Abstract: Described herein is an off-board navigation system for vehicles, comprising at least one operating center and at least one on-board navigation unit installed on board a vehicle, in which the operating center is provided with monitoring means configured for detecting events that modify the road conditions of stretches of road forming part of a road network, and processing means designed to determine, following upon detection of an event, whether said event has occurred on a stretch of road forming part of a route supplied to a user and, in this case, to request an alternative route and determine a point of no return (PNR) that is set along the route supplied to a user and beyond which the vehicle is no longer able to avoid the event and a point of influence (AR), in which the practicability of the route starts to be affected by the onset of the event and beyond which the user is still in time to request and receive an alternative route that will enable him to avoid the event in the case where the point of no return (PNR) has not yet been exceeded.
