 *TCAPP : A Collaborative Decision-Making Framework (C01)
A robust web-based tool that can be used as a trouble-shooting guide or a roadmap for changing a transportation agency’s process when planning and developing highway projects. TCAPP helps navigate critical decision points for long-range transportation planning, corridor planning, programming, and environmental review and permitting, when project delays can be avoided.
By ensuring that the right people are engaged at the right time with the right information, projects move ahead without delays that often arise when decisions must be deferred or revisited. TCAPP’s Decision Guide provides a framework for consistently delivering projects that address a community’s economic, mobility, and environmental goals.  
Transportation for Communities—Advancing Projects through Partnerships (TCAPP) integrates many Capacity research products. TCAPP and supporting case studies are available at the beta website www.transportationforcommunities.com.

Four pilot projects tested the functionality of TCAPP (C18A-D): the projects considered tolling, environmental conflict resolution, stakeholder agreement in project prioritization, and developing a Complete Streets plan. The final reports from these pilot tests and a synthesis of lessons learned are available on the following page.

When planning for highway capacity, successful practice requires the right people, with the right information to be at the right place at the right time. Collaboration among decision-making partners as well as stakeholders has one essential commonality: involvement is based on what matters to them. It is not necessary that the interests are common to all, but rather that the importance of individual interests are acknowledged, respected, and included in the process.  

The objective of this project was to develop a systems-based, transparent, well-defined framework for consistently reaching collaborative decisions on transportation capacity enhancements.

This project developed a flexible, adaptable collaborative decision-making framework (Framework) that provides specific information on how to support collaborative decision making within existing laws and regulations. Drawing on real-world perspectives, 23 case studies were used to provide examples of and data about successful collaborative decision making. These case studies represent a diverse group of highway planning projects ranging from a simple bridge reconstruction to a full corridor-wide planning program. From the case studies, 42 key decision points that are common to all states were identified. These decision points serve as the basis for the Framework.

The Transportation for Communities—Advancing Projects through Partnerships (TCAPP) web tool is the web-based delivery system for the Framework. TCAPP will also be the delivery system for other products from Capacity research projects—including projects C02 (A Systems-Based Performance Measurement Framework for Highway Capacity Decision Making), C06A (Integration of Conservation, Highway Planning, and Environmental Permitting Using an Outcome-Based Ecosystem Approach), C06B (Integration of Conservation, Highway Planning, and Environmental Permitting Through Development of an Outcome-Based Ecosystem-Scale Approach and Corresponding Credit System), and C09 (Incorporating Greenhouse Gas Emissions Into the Collaborative Decision-Making Process).

Project Status: This project is completed.

Product Availability: The case studies are available on the following page. The final report is available as a prepublication document. TCAPP is available at www.transportationforcommunities.com. The final reports from these pilot tests and a synthesis of lessons learned are available on the following page.
