Pedestrian and transit accessibility on a micro-level

In this paper we connect two notions of accessibility which are more often than not consid- ered separately: pedestrian accessibility and transit accessibility. We move away from the notion of zonal accessibility. Two pedestrian networks are compared to a base-line scenario considering Euclidean distances for a large metropolitan area in which each individual building is considered to be an activ- ity opportunity. It is shown that pedestrian accessibility to jobs differs when pedestrians distances are approximated with different networks. Stop-to-stop public transport travel times are extracted from an agent-based simulation of public transport smart card data. The effect of less than optimal connections to transit to the pedestrian network, a local measurement, can be seen when calculating the accessibility to all destinations in the city. We suggest to move away from Euclidean based distance analyses. Limi- tations can be found in the data available; the connection of buildings to the network becomes important as does the inclusion of pedestrian crossings. For an inclusive accessibility measure it will be necessary to calculate generalized costs for pedestrians and generate different pedestrian networks reflecting the limitations of different user groups.
