Manville on Angelenos’ Road Habits Under Coronavirus Restrictions

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to the Guardian about Angelenos’ road habits during the time of coronavirus. Even when just a few businesses asked workers to stay home, congestion was down quite a bit, demonstrating how relatively small reductions in cars can generate big increases in road performance, Manville said. “That has lessons for us, because it does remind us that when things get back to normal, policies that nudge just a few people away from a trip at a busy time can have a huge impact,” he said. However, Manville doubted the current health emergency would reshape Angelenos’ long-term relationship to the road. “It would be one thing if we were under an order to still go to places, but not in cars — some of us would find we like walking or biking,” he said. “But there’s no reason to think we will develop a different travel habit while we’re sitting on our couches.”

Manville Links Poverty, Car Access and Transit

/0 Comments/in /by

A New Geography article on the links between car access and poverty summarized the conclusions of a paper co-authored by Associate Professor of Urban Planning Michael Manville. The paper, which was published in the Journal of Planning Education and Research, argued that proximity to transit does not necessarily correspond with transit use and effectiveness. While 89% of workers live “near transit” in Los Angeles, only 5% of Los Angeles commuters use transit. Furthermore, Manville and co-authors David King and Michael Smart found that U.S. households without access to vehicles have a 70% greater chance of being in poverty than those that have access to vehicles. In addition, they found that the incomes of households without vehicles rise at a lower rate than households with vehicle access. The authors pointed to door-to-door access as the ultimate solution and concluded that universal auto access would lead to less unemployment, less poverty and higher standards of living.

Shoup on Battle Over Street Parking in Manhattan

/0 Comments/in /by

A New York Times article on a Manhattan transportation panel’s proposal to do away with free street parking in a 50-block stretch of the Upper West Side cited Donald Shoup, distinguished research professor of urban planning. New York City has installed miles of bus and bike lanes and banned cars from a major thoroughfare. Next year, it will start charging drivers in Manhattan’s most congested zones. Some drivers feel unfairly targeted, while many transportation advocates say car culture has been unjustly subsidized for too long. Shoup, who has long promoted pricing as a way for cities to manage parking demand, noted that New York is the only major city in the country that does not have some form of residential parking permit. Such permits are meant to let people with cars park near where they live and keep outsiders out.

Manville on Public Transit Investment and Ridership Trends

/0 Comments/in /by

In a San Diego Union-Tribune article about the city’s new high-speed rail proposal, Michael Manville, associate professor of urban planning, highlighted the challenges of implementing public transportation improvements in cities primarily designed for automobile travel. San Diego recently proposed two tax increases to fund billions of dollars in bus and rail investments, but experts worry that it will follow the example of cities like Atlanta, Houston and Los Angeles, which invested heavily in public transit only to lose riders. Manville describes Los Angeles as a “cautionary tale,” explaining that “you can’t take a region that is overwhelmingly designed to facilitate automobile travel and change the way people move around just by laying some rail tracks over it.” To avoid decreases in ridership, transportation experts recommend making it harder to drive by eliminating street parking, ending freeway expansions, limiting suburban home construction and implementing policies like congestion pricing.

Manville Imagines Transit-Oriented Future of Cities

/0 Comments/in /by

In a National Geographic article exploring transit-oriented development in cities across the globe, Associate Professor of Urban Planning Michael Manville commented on the challenges facing Los Angeles. The article focused on architect Peter Calthorpe, who highlights the negative effects of car-oriented urban environments on climate, air quality and congestion, in addition to time and money wasted by drivers. Urban planners look to transit-oriented development to remake healthy urban spaces and reverse the damage caused by dependence on automobiles. Calthorpe imagines an urban utopia where cities would stop expanding, pave less and heat the air and the planet around them less. He recommends dense clusters of walkable communities around a web of rapid transit to support a growing population. Manville weighed in on the urban environment of Los Angeles, where residents continue to rely on cars despite efforts to improve public transit. The conundrum, Manville said, is that “driving’s too cheap [and] housing’s too expensive.”

Wachs Explains Lack of One-Way Streets in Los Angeles

/0 Comments/in /by

In an LAist article, Urban Planning Professor Martin Wachs commented on the history behind the lack of one-way streets in Los Angeles compared to East Coast cities. Los Angeles built wide roads to accommodate the automobiles and streetcars popular in the first half of the 20th century, Wachs said. The wide streets and long blocks characteristic of Los Angeles would make one-way streets difficult, he added. Los Angeles experimented by converting Pico and Olympic to one-way streets to ease traffic for the 1984 Olympics, but complaints from residents and business owners resulted in the restoration of two-way traffic. “One-way streets tend to work best when blocks are short and streets are narrow, so cars can easily loop around to reach their destination. When there are five or six lanes of traffic, like Venice Boulevard, cars have to merge over too many lanes to make a turn and the flow of traffic gets messy,” Wachs explained.

Manville’s Research on Universal Auto Access Published

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville’s research on “The Poverty of the Carless: Toward Universal Auto Access” was published in the Journal of Planning Education and Research. Manville and co-authors David King and Michael Smart investigated how vehicle access inequity affects low-income American households. In a society where vehicle access is becoming increasingly necessary, “anyone who can acquire a vehicle will, even if doing so is financially burdensome,” the study explained, noting that “only the most disadvantaged people [are] unable to afford cars.” The research found that “U.S. households without access to a vehicle have steadily lost income, both in absolute terms and compared to those with cars, as the landscapes around them were increasingly shaped to favor the automobile.” Facing objections to universal auto access due to factors such as carbon emissions, the study argued that, “like water and heat, access to cars should be guaranteed and perhaps subsidized for low-income households.” While the long-term goal should be to decrease driving overall, the status quo is comprised of a “small group of people who need vehicles and lack them and a large group who have vehicles and use them needlessly.” Manville and his co-authors recommended treating vehicles as essential infrastructure and working to close gaps in vehicle access for poorer Americans while aiming to decrease overall consumption by the more affluent in the long term. The research was featured a recent Planetizen article and in a Q&A with co-author King. — Zoe Day
