Community of Practice

Welcome to the Community of Practice (COP)! This is an integrated online Community of Practice for the Travel Model Improvement Portal (TMIP) and the Freight Model Improvement Portal (FMIP). The objective of this COP is to provide an effective platform to encourage and facilitate information sharing, the exchange of ideas, and capacity building within the travel and freight modeling and planning communities. The online Community of Practice does not represent the official policy or position of FHWA and does not constitute an endorsement, recommendation or specification by FHWA. 

Explore the publicly available webinars and resource library or register for an account to join in the exchange of ideas on the discussion forum.

Note: we are committed to providing equal access to information for everyone. If you need alternative formats or other reasonable accommodations, please send an e-mail to with your request. We will respond to your request within 24 hours.

What's New

  • Promises of Data from Emerging Technologies for Transportation Applications: Alaskan Way Viaduct Replacement Project

    The closure and demolition of the Alaskan Way Viaduct and the opening and tolling of the new SR-99 Tunnel represent major infrastructure changes (i.e. major events) in downtown Seattle. This project applies big data (i.e. app-based data) and traditional flow data (e.g., traffic volumes and travel times) to study the mobility pattern changes due to these major events. Analyses of system performances (delay and volume changes) and travel patterns are conducted at the regional, neighborhood, and facility user levels. Findings obtained from this study, i.e., changes in travel patterns from before to after the Alaskan Way Viaduct replacement and tolling project, demonstrate the validity of using big data for before and after transportation impact assessment. The report is now available at 

  • Introducing TMIP Transportation Modeling and Analysis Toolbox...

    TRB Special Report 288 finds that "... there is no single approach to travel forecasting or set of procedures that is "correct" for all applications or all MPOs. Travel forecasting tools developed and used by an MPO should be appropriate for the nature of the questions being posed by its constituent jurisdictions and the types of analysis being conducted." (METROPOLITAN TRAVEL FORECASTING: Current Practice and Future Direction, Transportation Research Board, 2007, Page 3)

    The objective of the TMIP Transportation Modeling and Analysis Toolbox (the Toolbox) is to provide access to a range of tools developed by TMIP to support data driven, performance-based transportation planning incorporating principles of risk management. The goal of the Toolbox is not to create a single - or even a set of - ideal tools, but rather to provide processes, information, and examples to encourage agencies to select the appropriate tools and methods based on their analytical needs.

    The toolbox is available at
