Evaluating the effects of land use and strategies for parking and transit supply on mode choice of downtown commuters

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.. is 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 Montreal (Canada) region. 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 percent in the transit fee or relative travel time would increase mode split by 10 percent and 3 percent respectively. The effect of age on both mode choice and neighborhood choice is also estimated.. e 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.
