The potential for automated vehicles (AVs) to reduce parking in central cities has generated much excitement among urban planners. However, a reduction in parking could be accompanied by increased demand for curbside DO/PU space with related movements to enter and exit the flow of traffic.This study uses a microscopic road traffic model with local travel activity data to simulate personal AV parking scenarios in San Francisco’s downtown central business district (CBD).

Researchers at the University of California, Davis modeled the travel effects of changes in drop-off and pick-up activity and parking supply that might be triggered by widespread automated vehicle use in San Francisco’s city center. This policy brief summarizes the findings from that research and provides policy implications.

This policy brief discusses the role of life cycle assessment in reducing greenhouse gas emissions from construction in maintenance with a focus on pavement.

This policy brief summarizes findings and policy implications from UC Davis research that developed models for e-commerce demand, last-mile delivery operations, and cost and sustainability assessment, then applied this modeling framework to a case study in Southern California to evaluate the potential impact of these strategies under different delivery scenarios

This project developed a microscopic traffic simulation network and evaluated the impact of combined variable speed limit and lane change control on the environment when truck volume is high.

Researchers used time lapse cameras to track shoreline changes due to sea level rise and discussed how outputs from their techniques could be used to inform transportation and regulatory decision-making

While it is not realistic in the foreseeable future for most Californians to live without their cars, it is possible to decrease car dependence. Creating a less car-dependent world is not necessarily more costly to the public and can be achieved over time through changes in land use and transportation planning practices. Answers to many of the frequently asked questions about such efforts are provided.
