With political polarization hindering progress in public policy and meaningful engagement at all levels of government, now is a good time to reflect on how we run public participation processes. How do legislative requirements—like those for the regional planning process in California—help or hinder meaningful public engagement? What are the biggest challenges and opportunities for improving public engagement?

Pursuing the Technological Sublime: How the Bay Bridge Became a Megaproject

Karen Trapenberg Frick

The newly opened eastern span of the San Francisco-Oakland Bay Bridge is a classic example of a megaproject at $6.4 billion and a textbook embodiment of what I have identified as the “six Cs” of a typical megaproject: colossal, captivating, costly, controversial, complex, and subject to issues of control. Here, I focus on how the “captivating” and “colossal” characteristics affected the bridge design process and implementation. Captivating and colossal projects engage and stimulate participation by a broad set of stakeholders and citizens, whose varied perspectives and inputs can be difficult to accommodate without controversy and conflict.

Dynamic Ridesharing

Elizabeth Deakin, Karen Trapenberg Frick, and Kevin Shively

Most cars can carry at least four passengers, but the average auto occupancy rate for all trips in the US is only 1.6 persons. Because all the empty seats in cars represent our greatest source of untapped transportation capacity, promoting ridesharing is of considerable interest. Government agencies across the country employ ridesharing programs both to provide transportation at low cost and to reduce traffic congestion and the other costs of solo driving.

For over 20 years, researchers at the University of California Transportation Center have asked hard questions and used the answers to help guide public policy. From its beginning, UCTC’s core research theme has focused on tying together transportation systems analysis and policy. We do this by funding research, graduate and undergraduate education, and special studies for federal, state and local governments. We also support events that bring together professionals, researchers, and students to confront key issues and identify emerging areas of interest. Our activities are made possible through generous grants from the US Department of Transportation and Caltrans.

Intelligent Transport Systems: Linking Technology and Transport Policy to Help Steer the Future

Elizabeth Deakin, Karen Trapenberg Frick, and Alexander Skabardonis

If you’ve seen an electronic message sign along the highway that tells you how long it will take to get downtown or to the airport, or paid your toll or your parking fees with an electronic tag, or ridden a bus that triggered the traffic lights to turn green as it approached them, then you have experienced some of the benefits of Intelligent Transportation Systems (ITS)—an umbrella term for a variety of new technologies and operations methods for highways and transit. Other on-the-ground ITS applications are less visible to the average traveler, but every bit as useful: they help traffic managers detect and respond to accidents promptly, handle the extra traffic that special events generate, and help state workers safely plow snow on mountain roads in blinding snowstorms.
