| Abstract: | Instantaneous traffic information can be collected by the Floating Car Data(FCD) method.Based on the establishment of Shenzhen Urban Transportation Simulation System(SUTSS),the paper explored how to use taxis as the data collection sensors in Shenzhen.Due to the nature of FCD,continuous GPS data such as routing velocities and coordinates can be collected by any GPS equipped vehicle.Therefore,relevant algorithms are developed and utilized for the map-matching according to probability and statistical theories... |
