Illinois investing in smarter highways

Almost 1,000 highway deaths in Illinois in 2013 and some of the worst interstate traffic congestion in the country has prompted the state to launch a US$45 million trial to investigate whether a blend of technologies can make smarter highways which are safer for drivers and less prone to congestion. Traffic engineers are focusing initially on the Edens Expressway and the northern stretch of US Highway 41 and will begin incorporating a mix of existing and new technology during the next two years, an under

Almost 1,000 highway deaths in Illinois in 2013 and some of the worst interstate traffic congestion in the country has prompted the state to launch a US$45 million trial to investigate whether a blend of technologies can make smarter highways which are safer for drivers and less prone to congestion.

Traffic engineers are focusing initially on the Edens Expressway and the northern stretch of US Highway 41 and will begin incorporating a mix of existing and new technology during the next two years, an undertaking that could spread to the entire Chicago-area expressway system.

The technology to be trialled includes travel-time estimates using motorists' Bluetooth devices, bus-on-shoulder service during rush hour and traffic cameras along every interchange  Radar devices to detect wrong-way drivers are also to be trialled; these will alert the driver and other motorists via flashing red lights and also feed information to Illinois DOT (IDOT) and the state police.

To improve traffic flow along US 41, Bluetooth receivers would be installed along a 25-mile section of the highway.  These pick up signals from Bluetooth-enabled devices in passing vehicles and enable traffic engineers to estimate the time taken to travel between various points and determine average travel times.

"We are trying to fix a lot of problems with very cost-efficient solutions that can be introduced relatively soon," IDOT secretary Ann Schneider said.

The various projects are in the preliminary engineering stage and construction will be carried out in phases, probably starting in two years. Schneider says she is hoping to accelerate the schedule. Projects would be extended over time to other expressways in the area.

    TransCore has been selected by Cobb County Department of Transportation, Atlanta, to expand its Scats (Sydney Coordinated Adaptive Traffic System) adaptive traffic signal control technology with an additional 75 intersections, nearly doubling its use of the technology and making it the second largest deployment in the United States. The first phase of 26 intersections in the town centre area are now in operation with the remaining intersections expected to be fully operational by October 2012.

    Congestion on US Interstate highways added over US $9.2 billion in operational costs to the trucking industry in 2013, according to research released by the American Transportation Research Institute (ATRI). ATRI, the trucking industry’s not-for-profit research institute, utilised motor carrier financial data along with billions of anonymous truck GPS data points to calculate congestion delays and costs on each mile of Interstate roadway. Delay totalled over 141 million hours of lost productivity, which equ

    Timothy Compston weighs up the critical elements that keep the wheels of dynamic pricing schemes turning in today's high-occupancy toll (HOT) lanes. In the drive towards smarter tolling it is perhaps not surprising that sophisticated pricing algorithms are being rolled out to better reflect supply and demand on the roadway. This is the case with high-occupancy toll (HOT) lanes which a growing number of DoTs are seeing as a way of smoothing the operation of their existing, and planned, freeway infrastructure
