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

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.
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/
