Method Based on Floating Car Velocity
摘要
Abstract
This paper presents a traffic status identification method, which is consistent with the fluctuation of traffic conditions. Based on the analysis of floating car data, the consideration of the influence of traffic impedance and critical frequency hopping, the result of discrimination of traffic status is optimized by pre-discrimination and double revisions. This methodology can effectively filter out the abnormal distortion of traffic status parameters around the threshold value, and in the mean time modify the phase step of traffic status caused by abnormal data. Thus, the results of discrimination can be optimized. This research establishes a applicable system based on the methodology. By examining the multiple indexes, it promotes the accuracy of the results.关键词
