The urban form conditions travel demand in an urban area and, at the opposite, the transportation conditions influence the urban form. This article examines this relationship by presenting a comparative analysis of various indicators of urban sprawl and motorization for Montréal and 11 other urban areas, for the 1960-1980 period. In all the cases studied, the urban sprawl and the motorization appeared as heavy trends. In the Montréal case, these trends have been observed during the last decade, in spite of a relatively weak population growth and it is expected that they will persist in the future.
