Characteristics of multilane traffic flow from aerial data
Over the past few years, the Federal Highway Administration has collected aerial traffic flow data by time-lapse photography with a helicopter-mounted camera. The raw car trajectories developed from this data base are discrete in time. In this study, a methodology was developed to produce continuous car trajectories from the discrete data base, i.e., the data base thus obtained gives location, speed and acceleration as a continuous function of time. These continuous car trajectories were then used to develop some microscopic and macroscopic characteristics of multilane traffic flow
