This study challenges the widely applied shortest path assumption by evaluating routes followed by residents of the Minneapolis - St. Paul metropolitan area, as measured by the GPS Component of the 2011 Twin Cities Travel Behavior Inventory. It finds that most travelers used paths longer than the shortest path. Some reasons for this are conjectured.enRationality, Route Choice, User Equilibrium, GPS Study, Travel Behavior, NetworksAn empirical study of the deviation between actual and shortest travel time pathsWorking Paper
