Even when origin and vacation spot are the identical, cars and bicycles often take different routes ( Witlox 2007 ). The same brief journey for a car could also be 20-50% longer than for a bicycle (our calculations are based mostly on comparisons per kilometer). The substantial affect of route has been documented in varied monitoring and modeling studies ( Adams et al. 2001 ; Hertel et al. 2008 ; Kingham et al. 1998 ; Strak et al. 2010 ).
