Nowadays, there are breakthrough developments in the technology of multicopter, which is a remote controlled rotorcraft hovering in the sky. Mounted with a high resolution digital camera, a multicopter can be used to capture images and videos of the road traffic, for deriving the traffic status and queue lengths on highway due to congestion or incidents etc. This makes aerial videography using multicopter an efficient, stable, safe, yet affordable solution for mission-based traffic surveys. It provides an efficient solution if the sites are not covered by CCTV. For urban arterials, accurate trajectories of vehicles can be obtained for the analysis of drivers' behaviors, and information such as spacing, speed, lane-changing etc. can be recorded. We have successfully generated the required dataset for several traffic studies with significant cost reduction. In this paper, we will present the post-processing procedure, limitations, costs and effectiveness, and the quality of collected data for using multicopter for traffic survey.
