Federal funding programs, organizational barriers, and other factors mean that performance management techniques are often applied within silos. Furthermore, although several transportation organizations have begun to develop more comprehensive performance measures that better reflect their diverse planning goals and objectives, measuring performance for the transportation network and using measures across various stages of the transportation planning process remains a challenging endeavor.

Similar to challenges associated with multimodal measures, comparing the benefits of smaller-scale investments, such as system operations projects, to larger roadway projects is hindered by limitations of commonly used technical tools, which have been developed over decades to assess the impacts of added roadway capacity. The same can be said for other types of smaller-scale investment strategies intended to improve traffic flow and transportation efficiencies (e.g., travel demand management measures)

Network performance measures • Address the regional, state, or multistate impacts of individual decisions; • Are derived from a process that involves multiple actors working in collaboration; • May span multiple jurisdictions, modes, investment strategies, and stages of the plan and project development process; • Are connected with broader outcomes and systemwide performance objectives; • Measure the performance of a transportation network, not only individual facilities; and • Are supported by data and tools that provide a fair comparison of different types of investment strategies. Define Network Performance Strategies One of the key dimensions of network performance is the consideration of multiple types of strategies.

Capital District Transportation Commission planning process 4 Regional Scenario – Multimodal and Multistrategy Investment Prioritization Decreasing resources and an interest in funding projects with the most favorable benefit–cost ratio has increased the interest in analyzing all projects across a system for planning and programming purposes. These efforts typically include many entities with varying responsibilities for the transportation network.

The scenarios describe specific applications of network performance, but a common set of building blocks also has been identified. These building blocks include the following: – Establish Partnership Agreements.
