Cependant, certains inconvénients, comme la présence de fortes intempéries, mettent un frein à son développement. Le but de ce rapport est d’étudier l’influence des différentes conditions météorologiques sur l’utilisation du vélo (aux niveaux journaliers, heures, saisons,..). L’étude se porte sur Helsinki en 2016 et prend en compte deux sources de données : le système de vélo en libre- service et le comptage automatique de vélo. Ce rapport présente divers résultats permettant une meilleure compréhension de l’influence des conditions météorologiques sur l’utilisation du vélo et suggère des améliorations possibles pour les plans de déplacement urbain. ABSTRACT Cycling, as a zero emission vehicle, is a relevant transport mode concerning sustainable development. Bicycle use is increasing as development of cycling infrastructures and introduction of bicycle sharing system are made through cities. However, cycling still has many restriction such as being dependent of the weather conditions. The aim of this study is to assess how weather influences bicycle use from different perspective (e.g. depending on time periods and weather attributes). Empirical research is conducted in Helsinki in 2016 with two different data sources - the bicycle sharing system and the automatic bicycle counter systems. The report presents main findings, which are further discussed and reasoned; and practical implications in improving planning cycling infrastructure and promoting bicycle use are made. 2 Acknowledgment I would like to thank first my supervisor, Olle JARV, for his continuous help along the internship. I would also like to thank two colleagues in particular in the Digital Geography Lab in the University of Helsinki, Enrico Di Minin and Maria Salonen, who helped me have a better understanding of my work. I would also like to thank Patricia LEJOUX, Julie PELATA, and Jean-Pierre NICOLAS, as respectively the presidential jury, the expert and the representative of my master VEU, for their participation in the jury. 3 Contents Analytical notice ................................................................................................................................................ 2 Acknowledgment
