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. Although horizontal curves make up a small percentage of total road miles, they account for 25 per cen

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.

    Wisconsin's four-year HOT lanes pilot project, launched in May 2008, cost US$18.8 million to construct. Halfway into the project, which uses variably priced, or dynamic, tolling to improve highway efficiency, the benefits are mounting. The problem was obvious, and frustrating, to anyone who ever sat in bumper-to-bumper traffic on State Route 167 and watched a lone car whiz by every 20 seconds or so in the carpool lane. But for planners at the Washington State Department of Transportation, the conundrum was

    Refinements in the data available from the US Federal Highway Administration will improve road management across America. David Crawford reports. In August 2017, the US Federal Highway Administration (FHWA) issued the first results from an upgraded version of its National Performance Management Research Data Set (NPMRDS). Developed to identify the locations and times of high congestion affecting traffic flows along America’s 259,000km (161,000 mile) national highway system, this is a key resource for sta

    Hugh Colton, Georgia DOT details move to improve urban traffic control in the Atlanta area. With a significant proportion of traffic using freeways and toll-ways, along with a significant investment in roadway infrastructure, urban arterials are often the poor relation when it comes to ITS investment. Hitherto the primary means of Urban Traffic Control (UTC) has been the ubiquitous traffic signal. Many traffic signals still operate in a standalone mode and traffic detection is often broken, leaving the sign
