INFRASTRUCTURES / SMART ROADS * USA

* Ohio - Speed sensors to help motorists plan travel routes

(Photo by Michael Neilson/The Daily Jeffersonian: The Ohio Department of Transportation is using information collected by speed sensors installed along the state's major interstate highways to help motorists and ODOT personnel monitor traffic conditions. Speed data is collected by sensors such as this one on Interstate 77 in Guernsey County every minute and then sent to BuckeyeTraffic.org.)
Columbus,OH,USA -The Daily Jeffersonian, by Rick Stillion -February 26, 2012: -- Motorists traveling through Ohio have another tool to help them traverse some of the state's highway system in a timely manner...  Speed sensors are being installed as part of the Ohio Department of Transportation's Freeway Management System to help motorists better plan their travel routes... The sensor installations at two-mile intervals on Interstate 70 are expected to be completed by the summer, covering both eastbound and westbound traffic...  The sensors will span the state from the Indiana state line to the West Virginia state line collecting speed data every minute that is sent to BuckeyeTraffic.org -- the state's premier traffic website...  An average of 50,000 vehicles travel daily on I-70 between Columbus and West Virginia, according to ODOT statistics...  The information collected by ODOT also helps determine how quickly traffic returns to normal speeds following weather-related incidents and accidents...

Smart Roads * USA - Testing Ones To Streamline the Commute

Union City,CAL,USA -KCBS -15 Dec 2009: -- The city streets and freeways of the future will be able to tell commuters ahead of time whether they’re about to hit a back-up, and adjust speed limits for optimum traffic flow... That future is already here in Alameda County where traffic lights know to stay green when buses and emergency vehicles are coming... Soon a 20-mile corridor on Interstate 80 between Crockett and Emeryville will experiment with a variable speed limit determined by the road sensors that already calculate driving times... The guiding idea behind the vision Fay and others brainstormed for Bay Area freeways of the 21st century was to give people information about what’s ahead of them no matter how they choose to travel. BART parking lots for example could advise motorists whether they were already full... (Photo: Congested Bay Area freeway. Testing Smart Roads To Streamline the Commute)

‘Smart Road’ Projects * USA - States Creating Ones with Stimulus Funds to Reduce Traffic

Washington,DC,USA -Transport Topics, by Michele Fuetsch -8 June 2009: -- Instead of buying only asphalt and steel, several states will spend federal stimulus dollars on “smart road” projects that use information technology to reduce congestion, according to a survey by the National Conference of State Legislatures.

* Colorado, for instance, plans to spend some of its stimulus dollars on high-tech weather alert systems along Interstate 70 where snow and ice can imperil winter truck traffic through the Rocky Mountains.

* Ohio will spend $15 million in the Cleveland and Akron areas to buy such equipment as traffic cameras, electronic message boards and weather advisory radios.

* Pennsylvania transportation officials said they hope to reduce traffic delays and the resulting pollution from idling by adding 59 closed-circuit video cameras and 39 electronic traffic signs to the roads.

* Virginia, for example, did not allocate any stimulus dollars to ITS, said secretary of transportation, Pierce Homer, have a long lead time and, because the stimulus money must be spent quickly to generate jobs, Virginia concentrated its spending on replacement, not new projects, so hiring would start as soon as possible...
