Delivering modal-shift incentives by using gamification and smartphones: A field study example in Bogota, Colombia

Statistical analysis of the data showed that, even though there was an observed percentage change in mode choice from week 1 to week 2 towards higher incentivised modes (i.e. cycling and walking), the change is not statistically significant and therefore cannot be attributed to the incentives delivered during week 2. Furthermore even though there was an increase in the total time and distance recorded by the entire group of subjects (from 498.7 km and 32.5 h during the first week to 799.9 km and 58.5 h during the second week), the subjects did not alter their travel patterns significantly.
