nopeusluokat
Nopeusluokat (speed classes) is a Finnish term for a system that groups continuous speeds into discrete ranges for analysis, regulation, and planning. The concept is used in several fields, and the exact definitions of the classes vary by domain and jurisdiction. The aim of speed classification is to simplify communication, enable standardized comparisons, and support decisions in design, enforcement, and operations.
In road traffic engineering, nopeusluokat help determine design speeds for road sections, set speed limits, and
In transport infrastructure and rail networks, speed classes indicate the maximum allowable speeds for track segments
In measurement and data analysis, speed data are collected by radar, lidar, GPS, or loop detectors and
There is no single global standard for nopeusluokat; definitions are established by national authorities and industry
