Evaluation Approach

Grantees are required to track data on the impact of funded projects during project implementation in the following areas:

• Vehicle telematics data: Grantees collect quantifiable data on project operations, such as number of users, number of trips, VMT per user and per trip, average utilization rate, and average fare cost, via vehicle telematics. 
• User surveys: Grantees deploy multiple user surveys over the course of project implementation to collect data that cannot be collected via telematics. This includes, but is not limited to, data such as the demographics of users, user experience, trip purpose, alternative transportation mode if the project service had not been available, pre-project travel behavior, pre-project transportation challenges, changes in travel behavior post-project, changes in transportation access post-project, and changes in perception of zero emission vehicles and equipment post-project.
• Community engagement and outreach: Grantees track data on outreach and engagement activities, including quantitative data, such as the number of events/activities and participants reached, and qualitative data on the nature and impact of the events/activities.
• Lessons learned: Grantees also share lessons learned during project implementation that help CARB track and respond to overarching challenges and best practices.

CARB also has three current or recently concluded research contracts intended to evaluate implementation of a portion of CARB’s clean mobility and planning investments:

• Clean mobility project evaluations: CARB has a contract with UC Berkeley’s Transportation and Sustainability Research Center that includes evaluation of three STEP Implementation Grants. Researchers are using these STEP grants and other CARB-funded clean mobility projects to assess the effectiveness, sustainability, and outcomes of funded shared mobility projects.
• Community-based transportation planning evaluations: In January 2024, UC Berkeley’s Othering and Belonging Institute published an evaluation of both STEP Planning and Capacity Building Grants and Clean Mobility Options Community Transportation Needs Assessments. The report, titled Advancing Equitable Community-Based Transportation Planning, includes recommendations to address programmatic issues, equity concerns, and questions raised throughout the project research activities to support improved institutional and community capacities for equitable transportation.
• Place-based equity evaluation framework: In 2024, CARB entered into a contract with UC Irvine titled “Activity- and Accessibility-Based Framework for Mobility Equity Evaluation”, which includes evaluation of several current STEP Grant case studies. Researchers are developing an evaluation framework to assess the synergistic equity impacts of place-based, community-scale mobility investments.

Socioeconomic Benefits

CARB is continuing to collect data on and develop a process for understanding the socioeconomic benefits to clean mobility users from clean mobility projects. This will incorporate the value of reliable, clean transportation and the cost savings of funded clean mobility services relative to other options. The analysis will continue to be updated and estimates refined based on stakeholder feedback obtained through a public workgroup process and additional grantee surveys and vehicle telematics data. In the meantime, the table below describes some key socioeconomic benefits, metrics, and reportable outcomes for STEP.
