Subways and Urban Growth: Evidence from Earth

Figure 1: Growth of Subway Systems

UNIVERSITY OF TORONTO
BROWN UNIVERSITY
We investigate the relationship between the extent of a city’s subway network and its population, transit ridership and spatial configuration. To accomplish this investigation, for the 632 largest cities in the world we construct panel data describing population, total light, measures of centralization calculated from lights at night data, and the extent of each of the 138 subway systems in these cities. For a subset of these subway cities we also assemble panel data describing bus and subway ridership.

Future of Rail 2050

Wednesday, October 8th, 2014
This graphic depicts countries and territories with 2050 urban populations exceeding 100,000. Circles are scaled in proportion to urban population size.

ARUP
This thought-piece focuses on the passenger and user experience. The journeys imagined here are intended to generate a conversation about the future and provide the big picture context for future planning and decision-making by the rail industry and by governments. They are also intended to set out a forward-looking and inspiring vision for rail. With the increasing pace of technological change, perhaps the more imaginative scenarios will come to fruition. The case studies indicate trends taking place in rail. They are early signs of possible directional change, and reveal directions in which the future could be heading. Whether these become more widely implemented remains to be seen.

THE JOURNAL OF TRANSPORT AND LAND USE
In light of the increasing reliance on compact growth as a fundamental strategy for reducing vehicle emissions, it is important to better understand how land use-transportation interactions influence the production of mobile source emissions. To date, research findings have produced mixed conclusions as to whether compact development as a strategy for accommodating urban growth significantly reduces vehicle travel and, by extension, mitigates environmental impacts, particularly in the area of air quality. Using an integrated simulation approach coupled with long-term land development scenarios, we conducted an assessment of the impacts of different long-term primarily residential growth patterns on vehicle travel and pollutant emissions in the eight counties of the San Joaquin Valley region in central California.

AMERICAN PUBLIC TRANSPORTATION ASSOCIATION
Rapid growth in the number of older people in the United States during the coming decades will lead to greatly increased needs for expanded and enhanced public transportation services. This report: a) identifies the range of actions that will be needed to expand mobility options for older people, including accessible public transportation services; b) quantifies the demand for these public transportation services; and c) estimates the funding that will be needed to provide them.

URBAN LAND INSTITUTE
“Infrastructure 2009 warns that short-term stimulus funding for various road, transit, rail, and water projects offers no substitute for a concerted long-range U.S. effort to maintain national prosperity…”

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
