“…The reconstructed trajectory is the straight passing line to vehicles with specific entry and leaving points, such as vehicle 4. For vehicles with one exact passing point, such as vehicles 5 and 7, the travel speed is formulated by the speed-density model 26 , where v f is the free flow speed, and α = 1.0, β = 0.05 according to relating researches 27 , 28 . In this way, the travel speed is given based on the local density, representing the road segment’s traffic dynamic.…”

Despite abundant accessible traffic data, researches on traffic flow estimation and optimization still face the dilemma of detailedness and integrity in the measurement. A dataset of city-scale vehicular continuous trajectories featuring the finest resolution and integrity, as known as the holographic traffic data, would be a breakthrough, for it could reproduce every detail of the traffic flow evolution and reveal the personal mobility pattern within the city. Due to the high coverage of Automatic Vehicle Identification (AVI) devices in Xuancheng city, we constructed one-month continuous trajectories of daily 80,000 vehicles in the city with accurate intersection passing time and no travel path estimation bias. With such holographic traffic data, it is possible to reproduce every detail of the traffic flow evolution. We presented a set of traffic flow data based on the holographic trajectories resampling, covering the whole city, including stationary average speed and flow data of 5-minute intervals and dynamic floating car data (FCD).
