27 C H A P T E R 3 3.1 Summary of Testing Opportunities In order to develop an implementable framework that advances the state of the practice for performance-based cross-asset resource allocation, the tool prototype was developed and tested across multiple audiences at workshops across the country. Feedback gathered from participants has assisted the research team in understanding the ways the framework and tool prototype could be used by practitioners (detailed in Section 3.3)

Testing the Tool Prototype 29 Illinois Tool Tesng Springfield, Illinois August 26, 2014 A broad range of department leaders and specialists parcipated in the workshop, including directors, secon chiefs, program development managers, bureau chiefs, unit chiefs, squad leaders, and planning analysts. Disciplines represented included bridges, cost esmang, land acquision, locaon studies, operaons, pavement management, planning, performance and cost support, and programming.

Testing the Tool Prototype 31 • Analyzing investment trade-offs: Participants suggested that this tool is not so much a "crossasset" tool as a "cross-investment" tool. The tool could be expanded to look across modes and has the ability to consider performance with regard to operations (e.g., congestion)

32 Guide to Cross-Asset Resource Allocation and the Impact on Transportation System Performance In anticipation of implementing the framework with long-range transportation plans, several participants asked how the tool prototype could be adapted to predict performance over time. While this was outside the scope of the project, the tool can be analyzed from the top down or repeatedly run on a year-by-year basis with manual updating based on what projects were selected each year.
