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

All-in-One Toolset

Analyze almost every surface street

Analysis Scope

Planning, design, and operational Level analysis


Easy-to-use and low amount of inputs

7th Edition of of Highway Capacity Manual (HCM)

Compliance to the 7th Edition of HCM

The HCS 2023 release incorporates the recently released 7th Edition of HCM (2022) updates, including:

Connected Automated Vehicles (CAV)

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

Pedestrian Analysis

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

Two-Lane Highways Analysis

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

Model Confidently with the
All-in-One Highway Capacity Software

New Methodology for
Two-Lane Highways Analysis

An entirely new methodology to evaluate the Quality of Service on two-lane highways is included in HCS. The new features of the new two-lane highways are facility segmentation, new performance measures, sensitivity to horizontal curvature, effects of passing lanes, and analysis of Super 2 highways.

New and Improved Methods for Pedestrian Analysis

HCS includes the evaluation of pedestrian crossing safety treatments in two-way stop-controlled (TWSC) intersections and their effects on Pedestrian LOS. It includes, for example: crosswalk markings, median refuges, flashing beacons or school crossing guards.

A Comprehensive Tool with 12 Modules

12 HCS Modules

The Highway Safety Software (HSS) is also included

General Features

Unit Conversion and Metric Unit
HCS2023 fully supports unit conversion from/to metric system, enabling international users to use HCM directly with HCS2023 as well as domestic consultants working on international projects.

User Interface
New menus, logos, and design improvements for an enhanced user experience

Bug Fixes and Improvements
Several improvements based on our users’ feedback and suggestions

CSV Input and Output
A comprehensive CSV input/output functionality enables users to copy/paste data easily to/from external data sources, reducing errors and data entry time.

Analysis and Methods

Analysis of Connected and Automated Vehicles (CAVs)
Users can now model CAVs in the traffic mix for long-range planning analyses as a function of CAV market penetration. HCS implements this impact for freeways (basic, merge, diverge and weave segments, and facility analysis) as well as roundabouts and signalized intersections.

HCM Methods for Pedestrians
Updated analysis at TWSC intersections and uncontrolled crossings. This model can cover 15 types of safety treatments, allowing practitioners to plan for multimodal urban transportation and more livable cities.

Service Volume Tables
New service volume tables, including the impact of CAVs for different freeway segment types.


Updated CSV import/export
Easily import and export CSV data files to facilitate modeling larger corridors

Performance Measures
Vehicle Miles Traveled (VMT) is now available for urban arterials. Emissions and crash prediction model for urban streets, sensitive to signal operations.

Enhanced import from other software
New Synchro-to-Streets file converter available

Two-Way Stop-Control (TWSC)

New calibration parameters for two-way stop-controlled analysis (conflicting flow factors)


Improved roundabout sketch
Accurate representation of bypass lanes included


Measures of Effectiveness (MOEs)
New MOEs for highways, freeways, and arterial modules, including Vehicle Miles Traveled (VMT) and Vehicle Hours of Delay (VHD), and Total Delay Cost.

Map-Based Segmentation
Enables automatic freeway facility creation from Bing Maps

Calibration Table
New calibration page to easily evaluate how model outputs change as function of variations in key model inputs

Freeway Lane-by-Lane Analysis
HCS2023 can model lane-by-lane operational characteristics of freeways, allowing for detailed analysis of Origin-Destination (OD) travel times

Implements New Lane-by-Lane Methodology

Integration with HSS Analysis
HSS safety results included in HCS freeways analysis

Supports New Managed Lane Segment Types

Integrates Reliability Analysis Within Module



Two-Lane Highways Method
A new method for two-lane highways, which allows detailed segmentation of highway facilities, including passing lanes, 2+1 (Super 2) highways, and effects of horizontal alignment

Integration with HSS Analysis
HSS safety results included in HCS highways analysis


HCM Network Method
Captures the interaction between freeways and arterials in estimating operational conditions

Highway Safety Software

Improved User Interface Guidance for Freeway Ramp and Ramp Terminal Analyses
Visual representation of required inputs included for a more intuitive input process

Integration with Freeways and Highways Analyses
Adds the ability to open freeway/highway files directly from HCS

Updated capabilities, including metric unit support, a more intuitive interface, and new freeway graphics
