Letty Aarts, senior researcher, SWOV institute for road safety research, the Netherlands, discusses how road design can act as a primary aid to speed enforcement

From an enforcement perspective at least, Toyota's recent recalls over problems with accelerator pedal assemblies had a positive outcome in that for the first time a major motor manufacturer outside of the US acknowledged publicly what many have known or suspected for quite a while: that the capability exists within certain car companies to extract data from a vehicle onboard unit which can be used to help ascertain, if not prove outright, just what was happening in the vital seconds up to an accident or cr

Chris Gibbard and Paul Drummond of Transport Direct on developments in Great Britain in the electronic transfer of bus service data. Great Britain has a dynamic bus market which permits a bus operator to initiate or alter commercial routes by giving a minimum of eight weeks' notice to a registrar (the Traffic Commissioner). A Local Transport Authority (LTA) neither specifies nor determines such services. In addition to commercial bus routes, an LTA will tender and contract for the operation of those additio

A vast array of new products and systems for aiding road safety were displayed at the ITS World Congress in October. David Crawford assesses a selection of safety initiatives exhibited in Orlando. Vital roles for ITS applications in road traffic safety emerge clearly from a new report from the US Transportation Safety Advancement Group. The report has been carried out for the Next Generation 911 What's Next Forum, which is preparing the way for future development of the US national 911 emergency single call

Wisconsin's four-year HOT lanes pilot project, launched in May 2008, cost US$18.8 million to construct. Halfway into the project, which uses variably priced, or dynamic, tolling to improve highway efficiency, the benefits are mounting. The problem was obvious, and frustrating, to anyone who ever sat in bumper-to-bumper traffic on State Route 167 and watched a lone car whiz by every 20 seconds or so in the carpool lane. But for planners at the Washington State Department of Transportation, the conundrum was

Last year, the County of Lancashire, in the north-west of England, repaired a total of 15,000 potholes on its network of roads. In 2010, that number is likely to significantly increase as Lancashire, along with local authorities throughout the UK, deals with the after-effects of a record cold spell in December and January with prolonged snow, ice and sub-zero temperatures.

Telematics Technology's Peter Billington describes the effort to give English local authorities and police forces a UTMC ANPR open communication protocol. The story of the impact of communication protocols on the development and utilisation of intelligent equipment is a familiar one both inside and outside the ITS industry. At the outset, a company pioneering its latest technology invariably develops a proprietary protocol. This enables the company's products to talk to the customer systems which need to a

Traffic flow has been improved, congestion eased and safety increased - by a system of 'stepped speed limits' introduced to UK roadworks. URS Scott Wilson principal consultant Jamie Uff reports

The County of Los Angeles is widely known for having among the worst traffic problems and the most road congestion in the US. To combat these problems, the Los Angeles County Department of Public Works decided to deploy a wireless communications system to connect over 1,000 of the most congested intersections so they could dynamically monitor and manage the congestion and reduce commute times.

Jean Harito, Attica Tollway Operations Authority and Steve Morello, Egis Projects describe how looking to exceed contractual obligations makes good operational and business sense. The Attica Tollway is a modern, 65km, access-controlled urban motorway with three lanes in each direction. It constitutes the ring road around the extensive metropolitan area of the Greek capital, Athens, and forms the backbone of the entire road network in the Attica region. By ensuring freeflow operating conditions, the Attica T

Michael J. Davis of PBS&J looks at the positive effect that open road tolling can have on safety

Transportation agencies and governments are using ITS technology to protect critical infrastructure from terrorist attack and other threats to economic security and public safety. Andrew Bardin Williams reports. It is no secret that we live in a potentially dangerous world. Terrorism as seen on 9/11 in the United States, subsequent attacks in London, Moscow and Madrid and other acts of violence across the developing world have made vigilance the watchword for ensuring security. Key infrastructure is now bei

Machine vision systems offer great variety of function and performance. Teledyne DALSA product manager Manuel Romero describes 10 key criteria to aid selection of advanced camera technology for safety or security applications. There are many ways in which machine vision systems can enhance safety and security in transportation, but the ultimate results will only be as good as the image produced. Success relies on correct selection of the camera of such systems, as the features and performance required vary

The announcement that, in 2012/13, work to extend Managed Motorways to Junctions 5-8 of the M6 near Birmingham in the West Midlands is scheduled to start marks the next step for the UK's hard shoulder running concept, first introduced on the M42 in 2006. The M6 scheme is in fact one of several announced; over the next few years work will start on applying Managed Motorways to various sections of the M1, M25 London Orbital, M60 and M62. According to Paul Unwin, senior project manager with the Highways Agency

Janet Banner, Metropolitan Transportation Commission, and Christopher Hill, Mixon Hill, Inc., outline efforts to explore the use of IntelliDrive technologies in HOT lane applications. On 21 October last year more than 100 transportation professionals came together for a workshop, either in person or via a webinar, to discuss the potential role of IntelliDriveSM technologies in enhancing the operations of High-Occupancy Toll (HOT) lanes. The discussions focused on a White Paper, commissioned by the Metropoli
