Vehicle Trajectory Observation Based on Traffic Video Provided by Radio-Controlled Model Aircraft

This paper proposes a new approach for vehicular trajectory detecting. A radio-controlled model aircraft is used to shoot live traffic flow videos which can be flexible enough to meet the requirements of various roads conditions. A specific piece of software is created to analyze traffic videos efficiently, which can extract the coordinate of each vehicle from the video and draw the trajectories of those vehicles automatically. The system only produces a relatively small bias, which is allowed in the practical field of traffic engineering. The proposed detection system can not only get the trajectory of vehicle conveniently, but also provide an easy way to collect the data on the velocity and the acceleration of vehicles and, even, set a foundation for driving behavior monitoring and analysis on the roads.
