Policy Brief

This policy brief summarizes findings from a research project which examined how natural gas infrastructure can be economically and technologically synergistic for natural gas and renewable natural gas in the near term.

The researchers assessed whether the LCA framework was useful in identifying whether a complete street delivered, or was likely to deliver, the intended performance and benefits, and the social and health conditions of the neighborhoods receiving the benefits.

This policy brief summarizes findings from research to analyze the potential for zero-emission or near-zero-emission heavy-duty trucks to be used in short-haul drayage services.

This policy brief summarizes findings from research that examined the potential population division effect of highways on coyote populations in the Bay Area and Sierra Nevada foothills.

Researchers at the University of California, Davis analyzed the difference in service levels among dock-based and dockless systems in the cities of San Francisco and Los Angeles and analyzed the spatial distribution of service areas, availability of bikes and bike idle times, trip statistics, rebalancing, and other metrics to understand how well or poorly these systems serve designated “communities of concern”.

This policy brief summarizes research that tested whether or not rail transit developments cause an influx of high-income residents and an outflow of low-income residents near rail stations.

To better understand the dynamic between wildlife and vehicle traffic in Northern California, a study examined whether State Route 49 acts as a barrier to movements of two similar species with different tolerances to human activity. This policy brief summarizes findings from that study and discusses the policy implications.

A research team at the University of Southern California collaborated with Lime, an e-scooter company, to analyze Slow Streets programs in the cities of Oakland, San Francisco, Los Angeles, and Portland. Using two statistical approaches, they examined dockless e-scooter travel at four different times of day and overall weekly and monthly averages of dockless e-scooter trips. 

Researchers at UC Davis used the publicly available 2012 CHTS and 2017 NHTS California add-on data to examine the impact of methodological differences on the changes in mode shares over this five-year period and conducted a preliminary investigation into the role of demographic and other factors in these changes.

As yet, little is known about the efficacy of e-bike incentive programs in changing travel behavior. To understand the potential of these programs in this area, UC Davis researchers analyzed survey data from rebate recipients in Northern California and evaluated rebate programs for effects of e-bike ownership on travel behavior.
