Commute minimization in the Greater Toronto Area: applying a modified excess commute

Abstract Following the excess commuting literature, we develop a benchmark measure of the minimum required commute, conditional on the layout of the specific urban area. Through segmentation of the commuters into those that can be relocated and those that cannot, we try to explain the difference between the minimum required and actual commute. To determine the segmentation of the commuters we make use of a micro-level explanatory model of commuting distance. This micro-level modeling exercise informs a number of excess commuting simulations that address the contribution of certain groups of commuters to total commuting. Findings from the micro-analysis reaffirm similar findings in the literature for other urban areas. The simulation exercise suggests that varied levels of commute savings may result from policy directed at particular commuter groups.
