Abstract


Traffic flow prediction is a basic research project of urban traffic management research . Along with the popularization and application of the GPS / GIS technology , the floating car technology is becoming a new hot spot in the field of traffic flow study . The flow is one of the main parameters of the traffic flow , which reflects the traffic load in a smaller period of time , is one of the important data in accordance with the Urban Traffic Guidance . Hangzhou taxi car GPS system data base data , carried out a study on the urban road traffic volume projections . Paper collection of traffic flow and floating car , the applications floating car 's position and speed information , speed fitting to get the cycle interval speed and traffic flow characteristic velocity . Sections for intersection signal flow characteristics of non- interference flow assumptions , the use of the traffic wave theory to describe the urban sections of the traffic flow cycle process . Traffic flow of the traffic flow by dissipating stage and interference-free flow phase ( ground state ) two separately established traffic flow projections based on the flow equation and the floating car data model and parameter calibration method . Hangzhou floating car GPS data model example , to verify the validity of the model .
