A Fee to Ease Manhattan Traffic

News outlets covering New York City’s plan to charge a congestion fee to drivers entering the most traffic-choked parts of Manhattan called on UCLA Luskin transportation experts to provide insight. Donald Shoup, distinguished research professor of urban planning, told Gothamist that New York is unusual in that nearly all of the curb spaces are unmetered. “This is some of the most valuable land on earth, and you could use it free if you bring a car,” he said, calculating that the city could generate $6 billion annually by charging $5.50 a day for every free curb parking spot. Urban Planning chair Michael Manville told the Associated Press that American cities should take heed of London’s experience, where several exemptions to a congestion pricing program have contributed to the return of clogged streets. “There’s always going to be carve-outs,” he said. “But the further and further you start going down that road, there lies madness.”


 

I-15 Expansion Highlights Tension Between Commerce, Climate Goals

Michael Manville, chair of Urban Planning at UCLA Luskin, spoke to the Los Angeles Times about the approval of a freeway-widening project on Interstate 15. Truck movement along the I-15 is a major driver of the region’s economy, and the project highlights the friction between efforts to expand infrastructure to accommodate commerce and the state’s ambitious climate goals. Now, federal officials are looking into allegations that state and local officials mischaracterized the potential harm the project could cause communities that breathe in some of the nation’s worst air. Proponents of the I-15 expansion had argued that new lanes would speed up commutes, but critics said the opposite was true, that making more space for vehicles would draw even more drivers, increasing congestion and pollution. Traffic modeling studies can be used to say what you want them to say, Manville said. “From the moment we first started using these models many decades ago, they have aspects of being a black box.”


 

Political Courage Is Key to Curing Traffic Ills, Manville Says

UCLA Luskin Urban Planning chair Michael Manville spoke to the Los Angeles Times about plans to tap into artificial intelligence to find ways to make California’s roads safer and less congested. Caltrans is asking tech companies to pitch generative AI tools that could analyze immense amounts of data quickly, perhaps helping the state’s traffic engineers make decisions on signal timing and lane usage. Manville said that the problem is not a lack of data-backed solutions but rather a lack of political courage to put existing solutions, such as congestion pricing, into play. “If you want to make cities safer for pedestrians, if you want to lower speeds, if you want to deal with congestion in a meaningful way, technology is not going to rescue you from difficult political decisions,” he said.


 

Blumenberg on Affordable Housing, Long Commutes

Evelyn Blumenberg, director of the Lewis Center for Regional Policy Studies at UCLA Luskin, spoke to the Los Angeles Times about the tradeoff between affordable housing and long commute times. Census data highlight two Los Angeles County areas where commutes are especially long: South Los Angeles and the San Fernando Valley. Blumenberg said residents of South L.A. typically live far from their workplaces and often lack serviceable public transit options. As for the Valley, “it’s a pretty dispersed environment and it takes a long time to get to destinations,” she said. Blumenberg noted that while more people are working from home, there has been an increase in traffic from delivery vehicles, such as Amazon trucks and cars used by UberEats. Congestion is currently less severe at peak hours but more widespread over the course of the average day, and “my hunch is that some of these new patterns are here to stay,” she said.


 

Reducing the Risk of Collision Between Cars, Cyclists

A Los Angeles Times article on “dooring,” the collision caused when a car door is opened in front of an oncoming cyclist, cited Madeline Brozen, deputy director of the Lewis Center for Regional Policy Studies at UCLA Luskin. The impact can lead to serious injuries, and cyclists and transit advocates call for greater awareness and better road infrastructure to reduce the risks. Some roadways feature green bike lanes, but Brozen said “protective infrastructure” — buffer zones that separate cyclists from parked cars and traffic — would further increase bicycle safety. At issue is the “political battle over convenience or delay for vehicles over the safety of people biking and walking,” Brozen said. “It’s really at the whim of the council member and the council member’s office to decide whether they’re willing to take on those battles or not.”


 

Taylor on the Addition of New Toll Lanes on the 405

Brian D. Taylor, director of the Institute of Transportation Studies at UCLA Luskin, spoke to the Orange County Register about the opening of new express lanes on the 405 Freeway. Motorists who use the two express lanes on 16 miles of the freeway in Orange County will have the option of paying a toll or carpooling. The lanes will be free to three-person carpools, but two-person carpools during rush hours will need to pay. Taylor, a professor of urban planning and public policy, said express lanes help keep traffic flowing compared to general lanes. For example, the two express lanes on the 91 Freeway carry about 45% of its total traffic. “Those two lanes are operating so much more efficiently that more people are getting through as a result,” Taylor said.


 

Taylor on Angelenos’ Travel Choices During Freeway Closure

Brian Taylor, director of the Institute of Transportation Studies at UCLA Luskin, spoke to LAist about how Angelenos coped with the temporary shutdown of the 10 Freeway. “If one piece of our network goes down, there’s a lot of opportunities for people to make changes and move around those things,” said Taylor, a professor of urban planning and public policy. “People adjust their behavior by changing their routes, changing the time of their travel, and changing the mode by which they travel, in that order.” Now that the freeway has been reopened, it’s unlikely these changes will stick, he said. The disruption may have had the positive effect of making people more aware of their commuting options, he said, “but it’s unlikely that the event itself … might cause people to reconsider their travel choices.”


 

A Freeway Closure That Reverberates Around the Region

Michael Manville, chair of Urban Planning at UCLA Luskin, spoke to the Los Angeles Times about the traffic disruption caused by the closure of the 10 Freeway after a massive fire. Freeways carry a hugely disproportionate share of L.A. traffic, Manville said, and “when there are big interruptions to them, they really do have effects that reverberate around the region.” About 300,000 vehicles on average move through the affected stretch of the 10 Freeway each day, and officials at L.A. Metro have been working to entice affected commuters to try public transit. Manville said he is not confident that people will change their commute habits over the long term. “Most people’s experience with the freeway at rush hour is already pretty miserable — and that does not drive a lot of people to public transportation,” he said. “I think most people in Los Angeles understand that we are over-reliant on a bunch of roads that don’t perform well because they’re overused.”


 

Manville on Road Tolls: ‘There Is No Other Way to Reduce Congestion’

Michael Manville, associate professor of urban planning at UCLA Luskin, spoke to the Los Angeles Times and KTLA and KNBC about an expected pilot program that would charge a toll on some Los Angeles roads. The program aims to ease traffic congestion, reduce carbon emissions and raise funds at a time when gas taxes are down due to the surge in electric vehicles. Manville said that revenues can and should be used to ensure that low-income drivers are not disproportionately burdened by the tolls. Some businesses are concerned that drivers who want to avoid paying freeway tolls will clog local roads; others argue that safety and convenience issues continue to surround many public transit options. Manville said charging a premium toll during peak hours would reduce traffic as well as the risk of crashes. “There is no other way to reduce congestion,” he said. “So you can do something like this or basically you can just live with congestion.”


 

Manville on Proven Strategies to Improve Transportation

News outlets from around the country turn to Michael Manville, associate professor of urban planning, for insight into transit and land use issues. Manville spoke to the Los Angeles Times about a question Mayor Karen Bass must consider: Should train and bus rides be free? History shows that this strategy to increase ridership on public transit can work, Manville said. In the San Diego region, a $160-billion plan to expand the rail system includes road charges that will levy a per-mile fee on drivers. “If you design the road-user charge correctly, some of the biggest beneficiaries will be drivers,” Manville told the San Diego Union-Tribune. In Kentucky, an attempt to ease congestion by adding lanes to highways is misguided, he said. “The typical highway widening project has costs that exceed its benefits and probably shouldn’t be done,” Manville told Louisville Public Media, noting that adding tolls is the only proven way to consistently reduce congestion.
