transportation system performance; ADOT

SB 1086 establishes performance standards for Arizona's transportation planning, requiring the Arizona Department of Transportation (ADOT) to prioritize specific metrics when selecting projects and allocating funds. For highway projects, it mandates weighting congestion reduction (40%) and mobility (40%) most heavily, with safety improvements (20%) as a secondary factor; for transit projects, it sets minimum ridership thresholds (70% of system average, or 50% for privately operated lines). The bill prohibits considering vehicle travel mile reduction targets and requires non-discriminatory application of these standards. It was passed by the legislature in April 2025 but vetoed by the Governor on May 2, 2025, preventing it from becoming law.
