Associate Professor of Urban Planning Michael Manville spoke to Curbed about New York Gov. Kathy Hochul’s efforts to implement congestion pricing. By charging drivers to access Manhattan’s central business district, the congestion pricing system would feed $1 billion in annual revenue to the MTA, which could use the funds for improvements such as increasing bus and bike lanes and widening sidewalks. According to Manville, “Congestion is stopping us from making it a better kind of city for the vast majority of New Yorkers who almost never drive.” He also stressed the importance of creating a universal basic income system for eligible households in the region to ensure that the congestion pricing system is equitable. And he argued that “congestion pricing is actually great for drivers,” noting that the data collected can be used to improve the planning and pricing of parking. “People always want to overlook how much better [congestion pricing] can make driving,” he concluded.
Juan Matute, deputy director of the Institute of Transportation Studies at UCLA Luskin, spoke to Dot.LA about Superpedestrian, an e-scooter startup that aims to prioritize rider and pedestrian safety. Some e-scooter companies have faced lawsuits from riders over bodily injury and death. Superpedestrian says it has spent years improving its technology to protect vulnerable pedestrians and alert the user when they are breaking the rules. According to Matute, focusing on safety makes it easier for cities to adopt micro-mobility like e-scooter services. “Having self-regulating technology like Superpedestrian has is really attractive to cities because they can approve scooters to go in without worrying so much about users behaving badly,” he explained. “People have died because of vehicle system failures, brakes not being up to snuff.” Superpedestrian recently made its debut in Los Angeles with 5,000 LINK e-scooters.
Distinguished Research Professor of Urban Planning Donald Shoup was featured in a Bloomberg article arguing for the abolition of free parking. According to Shoup, drivers are subsidized at the expense of everyone else, and there is “no such thing as free parking.” He proposed pricing street parking according to market value, including desirability of the space, time of day and the number of open spots. Then, he suggested spending the revenue from street parking to better the surrounding neighborhoods. Parking is the most obvious way to make progress on issues including affordable housing, global warming, gender equity and systemic racism, Shoup said. Now, the pandemic has challenged modern notions about parking in America, with many parking lots converted into restaurant spaces and dramatic decreases in traffic. Shoup sees this as an opportunity to facilitate a dialogue about parking in order to make cities more equitable, affordable and environmentally conscious. “All parking is political,” he concluded.
Tierra Bills, an expert on the socioeconomic impacts of transportation decisions, will join the UCLA Luskin Public Policy faculty in January.
Bills’ research interests include equity analysis, travel behavior modeling, community-based data collection and transportation-performance measurement. In a joint appointment with the UCLA Samueli School of Engineering, she will teach two courses, “Transportation Equity” and “Travel Behavior Analysis and Forecasting.”
“Too often in the past, political expediency led to the routing of transportation systems like freeways and rail lines without adequate concern for their negative impacts on poorer, mostly ethnic neighborhoods,” UCLA Luskin Dean Gary Segura said. “The health and economic fallout of those decisions continues to have severe societal impacts, especially in congested urban areas. Future city planners and civil engineers alike will benefit from the expertise of Professor Bills in learning how to create more equitable transportation systems that avoid repeating past mistakes.”
Bills’ appointment as an assistant professor of public policy and civil and environmental engineering is part of a UCLA-wide “Rising to the Challenge” initiative spearheaded by the Ralph J. Bunche Center for African American Studies to expand the scope and depth of scholarship that addresses racial equity issues. Announced in June 2020 by Chancellor Gene Block and Executive Vice Chancellor and Provost Emily Carter, the program was established to help UCLA advance diversity, equity and inclusion. The plan includes the recruitment of 10 new faculty members over five years whose scholarly work addresses issues of Black experience.
“In order to help our students achieve technological breakthroughs that will improve the quality of life and society, we need to recruit faculty who understand the complex and entrenched inequities along racial and socioeconomic lines and address them in their research and teaching,” UCLA Samueli Dean Jayathi Murthy said. “Professor Bills brings the expertise at the nexus of engineering and public policy, which will greatly benefit our students as they tackle challenges in designing more equitable transportation systems.”
Bills is currently an assistant professor of civil and environmental engineering at Wayne State University in Detroit. Prior to that, she was a Michigan Society Fellow and an assistant professor at the University of Michigan, Ann Arbor. She has also served as a lecturer at Strathmore University in Nairobi, Kenya, and as a research scientist at IBM Research Africa, where she used data from smartphones to analyze the quality of transportation. Bills is a co-principal investigator on two current studies, funded by the National Science Foundation, focusing on transit issues in resource-constrained communities.
Bills received her B.S. in civil engineering technology from Florida Agricultural and Mechanical University and her M.S. and Ph.D. in civil and environmental engineering and transportation engineering from UC Berkeley.
Urban Planning Professor Anastasia Loukaitou-Sideris was featured in a Greater Greater Washington article about a proposal to temporarily ban people from public transit in Washington, D.C., if they are charged with sex or weapons offenses on the transit system. The Washington Metro’s safety board gave preliminary approval to the policy as a response to a significant increase in the number of reported sex offenses during the pandemic. In her research on harassment on transit, Loukaitou-Sideris has found that sexual harassment rates change based on environmental conditions. “Crimes like groping tend to happen in overcrowded buses or rail cars, while those committing indecent exposure tend to be emboldened when few people are around,” she explained. In one global survey, Loukaitou-Sideris found that 80% of women reported having been harassed on transit in the last three years. “That harassment, and fear of harassment, has real implications for mobility, particularly for women, LGBTQ folks and people of color,” she said.
Urban Planning faculty members Michael Manville and Brian Taylor spoke to the Los Angeles Times about the return of L.A. traffic levels to pre-pandemic levels. “Traffic is a product of people having places to go,” said Manville, but he noted that “it’s the last few vehicles on the road that are responsible for most of the delays.” Manville argued that congestion pricing is key to reducing traffic. “Traffic congestion arises because there’s excess demand and scarce road space,” he said. He also pointed out that congestion pricing can be used to increase equity “because the absolute poorest people don’t drive … [and] no one suffers from congestion more than people stuck on a bus.” Taylor added that “when traffic demand is near or above the capacity of the street and highway system, any changes — adding or subtracting relatively few cars — can have a significant effect on delays.”
Two centers housed at UCLA Luskin have received research awards from California 100, an ambitious statewide initiative to envision and shape the long-term success of the state.
The Lewis Center for Regional Policy Studies will evaluate current facts, origins and future trends in housing and community development, while the UCLA Institute of Transportation Studies will look into transportation and urban planning. In total, researchers from four UCLA organizations will spearhead three of the 13 California 100 research areas.
The Lewis Center will summarize California’s housing market and outline a vision for how policy changes could lead to a brighter future for the state’s residents, with a particular focus on increased equity and housing production. Working alongside cityLAB UCLA and the Terner Center for Housing Innovation at UC Berkeley, the Lewis Center team will also create a visualization of this future through creative techniques of diagramming, drawing and rendering to help readers picture the possibilities for California’s communities.
UCLA ITS will delve into transportation policy contradictions: California has invested substantially in public transit, while other public policies encourage driving and work against transit. As the state looks to meet its climate and equity goals, transportation systems — and the land use context surrounding them — will play a key role.
Research for both projects is slated to begin over the summer and be complete by December 2021, and will lead to a set of policy alternatives for the future of California. The policy alternatives will be developed in conjunction with research teams from the other California 100 issue areas.
The California 100 Commission is a multi-generational advisory body that will develop recommendations for the state’s future and test those recommendations across a broad set of policy areas by directly engaging Californians.
“From climate change to aging populations and rapid changes in industry, California will face enormous challenges in the years ahead,” said Kathrick Ramakrishnan, California 100 executive director. “We are fortunate to be able to draw on the deep talent of researchers in California to produce evidence and recommendations that will inform robust public engagement and set the state on a strong, long-term trajectory for success.”

Associate Professor of Urban Planning Adam Millard-Ball joined an episode of Malcolm Gladwell’s podcast “Revisionist History” to discuss the future of autonomous vehicles. The safety of autonomous vehicles was originally framed as a technological challenge that required a programming solution, but the main issue is actually the people outside the vehicle, Millard-Ball explained, beginning at minute 26:50. “If you are a pedestrian and you have that confidence that the autonomous vehicle is going to stop and yield to you as it legally should, then there is nothing to stop you from taking the right of way,” he said. Autonomous vehicles are programmed to maximize caution, which allows the pedestrian to make the first move instead of waiting to see what the car will do. “The more unpredictable a pedestrian appears, the autonomous vehicle will recognize that unpredictability and be more cautious,” he explained. Autonomous vehicles allow for a role reversal where the vehicle caters to the pedestrian’s erratic behavior.
With cities and suburbs across the United States facing well-documented affordable housing shortages, researchers for years have studied how government planning standards affect housing costs.
Those studies often examine how planning and zoning decisions affect traffic noise, whether neighborhood amenities can be reached by foot and other factors that can make a home more or less valuable.
A new paper expands this body of research by considering the housing, schools, parks and other infrastructure that go unbuilt in favor of wide streets.
The U.S. has some of the widest streets in the world. In 20 of the most populous counties, the median residential street plus sidewalks is 50 feet wide, with the dollar value of land used for streets sometimes stretching into six figures, according to the research in the Journal of the American Planning Association.

Wide streets are less common in some other countries. Certain streets in Japan, for example, are much narrower. Developments in Tokyo since 1990 have average street widths of 16 feet, noted Adam Millard-Ball, an associate professor of urban planning at the UCLA Luskin School of Public Affairs and author of the new paper.
“One of the best ways to alleviate the housing crisis is to build more housing,” he said. “To the extent that narrower streets allow developers to build more housing, that will address the No. 1 issue with housing right now.”
The median residential street in Arizona’s Maricopa County, which includes Phoenix, is 50 feet wide, according to Millard-Ball’s sample of counties.
The median width of a residential street in Middlesex County, Massachusetts, which includes Cambridge, is 40 feet — the narrowest of the group.
The widest streets in the sample are in Cook County, Illinois, which includes Chicago. There, the median residential street is nearly 65 feet wide.
The 50-foot standard
For urban planners, a street is called a right of way. The paved section is the roadway.
A right of way includes the roadway as well as sidewalks, if any, along with space for drainage, utility poles and other public infrastructure. It’s the land usually owned by a city or county that the public has the right to use and make its way through by car, bicycle, foot or other mode. Neighbors waving hello across the sidewalk’s edge of their properties are waving across the right of way.
The median 50-foot right of way Millard-Ball documents stems from nearly a century of history in U.S. planning. After the home mortgage system collapsed during the Great Depression, the federal government stepped in and established the Federal Housing Administration in 1934.
The agency’s mortgage insurance and financial assistance for homebuyers represented “the most ambitious suburbanization plan in United States history,” wrote Michael Southworth and Eran Ben-Joseph in a 1995 Journal of the American Planning Association article that reviews the historical rise of U.S. suburbs.
To protect the government’s unprecedented investment in home ownership, mostly for white Americans, developers had to have detailed plans approved by the agency. The agency encouraged cul-de-sacs for new developments and favored plans that discouraged through traffic.
“Moreover, the FHA, unlike other planning agencies, was largely run by representatives of real estate and banking, so developers felt that its intervention protected their interests,” Southworth and Ben-Joseph wrote.
If developers wanted to build homes that would benefit from federal financial backing, rights of way had to be at least 50 feet wide, Millard-Ball explained in his new paper, “The Width and Value of Residential Streets.”
Six-figure values
To understand the value of land used for streets, Millard-Ball drew on research from the Federal Housing Finance Agency that estimates the value of quarter-acre lots zoned for single-family homes across the country. The value of the land used for streets can be substantial in places where low population density and high housing costs converge.
Santa Clara County, California, which includes San Jose, has the most valuable streets in the sample at $146,000 per tax parcel. That’s roughly 40% of the median price of an existing single-family home sold in the U.S. in April 2021, according to data from the National Association of Realtors.
“One of the best ways to alleviate the housing crisis is to build more housing. To the extent that narrower streets allow developers to build more housing, that will address the No. 1 issue with housing right now.”
— Adam Millard-Ball, UCLA Luskin
New York City, by contrast, has high housing costs but also high density — large apartment buildings are common. Tens of thousands of people live within each square mile. The land beneath streets in Queens, for example, is worth $36,000 per parcel.
At the other end of the value spectrum, streets are worth $7,000 per parcel in Bexar County, Texas, which includes San Antonio. But land values and street widths can vary greatly within counties.
Terra Vista, a small street in a subdivision 25 miles north of San Antonio, is 52 feet wide and has a land value of $43,288 per parcel. All the land under residential streets in Millard-Ball’s 20 counties is worth nearly $1 trillion in total.
Millard-Ball noted that street land value estimates per parcel are likely low for high-cost, dense cities, which often zone for multifamily buildings over single-family homes.
For example, an Italian specialty food store in the Mission District of San Francisco sold its parking lot for $3 million in 2018 — roughly $36 million per acre, by Millard-Ball’s calculation — to make way for a five-story, 18-unit building, according to the news site Mission Local.
Most U.S. counties regulate how and where new housing and business developments are built, according to the National Association of Counties, a nonprofit organization that represents U.S. county governments.
Many large cities do the same.
It would be overly costly for cities and counties to change the width of existing streets, particularly with local governments facing budget shortfalls during the pandemic.
Still, the estimates in the new paper can be instructive for planning officials in places like Bexar, one of the fastest growing counties in the U.S., as they permit developments to accommodate new and current residents.
“The values are an indication that cities should be making it easier to use streets for something other than roadways and parking,” Millard-Ball said. “A good analogy is that during COVID, one use of streets has been for outdoor dining. It’s recognition that this land is more valuable to the community if we can use it for people to get together and eat in a safer environment outdoors, than as a parking space or travel lane for cars.”
He continued: “The point is that desolate asphalt is doing nobody any good — not the city, not property owners, not anyone. Cities are often keen to widen the right of way with new developments. Say you want to develop a new apartment building. Often, the city will say, ‘Sure, but you have to give up some land so we can add a turn lane, or widen the sidewalk.’ If cities can widen the right of way, why can’t they narrow it in exchange for improvements that will benefit the public?”
Indeed, when a new residential building goes up, cities commonly require developers to widen streets, according to a 2017 paper in the Journal of Transport and Land Use by Michael Manville, another UCLA Luskin urban planner.
In the paper, Manville looked at how the requirement played out in Los Angeles from 2002 to 2012. He found the city’s predictions of increased traffic with the arrival of new buildings were often wrong, and “the standards the law is based on are in some ways unverifiable. Thus the law likely does little to reduce congestion and probably impedes housing development.”
Flexible design
City and county planning standards vary and change, but the federal 50-foot standard still often dominates residential street design. Still, it’s not always true that counties with more land to expand, like those in Texas, have wider streets. Dallas County, for example, specifies that new residential streets in subdivisions be at least 50 feet wide. The median width of residential streets there is exactly 50 feet, Millard-Ball finds.

Residential streets in Chicago, meanwhile, are typically 66 feet wide, according to city design standards. That roughly matches the length of the typical surveyor’s chain as the city grew throughout the 1800s and early 1900s. The surveyor’s chain was a tool made up of interlocking metal bars that land surveyors used to measure and mark the shapes of streets to be built.
Uniformity in street design made sense as the nation was expanding and infrastructure technologies were less advanced. But the takeaway for Millard-Ball is that maintaining rigidity in street design means fewer amenities and, potentially, less housing.
He wonders, for example, whether more streets could be built with parking cutouts only where there are no private driveways — providing a unique residential landscape alongside opportunities to use more of the built environment for activities other than driving.
“That would make construction drawings more complex,” Millard-Ball said. “The tradeoff is visual interest — and saving a lot of valuable land.”
The prospect of narrower streets raises the question of whether emergency vehicles would be able to pass, though some planners, and at least one report from the U.S. Department of Transportation, suggest smaller emergency vehicles could be an answer.

Urban Planning Professor and Director of the Institute of Transportation StudiesBrian Taylor spoke to the Los Angeles Times about changing traffic patterns in Los Angeles as COVID-19 restrictions are lifted and life returns to a post-pandemic normal. The pandemic altered traffic and transit patterns, with many businesses transitioning to remote work. As the economy reopens, traffic levels have increased, but the next few months will signal how long-lasting the pandemic’s impact on traffic patterns will be. Vehicle travel is increasing in part because more businesses and activities are opening up, prompting people to drive more often and farther from home. Taylor explained that congestion is “spatially and temporally” structured, meaning that it occurs when many travelers are going to the same destination at the same time. “If we go back to pre-pandemic living and working patterns, driving and traffic levels are likely to be similar to before,” he said.
