 In an effort to best utilise funding for dynamic message signs (DMS) scheduled for replacement, 6576 Arizona Department of Transportation (AzDOT) embarked on a pilot DMS retrograde refit upgrade from DMS supplier 7846 SES America (SESA).

Following the pilot on a metropolitan area freeway, AzDOT executed another 20 retrofit upgrades based on the quality and performance of the trial project and after realising that cost-savings would result in excess of US$2 million over the original sign replacement plan on the first phase alone, says SESA.

In addition, SESA provides on-site diagnostic support and adaptation to AzDOT hot climate applications and claims the retrofit signs are notably brighter and 8- per cent more energy-efficient than the existing signs.

AzDOT is also replacing another 23 signs eligible for a retrofit upgrade in the Phoenix metro area and a rural sign retrofit begins in October.

    Arizona DOT to test prototype wrong-way vehicle detection system
    After a comprehensive study of wrong-way driving crashes on state highways and how technology may help reduce the threat, the Arizona Department of Transportation (ADOT) is planning a prototype project to use existing highway sensors to detect wrong-way vehicles and alert authorities and other motorists. ADOT director John Halikowski said the study sets the stage for the agency to develop and test a unique and innovative system to detect and track wrong-way drivers, improving opportunities for law enforceme

    ‘Free’ power for signs, shelters and so much more
    David Crawford looks at the sunny side of the street. Solar power has been relatively slow in entering the transport sector, but a current blossoming of activity bodes well for the large-scale harnessing of an alternative energy that is zero-emission at source and, in practical terms, infinitely renewable. Traffic management and traveller information systems, and actual vehicles, are all emerging as areas for deployment. Meanwhile roads themselves are being viewed as new-style, fossil fuel-free ‘power stati
