Urban spatial structure, transport mode and space-time constraints are known to affect accessibility to activities for a city’s residents. However, most studies consider space and time to be static, by measuring accessibility from home and at one point in time. Moreover, most studies report accessibility in terms of the number of activities accessible in a given travel cost. Such studies neglect the mobility and time budget constraints on people’s accessibility. Furthermore, modal accessibility disparity studies have not considered inequality between modes during the afternoon commute. We examine accessibility to several non-work activities by automobile and public transport using a spatiotemporal measures that determines the number of minutes people have available to participate in activities, given a fixed time budget, rather than simply the number of activities. We seek to discover by how much accessibility to non-work activities differs by mode and time budget within the Warsaw, Poland metropolitan area. Our calculations are based on a very detailed travel time model for automobiles and public transport that include congested travel time during the afternoon rush period, walk times to and from public transport stops, and time spent searching for a parking spot.
