Abstract: | This paper presents an analysis of accessibility by private transport, using a Hansen type measure of accessibility. The data base is the 1962 London Travel Survey. The study is confined to car-owning households residing in inner London. A comparison of the patterns of accessibility associated with four measures of areal attractiveness - total employment, retail employment, households and population - is presented. The sensitivity of relative accessibilities to marginal changes in parameter values is analysed. Two aspects of the effect of the zoning system on the measurement of accessibility are investigated: the effects of zonal configuration and zonal aggregation. First, the implications of increasing the size of central area zones is analysed. Second, a comparison of patterns of accessibility calculated at the zonal and district levels is undertaken./p] |
