Preloading is when a vehicle starts its plan already loaded and can depart from its start location immediately.
The following conditions are required to allow a vehicle to preload at a location:
When preloading occurs, no pickup service times and load time are incurred for the initial sequence of pickups. Site time is incurred as normal. This is because site time is intended for modelling activities that the driver needs to undertake regardless of whether the vehicle is preloaded or not (e.g. paperwork, briefings or safety inspections).
The number of vehicles that can be preloaded at a location is not restricted by the number of loading bays at that location.
