In Minnesota, US, the most common measure for snow management performance is the time it takes to completely clear a roadway after a snow event ends. Currently, the Minnesota Department of Transportation (MnDOT) relies on visual inspections by its field crews to estimate this bare pavement recovery time. To help MnDOT more accurately and reliably estimate the performance of its snow management activities, researchers from the University of Minnesota Duluth (UMD) have developed a prototype process that uses

Austria’s Federal State of Niederösterreich has been successfully using Gewi’s TIC software solution to create and distribute information on winter road conditions and work zones for the state’s14,000 kilometre road network. During the winter season, each of the fifty-eight road maintenance departments reports current road conditions in their district to the TIC system, which creates an overview report on which districts have snowfall, road conditions, the highest/lowest temperature, snow chain requirements

Work to upgrade part of the M62 in West Yorkshire to a managed motorway, the first scheme in the Yorkshire and Humber region, reached a significant milestone when the first overhead electronic signs went live. For the first time, the variable advisory speed limit signs have come into operation between junctions 27 and 28 to allow the UK Highways Agency to calibrate and test the technology required for the new managed motorway, with the signs being switched on and off in response to traffic conditions. Advis

A new road sensor system is set to offer more accurate warnings for slippery surfaces. The TrackIce system, developed by Mowic, is to be installed by road maintenance contractor Peab along a 30 kilometre stretch of highway E4 between Stora Essingen and Södertälje in Sweden. According to Mowic, the TrackIce system is quick to install without the need for cables, enabling it to be installed in remote areas where no power is available. The TrackIce central unit can also handle information from other sensors su

California DOT (Caltrans) is installing electronic message signs in an effort to prevent or reduce congestion on the heavily used Interstate 10. Vehicle detection systems have also been installed on the 133 mile stretch of freeway to monitor traffic. The detection systems monitor speed and traffic volume, processing the data and transmitting it to the freeway message signs to give motorists real-time journey time estimates. "Changeable message signs will allow us to deliver information directly to drivers

Capitalising on its investment in Intelligent Transportation Systems (ITS) technology, New Jersey Department of Transportation (NJDOT) is to install permanent dynamic message signs (DMS) along New Jersey’s interstate highways. The signs display major waypoints, such as intersecting highways or significant roadway features, and indicate how many minutes it will take to reach that waypoint. The DOT has completed the testing phase on fifteen DMS on I-287 and I-195 and is planning further signs on other major
