Enrouteosuus

Enrouteosuus is a term used in Finnish logistics and transport planning to denote the portion of a route that is travelled en route between predefined waypoints, such as depots, hubs or delivery locations. The word combines enroute, indicating the journey in progress, with osuus, meaning share or portion. In practice, enrouteosuus is used to separate the transit segment of a trip from the initial loading and final unloading phases.

Usage and purpose

Enrouteosuus is applied in route optimization, cost allocation, capacity planning and performance measurement. It can be expressed as distance or as time, and may be represented as a share of total trip. The concept helps analysts compare transit efficiency, plan fuel and driver-hours, and assign costs to the main transit portion of a shipment rather than to the entire trip.

Calculation and data sources

Calculating an enrouteosuus relies on route data from GIS or routing software. It is typically defined by two or more designated waypoints and corresponds to the segments of the route that occur between these points, excluding clearly defined first-mile and last-mile operations. The resulting value can be reported in kilometers or hours and may be updated as routes or waypoint definitions change.

Relation to other terms

Enrouteosuus is related to concepts such as enroute time, middle mile, and last mile. It complements overall route metrics by isolating the core transit portion for analysis and planning.
