1998

This report is a summary of proceedings from a two-day symposium convened by the Institute of Transportation Studies at the University of California at Berkeley in April 1998 to commemorate the fiftieth birthday of the Institute and to lay the groundwork for the Institute’s second fifty years. With the title, The Transportation Enterprise: Challenges of the 21st Century, the Symposium set out to generate thoughtful, active discussion in preparation for laying out an action plan for the Institute in the21stCentury.

Wildfire Evacuation Planning Can Be Greatly Enhanced by Considering Fire Progression, Communication Systems, and Other Dynamic Factors

Wildfires have become a perpetual crisis for communities across California. For life-threatening wildfires, mass evacuation often becomes the only viable option to protect lives. Yet, looking back at recent events, including the devastating 2018 Camp Fire in Northern California, there are significant challenges associated with the evacuation process, such as multi-agency coordination, agency-resident communication, and management of extraordinarily high amounts of traffic within a short period of time. Currently, emergency planners use evacuation models that are typically based on existing...

Are our Transit Systems Ready for Earthquakes?

Located on the tectonic boundary with multiple active faults, the San Francisco Bay Area is highly vulnerable to earthquakes. The United States Geological Survey (USGS) has estimated a 72% probability of an earthquakewith a magnitude of 6.7 or greater striking the region within the next 30 years. Historical seismic events have demonstrated the profound impact earthquakes can have on transportation systems. During the 1989 Loma Prieta Earthquake, the closure of the San Francisco-Oakland Bay Bridge, a critical transit route for San Francisco commuters, left nearly 400,000 commuters and...

Connected and Automated Vehicle Technology is Not Enough; it Must also be Collaborative

Patire, Anthony D., PhD
Dion, Francois, PhD
Bayen, Alexandre M., PhD
2023

Connected and automated vehicles (CAVs) willrevolutionize the way we travel; however, what impact this revolution will have on advancing broader societal goals is uncertain. To date, the private sector technology rollout has emphasized the automation side of CAVs and neglected the potentially transformative possibilities brought by a more collaborative notion of connectivity. This may have significant downsides from a broader societal perspective. For example, CAVs (including those on the road today) collect a vast amount of data gathered through onboard systems (e.g., radar, lidar, camera...

Policy Brief: Social Equity Impacts of Congestion Management Strategies

Shaheen, Susan, PhD
Stocker, Adam
Meza, Ruth
2019

To better understand the equity implications of a variety of congestion management strategies, researchers at the Transportation Sustainability Research Center (TSRC) at University of California, Berkeley analyzed existing literature on congestion management strategies and findings from 12 expert interviews. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework1 to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular strategy. The congestion management strategies of...

Local Government Strategies to Improve Shared Micromobility Infrastructure

Shaheen, Susan, PhD
Martin, Elliot, PhD
Cohen, Adam
2024

Shared micromobility (bikesharing and scooter sharing) experienced market growth since 2021, rebounding from the pandemic across markets in the US, Mexico, and Canada. In partnership with the North American Bikeshare and Scootershare Association (NABSA) and Toole Design, researchers at the Transportation Sustainability Research Center (TSRC) at UC Berkeley have collaborated on the data collection and analysis of the shared micromobility industry metrics through a series of annual reports beginning in 2019. This includes a series of operator and agency surveys.1 Most recently, TSRC...

Local Governments Strategies to Improve Shared Micromobility Infrastructure

Shaheen, Susan, PhD
Martin, Elliot, PhD
Cohen, Adam
2024

This brief explores how shared micromobility (bikesharing and scooter sharing) has evolved since the pandemic. Primary data for this report were collected through four surveys: An Operator Survey (n=25) and an Agency Survey (n=52) distributed between January 2022 and May 2022 to all known shared micromobility operators and agencies and included questions about the attributes of shared micromobility systems1 operating within those agency jurisdictions and operator markets; and a similar Operator Survey (n=29) and an Agency Survey (n=52) distributed between January 2023 and June 2023 to all...

Where are Private “Smart City” Transportation Technologies Concentrated in California?

In recent years, “smart city” information and communication technologies have proliferated. For local government agencies, procuring and introducing these technologies offers the possibility to manage infrastructure assets more effectively, plan for preventive maintenance, and disseminate schedules and information about transit and other services. Many of these technologies are deployed by private firms in the context of local regulations and government-sponsored incentives. In the transportation sector, examples of “smart city” technology services provided by private firms include:...

Creating a Regional Program for Preserving Industrial Land: Perspectives from San Francisco Bay Area Cities

Roach, Emily
Chapple, Karen, PhD
2018

Industrial land plays a vital role in supporting the regional economy in the San Francisco Bay Area. It provides the operating space and support services for export sectors and other important local clusters, maintains linkages between businesses and sustains a local supply chain, provides diverse employment opportunities for people with a broad range of skills (including those with lower educational attainment), and supports a high share of middle-wage job opportunities. However, the Bay Area’s current inventory of industrial land (and associated jobs) is at risk due to increasing...

UC Berkeley Develops New User-Friendly Tool to Expedite the Evaluation of Connected Automated Vehicle Technologies

Fu, Zhe
Liu, Hao, PhD
Lu, Xiao-Yun, PhD
2020

Connected Automated Vehicles (CAVs) are similar to other automated vehicles with the distinguishing difference being that CAVs obtain information about road conditionsdirectly from other vehicles and infrastructure (e.g., traffic signals, road sensors) rather than relying solely on onboard sensors. Different CAV technologies are currently being tested and evaluated to assess the prospects for future implementation. These tests involve moving CAV-equipped vehicles on a physical test track and recording how the vehicles operate under different traffic conditions (Figure 1). Since it is...
