The Highway Capacity Manual provides a comprehensive segmentation framework for freeway analyses. In a facility comprised of multiple segments (basic, merge, diverge and weaving), this framework lists a series of rules on how to determine segment boundaries based on geometric features.
Starting in 2023, the Highway Capacity Software (HCS) now offers a map-based tool where users can easily model long stretches of freeway facilities by placing junction nodes on top of a map. Then, the software automatically calculates all applicable lengths and applies HCM principles for freeway segmentation for a smooth modeling process.
This article discusses some tips and best practices for extracting the best of the map segmentation tool for your studies.
