This application includes $1139320 of 2025 cmaq funds that thurston regional planning council (trpc) awarded to intercity transit as the lead agency for the multijurisdictional smart corridors project

The Federal Transit Administration awarded Intercity Transit $1.317 million on December 9, 2025, under the Federal Transit Formula Grants program (CFDA 20.507), with $1.139 million in 2025 Congestion Mitigation and Air Quality (CMAQ) funds passed through by the Thurston Regional Planning Council for Phase 4 of the multijurisdictional Smart Corridors Project on the Martin Way corridor in the Olympia-Lacey urbanized area.

Phase 4 expands field implementation and analysis of transit signal priority (TSP) optimization initiated in prior task orders. Intercity Transit, as lead agency, will conduct intersection-based analysis of transit performance and signal operations, evaluate signal control strategy adjustments at select intersections, develop rules for optimizing TSP timing, update TSP signal timing parameters, and identify additional corridors for Smart Corridor deployment. Work encompasses project management, stakeholder coordination, technical support, data management, and analytics. The project aims to enhance transit efficiency, reliability, and cost efficiency for Intercity Transit's operations while maximizing benefits for public users of the corridor. Performance runs through August 31, 2028, with place of performance in Washington. No subrecipients are involved; the award is a prime grant to Intercity Transit.

Activities

Phase 4 of the smart corridors project builds upon the foundation established in the first three task orders further expanding the pilot projects field implementation and analysis. This phase encompasses project management stakeholder coordination technical support data management and analytics.key activities include:- conducting an intersection-based analysis of transit performance and signal operations.- evaluating potential adjustments to signal control strategies at select intersections within the pilot corridor.- developing rules for optimizing transit signal priority (TSP) timing to enhance transit efficiency and reliability.- updating TSP signal timing parameters to improve overall corridor performance.- identifying other corridors/locations for smart corridor deployment.

Expected outcomes

The project aims to maximize transit benefits for users while optimizing internal operations to enhance reliability and cost efficiency for intercity transit. Efforts will focus on two key areas: scheduling and operational control. Specific improvements to pilot conditions will be identified and assessed leveraging actual data from earlier phases to model and evaluate potential enhancements.

Intended beneficiaries

This project is expected to improve efficiency for the general public that uses major transit corridors in the regions premier transit corridor (martin way).
