National Transportation Noise Map shows that almost all U.S. residents—97 percent—hear background noise from highways and planes overhead at a safe 50 decibels, about equal to a humming refrigerator. A small fraction of citizens, though, hear noise equivalent to a garbage truck every day. Less than one-tenth of one percent of U.S. residents (approximately 223,000 people) hear 80 or more decibels on a regular basis. Sustained exposure to 85 or more decibels—heavy city traffic—can cause permanent hearing loss over time. In the New York metro area, pictured above, residents living near the region's airports or under flight paths are at greatest risk for unhealthy noise exposure. The U.S. DOT's Bureau of Transportation Statistics (BTS) compiled and analyzed data for the Noise Map, which is meant to help agencies track transit-related noise at the state and local levels. Officials can use the information to implement policies that reduce transit noise. The layers, which now include data up to 2014, will be updated annually and may eventually include noise data from rail and ships. The Noise Map is part of the U.S. DOT's National Transportation Atlas Database (NTAD), a collection of publicly-available infrastructure data.The

The United States Department of Transportation (DOT) is pouring money into transit research at universities nationwide, among them the University of Texas at Austin School of Architecture (UTSOA). The federal agency is giving millions in grant money to UTSOA and its partner schools to fund transit research in so-called megaregions, rural-to-urban geographic areas that share environmental features, infrastructure, and economic futures. The funds will be disbursed over five years, beginning with a $1.4 million grant for UTSOA's 2016-17 fiscal year. Dr. Ming Zhang, associate professor of community and regional planning at the School of Architecture and researcher at the university's Center for Transportation Research will lead the four-school "CM-2" consortium (CM-2 stands for Cooperative Mobility for Competitive Megaregions). The group includes researchers from Louisiana State University, Texas Southern University, and the University of Pennsylvania. “Support from the U.S. Department of Transportation will allow us to advance our research, education, and technology transfer initiatives that work to improve the mobility of people and goods in urban and rural communities of megaregions like the Texas Triangle,” said Dr. Zhang, in a statement. “CM-2 seeks innovations in institutional cooperation for transportation planning, multi-modal integration for increased access and equity, and better transportation investment decisions and public engagement achieved through improved information technologies.” UTSOA's DOT grant is one of 32 from the agency that fund research at University Transportation Centers (UTC) programs. UTC works with transportation agencies and the private sector to study the field from all angles. CM-2 will lead workforce development and education, carry out mobility research, as well as investigate how technology could be used to enhance mobility and economic vitality in megaregions across the United States. The group's research will focus on transportation policy and regional planning, increasing equitable connections across regions, thinking about modeling for fast-growing regions, and coming up with new multi-modal planning strategies.
You can do a lot in fifteen minutes: cook some surf-and-turf, blast through paperwork, star in a mediocre crime drama, or travel 40 miles between major East Coast cities. Well, not yet. Given the excruciatingly slow pace of infrastructure modernization in the U.S., there will be a wait on that last one, probably for decades. Yet, the U.S. is taking small steps towards twenty-first century transportation. Last week, the U.S. Transportation Department granted $27.8 million in Federal Railroad Administration funds to the Maryland Department of Transportation and the Maryland Economic Development Corporation to conduct feasibility studies for a maglev train line that will run between DC and Baltimore. https://www.flickr.com/photos/geoffwhalan/16578045553/in/photolist-6ZNtXq-bkjuSb-byeyp6-qdzcUH-u8F6rc-9DN21-byeq9i-bkjwuj-7sUSTT-4TEqye-qZoBxP-78WXSR-7ya8wK-rfWPnB-7sYQD7-7sYQLS-ziKfWR-6pTxyU-4SpKK-21THR5-4jpRM-Ab3VT-aans1n-aansdz As the above video illustrates, Maglev trains move very, very fast, reaching speeds up to 375 miles per hour. If built, the DC-Baltimore maglev train would be a 40 mile demonstration project to determine how to best bring maglev trains to the United States. Overall, the track will cost an estimated $10 billion to build. Japanese transportation companies and the Japanese government are keen on spreading their products and expertise to the United States, a potentially lucrative market. This spring, Governor Larry Hogan and Maryland Transportation Secretary Pete K. Rahn rode on the Yamanashi Maglev Test Track. The Japanese government has committed $5 billion to the project, and the train operator, the Central Japan Railway Company, will not levy licensing fees for the technology. Stateside, The Northeast Maglev, a private investment group, will also contribute to the project. For those who can't delay gratification, ferroequinologists the world over love to share their love for ultrafast trains.
As of October 27th, the Bronx River Greenway is one mile closer to completion. The United States Department of Transportation awarded a $10 million TIGER grant to the city to build three bridges and a three-quarter mile path connecting the South Bronx's Concrete Plant Park with nearby Starlight Park. Though modest in scale, the grant adds momentum to the decades-long movement to green one of the most industrial areas in the borough. Two of the bridges will be built over the Bronx River—one near Westchester Avenues and the other adjacent to 172nd Street. The third bridge will be laid over Amtrak rail lines at East 172nd Street. When this critical link is complete, cyclists and pedestrians will be able to enjoy 1.8 miles of trails along the river, from East 177th Street to Bruckner Boulevard. Currently, recreation-seeking Bronxites who wish to travel between the two parks face a daunting and dangerous trek across a Sheridan Expressway access ramp. The New York State Department of Transportation committed funds to the project in 2008, but the DOT had to negotiate usage rights with Amtrak. The Acela runs adjacent to the Bronx River, in between the two parks. In total, the project is estimated to cost between $29 and $32 million. Federal, state, and local governments, as well as nonprofits, have pledged $12 million towards the project, in addition to the TIGER grant. Still, there is $7 to $10 million dollar funding gap for the project. Construction will begin June 2016 and be complete by 2020.
Chicago's long-awaited bikeway and elevated park, The 606, opened last weekend (on 6/6, no less) to a rush of pedestrians and cyclists who were eager to test out the new 2.7-mile trail after years of planning, design and construction. The public park remains extremely popular in the sunny week following its debut. https://vimeo.com/130217662 Formerly called the Bloomingdale Trail, the former railroad has been likened to New York City's High Line, but it is quite different—the 606 is as much a highway for bikes as anything else, due in part to its having been largely funded through the U.S. Department of Transportation's Congestion Mitigation and Air Quality (CMAQ) improvement program. For those who haven't had a chance to visit the trail, Steven Vance of Streetsblog snapped this time-lapse video of a recent bike ride that covers the length of the trail, which runs through the West Side neighborhoods of Humboldt Park, Logan Square, Wicker Park, and West Town. (Vance is also a contributor to AN.) https://instagram.com/p/3tlNEuERTh/ Michael Van Valkenburgh Associates led the design of the trail, which slopes slightly at various points throughout its length to slow bike traffic and suggest spaces for community events. Several access points connect the elevated trail to parks and city streets below. Meanwhile with The 606 up and running, affordable housing advocates are worried the popular park could help swell the tide of gentrification sweeping out longtime neighborhood residents. https://instagram.com/p/3t4zaOCP0J/
Chicago’s plan to extend and revamp its downtown riverwalk got a major shot in the arm from the feds last week. U.S. Dept of Transportation Secretary Ray LaHood announced the federal government will loan the city $99 million under the Transportation Finance Innovation Act, a program geared at transportation projects of “national and regional significance.” Mayor Rahm Emanuel had previously set his sights on just such funding, as well as financial sponsors for ongoing maintenance. The project, which is scheduled to be finished by 2016, hopes to draw more attention to the riverfront. Designs by Sasaki Associates, Alfred Benesch & Co., Ross Barney Architects, and Jacobs/Ryan Associates call for six unique identities across six downtown blocks of the Chicago River, such as The Jetty, The Cove, and The River Theater. Read more about the design in AN's previous report.
