MAP-21 Reporting: CATT Lab is here to help!


Apart from being the premier traffic data analytics lab in the country, the CATT Lab has special qualifications to help you comply with the recently-enacted MAP-21 highway performance monitoring rules. First, we actually wrote the book on how to analyze the type of data sources that are specified in the mandates. The tools and visualizations we created – the original Vehicle Probe Project (VPP), or today’s Probe Data Analytics (PDA) and NPMRDS Analytics suites – have paved the path for the design of modern performance monitoring programs. Second, our RITIS Massive Data Downloader is now the official portal for all downloads of the NPMRDS, which is the federally-funded dataset that most agencies are likely to use for their MAP-21 compliance calculations (the suites named above already work seamlessly with the NPMRDS). And thirdly, throughout the MAP-21 rule-making process the CATT Lab helped dozens of agencies evaluate and comment on the performance measures that were proposed, by providing easy-to-use tools and dashboards to understand the implications of each proposed requirement for each agency’s local area.

We have now re-tooled these resources to align with the final rule, and to deliver the benefits of 2017’s improved-quality NPMRDS. We are also working with our partners, including other universities and AASHTO, to suggest strategies and list step-by-step procedures to test and select the most appropriate targets for each metric. And finally, we are designing templates for simplified preparation of all of the documents required by FHWA for submission.

So you may sit back and relax now, we've (still) got this!

If you are not already receiving MAP-21 updates from us, please provide your contact information and we will get in touch with you (info@cattlab.umd.edu). Or if you like, feel free to reach out directly to Lab Director Michael Pack (packml@umd.edu).

MAP-21 Performance Calculation Tools

The CATT Lab has developed tools that are available to states, MPOs, and consultants working on behalf of an agency to better explore the National Performance Management Research Data Set (NPMRDS). Within this suite of tools is a MAP-21 widget that allows you to quickly and easily calculate your region's performance as described in the Final Ruling subparts E and F (subpart G is currently in development).

The tool outputs the systems performance measures as charts, maps, and data files that can be used to report up to FHWA or to simply understand your agency’s performance.

The tool can be found at npmrds.ritis.org.

Detailed tutorials will be added soon, so please check back often.

How do I get access to NPMRDS Analytics?

If you already have a RITIS account, your existing login is all you need. If you do not have a RITIS account, you may register for a new account. Most accounts will be approved and ready for use within one business day.

Any users experiencing issues with access or login should email support@ritis.org.

Providing Your Data to Us

For most of the required performance metrics in the final rule, all of the data needed for calculation are available through FHWA; however, for subpart G agencies must provide their own posted speed limit data. In addition, the ruling gives agencies the option to use their own data sets instead of the FHWA-provided sets if they prefer.

The CATT Lab is willing and able to help configure NPMRDS Analytics with your agency's data. We are currently able to incorporate posted speed limits and AADT/volume data as long as they are provided in the formats described below. To discuss the specifics of any data set you would like to provide the CATT Lab, please contact us at intake@ritis.org.

Posted Speed Limit Data Format

Posted speed limits for your region should be provided in miles per hour (mph) for each individual TMC segment.

Speed Limit Sample Data
TMC Posted Speed Limit (mph)
108+05158 70
108P05158 70
108+05159 70
108P05159 70
108-04817 45
108N04817 45

Volume Data Format

Volume should be provided per TMC, and can be provided as AADT or broken down into time bins (preferred). The following definitions are used below:

Volume is provided for each individual TMC link as either AADT or broken down into time bins. We expect to receive data that is unidirectional per TMC (please contact us if you have only bidirectional data).
