1. Which cruise speed burns the least fuel per tonne-kilometre? The sweep drives one loaded truck at every speed from 30 to 110 km/h with the full model and compares it with the closed-form optimum (fuel only, and fuel plus driver and truck time).
2. How short can the time gap be before the convoy becomes an accordion? Ten trucks follow a lead truck that wobbles at the worst frequency. The sweep measures the amplification per truck against the string-stability criterion.
3. How many trucks does the supply line need? An event simulation of the loading bays, the road and the unloading bays for 1 to 40 trucks, compared with Little's law and the bay limits.
Press a button. The current truck, surface, payload and supply-line settings are used (flat road, no wind, no slipstream for experiments 1 and 2).
