Mitsubishi’s David Jones considers an alternative to purchasing the display technology for traffic management centres. Display screen technology is evolving rapidly but while the video wall is arguably the most important technology system in a traffic management centre (TMC), most are five to 10 years old and effectively obsolete. When faced with similar problems, other sectors around the world have adopted a policy of leasing all or part of the equipment.

Andrew Bardin Williams looks at the City of Phoenix where voters backed a $30bn plan to revamp its transportation network to cultivate a more connected community. According to a Land Use Institute study, half of all Americans and even more millennials (63%) would like to live in a place where they do not need to use a car very often. The City of Phoenix is putting in place plans to revamp its urban development and transportation policies to meet these changing quality of life perceptions.

The connected car concept is predicated on fast and reliable wireless communications in all locations but research has revealed wide variations in connectivity. The performance of wireless communications between two vehicles (V2V) or a vehicle and the infrastructure (V2I) is highly dependent on the environment and any surrounding interacting objects which can attenuate or support the wireless propagation.

Teledyne Dalsa’s Manny Romero looks at how the combination of camera manufacturer and software provider can make enforcement easier. Californian video analytics solution provider Eutecus develops real-time images capture and high speeds processing technology for applications including intelligent lighting and advanced driver assistance systems.

In the wake of the VW scandal John Kendall looks at emissions testing on both sides of the Atlantic. Since the VW emissions story broke in September, emissions testing has come under greater scrutiny, and none more so than in Europe, where critics have long been highlighting the weaknesses of the testing system. Ironically, changes to the emissions testing process were already under review but the story has pushed it up the agenda.

In-vehicle anti-collision systems continue to evolve and could eliminate some incidents altogether. John Kendall rounds up the current developments. A few weeks ago, I watched a driver reverse a car from a parking bay at right angles to the road, straight into a car driving along the road. The accident happened at walking pace, no-one was hurt and both cars had body panels that regain their shape after a low speed shunt.

Advanced driver assistance systems (ADAS) are evolving at a rapid pace – but drivers’ ability to cope with them is not and at some point the mismatch must be addressed. Probably the biggest challenge the transportation industry has ever faced.” That is how Dr Bryan Reimer of Massachusetts Institute of Technology AgeLab describes the challenges posed by semi-autonomous vehicles.

Road crashes are not as random as they may appear and analysing data can reveal patterns that can help various authorities target their resources more accurately. David Crawford reports. Figures from the US National Highway Traffic Safety Administration (NHTSA) show that in 2013 there were 32,719 people killed on American roads and 2.31 million injured. While these form part of an overall 25% drop over the decade from 2004, US Transportation Secretary Anthony Foxx continues to stress that reaching the procl

Emergency vehicle preemption systems can offer benefits to more than just first responders: mass transit and maintenance departments can also benefit from the technology. It is difficult to over-emphasise how critical response times are to the outcomes of medical emergencies or to reduce property loss.

Timothy Compston finds out if exchanging traffic and road condition data with private app developers makes sense for both drivers and road authorities. Much has been said about the potential benefits for authorities in sharing data with traffic and navigation app developers, and receiving ‘crowdsourced’ information in return – so how is it working in practice?

User-based insurance is blazing a trail others would like to follow and is also discovering the challenges. The ITS sector needs to keep a very careful eye on the automotive industry: “There’s a war going on in the connected car space creating richer datasets than we ever imagined possible” says Paul Stacy, research and development director of Wunelli, part of the LexisNexis group. The car makers have gone way beyond infotainment, unlocking huge amounts of data in the process … facts and figures which the i

Road authorities have a lot to gain from high-resolution traffic data, argues Pravin Varaiya. Traffic engineers have traditionally been forced to operate with limited data regarding the performance of their arterials. Traffic studies are often commissioned once every three years, over a few days, to get an updated estimate of utilization.

Xerox’s Passenger Detection System has been trialled in California and compared with the state’s team of human counters giving some interesting results, as Colin Sowman discovers. Like others adopting high-occupancy and high-occupancy vehicle (HOV) lanes for congestion management, Caltrans has faced challenges with compliance in what has been effectively an ‘honour system’ with drivers trusted to set their tags correctly or comply with the multi-passenger requirement.

The type-approval of roadside drug testing equipment could bring about fundamental changes to the way police tackle the problem as Colin Sowman finds out. It has been almost 50 years since the first drink-driving laws were introduced but the problem persists: the European Commission estimates that 25% of road fatalities in the EU are the result of alcohol consumption. Statistics from the UK show that 20% of drivers killed in road accidents in 2012 were over the blood alcohol limit for driving.

David Crawford looks at the latest thinking about calculating the benefits associated with the environmental side of ITS schemes. The penny is dropping that some environmental costs “are being shifted outside the traditional bounds of evaluation methods” for ITS-based road transport projects, according to researchers at the UK University of Leeds’ Institute for Transport Studies.
