Abstract
Systems and methods are provided in which optimized driving trip schedules are generated, optimized, optionally scored according to multiple criteria including fatigue, and provided to a driver or other personnel. Trip schedules are generated from route plans connecting start and end waypoints and optionally intermediate waypoints. Hours-of-service (HoS) regulations and business objectives (fuel efficiency, time-constrained waypoints, etc.) are considered, where a forward greedy algorithm may be used to solve the problem of on-time delivery under such constraints. Driver sleep and fatigue are then determined from the generated trip schedules using sleep prediction models and fatigue prediction models. Trip schedules may then be scored, modified, and optimized in accordance with several other constraints.
