This study compares the mobility of teenagers living in Quebec City’s metropolitan area, with an emphasis on the impact of the location on their level of dependent mobility. The presentation combines the results of two studies. First, a 2005 qualitative survey of 30 teenagers aged between 12 and 18 and living in six exurban territories within the Quebec City metro area, which describes their mobility patterns as well as representations of territories, mobility and transportation modes. Second, a quantitative analysis using the 2001 “Origins-Destinations Transportation Telephone Survey” for the Quebec metro area, comparing the mobility of 5784 teenagers according to their residential location (inner-city, postwar suburbs, recent suburbs, exurbs and rural locations). The results of qualitative study indicate that teenagers who live in exurban territories spent several hours a week sitting in a school bus or in the back of their parents’ car (or of other significant adults). Very few teenagers were biking or walking for any utilitarian purposes, or were using public transportation (or had ever tried it). The exurban locations offered few sidewalks and safe biking roads, and efficient public transportation (if any), discouraging or preventing teenagers to walk, bike or use public buses. The quantitative analysis corroborates these findings with no significant differences found according to age or gender. Teenagers without a driving license are more likely to be dependent of school bus or others’ car for their mobility. The level of teenagers’ dependent mobility was found to increase with residential location getting further away from inner-city neighborhoods. Teenagers who live in inner city, postwar or recent suburbs were more likely to be independent in their trips compared with those residing in exurban and rural territories. Living in exurbia generally meant a limited access to nearby retailing services, as well as to institutions and amenities located further away from the house (such as schools, public libraries, public pools and sports facilities), and, as a direct consequence, longer distances to drive on a daily basis. The consequences of dependent mobility on teenagers’ resulting lifestyles as well as cognitive and socio-affective development are discussed.
