Infrastructure Provision

The NCST develops and assesses strategies that reduce GHG emissions as well as criteria pollutants, water and soil pollution, and other environmental impacts associated with infrastructure provision and systems operation, with attention to the implications for disadvantaged communities. NCST studies have explored better lifecycle use of materials and improved practices in roadway construction, maintenance, and operation. Other studies examine innovative Intelligent Transportation System (ITS) as well as connected and automated vehicle (CAV) strategies that reduce greenhouse gas emissions while producing safety and mobility benefits.

Comparing REAP and AHSC: State-defined versus regionally-defined funding strategies for affordable housing linked to multi-modal transport

Principal Investigator Elisa Barbour, Ph.D.
University of California, Davis

This research project will compare key elements of program design, administration, and projected benefits from the Regional Early Action Planning (REAP) and Affordable Housing and Sustainable Communities (AHSC) programs, with the aim of considering how and whether a state-led strategy (AHSC) differs from regionally-designed strategies (through REAP), in furthering SB 375 goals through funding that allocated for similar specific purposes.
