Route Choice Efficiency: An Investigation of Home-To-Work Trips Using GPS Data

This paper proposes a new way to study commuting efficiency based on the degree to which actual routes between places deviate from shortest paths. Factors influencing ‘route choice efficiency’ are investigated using a sample of home-based work trips obtained from the Space—Time Activity Research (STAR) survey, which was conducted in Halifax, Canada, between April 2007 and May 2008. The findings indicate that many drivers pursue suboptimal …
