Lecture Recap: Measuring the Economic Impact of Street Improvements in New York City

Eric Lee, the president of management consulting firm Bennett Midland LLC, visited the Lewis Center this week to present his firm’s innovative work regarding the economic impacts of reallocation of street space in New York City for dedicated bikeways, pedestrian improvements, and bus lanes.

Mr. Lee first set the stage by showing pictures of the types of projects considered in the study. Quite dramatic changes, such as parking-protected bikeways and the conversion of parking into pedestrian plazas, have taken place in New York City in recent years. Mr. Lee’s research concerns the question, “Will these changes hurt economic activity?”

Mr. Lee’s presentation was an overview of the study methodology and findings. Sales tax receipts provided a direct and impartial measure of economic activity. Mr. Lee’s firm compared sales tax receipts on 11 study corridors with comparison corridors — chosen by a typology to have similar scale and use — as well as with borough-wide sales tax data. Only retail and service-oriented businesses were included in the analysis, because these businesses depend upon customer access (whether by private vehicle, bus, bike, or walking). Mr. Lee displayed some examples of graphs showing retail sales tax receipts over the course of the study. Tax receipts on a study corridor, a comparison corridor, and borough-wide receipts would be shown on the graph, offering the audience an immediate visual of how the corridor’s economic activity compared. These graphs included a data point for every quarter and extended for several years. Mr. Lee emphasized the ultimate finding of the study: 8 out of 11 study corridors outperformed comparison sites, which indicates that street improvements “do no harm” to economic activity.

A long and lively […]

2013 Lake Arrowhead Symposium Focused on Smart Technologies, Smart Policies

On Sunday, October 19, policymakers and thought leaders from around the country convened in Lake Arrowhead, CA for a three-day symposium on the relationship between technology, data, transportation and land use planning, and the environment. The event, entitled “Smart Technologies, Smart Policies” is the 23rd annual installment in a series of relatively intimate, carefully curated symposia convened by the UCLA Lewis Center for Regional Policy Studies. This year, the panels dealt with such questions as: How can the public sector be responsive to the fast-pace and great uncertainty that technological change presents? How are city governments using more data and new technologies to plan and manage transportation systems in innovative ways, from smart parking meters to taxicab GPS to open transit data feeds? What new institutions, regulations, and systems are needed to deal with a changing technological world?   To view the entire photo set, please visit our Arrowhead Flickr gallery

Lecture Recap: Driving Detroit: The Quest For Respect In The Motor City

Professor George Galster, of Wayne State University, visited the Lewis Center this week to present a vibrant summary of his new book, “Driving Detroit: The Quest for Respect in the Motor City.” Speaking to a full room of students, faculty, staff and Luskin School guests, Galster offered his insight into how Detroit arrived at its current dysfunctional metropolis. His analytical framework used basic psychological principals to examine how Detroit’s residents quest for securing physical, social and psychological resources contributed to this deterioration. Galster demonstrated this framework with a series of examples, including the “chain of moves” whereby developers continually built new housing on the ever-expanding urban fringes, encouraging residents to persistently purchase a home in a nicer neighborhood than where they currently live. As this cycle continues, the urban core is left to decay, creating an environment where 30% of land is now vacant, leaving dire consequences to the physical and economic environment. He attested this and other rational choices made by individuals, when combined, are collectively irrational.

Throughout his talk, Galster demonstrated moving use of language, once describing an abandoned automotive assembly plant as the “fossilized bones of an industrialized dinosaur.” The question and answer session, following an excellent lecture, expanded the discussion to cover gender struggles, pension issues, urban agriculture and a slew of other topics, which Galster continued to address in a thoughtful and informative matter.

The Lewis Center would like to extend our gratitude to Associate Director and Urban Planning Professor, Michael Lens, for bringing Professor Galster to speak at the Luskin School of Public Affairs. Professor Galster’s book “Driving Detroit: The Quest for Respect in the Motor City” is available now.

Lecture Recap: Analyzing Pedestrian Movements in Israeli Cities

This October, Dr. Yodan Rofe visited UCLA to present his work developing a model for pedestrian activity in Israeli cities. Speaking to a full audience, he discussed the state of the practice in pedestrian modeling and the goals and results of his work in Israel. Dr. Rofe cited the work of Jane Jacobs, Kevin Lynch, and Jan Gehl as theoretical predecessors. He defined and explained the “spatial configuration approach” to travel modeling, which draws on the work of Hillier and Hanson, who pioneered this concept in 1989 with their book The Social Logic of Space. This approach entails formalizing the street network in a city as a set of links and nodes, and assigning values to these links and nodes based upon various measures of their centrality and connectedness in the network.

Dr. Rofe’s work, funded by a national authority in Israel, aims to identify the variables explaining pedestrian volumes in Israeli cities, with a particular emphasis on understanding the movements of children and elderly people.  Dr. Rofe’s team conducted pedestrian counts on a representative sample of streets, and then performed a regression analysis to explain pedestrian volumes. His team constructed both city-scale models and neighborhood-scale models, and found that the neighborhood-scale models had greater explanatory power. His team modeled total pedestrian volumes, as well as volumes of children and elderly walking, and found more success modeling total numbers of pedestrians.

Dr. Rofe finds that the models are moderately successful: they can predict pedestrian movements relatively well in some types of cities and neighborhoods (R^2 > 80%), and much less well in other cases, such as when focusing only on children or the elderly, or when predicting movements […]

Lewis Center Faculty Lead Study on Impacts of Housing Boom

In the heady years before the Great Recession, did cities and municipalities get carried away with boomtime spending? Once the downturn hit, how prepared were local governments to face suddenly pressing needs in their communities?

Urban Planning professors Paavo Monkkonen and Michael Lens plan to address these questions as they lead a three-year, $610,000 study aiming to better understand the behavior of local governments during times of economic upheaval. By painting a clearer picture of how local leaders spent in the good times – and how they cut back in the bad – the researchers aim to help smooth the impacts of future booms and busts on local economies.

The project team includes Larry Rosenthal, of UC Berkeley’s Goldman School of Public Policy, and Tracy Gordon of the White House Council of Economic Advisers.

Since cities and municipalities provide basic services such as police, fire, streets, parks and schools, their financial health has a direct impact on their ability to deliver high-quality housing and neighborhoods for their residents. As the housing bubble grew, local governments may have been tempted by rising property tax revenues and the perception that growth would continue to make unsustainable spending and investment decisions. As these revenues disappear, the shock to overextended resources is resulting in drastic cuts, possibly deepening the recession’s impact and slowing long-term growth.

The project, officially titled “Irrational Exuberance at City Hall: Local Government Resilience during Housing Booms and Busts,” is funded by the John D. and Catherine T. MacArthur Foundation. The foundation is in its fifth and final year of a $25 million series of grants dedicated to identifying how housing matters to families and communities.

Although the study will look at housing across the country, and will include […]
