Travel-time distribution and stochastic decision model. (Left) The travel-time distribution \(p(t)\) in Milan (dots) compared with an exponential interpolation (solid line). The under-expression for short travel-times, with \(t < 4\mbox{ min}\) could be a consequence of the characteristic GPS measurement time and does not affect the time scale \(\langle t\rangle\). The results are consistent with the exponential fit of the tail. (Right) Comparison between the empirical TTE \(p(T)\) distribution in Turin (dots) and the best fit distribution provided by our stochastic decision model, using a logistic threshold function (solid line, see Additional file 1, \(R^{2} = 0.99\)).
