Highway Capacity Manual HCM

Reliability in Compliance

We are dedicated to faithfully implementing the methodologies of the HCM. For over three decades, users have relied on HCS to make their analyses comply with HCM. This trust has been built over 35 years of frequent updates and developments to the HCS as new updates to the HCM become available. These range from major releases to the HCM to minor updates (e.g., errata) approved and adopted by the TRB Committee on Highway Capacity and Quality of Service (ACP40).

Expert-led Training

The staff at McTrans is made up of experts with years of experience in the industry. We are pleased to offer multiple training opportunities, including a variety of courses for transportation professionals.

Highway Capacity Software (HCS)

Join over 15,000 users worldwide who use HCS for surface streets traffic analyses.

The Highway Capacity Software (HCS) is a comprehensive tool to analyze roads, including freeways, arterials, and intersections. It uses the US Highway Capacity Manual’s (HCM) methods as its basis. The first version of HCS was released in 1987 (36 years ago!), and since then, a vast number of releases have been made to make sure all HCS users are using the latest methodologies in the HCM.

TSIS-CORSIM

A robust and transparent traffic simulation tool.

TSIS-CORSIM is a microscopic simulation tool capable of defining and managing traffic analysis projects, defining traffic networks and creating inputs for traffic simulation analyses, executing traffic simulation models, and interpreting the results of those models.

Volume 4 of the FHWA’s Traffic Analysis Toolbox (CORSIM Application Guidelines) is available on the Federal Highway Administration (FHWA) traffic analysis tools home page.

Highway Safety Software (HSS)

Use a single platform to perform traffic safety and capacity analyses!

The Highway Safety Software (HSS) faithfully implements the Predictive Method of AASHTO’s 1st Edition Highway Safety Manual (HSM) and its supplement HSM 2014, allowing for local and state-level calibration for parameters. The base model to predict crash frequency was built to consider the local infrastructure and operational characteristics.
