|1. (WO2018122585) METHOD FOR URBAN ROAD TRAFFIC INCIDENT DETECTING BASED ON FLOATING-CAR DATA|
XU, Michael Jun
|Title:||METHOD FOR URBAN ROAD TRAFFIC INCIDENT DETECTING BASED ON FLOATING-CAR DATA|
A method for urban road traffic incident detecting based on floating-car data can use on-board GNSS positioning devices of floating cars to acquire the space position information of the floating cars at different time, and therefore, can achieve the intelligent detection of urban road traffic incidents by analyzing and mining the massive floating car track information. The urban road traffic incident detection technology uses the probability distribution of travel speed to characterize traffic conditions, uses the measurement index of difference in probability distribution to reflect the difference in traffic conditions, thereby having the advantages of clear principles, being easy to implement, and having a high detection rate.
