Abstract

Metropolitan regions around the world are looking for sustainable strategies to reduce motor vehicle traffic congestion, energy consumption and emissions. These strategies include land use policies as well as improvements to public transit services. This empirical work aims at studying the potential impact of land-use (LU), public transit supply (PT) and parking pricing strategies on the mode choice of commuters living in the commuter rail line catchments in the region of
Montreal, Canada. It makes use of an econometric modeling approach with both transportation mode choice and neighborhood type choice, as simultaneous decisions in order to take into account the endogeneity of these choices. The neighborhood choices are represented by
neighborhood typologies derived from a cluster analysis using land use and transit supply indicators (population density, land use mix and bus transit supply). As part of the outcomes of this study, the elasticities of mode choice with respect to commuter-transit fees, travel time reductions and hourly parking costs are estimated. From the results, it is observed that a reduction of 10% in the transit fee or relative travel time would increase mode split by 10% and 3% respectively. The effect of age on both mode choice and neighborhood choice is also estimated. The individual and household structure factors associated with mode choice and/or residential neighborhood choice are also identified. Commuter age affects both outcomes. Income and gender affect mode choice while car ownership and the presence of children are linked to neighborhood choice.
