Industry Standard for Macroscopic Traffic Analyses
HCS is a robust macroscopic traffic simulation tool designed for transportation professionals to conduct surface road analyses and assess the operational performance of almost any surface street. Trusted by transportation professionals in government agencies, consulting firms, and academia, HCS delivers results that fully comply with the Highway Capacity Manual, making it the preferred choice for reliable traffic analysis.
A Unique Feature
Compliance to HCM
The Highway Capacity Software (HCS) faithfully implements the methods and procedures documented in the Highway Capacity Manual (HCM) without any modifications. In other words, the results from our software ensures 100% compliance to the HCM and yield the same results as those obtained through analysis solely using HCM.
Built with Rigorous Research and Review
The HCM is the most widely used reference material in transportation engineering based on multi-million dollar, high-profile, national-level research. It is overseen by the Transportation Research Board’s (TRB) Committee on Highway Capacity and Quality of Service.
HCS model’s foundation utilizes extensive traffic engineering research and a rigorous peer- review process from both a research-level and a TRB committee-level for HCM adoption. This ensures users that analyses performed using HCS to accurately reflect HCM methodologies.

Scope of Analysis
Comprehensive Analysis
HCS is a comprehensive tool capable of analyzing traffic operations, safety, and road capacity. It is able to model various scenarios, including work zones, managed lanes, and weather conditions. With HCS, you can also analyze a wide range of study periods, from a single peak hour to a full 24-hour assessment across all facility types. It also supports congested multiperiod analysis and full-year reliability studies for both freeways and arterial. Find out more below.

Analysis and Methods
Analysis of Connected and Automated Vehicles
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.
