INFRASTRUCTURES * USA - AASHTO calls for big expansion of highway system
Washington,DC,USA -Fleet Owner, by Sean Kilcarr -Apr 27, 2010: -- Via a series of reports detailing the nation’s transportation woes, the American Association of State Highway and Transportation Officials (AASHTO) is pushing to not only rebuild existing infrastructure, but to significantly expand it to keep up with rapidly increasing demand... Horsley told FleetOwner that while there’s been much ado from the Obama administration and the U.S. Department of Transportation (DOT) of late in terms of beefing up investments in national high speed rail and mass transit systems – efforts AASHTO embraces, he stressed – little is being said about highway expansion... The report notes that travel on the U.S. highway system increased five-fold over the past 60 years from 600 billion miles driven to almost three trillion in 2009. It says annual travel is expected to climb to nearly 4.5 trillion miles by 2050 – even with aggressive strategies to cut the rate of growth to only one percent per year... As a result of higher travel volumes coupled with limited roadway capacity, drivers with a 30-minute commute lose 22 hours annually – nearly three full work days – just sitting in traffic...

Mercer Island,Washington,USA -Mercer Island Reporter, by JASON LU -Apr 28 2010: -- Islanders of a certain age will remember the overhead lane signals on the old I-90 bridge and the approaches to it. The signals allowed traffic planners to allot an extra lane during peak commute times. The signals disappeared long ago, but with new technology and increasing traffic congestion, they are here again... This summer, the Washington State Department of Transportation (WSDOT) will begin installing overhead electronic signs on northbound Interstate 5, State Route 520 and Interstate 90 between Seattle and Bellevue. The signs are a key component of the WSDOT Smarter Highways program, which uses real-time traffic information to improve safety and reduce congestion... (Photo from media.pnwlocalnews: Interstate 90 had electronic signs set above each lane to allow for opening or closing the lanes according to traffic flows at peak periods. The signs were abandoned when the bridge was rebuilt and express lanes were added)
