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.

HCS 2024 Main Menu

Upgraded UI in Freeways Module

The Freeways module brings several upgrades in its user interface (UI) to facilitate the data input process, including:

  • Mapping tool now saves node coordinates, allowing the user to revisit their inputs as much as needed
  • New input for “Ramp Demand” on the data grid, facilitating data input for large facilities
Horizontal curvature modeling - Two-lane Highways

Queue Lengths in ft.

The Stop-Controlled Intersections and Roundabouts modules now include a new output for back-of-queue length measured in feet. This feature was previously available only for signalized intersections, but was expanded to other intersections to address our users’ needs.

Improved User Experience

Added Undo/Redo Features

For Freeways, Highways, Freeways Reliability, Service Volumes, and Network Modules

Added Global Inputs to Highways

Past Update Highlights

7th Edition of of Highway Capacity Manual (HCM)

Compliance to the 7th Edition of HCM

The HCS 2024 release incorporates methodologies from the 7th Edition of HCM (2022) updates, including:

Can assess the impact of CAVs on signalized intersections, roundabouts and freeways for planning-level applications (e.g., 25 years planning period)

Enhanced pedestrian analysis at two-way stop-controlled intersections and crossings.

New method with wide application for analysis of two-lane highways
