Manville on East Coast Traffic Relief

/0 Comments/in /by

Michael Manville, associate professor of urban planning, spoke with WGBH News in Boston about a proposal to add dedicated toll lanes on Massachusetts’ major highways. As the state considers options to alleviate traffic during rush hour, Gov. Charlie Baker has come out in support of adding “managed lanes” that let drivers choose whether to pay a fee for a quicker commute. “While drivers have a choice to commute in a faster lane for a cost, drivers who remain in the un-tolled lane will also experience lighter volume from those who peel off for the faster lane,” the governor explained. Manville said the benefits of creating such lanes are clear. “Almost anytime these managed lanes have been put in, you see traffic flowing much more smoothly, delay going down and many more vehicles being moved in these managed lanes. They are, at this point, a proven intervention,” he said.

The Traffic Bogeyman Is Us, Manville Says

/0 Comments/in /by

Michael Manville, associate professor of urban planning, spoke to LAist about a study examining the impact that Uber and Lyft have on road congestion. The study, which was commissioned by the rideshare services, found that they accounted for 2 to 3 percent of all vehicle miles traveled in Los Angeles County in September 2018. “If [Lyft and Uber] have confessed to slowing you down while you are in traffic, then they have confessed to sharing in the crime that you are also committing,” said Manville, a faculty fellow with UCLA Luskin’s Institute of Transportation Studies. Manville said his colleagues like to joke that a more interesting study would be to look at how much Ford and Toyota contribute to traffic congestion. “It’s fun to blame tech companies for things — they’re really easy to dislike — but congestion is something that we all cause,” he said.

Manville on the ‘Unmitigated Disaster’ of Parking Requirements

/0 Comments/in /by

Michael Manville, associate professor of urban planning, spoke with Curbed LA about a proposal to eliminate parking requirements for newly constructed apartment and condo buildings in downtown Los Angeles. Parking minimums have been “an unmitigated disaster,” Manville said. “Right now, it’s illegal to build for a tenant who doesn’t care if their car is in the same building with them” or who doesn’t own a car at all, he said.  The requirement to include parking spots in residential buildings has been blamed for higher housing costs, the construction of unsightly garages and the exacerbation of climate change. “When you require parking, you really do encourage driving,” Manville said. Removing the parking requirement is an “absolutely necessary” step, one of many needed to help Angelenos drive less, he said.

Manville on Lessons From the Measure M Campaign

/0 Comments/in /by

An article on Streetsblog USA featured a report authored by Associate Professor of Urban Planning Michael Manville on the transit funding initiative Measure M. Voters approved the measure overwhelmingly in 2016, largely due to a political campaign that focused on boosting the economy and easing traffic, but not on transforming the region’s car culture, the report noted. “Voters were expressly not offered a vision of a more multimodal or environmentally sustainable Los Angeles; they were mostly offered instead a vision of more jobs, better roads and easier driving,” Manville wrote. The transportation investments ushered in by Measure M have not led to higher use of public transit. “Los Angeles has a hard road in front of it in making the vision of Measure M a reality,” the report said. “An electoral victory is the end of a political process, but only the beginning of a policy process.”

L.A. Parking: How Did We Get Here?

/0 Comments/in , , /by

When LAist set out to create a primer on the lightning-rod issue of L.A. parking — why it’s so exasperating, how we got here and where we are headed — it went straight to the experts at UCLA Luskin: Juan Matute, deputy director of the Institute of Transportation Studies; Donald Shoup, distinguished research professor of urban planning; and Associate Professor Michael Manville. As our reliance on cars grew in the years after World War II, minimum parking requirements were seen as essential, Matute said. Now, instead of too little parking in L.A., there is too much, Shoup argued. Some cities are relaxing parking requirements for new housing in high-density areas. After analyzing one such program, Manville found that it led to lower costs and more parking flexibility. The primer also cited Shoup’s book arguing that there is no such thing as free parking — the costs are just passed along to the entire community, including nondrivers.

Manville, Lens and Monkkonen on ‘the Consequences of Inaction’

/0 Comments/in , , /by

A CityLab article on housing supply as a hot-button issue delved into the robust debate around the best strategies to make shelter affordable. Los Angeles is the epicenter of the housing crisis, and UCLA Luskin urban planning scholars have conducted extensive research on the issue, with varying conclusions. The article described arguments made for and against upzoning, which would increase the housing stock by lifting regulatory limits on density. In an earlier article, Professor Michael Storper cast doubt on the effectiveness of such policies. In rebuttal, three of his UCLA Luskin colleagues, Associate Professors Michael Manville, Michael Lens and Paavo Monkkonen, authored an essay pointing to studies that support upzoning. “When every neighborhood acts to preserve itself, soon the city is mired in regulation, and rents and prices rise,” they wrote. “Were regulations relaxed, these places would have more housing, and price increases would first slow and eventually fall.” They concluded, “The consequences of inaction also matter.”

Transit Ridership Still in Decline, Manville Reports

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to Transit California about a 2018 report he co-authored with other Institute of Transportation Studies (ITS) scholars that found public transportation ridership in Southern California has declined. Manville confirmed this trend has continued with one difference. “What is different from then to now is that San Francisco has now joined the ranks of ridership in decline, which was not the case when we originally did the study,” Manville said. Despite political support for Measure M, which created a tax in Los Angeles to pay for transit improvements, ridership remains low. The measure appealed to voters — but not enough to change their travel behavior, Manville said. “We can’t depend or model transit ridership on low-income riders. That model falls apart today,” he said. “Instead, transit has to be built in a way that we expect people to ride it.” Urban Planning Professors Brian Taylor and Evelyn Blumenberg coauthored the 2018 report.

Manville on Elon Musk’s Vegas People-Mover

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to the Los Angeles Times about Elon Musk’s underground people-mover for the Las Vegas convention center’s expansion. Musk’s Boring Co. secured a $48.7-million contract after the Las Vegas Convention and Visitors Authority board approved construction of the roughly mile-long transit loop. Manville was surprised to learn that an underground plan was more affordable than a proposed elevated rail because tunneling is often more expensive. Based on the few details released by the Boring Co., Manville said it would be difficult to assess the project. “This is kind of a market test for him. Can he now build something that is more commercially viable than what he’s done with his test tunnel in Hawthorne?” Manville said. “But there’s nothing intrinsically interesting about building a tunnel to move people around. That’s what a subway is, right?”

SB50 Would Have Helped Ease Housing Crisis, Manville Says

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville weighed in on the controversial Senate Bill 50 in a recent Los Angeles Times column. SB50 aims to relieve the housing shortage, reduce commuting time and combat climate change by requiring cities to allow multi-family complexes to be built in areas near mass transit, among other provisions. Many California residents have expressed concern that SB50 would increase housing density and destroy the integrity and character of their neighborhoods. Manville understands the concerns of residents but believes that everyone must contribute to solving the housing crisis, including those living “smack dab in the middle” of the nation’s second-largest city. “We have people in our city living in tents. They live in their cars. They live under our highway overpasses and they die on our sidewalks,” Manville said. “At a certain point, the pedigree of your house has to matter a little bit less.”

More Is Less on L.A.’s I-405, Michael Manville Says

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville is quoted in a StreetsBlog USA article on worsening traffic congestion in and around Los Angeles, especially in the Sepulveda Pass. The completion of the I-405 Sepulveda Pass Improvement Project in 2015 was projected to alleviate congestion, but studies have shown that traffic is worse despite the addition of an extra lane. This phenomenon, known as the law of induced demand, explains how travel time on the pass during rush hour has gone up by 50 percent in the past four years. According to the theory, when the supply of a good (in this case traffic lanes) is increased, more of that good will ultimately be consumed. “So you have a road that is every bit as congested, just wider,” Manville said. On possible fixes for the problem, Manville explained that establishing a toll system may be the best way to combat traffic: “When you do price the road, people switch to transit.”
