Urban Traffic Analysis through an UAV
2014
Abstract In order to realize a precise and accurate traffic study, a method to evaluate the real traffic flow conditions in urban areas based on videos acquired by an UAV, Unmanned Aerial Vehicle, is proposed. In this way it does not require additional equipment 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 have been compared to experiments using macroscopic simulation models and the eventually differences have been discussed.
An integrated package for modelling and mapping urban traffic emissions and air and acoustic quality
2005
Urban activities and traffic movements have an important impact on the acoustic level and air pollution. The aim of the present paper is to assess the improvement of an environmental territorial information system, developed in 2003, useful as a decision support for town-planning and territorial management. The system born as a data base and as a tools of management for environmental problems is now improved and is able to calculate the noise levels and the correlate CO values. Since an urban area could be analyzed at a macro-scale level also the evaluation is at a macro scale level. Thanks to its flexibility, the modular system allows to meet the demands of a wide range of applications.
