The study area is the city of Toronto, Ontario, as indicated in Figure 1, below. This study focuses on existing TTC subway lines and proposed extensions, which are currently all contained within Toronto city limits, as specified by Statistics Canada, 2011. Depicted on the map are the current TTC subway lines, excluding the study’s proposed extensions. By roughly 2060 the population of Greater Toronto Area is expected to double its 2012 population (Toronto Transit Infrastructure Limited, 2012). Given the increasing population of Toronto residents and commuters, increased pedestrian and vehicular traffic are key concerns (Harnack, 2013; Kennedy, 2002). To facilitate the population increase, the transit system must be expanded (Toronto Transit Infrastructure Limited, 2012; Derrible, 2012). In addition to population demands, this study area was selected because all team members possess a desire to improve public transportation systems in the City of Toronto to encourage increased ridership and ultimately reduce greenhouse gas emissions.
