Social media have become an essential source of information before, during, and after disasters. Social networks like Twitter, Facebook, and Tumblr—instantaneous, far-reaching, and interactive— have become the convergence point for a range of information sources, dialogues, and dynamic content. A survey conducted by the New York University (NYU) Rudin Center for Transportation Policy and Management found that during Superstorm Sandy, social media were the second-highest-rated source of information, ranking higher than other popular sources such as television and radio news, news websites, and community groups.

Residential Street Parking and Car Ownership

Residential Street Parking and Car Ownership

Problem, research strategy, and findings: Local governments’ minimum street-width standards may force developers to oversupply, and residents to pay excessively for, on-street parking in residential neighborhoods. Such oversupply is often presumed to both encourage car ownership and reduce housing affordability, although little useful evidence exists either way. This article examines the impact of street-parking supply on the car ownership of households with off-street parking in the New York City area.

The off- and on-street parking supply for each household was measured through Google Street View and Bing Maps. The impact of on-street parking on car ownership levels was then estimated in an innovative multivariate model. The unique set-up of the case study ensures 1) the weak endogeneity between parking supply and car ownership and 2) the low correlation between off-street and on-street parking supply, two major methodological challenges of the study. Results show that free residential street parking increases private car ownership by nearly 9%; that is, the availability of free street parking explains 1 out of 11 cars owned by households with off-street parking.

Takeaway for practice: These results offer support for community street standards that make on-street parking supply optional. They also suggest the merits of leaving the decisions of whether, and how many, on-street parking spaces to provide in new residential developments to private markets rather than regulations.

Research support: This project was supported by grants from the University Transportation Research Center (Region 2) and the Wagner School Faculty Research Fund.

How New York Housing Policies Are Different -- and Maybe Why

Almost everyone says New York City is exceptional, and many people think that housing is one of the most exceptional aspects of New York life. But New York’s housing conditions are not so different from those in other large US cities, or at least not in the ways that are commonly believed. Policies, not conditions, are what truly set New York’s housing market apart.  Our aim in this chapter is to describe New York City’s policies, to explore how and why they differ from those in Los Angeles and other large cities, and whether they have shaped how New York City’s housing market has weathered the recent downturn. The policies we consider are public housing, in rem properties, other subsidized housing, rent regulation, housing allowances, city capital subsidies for construction and rehabilitation, special needs housing, local tax structures, and building codes. Do unusual housing market conditions lead to these unusual policies? Do some common factors cause both unusual policies and conditions? Naturally, we cannot answer these questions definitively. But we can offer some alternative explanations.

Overweight, obesity, and inactivity and urban design in rapidly growing Chinese cities

Overweight, obesity, and inactivity and urban design in rapidly growing Chinese cities

China faces rising rates of overweight, obesity, and physical inactivity among its citizens. Risk is highest in China’s rapidly growing cities and urban populations. Current urban development practices and policies in China heighten this risk. These include policies that support decentralization in land use planning; practices of neighborhood gating; and policies and practices tied to motor vehicle travel, transit planning, and bicycle and pedestrian infrastructure. In this paper, we review cultural, political, and economic issues that influence overweight, obesity, and inactivity in China. We examine key urban planning features and policies that shape urban environments that may compromise physical activity as part of everyday life, including walking and bicycling. We review the empirical research to identify planning and design strategies that support physical activity in other high-density cities in developing and developed countries. Finally, we identify successful strategies to increase physical activity in another growing, high-density city – New York City – to suggest strategies that may have relevance for rapidly urbanizing Chinese cities.

How Social Media Moves New York, Part 2: Recommended Social Media Policy for Transportation Providers

How Social Media Moves New York, Part 2: Recommended Social Media Policy for Transportation Providers

Social media networks allow transportation providers to reach large numbers of people simultaneously and without a fee, essential factors for the millions of commuters and leisure travelers moving through the New York region every day. This report, based on earlier findings (from Part 1), which analyzed local transportation providers’ use of social media, and a seminar on the subject in the wake of Hurricane Sandy, recommends social media policies for transportation providers seeking to inform, engage and motivate their customers.

The goals of social media in transportation are to inform (alert riders of a situation), motivate (to opt for an alternate route), and engage (amplify the message to their friends and neighbors). To accomplish these goals, transportation providers should be:

- Accessible: Easily discovered through multiple channels and targeted information campaigns

- Informative: Disseminating service information at rush hour and with longer-form discussions on blogs as needed

- Engaging: Responding directly to customers, marketing new services, and building community

- Responsive: Soliciting and internalizing feedback and self-evaluating in a continuous cycle

Urban Mobility in the 21st Century

Between 2010 and 2050, the number of people living in the world’s urban areas is expected to grow by 80 percent – from 3.5 billion to 6.3 billion. This growth will pose great challenges for urban mobility – for the networks of transportation facilities and services that maintain the flow of people and commerce into, out of and within the world’s cities.

Addressing the challenge of urban mobility is essential – for maintaining cities’ historic role as the world’s principal sources of innovation and economic growth, for improving the quality of life in urban areas and for mitigating the impact of climate change. It will require creative applications of new technologies, changes in the way transportation services are organized and delivered, and innovations in urban planning and design.

This report examines several aspects of the challenge of urban mobility in the twenty-first century – the growth of the world’s urban population, and changes in the characteristics of that population; emerging patterns of urban mobility; and changes in technology design and connectivity.

 

 

Transportation During and After Hurricane Sandy

Transportation During and After Hurricane Sandy

Hurricane Sandy demonstrated the strengths and limits of the transportation infrastructure in New York City and the surrounding region. As a result of the timely and thorough preparations by New York City and the MTA, along with the actions of city residents and emergency workers to evacuate and adapt, the storm wrought far fewer casualties than might have occurred otherwise.

This report evaluates storm preparation and response by New York City and the MTA, discusses New Yorkers' ingenuity in work continuity, and recommends infrastructure and policy improvements.

Commuting to Manhattan, A study of residence location trends for Manhattan workers from 2002 to 2009

Manhattan, a global center of  finance, culture, fashion and media, harnesses a workforce of 2 million people. Regionally, Manhattan is the business hub for the New York metropolitan area, with commuters entering the city every morning from the other four boroughs,  suburban counties in New Jersey, the Hudson Valley, western Connecticut, and Long Island, and distant locations, such as eastern Pennsylvania. The workforce of Manhattan is both growing and changing. There is a growing set of high-income, service-related occupations, and an increasing number of workers are residing in the outer boroughs or to the west, across the Hudson River in New Jersey. In fact, Manhattan now has 59,000 “super-commuters” who do not live within the metropolitan region. This report examines key trends in the residential location of Manhattan workers and will also discuss the travel, occupation, and income characteristics of Manhattan workers living in the surrounding metropolitan region. Finally, we explore the strength, resilience and vitality of Manhattan as a global economic and cultural hub in the 21st century.

The Greatest Grid: The Master Plan of Manhattan, 1811-2011

The Greatest Grid: The Master Plan of Manhattan, 1811-2011

Laying out Manhattan's street grid and providing a rationale for the growth of New York was the city's first great civic enterprise, not to mention a brazenly ambitious project and major milestone in the history of city planning. The grid created the physical conditions for business and society to flourish and embodied the drive and discipline for which the city would come to be known. Published to coincide with an exhibition at the Museum of the City of New York celebrating the bicentennial of the Commissioners' 1811 Plan of Manhattan, this volume does more than memorialize such a visionary effort, it serves as an enduring reference full of rare images and information.

The Greatest Grid shares the history of the Commissioners' plan, incorporating archival photos and illustrations, primary documents and testimony, and magnificent maps with essential analysis. The text, written by leading historians of New York City, follows the grid's initial design, implementation, and evolution, and then speaks to its enduring influence. A foldout map, accompanied by explanatory notes, reproduces the Commissioners' original plan, and additional maps and prints chart the city's pre-1811 irregular growth patterns and local precedent for the grid's design. Constituting the first sustained examination of this subject, this text describes the social, political, and intellectual figures who were instrumental in remaking early New York, not in the image of old Europe but as a reflection of other American cities and a distinct New World sensibility. The grid reaffirmed old hierarchies while creating new opportunities for power and advancement, giving rise to the multicultural, highly networked landscape New Yorkers thrive in today.

 

More than Just Exercise: Walking in Today's Cities

More than Just Exercise: Walking in Today's Cities
August, 2011

Transportation planners, policymakers, urban designers, and activists have expended considerable effort over the past few decades promoting walking as one of several alternatives to driving.  More recently, the public health benefit of a physically active population, including a population that walks more often, has become another reason to encourage walking.  Amongst all of this excitement about walking, there has so far been little exploration of the role walking plays in people’s lives and cities’ welfare.  One little understood aspect of walking is its appeal beyond simple “derived demand” travel choice frameworks.  Though we might intuitively know that people walk for more than just to get from A to B, there’s been little to explain what people gain from walking beyond its potential health benefit.  An investigation of pedestrian behavior using the 2009 National Household Travel Survey suggests that the reasons that people choose to walk vary considerably across place and class, and that walking in urban areas may best be explained by a dual conceptualization of walking as the mode of last resort and a highly-prized urban amenity.  This seemingly self-contradictory dual role suggests that policies that want to encourage walking across a broad swath of the population will need to overcome barriers rooted in everyday lifestyles just as much as in the quality of the built environment.
