Urban traffic analysis through an UAV

In order to realize a precise and accurate traffic study, a method to evaluate the real traffic flow conditions in urban areasbased on videos acquired by an UAV, Unmanned Aerial Vehicle, is proposed. In this way it does not require additionalequipment to earth and, not being invasive, does not influence the driver behavior.This paper presents the results obtained in terms of vehicular traffic flow along a way in the city of Palermo. The results havebeen compared to experiments using macroscopic simulation models and the eventually differences have been discussed.
