We present an integrated discrete choice model system of a household's
residential location choice and its members' activity and travel sche
dules. A daily schedule consists of tours, characterised by destinatio
ns, times of day and travel modes. The activity and travel models supp
ly the residential model with an accessibility measure for each househ
old member, namely the expected maximum utility among available daily
activity schedules, conditioned by the chosen pattern of tours and, fo
r workers, the workplace, A nested legit model system is estimated and
applied for Boston. It does not fit the data quite as well as a work-
trip-based comparison model, but its predictions capture additional ef
fects attributable to the more comprehensive accessibility measure.
