Policy Brief

This policy brief summarizes the findings from and policy implications of work to understand potential users’ perceptions of safety and security risks posed by intertwined social and technical systems of e-SAVs and proposed a framework to advance research, policy, and system design.

This policy brief summarizes findings from two projects that simulated traffic patterns along a section of Interstate 710 near the Ports of Long Beach/Los Angeles, and the use of variable speed limit and lane change control systems to evaluate the potential traffic impacts of these systems.

Senate Bill (SB) 743 (2013) and its related regulations eliminated automobile level of service (LOS) and replaced it with vehicle miles traveled (VMT) as the primary transportation impact metric for land development projects. The LOS-to-VMT shift was expected to create many challenges for transportation analysts. With those concerns in mind, researchers at the University of California, Davis investigated how local governments have been implementing the LOS-to-VMT shift.

This policy brief discusses factors related to retention and knowledge management in the Vermont Agency of Transportation (VTrans).

This policy brief summarizes findings from the white paper that assesses academic research and transportation planning practice to provide a shared understanding of the definitions, challenges, and opportunities in the field of transportation equity.

A research team at the University of California, Davis examined the track record of the past decade for clues as to why cellulosic fuels that can have a significantly lower carbon footprint per unit energy failed to materialize at commercial scale, and looked forward to 2030 to point to how current policies are likely to still fall short in delivering low-carbon biofuels that can reach scales needed for these hard-to-decarbonize sectors.

Researchers at the University of California, Davis partnered with Cal-ITP to study how transit fare payments could be modernized while remaining accessible to unbanked and underbanked riders.

Policies developed to support drivers of used PEVs may ultimately attract a broader group of people into the PEV market, as used vehicles are less expensive than new ones. Researchers at the University of California, Davis used aggregated data at the zip code level to understand where buyers of second-hand PEVs are located, and to explore differences in the location and characteristics of regions with more original owners vs. second owners of PEVs.

University of Vermont researchers analyzed national survey data on transportation burdens to evaluate the differences in who experiences transportation burdens in rural versus nonrural areas, the factors that drive these differences, and how to improve mobility and access in rural populations.

This policy brief summarizes findings from research that surveyed California PEV buyers 2–7 years after they first purchased their EV to understand whether they have continued to choose PEVs with subsequent purchases, and if not, what factors may have led to their discontinuance of the technology.
