determine, with range measurements between one or more vehicle beacons installed on an end of a vehicle and configured to communicate with one or more guideway beacons positioned at predetermined locations along one or more guideways, after the processor wakes from a sleep state, vehicle position and guideway occupancy to determine a change in the vehicle position from before the processor entering the sleep state;
determine, with the range measurements between the vehicle and the guideway beacons, a periodic vehicle position update;
determine, with the range measurements between the vehicle and the guideway beacons, a vehicle speed and a vehicle direction of motion on the guideway;
