This is the final section of a three-part series about preventive maintenance for pavements. Written by Alan S. Kercher, P.E., Kercher Engineering, Inc We practice preventive maintenance in our everyday lives and possibly with agency equipment such as dump trucks and backhoes, but when it comes to maintaining our roadways, most agencies will always defer repairs until the pavements have failed, resulting in very expensive repairs. This article will provide some guidance to help an agency make the switch fr

A team of eminent Russian specialists* introduce exciting new information technologies, such as the Internet of Things, and foresee their promising applications in the field of transport infrastructure development. Global economic growth, combined with explosive digital technology proliferation, brings new challenges to the field of transport infrastructure. Technical advances such as Intelligent Transportation Systems (ITS), vehicle to infrastructure interfaces, global positioning, electronic toll collecti

As the world descended on Vancouver for the 2010 Winter Olympics, visitors were able to travel around the city with confidence and intelligence thanks to a landmark project by IRF Member, Delcan

Oliver Carsten, Professor of Transport Safety at the Institute for Transport Studies (ITS) at the University of Leeds, UK, discusses Intelligent Speed Adaptation, looking at its safety potential

GTZ highlights a pioneering scheme illustrating the potential of Bus Rapid Transit systems as a viable approach to alleviate the traffic and social problems faced by large cities worldwide Most major cities worldwide have been characterised by the phenomenon of steadily growing urbanisation accompanied by exponentially increasing numbers of private motorised vehicles. This has led to congested roads and sprawling cities, with commuters having to travel long distances to and from work. Despite huge inves

Tony Marshall, Director at Arup, looks at ways in which the company encourages sustainable mobility.From policy and systems development through to the design and execution of major infrastructure projects, he reviews Arup's global project experiences and research programmes. Space on roads throughout the modern world is decreasing as the volume of cars and road users increases. How can mobility be safeguarded without compromising quality of life or environmental well-being? As engineers, we have a responsib

New trials pave the way for smart road pricing using Global Navigation Satellite Systems (GNSS). In recent years, the concept of road charging has been gaining acceptability among Europe's policymakers.

The Portuguese experience with road safety has proved that planning, development, introduction, and hard work do pay off in the end. Paulo Marques Augusto, president of the National Road Safety Authority (ANSR), explained that in the last 10 years a decrease of over 50% has been achieved in the number of fatalities on the road network despite a continuing growth in traffic demand (there are five million vehicles in Portugal), and a similar reduction in travel time on most of the connections between Lisbon a

Twenty years ago Portugal was bottom of the European league in terms of roads and safety. A series of ambitious plans has seen the country rise to the top. Patrick Smith reports on how this was achieved In Portugal, out of 3,600km of main national roads (IP+IC), some 1,500km of motorways/high-capacity routes are financed under public-private partnership (PPP) agreements. These are tolled either using shadow tolls (these are being phased out) or real tolls, and plans are in hand to make routes multi free-fl

Our series of profiles on winning projects from the 2010 Global Road Achievement (GRAA) Awards continues with the Construction Methodology Category won by Barrier Systems/Utah Department of Transportation With any major road construction project, the disruption of traffic flow is of paramount concern for engineers, workers and travellers, particularly as it relates to increased traffic delays and the safety of those driving through the work zone. In the state of Utah, USA, work was recently completed on

Christophe Nicodème, ERF's Director General, explores a missing link in the road safety chain Road works are an essential part of the work of public administrations and toll operators; aimed at preserving a safe road infrastructure for users, while minimising the disruption caused as a result of unavoidable traffic interventions. Given the essential role of road works, one would assume that well-defined regulations exist at national and European level to determine the best way of conducting them. Yet
