This is how the ETA calculation with PTV Drive&Arrive works
You plan your trips as usual with your route planning software. The finished routes are then transferred to PTV Drive&Arrive, where each trip is assigned a unique number. This so-called SCEM-ID can be passed on to all participants in the transport chain and used to query the ETA.
As soon as the journey begins, either the connected telematics solution or the PTV Driver app automatically transmits the current position data. PTV Drive&Arrive then generates an ETA from this data, the route and traffic information, and all vehicle-relevant attributes and restrictions.
