Disclosed are various embodiments that extract vehicle trajectories from aerial videos. A vehicle track comprising pixel coordinate points is obtained. The pixel coordinate points are converted to relative coordinate points. At least one vehicle trajectory is extracted based at least in part on the vehicle track and the relative coordinate points. A lane structure is generated that is based on the at least one vehicle trajectory.
