CALLING VOLUNTEERS

Now we need your help to 

take the Data Hub to the next 

level. We would like you to 

test drive the software and 

provide us your feedback on 

how to make it more useful, 

seamless, and applicable to 

your day-to-day modeling 

work. 

According to Federal Highway 

Administration’s The Effective 

Integration of Analysis, 

Modeling, and Simulation 

Tools (FHWA-HRT-13-036), 

the Data Hub is estimated to 

reduce model development 

and analysis efforts by up to 

80 percent. 

The “Data Hub” was 

created to simplify complex 

transportation analyses requiring more than 

a single resolution (macro, meso, micro, deterministic), 

for applications such as Integrated Corridor Management 

(ICM), roadway pricing/tolling, and air quality analysis. 

The Data Hub uses a data schema to manage the interchange 

of data from common off-the-shelf software programs. The 

graphical user interface displays measures of effectiveness 

from field and model data in a side-by-side format which 

enables more effective calibration and validation processes.

A prototype Data Hub was successfully tested on subarea 

networks in Portland, OR; Tucson, AZ; and Raleigh, NC. 

Additional applications are currently being undertaken by 

the research team to demonstrate its benefits.

This diagram summarizes the relationship comprising the 

analysis, modeling, and simulation (AMS) data hub.

This complex system diagram depicts a series of 

connections with a close-up view of two main elements 

showcasing the analysis, modeling, and simulation (AMS) 

data hub architecture.
