This paper was presented at Session 26 - Transport Planning Techniques 1. Census journey-to-work data supplemented by road network data are analysed for 30 Canadian census areas. Per capita homework travel increases with census area population but at a decreasing rate. Most of the observed variation in per capita travel between areas is explained by mean trip length and mean labour participation rate. While the mean trip length increases with census area population there are significant deviations from the trend. The principal factors influencing these deviations are geographic variation and the concentration of employment. Labour participation rates are analysed at the census tract level for each census area. Most of the observed variation in census tract labour force is explained by the dwelling unit composition in each census tract rather than aggregate census tract population or household magnitudes. An attraction unconstrained gravity model incorporating an inverse power function is calibrated for all census areas. This simple gravity model explains from 54 to 94 per cent of the observed variation in home-work interactions. Relationships between the gravity model exponents and census area population are explored (a). (TRRL)
