TO SUPPORT DECISION-MAKING

Transportation and Warehousing contributes $1,747 billion to the US gross domestic product. Source: Bureau of Transportation, 2022. 5 to 1 economic return produced by long-term investment in public transit. Source: APTA, 2023. $1 billion in Federal-aid highway investment supports 19,700 full-time equivalent jobs in supplying sectors such as construction and 14,500 jobs in the general economy.

WHY INTEGRATE ECONOMIC ANALYSIS INTO DECISION-MAKING?

This ensures that infrastructure investments align with broader economic development goals. By coordinating transportation planning with anticipated economic activities, resources can be allocated more efficiently, leading to improved connectivity, reduced costs, and enhanced access to markets and labor. This approach also helps in forecasting future demands, preventing bottlenecks, and supporting sustainable growth, ultimately leading to a more resilient and competitive economy.

SNAPSHOTS OF PLANNING PRACTICES:
ECONOMIC ANALYSIS | KEY PRACTICES

Different organizations might optimize their approach towards economic analysis by focusing on one or more “levers of change” within their organization. These levers of change – Organization, Workforce, and Partnerships; Data and Performance Management; and Policy and Program Design – are the organizing framework of these key practices. This structure is intended to offer practices in each area so that organizations can choose where to focus their energy and resources. The practices are divided into three categories: 1) “Designing” describes practices, examples, and resources relevant to agencies who are new to the topic area or setting up a new program, 2) “Enhancing” describes practices among agencies that are expanding or growing their efforts in a area and taking on increasingly complex aspects of the topic., and 3) “Advancing” describes practices, examples, and resources relevant to agencies that are innovating or establishing new practices in a topic area.

DESIGNING

Exemplary practices for agencies who are new to using Programmatic Economic Measures for Evaluation & Prioritization.
ORGANIZATION, WORKFORCE, AND PARTNERSHIPS:

Establishing relationships within the organization, with other agencies, and with other planning organizations with responsibilities related to economic development (e.g., economic development, workforce, or business development organizations).

DATA AND PERFORMANCE MANAGEMENT:

Conducting an inventory of available macroeconomic and other data required for economic analysis. Start to collect and consolidate relevant data and identify gaps.

Building tools such as matrices that allow high-level project scoring or screening based on economic analysis factors..

POLICY AND PROGRAM DESIGN:

Assessing pre-project phases, such as needs assessments and planning studies, where economic analysis could be integrated.

Assessing project planning, scoping, and screening processes and identifying the phase (prior to prioritization) where economic analysis could be integrated.

ENHANCING

Exemplary practices for agencies who are expanding or growing their use of Programmatic Economic Measures for Evaluation & Prioritization.
ORGANIZATION, WORKFORCE, AND PARTNERSHIPS:

Utilizing relationships established in the “Designing” phase to encourage metropolitan planning organizations (MPO), regional transportation planning organizations (RTPO), and local governments to collect and share their own economic performance measure data.

Maintaining the relationships with economic development and workforce organizations established in the “Designing” phase, determining stakeholders’ data needs, and evaluating opportunities to expand partnerships. This could include establishing a working group or advisory committee for regular communication.

DATA AND PERFORMANCE MANAGEMENT:

Working collaboratively with partner agencies and stakeholders to determine ongoing responsibilities related to collection and maintenance of transportation data relevant to economic analysis. Integrating the understanding of these roles into organizational policies.

Building tools such as matrices that screen projects or provide high-level scoring along economic analysis factors. Considering how this tool might later be used to prioritize projects.

Translating relevant data into a GIS layer which can be layered with other geographic data to help understand how economic development, workforce development, and transportation data interact. Developing guidance on how to integrate this information into planning and project scoping processes.

POLICY AND PROGRAM DESIGN:

Working collaboratively to incorporate economic analysis into both short- and long-term planning processes. This could include topics such as identification of major economic centers, workforce trends, forecasts for passenger and freight demand and economic growth opportunities.

Establishing economic factors into project prioritization process.

ADVANCING

Exemplary practices for agencies who innovating & establishing new best practices in their use of Programmatic Economic Measures for Evaluation & Prioritization.
ORGANIZATION, WORKFORCE, AND PARTNERSHIPS:

Hiring staff as needed to conduct and lead economic impact analyses.

Providing sufficient funding to continue economic impact analyses and institutionalize this process.

Fostering partnerships for economic data collection and management through regular stakeholder meetings.

DATA AND PERFORMANCE MANAGEMENT:

Institutionalizing economic performance measure analysis as an integral component of major transportation projects, including standardized and automated processes for data collection, management, and sharing.

Developing the ability to produce in-house data and performance-based reports and share models for replication by stakeholders.

POLICY AND PROGRAM DESIGN:

Identifying and addressing any emerging challenges around geographic equity in economic analysis (e.g., by limiting competition for funding to regional pools, comparing projects in similar urban contexts, or adjusting criteria or weighting).

GAPS AND FUTURE RESEARCH

How can agencies obtain more granular economic data useful for project-level analysis? Who is gathering this type of information and how can agencies obtain and use it for their work?

What are some quick-response tools that allow for high level understanding of a project’s economic benefit, without needing to complete a large, complex calculation?

ECONOMIC ANALYSIS | EXAMPLES

This Snapshot focuses on best practices in calculating the economic impact of transportation projects in order to evaluate and prioritize transportation projects and investments. This economic analysis can be used to inform the decision-making process, guiding agencies toward funding projects that will best meet agency, state, and federal goals.

DESIGNING

Some agencies are partnering with stakeholders and integrating external economic analyses or plans to support their transportation economic analyses. This allows the agency to gather targeted information on industries and aspects of their community that are important for jurisdiction level growth.
