portatour® uses a tested standard speed profile for sales-route scheduling, which largely corresponds to real driving times. In case you recognize during daily use of portatour®, that you regularly deviate from the scheduled journey time, you have the possibility to adapt the speed used in calculations. Adapt your speed on City road, Country road, and Highway to your driving style.
Please note that changes in driving speed lead to re-calculation of travel durations among all customers, which could take several hours depending on server capacity and number of customers. In the meantime, approximate driving durations are calculated on the basis of beelines (see section Unexact beelines have been used for schedule calculation). Therefore, perform such changes thoughtfully.
