First product to undergo Technology Partnerships

A Technology Partnerships study has been announced to evaluate the safety benefits of a solar-powered traffic signage system designed to minimise crashes on horizontal curves in the US. Part of the US FHWA Highways for Life initiative, evaluations will test the effectiveness of innovative road infrastructure safety technologies that are fully developed and market ready, but have had little use on US roads.

Tapco's sequential dynamic curve warning system will be evaluated for two years in several US states
A Technology Partnerships study has been announced to evaluate the safety benefits of a solar-powered traffic signage system designed to minimise crashes on horizontal curves in the US. Part of the US 831 Federal Highway Administration Highways for Life initiative, evaluations will test the effectiveness of innovative road infrastructure safety technologies that are fully developed and market ready, but have had little use on US roads.

Although horizontal curves make up a small percentage of total road miles, they account for 25 per cent of all highway fatalities with the majority of crashes on curves involving lane departures. US company Traffic and Parking Control Company (989 TAPCO) has developed the sequential dynamic curve warning system which consists of a series of solar-powered, LED-enhanced flashing signs that are installed throughout a curve. Approaching vehicles, sensed by radar or other ITS device, trigger the controller that wirelessly activates the LED signs to flash sequentially through the curve to warn speeding drivers to slow down. The two-year Technology Partnerships field study will evaluate the effectiveness of the system in reducing vehicle speeds and in reducing the frequency and/or the severity of curve-related crashes. Participating State DOTs include Missouri, Texas, Washington, Wisconsin and Colorado.

    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).

    Through its Transportation Lighting and Safety program, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is evaluating the potential for new lighting technologies and approaches to improve driving safety at night, including new car headlight systems. For the study, vehicle manufacturer Audi AG has provided the LRC with an A7 equipped with adaptive high beam ‘matrix lights’ that allow drivers to benefit from using high beams all the time while selectively dimming a portion of the bea

    A new study by the University of Iowa found that a majority of drivers expressed uncertainty about how many potentially life-saving vehicle safety technologies work. The survey also showed that 40 per cent of drivers report that their vehicles have acted or behaved in unexpected ways. The study, conducted by the University of Iowa Transportation and Vehicle Safety Research Division, examined drivers' knowledge of vehicle safety systems, as well as their understanding and use of defensive driving techniqu

    The world of intelligent transport systems can, it would seem, be just as beset by muddled thinking as any other sector. How else to interpret the baffling announcement in January by the US Federal Communications Commission (FCC) chairman Julius Genachowski that the FCC intends to open up almost 200MHz of spectrum in the 5GHz band to unlicensed users, starting almost immediately? As the FCC itself points out, this would be the largest block of unlicensed spectrum to be made available for Wi-Fi in nearly te
