SingleLane-InnerRingWestLine-Expressway

The data were collected on the Nanjing Inner Ring West Line, an elevated segment of Nanjing’s urban expressway network. The study section is configured as a two-way, two-lane roadway, with one lane per direction, meaning that lane-changing maneuvers are not possible within the observed area. Traffic videos were simultaneously captured by two UAVs and then stitched in post-processing to obtain continuous vehicle trajectories over a road segment of approximately 700 m. Three independent data-collection sessions were conducted, denoted as AD, BE, and CF, respectively.
