Drive C2X has shown that advanced warning of poor road conditions could cut fatalities, as David Crawford explains. Connected vehicle (CV)-based warning technologies could mean 6% fewer deaths and 5% fewer injuries in road traffic accidents in Europe, according to the final results of the European Commission (EC) co-funded DRIVE C2X project. According to the European Centre for Information and Communication Technologies (EICT) which provided management support, these “prove that CV systems work and can hav

Colin Sowman catches up with the latest moves in the 5.9GHz exclusivity debate. The Wi-Fi Innovation Act, recently introduced to both the US Senate and its House of Representatives, moves into a new phase in the debate over the exclusive right of the 5.9GHz band for Vehicle to Vehicle (V2V) communications. If the Act comes into law, it would require the Federal Communications Commission (FCC) to conduct tests across the whole 5GHz band to determine if the spectrum can be shared without interfering with curr

Victoria Banks and Neville Stanton [1] of Southampton University’s Transportation Research Group examine the real impact of creeping driver automation. Safety research suggests that 90% of accidents are thought to be a result of driver inattentiveness to unpredictable or incomplete information and the vision is that highly automated vehicles will lead to accident-free driving in the future.

Tolling may be the way forward for paying for the roads of the future - but where will concessionaires find the money and do they need funding or financing? Increasingly, governments around the world are concluding that they can no longer pay for new roads and are turning to the private sector for help.

David Crawford investigates a promising development to counter the problem of fog in the Gulf States. Despite being a largely desert area with low rainfall, fog is a major driving hazard in countries on the Arabian peninsula, such as the UAE. The fog is the result of moist air moving across from the neighbouring Gulf during the afternoon and evening, and experiencing radiation cooling at night.

Idaho leverages the increased capability and reliability of its road weather sensor network to reduce costs and prevent accidents. Weather-related accidents can form a significant chunk of an authorities’ annual road casualty statistics. While authorities cannot control the weather, the technology exists to monitor the road conditions and react with warnings to motorists and the treatment of icy or snow-covered roads. However, with all capital expenditure now placed under the microscope of public scrutiny,

A mobile road weather sensor is providing authorities with new options for monitoring road conditions and winter maintenance operations. Road and traffic engineers know the vulnerable points in their network – cold spots where ice forms first, high-banked roads where snow accumulates, fog pockets… Traditionally, most authorities will position weather stations at these points to detect and monitor road conditions during bad weather events.

ASECAP debated the impact of the financial crises on Europe’s tolling companies and considered the future in diverse economies. Colin Sowman picks some of the highlights. This year ASECAP (Association Europeenne des Concessionnaires d’Autoroutes et d’Ouvrages a’ Peage, with members in 21 countries managing 46,000km of roadway) held its annual Study & Information Days in Athens, Greece – one of the country hardest hit by recent economic problems. While the theme of the conference, Ensuring Sustainability in

New regulations are set to standardise the process of awarding concessions across the European Union. In the wake of several inconsistent judgements at the European Court of Justice, the European Commission has approved new legislation that defines a concession. The basic demarcation from a public contract remains the same in that concessions include the right to exploit the work or services provided instead of payment. However, at the point of signing, the regulations impose an all-inclusive threshold of €

Canadian researchers Olivier Quirion-Blais, Martin Trépanier and André Langevin have developed an algorithm to determine the most efficient routes for snow ploughs and gritters. Snow plough routing has always been something of a ‘black art’: to direct a fleet of show plough to clear priority roads without having the same road cleared several times while others are left untreated. Increasingly, GPS is being used to track the routes the clearing vehicles have taken but until now it has not been possible to ta

Q-Free’s Frank Kjelsli talks to Colin Sowman about why video tolling could be the boost to efficiency and interoperability the industry is seeking. Like it or not, the principal of one person, one tolling account is likely to become a reality: be that in America with the 2016 interoperability deadline or the European EETS requirement. Multi-tag readers are being introduced and alliances are being formed to meet legislative requirements but as the debate continues about which systems and protocols to adopt,

Arno Klamminger and Wolfgang Fleischer from Kapsch’s ETC Business Unit outline a new back office solution which addresses the ongoing changes in the road user charging sector. The rapidly increasing scale of some Road User Charging (RUC) schemes, both current and proposed, presents systems developers and manufacturers with significant opportunities in terms of product sales. However, it also presents them with significant challenges - and size is but one part – as at regional, national and international lev

David Crawford looks at camera-based vulnerable road users protection systems.Safe and efficient operation of road-based transit depends on minimising the risks of incidents involving other vehicles or vulnerable road users such as pedestrians, cyclists and passengers boarding or alighting from buses or trams. The extent and quality of the visibility available to drivers is crucial in preventing and avoiding incidents. Conventionally, they have had to rely on fairly basic equipment - essentially the human

Caldecott Tunnel’s new Fourth Bore is utilising a bespoke high-capacity monitoring and communications network from Moxa. The Caldecott Tunnel connects Contra Costa and Alameda counties in Northern California and traditionally it has suffered severe congestion - especially during peak hours. Opened in 1937 as a twin-bore arrangement, by 1964 the increase in traffic volumes led to a third bore being added. Shortly after the third bore was opened a tidal flow was introduced with the centre bore alternating in

Interoperable CCTV can provide early warning of problems and help improve traffic management and incident response as Morteza Fahrtash and Carlos Ortiz explain. California’s transportation system is one of the state’s defining features and Caltrans (California Department of Transportation) strives to improving mobility across the state through the design, construction, operation and maintenance of the network of highway, freeways, toll roads and expressways.
