1. A method, comprising:
receiving, with a controller, information associated with a first haul truck configured to traverse a travel path extending from a paving material plant to a worksite, the information including a haul truck identifier unique to the first haul truck;
identifying, with the controller, the first haul truck as having a location sensor that is one of not disposed on the first haul truck and faulty;
determining, with the controller, whether a second haul truck traversed the travel path ahead of the first haul truck; and
based at least in part on determining whether the second haul truck traversed the travel path ahead of the first haul truck, determining, with the controller, an arrival time at which the first haul truck is expected to arrive at the worksite, wherein the arrival time is determined based at least in part on
an estimated travel time associated with the first haul truck traversing the travel path, or
a recorded travel time associated with the second haul truck traversing the travel path ahead of the first haul truck.
