Beginning in the 1990s, Oregon was one of the first US states to use weigh-in-motion scales and transponder-based systems to enable trucks to avoid having to stop at weigh stations. Its Green Light preclearance system soon became a model for similar deployments throughout the country. Today, Green Light annually weighs and screens 1.6 million trucks as they approach 21 Oregon weigh stations and it preclears 1.5 million of them.

Deployment of solar-powered LED road studs has provided significant cost benefits whilst reducing KSIs on notorious routes in South Africa. Can these results be replicated in other regions of the world and on less notorious stretches of road? According to Kevin Adams, Astucia's CEO, they can.

Road traffic accidents have an enormous impact on society in terms of human loss, pain and suffering and a significant cost to the economy, the individual and their families. Accident rates on South Africa's roads are among the highest in the world and cost the country in the region of $163 million each year. The former head of the Department of Transport (DoT), Dr Kwazi Mbanjwa, described the situation as "carnage on our roads", with over 500,000 accidents and 10,000 fatalities per annum and the number of

Scott Andrews and Scott McCormick take a look at how standards development for the telematics environment needs itself to evolve in order to stay abreast of technological advances. While the road has been somewhat arduous, telematics has evolved from a research activity to a resource for fleet operators, consumers and road management authorities.

John C. Toone, King County Metro, describes the transition to an IntelliDrive-led approach to communication and information sharing in line with the introduction of a new bus rapid transit service. King County Metro (KC Metro), which serves Seattle, Bellevue and over 20 suburban towns, has been active in the development of intelligent transportation systems for many years. It has operated a signpost-based AVL system for more than a decade and has used this to provide bus location information to the public o

District 7 of Caltrans has been conducting trials to see whether the use of a single inductive loop to measure vehicle lengths and so identify heavy trucks is feasible. So far, the results have been very promising, according to Lead Transportation Engineer Steve Malkson. Between them, the adjoining ports of Los Angeles and Long Beach, the US's two biggest, cover some 10,700 acres (43km2) and 68 miles (109km) of waterfront.

The use of a Vehicle Data Translator will allow every vehicle on a given segment of road to contribute to a highly accurate, readily accessible source of localised weather information, thus improving safety in all conditions. Sheldon Drobot and William P. Mahoney III, US National Center for Atmospheric Research, Paul A. Pisano, USDOT/Federal Highway Administration, and Benjamin B. McKeever, USDOT/Research and Innovative Technology Administration, write. On the morning of June 10 2009, under the cover of den

Amsterdam City Council has chosen to move away from manual enforcement of its environmental zone, which is intended to keep highly polluting goods vehicles out of the city centre, and is installing an automated, ANPR-based system. The signs are not much to look at: white with a red circle and the all-important word Milieuzone ('Environmental zone'). But these signs mean that Amsterdam's city centre is strictly off-limits to polluting goods traffic. At the moment compliance is monitored by special wardens wh

Andrew Rooke and Dave Marples of Technolution B.V. take a look at what can be done to address a long-standing problem: the all-or-nothing approach of automated enforcement. To start, a brief history of speeding: on 14 November 1896, the first Veteran Car Run was staged in England from London to Brighton. It was organised to celebrate new British legislation to raise the maximum speed of vehicles from four to 14mph while also removing the need for a person waving a red flag to walk in front of the car and wa

Across the board, technology is being brought to bear to improve the efficiency of enforcement. Bus lane monitoring, parking and controlled access have all benefited from systems introduced in recent months. While speed and red light infringements tend to attract the most attention, there remain several other areas of enforcement where automation can bring significant operational and efficiency benefits. Lane monitoring and access control also continue to benefit from technological development.

David Crawford watches the race to get the world's first PRT system up and running. To paraphrase the old joke about buses bunching, you seem to have to wait several decades for a Personal Rapid Transit (PRT) system, and then half a dozen come along together. Currently, in fact, there are well over that number of schemes for driverless electric passenger-carrying 'pod' networks at various stages of planning, design and implementation around the world. Locations range from a straight-off-the-drawing board ne

Econolite's new subsidiary Aegis ITS has been set up to address the increasingly complex and exacting needs of agencies in the ITS sector. Chief Operating Officer Doug Terry talks about the evolution to service solution provider. A few very notable and honourable exceptions notwithstanding, it is these days becoming increasingly rare to find a public agency which develops its own traffic management systems. Indeed, most now rely on specialist manufacturers and suppliers to fulfil their needs. This has the h

Jon Tarleton, Quixote Transportation Technologies, Inc., talks about developments in mobile weather information gathering Quixote Transportation Technologies, Inc. (QTT) is promoting the greater use of mobile technologies to provide infill between fixed Road Weather Information System (RWIS) infrastructure. It is, the company says, a means of reducing the expense of providing comprehensive, network-wide coverage, particularly in geographic locations where the sheer number of centreline miles causes cost to

Tools to support operational decisions in winter maintenance can remove subjectivity and increase efficiency; Vaisala's Danny Johns talks about latest developments Even the presence of trees at the roadside can have an effect on temperature An effective Road Weather Information System (RWIS) network can save a local road authority or jurisdiction tens of thousands of dollars or Euros'-worth of labour and consumables in a single night. Get those winter maintenance operations right over just three or four nig

For many, Ethernet- and IP-based networks are the cast-iron solution to ITS's communications needs. However, there remain issues from manufacturer to manufacturer with interpretation of what are supposed to be common standards The 'promise' of Ethernet was that different devices such as IP video cameras and traffic signals could be easily integrated into communications networks, simplifying the process of transporting data over copper, fibre or wirelessly. However, although Ethernet devices have come to pre
