Abstract
Technologies are disclosed that determine when alternative routes are to be pre-generated for a vehicle. A route planning system receives a request for a navigation route for a vehicle. The navigation route is generated, where the navigation route includes navigation nodes. For a given navigation node, a corresponding weight and/or a probability of an exception event occurring are determined, and are used to determine whether to generate an alternate route configured to be utilized in response to a future detection by the vehicle of an exception event associated with the given node. The route planning system may then generate alternate routes accordingly, and may transmit the navigation route and an alternate route for a corresponding given node to the vehicle. The navigation route may be used to navigate the vehicle, and the alternate route may be used to navigate the vehicle if an exception event is detected.
