Cycle Time

Cycle time is defined as the time for a truck to complete one return trip between any two points on the haul.

Note that Michelin provides a temperature coefficient for calculating TKPH at different temperatures. This coefficient can sometimes be negative if the average haul speed is below 5 kilometres per hour. Essentially this means that there are no TKPH delays.
