Abstract: Stimulating physical activity through active transportation is now a most relevant topic in urban planning with regard to public health. Indeed, half of teenagers in the province of Quebec do not reach the recommended level of physical activity to positively impact their health. Walking and biking have been identified as potential resources to increase physical activity. In this context, this thesis in urban planning and regional development combines quantitative, qualitative and spatial approaches in order to examine the share of active transportation in the daily mobility of teenagers and the influence of the built environment in increasing it. The thesis is supported by three types of analyzes: the 2001 origin-destination survey among 5784 adolescents in the Quebec City metropolitan area, an Internet survey with 173 fourth year high school students from five schools in the Quebec metro area, and by online trip and daily activity logs completed by 40 of the 173 adolescents. The results show a high dependency on motorized transportation which was found to be closely related to the location of the home, school, and to the geographical dispersion of the places they visit. The decision to attend a high school for its good reputation or a specialized program seems to be made without much concern to the long travel distance from the home and heavy reliance on motorized transportation it may generate. The results also show that teenagers walk to a greater number of places in the vicinity of their school compared to their home. Urban form and land use are playing active role in stimulating walking around schools, namely the presence of sidewalks, street connectivity and the presence of shops with low nutritional quality food supplies. Analyzing teenagers’ perceptions of what is a walkable street revealed that the speed and density of motorized traffic stand as barriers against walking. Their effective action space reached by foot around the school was found to be more reduced than what the delimitation of walkable districts around the home used in most of the reviewed studies. Finally, their global weekly action space were classified into a typology which is discussed in relationship to the distances they travel, their use of active transports, their household characteristics, their attachment to their neighborhood and finally, their perception of transport modes.
