This study evaluates routes followed by residents of the Minneapolis-St. Paul metropolitan area, as measured by the Global Positioning System (GPS) component of the 2010/11 Twin Cities Travel Behavior Inventory (TBI). It finds that most commuters used paths longer than the shortest path. This is in part a function of trip distance (+, longer distance trips deviate more), trip circuity (-, more circuitous trips deviate less), number of turns (+, trips with more turns per kilometer deviate more), age of driver (-, older drivers deviate less), employment status (+, part-time workers deviate more), flexibility in work hours (+, more flexibility deviate more), and household income (-, higher-income travelers deviate less). Some reasons for these findings are conjectured. |
