A month after releasing a well-received guidebook on pop-up bus-only lanes, the UCLA Institute of Transportation Studies issued an addendum with solutions to one of the biggest obstacles — lack of enforcement. Best Practices in Implementing Tactical Transit Lanes highlights the recent surge of bus-only lanes that are “tactically implemented in dense, congested areas to speed up transit.” Tactical transit lanes, or TTLs as they’re affectionately called, are inexpensive and quick to implement, but they break down without enforcement. “We heard concerns from planners across the country about how to effectively enforce TTLs so we went back to our partner transit agencies to reconsider what ‘tactical’ could really look like,” said Juan Matute, ITS deputy director and co-author of the report. TTL 2.0 solves this problem completely. Using a combination of low-cost accessories, such as plows, drill heads, continuous tracks used on tanks, and monster truck wheels, transit operators can now tactically avoid or relocate improperly parked vehicles and other offending items. The figures below demonstrate how these simple interventions can be utilized. Figure 1: A continuous tread to break through enemy parked obstacles.

Across the country, public transit ridership has been declining. But that isn’t the story in Seattle and Terry White, deputy general manager at King County Metro Transit, said that could be attributed to the agency’s community efforts. Speaking at the UCLA Institute of Transportation Studies’ 12th annual Downtown Forum on Transportation, Land Use and the Environment, held on March 1, 2019, at the Japanese American National Museum, White said an organization that doesn’t reflect its community will lose trust. “We’ve been making a concentrated effort that the folks that make up our outreach and leadership teams reflect the communities we go out and serve,” White said. “I don’t think it’s an accident that we have better relationships since 2014.” King County Transit, which most recently won the American Public Transportation Association award for outstanding transit system, makes more than 400,000 trips per day and has seen all-time high ridership as more people move into the Seattle area. Joining White were UCLA academics, government, nonprofit and private sector representatives sharing other real-word examples of how to tackle declining transit ridership, especially in an era of emerging new mobility services. The forum focused on successful public-private partnerships that could fill gaps [...]
Mario Gerla (front) and researcher on car-to-car communications networks (UCLA photo/Reed Hutchinson © 2007) Professor Mario Gerla MS ’70, PhD ’73, a pioneer in computer networks who had supervised more than 100 PhD graduates and served as chair of computer science at the UCLA Samueli School of Engineering during his long career, died on Feb. 9 after a prolonged battle with pancreatic cancer. He was 75 years old. Gerla was also affiliated faculty with the UCLA Institute of Transportation Studies because of his research interests in vehicular networks, such as car-to-car communications networks and urban sensing, and traffic management for congestion and pollution mitigation. “Over the past few years, Professor Gerla collaborated with transportation scholars across the UCLA campus and around the world on a number of innovative projects,” said Brian Taylor, ITS director and professor of urban planning at UCLA Luskin. “He was a warm and generous colleague, an exceptional scholar, and he will be deeply missed.” Gerla was born in Arona, Italy, in 1943 and grew up in Milan. He received an engineering degree from the Politecnico di Milano in 1966 and completed service in the Italian Navy following graduation. In 1969, he moved to the United [...]
Anne E. Brown completed her doctoral dissertation, a groundbreaking study of discrimination and travel patterns in ridehailing, at UCLA ITS in June. Before she starts as an assistant professor at the University of Oregon in the fall, she completed a brief but busy postdoctoral tenure putting her research into action. Dr. Brown spent the summer presenting her findings to influential local groups and in the media, culminating in a Sunday op-ed in the Los Angeles Times. "I found that when it comes to timeliness, technology and — most troublingly — racial discrimination, taxis lag significantly behind their flashy new competitors," Dr. Brown wrote, outlining her first-of-its-kind "equity audit" of Lyft, Uber, and taxis in Los Angeles. "Taxi service, while poor, was pretty much the same for white, Asian and Latino riders. It was only noticeably different — and noticeably worse — for black riders, providing robust evidence of discrimination." The equity audit found that black riders were 73 percent more likely to have a taxi driver cancel on them compared to white riders, a racial gap that shrank to just 4 percent for Lyft and Uber, among other findings detailed in Dr. Brown's column. The stark evidence of discrimination was covered [...]
Ridehail Revolution: Groundbreaking ITS dissertation examines discrimination and travel patterns for Lyft, Uber, and taxis
Ridehail services such as Uber and Lyft have revolutionized how people access cars. But research into where they travel and who they serve has been limited. For the past three years, ITS doctoral student Anne E. Brown worked to fill that gap in research by conducting a first-of-its-kind analysis of ridehail travel patterns, equity, and rider discrimination. Her dissertation has now been accepted and published, providing a groundbreaking look at ridehail use in Los Angeles. The newly minted Dr. Brown is the first scholar in the nation to access Lyft’s trip-level data — data that is not available to policymakers or the public — and analyzed rider travel and use patterns from more than 6.3 million trips taken in LA in 2016. She also conducted LA’s first audit study of Lyft, Uber, and taxi services, based on more than 1,700 rides, to measure how wait times and ride request cancellations varied across races, ethnicities, and genders. Her main findings include: Discrimination in the taxi industry results in higher cancellation rates and longer wait times for black riders. While taxi service overall was remarkably poor — 10 percent of taxis did not arrive within one hour — it was worst [...]
ITS and Global Public Affairs at UCLA Luskin co-hosted a lecture by Antoine Cormount, cities and digital technology chair at the Sciences Po in Paris, as part of the spring transportation speaker series. Courmont’s discussion, “Big Data and Re-composition of Urban Governance in the Digital Era: The Case of the Waze App,” focused primarily on the potential for conflict between public and private goals when firms and governments use different data sets.
