Highway Capacity Software 2023
The reliable software tool that faithfully implements the methodologies from the Highway Capacity Manual
Version Release
New in HCS 2024
The new version of the Highway Capacity Software (HCS) is available from January 2024. The software is updated annually to improve functionality and incorporate updates from the Highway Capacity Manual. Explore the latest additions and features added to the new version release.
Improved User Experience
Past Update Highlights
Network Module
A new module that implements chapter 38 of the 7th Edition of the Highway Capacity Manual. The network analysis will allow the user to combine interacting arterial and freeway models for the first time. Features include:
- Performance measures for trips over multiple facilities
- On-ramp and off-ramp spillback check
Map-Based Segmentation for Freeways
HCS Freeways module will include a new tool for segmenting freeway facilities on a Bing Maps background, classifying resulting segments according to the HCM methodology for freeways. The map segmentation tool promotes modeling efficiency while ensuring HCM segmentation compliance.
Integrated HCS and HSS Analysis
New input file compatibility between HCS and HSS enables integrated operations and analyses for highways and freeways, including:
- Ability to open HCS freeway/highway files directly in HSS
- HSS safety results may be included in HCS highways and freeway analysis
Compliance to the 7th Edition of HCM
The HCS 2024 release incorporates methodologies from the 7th Edition of HCM (2022) updates, including:
