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.

    Urban traffic control is a well-defined and practised art. Nevertheless, there are technologies here and on the horizon with the potential to revolutionise how we do things. By Gavin Jackman and Andrew Kirkham, TRL, and Jason Barnes. Distributed monitoring and control of urban traffic networks and flows is nothing new. PC-based Urban Traffic Control (UTC) is now well established and operating in many locations around the world. However, it is worth considering the effects of the huge growth in the use of sm
