distanstid

Distanstid is a term used in Norwegian to describe the time required to traverse a specified distance. It is commonly applied in transportation planning, logistics, and route analysis and is analogous to travel time or duration in English. The concept focuses on how long it takes to cover a distance under typical conditions and with a chosen mode of transport.

In its simplest form, distanstid T can be calculated as T = D / v, where D is distance and v is average speed. For routes composed of multiple segments with different speeds, distanstid is the sum of the segment times: T = Σ (D_i / v_i). The result is typically expressed in hours or minutes. When timetables or real-world operation are considered, distanstid can include waiting times and transfers between modes or services.

Applications of distanstid include timetable design, route comparison, and logistics planning. It serves as a key performance indicator for efficiency and reliability, helping planners estimate arrival times, optimize schedules, and allocate resources. In public transport, distanstid informs service levels and customer information; in freight and logistics, it supports routing and delivery commitments.

Several factors influence distanstid, including traffic conditions, weather, terrain, road quality, speed limits, vehicle type, and the number and duration of stops or transfers. Measurement relies on data such as GPS logs, traffic sensors, and timetable data, with accuracy affected by variability and data quality.
