As part of a wider Hertfordshire County Council strategy to ease congestion across the county, the council is installing variable message signs to provide live incident information, managed by a centralised control centre at County Hall. The centre opened in October last year at a cost of around US$600,000 and is operated by eighteen staff, who monitor the county’s road network. If an accident occurs, traffic signals can be adjusted and messages displayed in a bid to redirect traffic ease congestion. Mainte

Thousands of UK motorists caught speeding on two stretches of the M62 in Warwickshire could have their convictions overturned because the wrong font was used on the speed limit signs. The Crown Prosecution Service said the signs showed miles per hour (mph) numbers taller and narrower than they should have been, failing to comply with traffic regulations. The regulations governing variable speed limit signs are set out in a government document called Traffic Signs Regulations and General Directions 2002. If

Abu Dhabi traffic police are to introduce an electronic weather system to alert motorists of fog, rain, and visibility problems ahead. Dense fog is a major problem for motorists across the country in the winter months. Heavy dust storms in summer also affect visibility. The system uses the latest technology and combines the tracking systems, patrols distribution information, traffic accident analysis system, and smart traffic awareness system of the Smart Traffic System Centre at the Abu Dhabi Police and T

The second stage of the EC’s HeERO project, which aims to address some of the issues surrounding the eCall system, has just got underway. Jason Barnes reports.

Internet-connected cars are poised to flood the market in the near future. Pete Goldin considers the functionality they offer, the technology they use and the challenge they represent in terms of driver safety.

The era of the digital vehicle, it seems, has started. “We clearly see that cars in the near f

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
