Title: A method for detecting traffic anomaly based on travel time distribution with equidistant spatial-temporal division
Inventor: YUCHUAN DU
IPC: G08G1/01
Filed: 2017-12-30
Abstract: Equidistant spatial-temporal division is used in the detection of a traffic anomaly. A spatial-temporal subzone is created by dividing one day into several time segments of 30 minutes, each defined as a time subzone; dividing one implemented area into several spatial segments of 200m x 200m, each defined as a spatial subzone; and defining an intersection of one time subzone and one spatial subzone as a spatial-temporal subzone. Historical and real-time GNSS positioning data of floating vehicles is respectively pre-processed into sampled historical and real-time vehicle travel time data relating to historical and real-time trajectories. These are used in a finite mixed modelling method to establishing respective historical and real-time travel time probability distributions. Jensen-Shannon divergence is then used to measure a difference between said historical and real-time travel time probability distributions and an anomaly index of traffic conditions is determined from said difference. The accuracy of said anomaly index is then evaluated.
