TRANSITCENTER
When do people choose transit, and in what conditions? We answer these critical questions by examining how people use transit, using information gathered from a survey of 3,000 people who ride transit in 17 regions and through focus-group discussions with riders in three cities.

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.

CENTER CITY DISTRICT
Transit is not just a convenience; it is essential to the density that enables Center City to provide 42% of all jobs in Philadelphia. If downtown workers relied on cars to the same degree as commuters across the region, then 295,000 workers would arrive each day in 227,150 cars. At 330 square feet per parking space, we would need a giant, surface parking lot of 2.6 square miles – larger than William Penn’s original plan for the city (2.2 square miles river to river, Vine to South) – leaving little room for the office buildings, hotels, hospitals, universities, residences, cultural institutions, historic destinations, restaurants, retail shops and parks that define the diversity and create employment opportunities downtown.
TRANSPORTATION FOR AMERICA
Cities and regions around the country face important choices about how and where they want to grow, how to connect people to economic prosperity and how to use limited resources to promote healthy communities and provide a great quality of life for all of their residents.
Heidi Goedhart, UDOT’s Active Transportation Manager, helps us understand what “Active Transportation” means to Utah. She talks about UDOT’s programs to keep cyclists and pedestrians safe on Utah roads, and also discusses what we are doing to promote safety in alternative modes of transportation. Road Respect and Head’s Up are two of the programs Heidi discusses.

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.
The East Side Access project will link the Long Island Railroad to New York City’s Grand Central Terminal. Projected to be completed in 2022, it required construction of about eight miles’ worth of tunneling in Manhattan and Queens.
