This session presents a framework that provides access to public agency databases to ensure HCM-compliant freeway system analysis. A digital twin of the freeway network includes segmentation and demand data, which can be imported directly for a selected facility stretch and study period for analysis based on the Highway Capacity Manual (HCM).

A case for the North Caroline state is presented. Depending on the data available for a state, the online segmentation database enables to set up of the model in a matter of minutes and allows software end users to perform any single-day and whole-year freeways such as work zone or reliability analyses.

A tool for segmenting freeway facilities on an online maps background is also presented to complement online databases. The analyst only needs to pinpoint on and off-ramp points on the freeway to build a facility with resulting merge/diverge, weavings and basic segments according to the HCM segmentation rules for freeway analysis.

As a result, this presentation shows how to leverage digital twins models for freeways to overcome challenges for a wider implementation of the HCM methods, facilitating engineers to access the methodologies and adequate databases, which allows for conducting accurate and efficient planning and operations studies for freeways.
