An ITIF report published at the beginning of this year stated that America is falling behind other developed nations in terms of ITS technologies and their deployment to address safety, congestion and environmental challenges. The report asked for a stronger commitment from the US federal government (see 'Just crawling along', interview with senior ITIF analyst Stephen Ezell, ITS International March-April 2010, pp.NA1-NA2) in order to address what it sees as increasing disparities with other countries. The

With the Idris system now validated as a speed verification tool, the way is open for loops to be used in more complex enforcement applications. Diamond Consulting Services (DCS), developer of the Idris inductive loop-based vehicle detection and classification system, has recently successfully conducted validation trials which, the company says, open the way for Idris to be used for speed verification and loop-based sensors to be used for more complex applications such as speed-on-green and differential spe

The automated road safety enforcement industry in the United States had a very robust 2010. The industry continued to grow to the point that providers now have nearly 5,000 cameras deployed in 25 of the 50 states and the District of Columbia, with more than 650 communities utilising such life-saving technology. Intersection safety cameras are the most common application but more communities are also implementing road safety camera programmes to deter excessive speeding. Deploying cameras to protect children

For major road works schemes, necessary lane closures are timed to minimise congestion, most frequently at night and on weekends when traffic is at its lightest. As a result, rigid timetables are used in planning, programming and implementing work. In the UK, to calculate the expected traffic demand through roads works, historic profiles from the loop-based MIDAS (Motorway Incident Detection Automatic Signalling) system were used. These provided a valuable indicator of anticipated traffic behaviour but were

Continuing developments in telecommunications and public expectation have left the US's legacy, analogue 911 emergency call system trailing. Linda D. Dodge, Public Safety Program Manager for the ITS programme in USDOT's Research and Innovative Technology Administration, the sponsor of the Next Generation 911 initiative, writes about efforts towards updating

Although much of the emphasis of research into intersection management has tended to concentrate on the needs of urban locations, there remain specific issues pertaining to rural intersections which need to be addressed. Here, Rebecca Szymkowski and Greg Helgeson, Wisconsin DOT, Todd Szymkowski, University of Wisconsin-Madison, and Craig Shankwitz and Arvind Menon, University of Minnesota detail progress on an intersection collision avoidance system for more remote locations.
