AMERICAN SOCIETY FOR MICROBIOLOGY
In conjunction with other published investigations, this work helps to characterize the “urban microbiome” and, in doing so, adds to our understanding of how these microbial communities are formed, maintained, and transferred. Such studies fall in a critical space between the categories of environmental and human-associated microbial ecology and as such must address the challenges of both. Improved approaches to such studies should include designing studies with rich metadata, including architectural features, human contact, environmental exposure, surface type, and surface material; accounting for a wide range of potential biochemical environments, contaminants, and biomass levels; and involving institutional review boards, city officials, and engineers as appropriate.

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.

MINETA TRANSPORTATION INSTITUTE
Why people choose to travel by private car rather than by public transit is of major concern to transportation planners and transit operators. For some reluctant would-be riders, the answer might be summed up by the words of Yogi Berra when asked why he no longer patronized a popular St. Louis nightspot: “Nobody goes there anymore. It’s too crowded.”

New York City: Subway Station Conditions

Thursday, October 9th, 2014
Structural components and architectural components

OFFICE OF THE NEW YORK STATE COMPTROLLER
The New York City subway system includes 468 passenger stations, which are used by 5.5 million riders each weekday. The system is operated by New York City Transit (NYCT), the largest subsidiary of the Metropolitan Transportation Authority. Over the past 32 years, NYCT has renovated 241 subway stations at a cost of $4.5 billion as part of its station rehabilitation programs. Under these programs, each station was fully renovated to a state of good repair, including structural and architectural components. Once the work was completed, however, NYCT moved on to the next station for rehabilitation without committing the resources to maintain the renovated stations.
