We estimate the effects of urban forms measures in relation to average commuting time and distances within French urban areas in our cross-sectional analysis from 1999 to 2014. In addition, the effects of the spatial distribution of jobs and dwellings in relation to average commuting time during peak-hours and to urban cores are estimated in 2014. The greater geographical concentration of jobs in urban areas with respect to the population seems to significantly influence commuting time and distances. Density and distribution of employment locations may manage urban congestion. However, our estimates suggest relatively modest effects. In addition, our results demonstrate that commuting time and distances depend also on other parameters than the spatial distribution of jobs within urban areas (population density, demography, public transport, etc.).
