  Changes in travel modes used by people, particularly reduction of the private
car use, is an important determinant of effectiveness of transportation plans.
Because of dependencies between the choices of residential location and travel
mode, integrated modelling of these choices has been proposed by some
researchers. In this paper, an agent-based microsimulation model has been
developed to evaluate impacts of different transport development plans on
choices of residential location and commuting mode of tenant households in
Tehran, the capital of Iran. In the proposed model, households are considered
as agents who select their desired residential location using a constrained
NSGA-II algorithm and in a competition with other households. In addition, they
choose their commuting mode by applying a multi-criteria decision making
method. Afterwards, effects of development of a new highway, subway and bus
rapid transit (BRT) line on their residential location and commuting mode
choices are evaluated. Results show that despite the residential self-selection
effects, these plans result in considerable changes in the commuting mode of
different socioeconomic categories of households. Development of the new subway
line shows promising results by reducing the private car use among the all
socio-economic categories of households. But the new highway development
unsatisfactorily results in increase in the private car use. In addition,
development of the new BRT line does not show significant effects on the
commuting mode change, particularly on decrease in the private car use.
