Abstract Air pollution and road traffic noise are two important environmental nuisances that could be harmful to the health and well-being of urban populations. In Mexico City, as in many North American cities, there has been an upsurge in bicycle ridership. However, Mexico City is also well known for having high levels of noise and air pollution. The purpose of this study is threefold: 1) evaluate cyclists’ exposure to air pollution (nitrogen dioxide) and road traffic noise; 2) identify local factors that increase or reduce cyclists’ exposure, in paying particular attention to the type of road and bicycle path or lane… More >

Abstract In this paper, we propose a model and a methodology for the analysis of urban fabrics, sets of built morphological units articulated together by urban networks. The core of the paper presents the MoGUS model (Model Generator & analyser for Urban Simulation) and its formalization. This model jointly represents the buildings and the viaires networks of a city in a graph, and allows a comparative analysis of the properties of different urban fabrics, using derived indicators. A study plan applied to four types of archetypal urban fabrics (Hippodamean, medieval, radio-concentric, Haussmannic) generated with the MoGUS tool is presented to illustrate… More >

Abstract The research presented in this paper introduces a qualitative approach for the representation of urban sound scapes. The approach combines a series of in situ psychoacoustics measurements recorded with different sensors with a qualitative evaluation derived from human beings acting in these urban environments. The experiments realized in the city of Sidi Bou Saïd illustrate the potential of the combination of the quantitative and qualitative views, as well as demonstration of the feasibility of the whole approach when experimented in a real urban environment.

Abstract In this paper we experiment an approach allowing to produce a coherent land use and cover of rangelands in the French Mediterranean areas represented by the Occitania and Provence-Alpes-Côte d’Azur regions. Four different data sources are used: the OSO land use and cover (OSO), the Registre Parcellaire Graphique (RPG), the BD-Forêt V.2.0 and Sentinel 2 L3A satellite data. The RPG of 2019 and the BD-Forêt updated in 2018 were used as the main source of reference data for training the models to classify the OSO 2019 low F-score class objects, after extraction of the reflectances, spectral and textural indices variables… More >
