Caltrans’ CSIS metrics to shape TIRCP scoring; staff will score CAPTI alignment

Henry McKay, acting data science branch chief at Caltrans, explained that CSIS (the Caltrans System Investment Strategy) will be used in the TIRCP cycle as a secondary prioritization framework tied to CAPTI (Climate Action Plan for Transportation Infrastructure).

McKay said CSIS has three components: program fit (existing TIRCP eligibility), CAPTI alignment metrics (the primary way CSIS will affect awards), and other considerations such as delivery risk and leveraged matching funds. "There are 11 CAPTI alignment metrics, nine of which are quantitative and two qualitative," he said.

Metrics and scoring: McKay listed metrics including safety (grade crossings and VMT-related safety impacts); vehicle miles traveled (VMT) reductions; access to destinations (with special attention to disadvantaged communities); passenger mode shift; land-use support for high-quality transit areas; freight sustainability and efficiency; and ZEV infrastructure. The two qualitative metrics are public engagement and climate adaptation/resiliency, scored using rubrics and documentation review.

Data inputs and process: McKay said applicants will supply input data, but Caltrans staff will calculate metric scores via a structured intake form and review process. "Applicants aren't expected to actually calculate these metrics and submit them to us," he said; staff will score metrics based on applicant-provided inputs and linked documentation.

Implications for applicants: Not all projects will affect every metric—some projects (for example, local bus work) may not move the needle on freight—so applicants should focus data collection on applicable metrics. Caltrans will release a memo and documentation explaining how TSYS (CSIS) considers transit and rail benefits for each metric.

Next steps: Staff said they will provide more detailed guidance and release a memo with the call for projects explaining metric application to rail and transit projects.
