Road authorities and safety specialists worldwide recognise that the most dangerous part of a longitudinal barrier is the end. A crashworthy end treatment must be able to act both as a redirecting anchor and an impact cushion to errant motorists. The highway safety community has responded to this engineering challenge through continuous investment in innovation over the past 50 years. The resulting “crashworthy” terminals commercially available today reduce the deceleration and avoid ramping, rolling or pit

Join the Premier Event for Road Professionals in 2013 Since 1952, 16 IRF World Meetings have set new standards of excellence for the road industry by connecting industry leaders and experts from across the globe, and enhanced IRF’s image as the leading road development platform.Riyadh, the capital of the Kingdom of Saudi Arabia and the heart of one of the world's fastest growing regions supported by unmatched infrastructure investment programs, welcomes the opportunity to host the 17th World Meeting of the

Engineering firm Exergia completes vital communication route using innovative construction methodology. The devastation caused by a 35-year armed conflict has led to a high state of degradation of Angola’s network of roads and bridges, presenting a significant impediment to the country’s recovery. In 2002, the Government of Angola created an extensive rehabilitation and reconstruction program of the road system. As part of this program, the rehabilitation of National Highway 120, the main road linking

As introduced in an important new publication, the United Nations Economic Commission for Europe (UNECE) has a longstanding commitment to promoting and creating an enabling environment for Intelligent Transport Systems (ITS). The world’s citizens depend on safe, efficient and secure transport systems. Whether we travel by road, boat, rail or air, we rely on our transportation systems to get us where we need to go. The same systems play an important role in our national economic well-being, making it poss

Urban mobility is high on the infrastructure agenda in Mexico. Business News Americas spoke with Salvador Herrera, executive director of the Centre for Sustainable Transport (CTS), about the elements of a sustainable transport system and Mexico City's addiction to the car At the heart of Mexico City's transport policy is a contradiction that is typical of the country as a whole. The government is spending big on Line 12 of the metro system and has introduced the first Metrobús bus rapid transit (BRT) l

A combination of engine and driveline technologies will reduce fuel consumption and increase performance in new generation, low emission machines A wide array of new engine and driveline technologies being developed will help reduce emissions and fuel consumption, while increasing performance in the latest machines coming to market. With engine manufacturers focussing on the Tier 4 Interim/ Stage IIIB and following Tier 4 Final/Stage IV emissions requirements for North America and Europe, sophisticated

A massive construction project has been underway deep in the heart of the Schnecktal valley area in Germany. From the surface, though, you would never be able to tell. The majority of the work is underground, as a joint-venture team led by German contractor Wayss and Freytag Ingenieurbau builds the nearly 7km long Finne Tunnel. After a few years of tunnel boring operations, the contractor is at work finishing the interior of the tunnel, slipforming first the tunnel’s floor and then a walkway with its GOMACO

New technologies are coming to market with regard to driving and supporting tunnels, with drilling and blasting and accompanying shotcreating technologies being widely used worldwide. Drilling and blasting can be a cost-effective method in the right conditions and in this segment Atlas Copco and Sandvik hold major market shares worldwide, although other firms such as Furukawa and Montabert also compete. Shotcreting equipment is widely used following after drilling and blasting, with CIFA broadening its rang

Infrastructure investment means that the road tunnel construction sector is healthy due to demand for new links – Mike Woof reports With many emergent nations investing heavily in infrastructure, the tunnelling sector is seeing extensive business at present. Tunnels provide key links in mountainous areas or in congested cities where building roads on the surface may not be practical. In Asia and Latin America, many key road connections are now being built underground to pass challenging terrain or provide
