A new solar-powered, wireless automated rotary drum sign system, manufactured by 732 Skyline Products Traffic Division and currently being deployed in Texas, is being hailed as one of the greenest, least expensive, most flexible means of managing traffic flow.

This exclusive technology was designed as part of a breakthrough programme by the 375 Texas Department of Transportation and engineers and consultants 731 Walter P Moore to create more efficient travel through the El Paso, Texas metropolitan area during traffic incidents and closures on the interstate. The new signs require no fibre-optic cable, hard-wired communications or power, making it possible to install them just about anywhere.

The Automated Rotary Drum Sign System is claimed to be the only automated diversion sign of its kind. “Most of the time, they display standard guide sign information. When an incident occurs, information is sent wirelessly and the signs are activated. The drums rotate and provide appropriate detour information,” explains Mark Conway, director of ITS, Walter P Moore.

“Eliminating the need to run power to each site, including trenching, conduit, power, labour and continued maintenance can plausibly save departments of transportation and taxpayers everywhere millions of dollars,” says Adam Lyons, regional sales manager at Skyline Products. “At the same time we are increasing the options for traffic diversion and delivering all the benefits of improved traffic flow, such as reduced driver frustration and reduced CO2 emissions.”

Some 94 sign units, with various message configurations, are currently being installed by long-time Skyline partner, Tri-State Electric, along Interstate Highway 10, US 54 and Loop 375 in El Paso, Texas.

    David Crawford reviews developments in temporary ITS. Widespread take-up of technologies such as Bluetooth and wi-fi are encouraging the emergence of more sophisticated, while still cost effective, ITS responses to the traffic issues posed by temporary road situations such as work zones and special events. Andy Graham of traffic solutions specialists White Willow Consulting says: “A machine-to-machine radio link is far easier and cheaper than reading characters on a plate.” There can be other plusses.

    Hybrid communications to variable message signs increase resilience to natural disasters and enable deployment in remote areas, as Alan Allegretto explains. Variable Message Signs (VMSs) are a common sight and a well-proven means to improve public safety on our roads and highways. ITS professionals rank the VMS as second only to interoperable radios as the most important technology to improve effectiveness during emergency incidents and evacuations. Ironically, however, current systems suffer from one criti

    Dynamic Message Signs : Don’t replace, refurbish and upgrade
    Refurbishing old dynamic message signs can save money and increase technical capabilities as David Crawford discovers. Evidence is growing on both sides of the Atlantic of the scope for retrofitting old or technically out-of-date dynamic message signs (DMS) with new electronic equipment, to save on the costs of installing full-scale replacements. In the last four months of 2014, a number of US states progressed programmes that achieved savings of more than US$1.75 million (€1.56million).

    Wireless bridges widen options for ITS upgrades
    Antaira Technologies’ marketing engineer Brian Roth explains why the increasing capacity of wireless bridges is reducing the cost of expanding and upgrading ITS networks. With more than half of the world’s population now living in cities, the need for efficient transportation of both people and goods has never been greater and that pressure is unlikely to ease any time soon. Indeed in many regions of the world the rate of urbanisation is still increasing as the demand for rural workers continues to decline.
