100 Lecture Series: Making Change Happen with Jody Litvak
Even with a great idea, and excellent planning and design, change is often painfully, frustratingly slow. In this talk, Jody Litvak draws from her 40-year career in government and community relations to explore the critical bridge between idea and reality. Moving a project, program or initiative from concept to a finished product requires more than technical expertise; it demands a deep understanding of tactical implementation, public-sector lobbying, coalition-building, the complex web of community interests and decision-making. Using real-world case studies, including the political navigation of major infrastructure projects in Los Angeles, Jody will break down the strategies necessary to manage this “messy” but necessary process.

100 Lecture Series: Overbuilt: The High Costs and Low Rewards of U.S. Highway Construction with Erick Guerra
Since the 1956 inception of the Highway Trust Fund, the U.S. has spent approximately $2.5 trillion (inflation-adjusted) on highways, with 60% of that investment occurring after the Interstate System was largely completed in 1992. Despite shifting public priorities toward safety and equity, planners have since added 75% more urban interstate lane miles.
In this lecture, Erick Guerra reflects on his book Overbuilt and argues that the costs of this continued expansion outweigh the benefits. He traces the historical context of our roadway obsession and examines the economic and social consequences of overbuilding. By analyzing the mechanics of the gas tax and transportation finance, Guerra reveals why the U.S. remains committed to increasing roadway capacity. Importantly, the book provides a roadmap for reform, showing how new evaluation measures can help policymakers stop and correct decades of overbuilding.

InterActions LA 2026
California has set ambitious goals to address its housing crisis, improve transportation, reduce greenhouse gas emissions, and improve quality of life. But making meaningful progress on these goals is stymied by its most formidable challenge — local and regional implementation.
Agencies and governments must adopt new approaches and solutions, and work in new ways to implement them, often departing from the status quo or existing internal structures. While academic evidence can offer promising insights into what should be done, it says less about how cities actually enact them. This conference bridges that gap.

100 Lecture Series: The Long Life of Urban Form: How the Past May Define the Future of L.A. Transit with Genevieve Giuliano
In an era of rapid technological change — from e-bikes to autonomous vehicles to delivery bots — as well as major policy efforts to transform Los Angeles to a transit metropolis, it is easy to think that the city of tomorrow will be something very different from the city of today. However, Genevieve Giuliano finds that four decades of data tell a different story: one of remarkable stability in the structure of the region and its travel patterns.
In this lecture, Professor Giuliano considers L.A.’s transit future. As Los Angeles navigates the “hallowed ground” of personal mobility and the evolving role of its historical centers, we face a critical crossroads. If downtowns are shifting from employment hubs to residential anchors, and face-to-face interaction remains the bedrock of the economy, what is the future for transit — radical experimentation or doubling down on high-capacity infrastructure?

100 Lecture Series: Reparative Development: Destination Crenshaw as a Model for Community-Led Infrastructure with Jason Foster
For decades, major transit projects in Los Angeles have often bypassed or displaced Black communities. Jason Foster, president and CEO of Destination Crenshaw, argues that the future of L.A. transportation must shift from mere movement to “Reparative Development.”
Using the 1.3-mile Destination Crenshaw corridor as a live model, Foster explores how the city can leverage transit infrastructure to anchor legacy businesses, grow the urban canopy, and create cultural permanence. By centering local empowerment over federal-down mandates, this uniquely “L.A.” approach proves that transportation can be a vehicle for economic justice rather than a driver of displacement. Join the UCLA Institute of Transportation Studies to discuss how this South L.A. renaissance provides a scalable roadmap for community-led infrastructure across the region.
