Switzerland-based Youngman Group’s Ecolite LED mobile lighting tower extends the company’s existing mobile and stationary ceramic discharge lamp models. The Ecolite LED aims to satisfy growing interest in LED lighting across the building industry by offering lower power consumption, low heat output and long life. The Youngman unit is equipped with an array of 400 individual LEDs mounted across four adjustable holders providing a total light output of 91,800lumens.

A major programme to upgrade traffic lights at 78 junctions and 100 pedestrian crossings across Norfolk with new energy-saving LED signals from Siemens was set to finish this month. The retrofit project to supply, install and maintain all 178 sites is estimated to provide up to 78% power consumption and carbon savings for Norfolk County Council (NCC). The new contract includes an innovative cost benefit payback solution provided by Siemens Financial Services.

Characteristics of traffic speed and flow in managed freeways - *Dr Adrian Withill. In order to maximise the benefits of existing infrastructure, in terms of reduced delays and increased safety, many governments have recently been introducing projects that measure traffic speed and flow and automatically introduce advisory or mandatory speed limits. Such schemes tend to offer relatively quick wins at relatively lower capital costs than traditional highway construction. In light of the current world economy,

Gatso recently unveiled its new T-series platform for speed enforcement during Intertraffic Amsterdam. The platform is said to consist of a range of innovative technology design and components, housed in a revolutionary new cabinet. It includes the latest high-tech components for image capture, machine vision, and detection.

Clearview Traffic Group (CTG) has secured a contract for the installation and maintenance of automatic traffic monitoring equipment on behalf of Transport for London (TfL), the integrated body responsible for the capital’s transport system. As part of the contract, CTG will install a number of additional Automatic Traffic Counter (ATC) sites, as well as continue to maintain and repair nearly 200 existing ATC locations in and around the city of London. The ATC sites include equipment, ancillary devices and s

Siemens has been asked by Leeds City Council to provide a new city-wide IP-Communications network. The network will initially be used for a new Urban Traffic Management Control (UTMC) system and may later support CCTV as well as the extension of UTMC to more than 1,000 sites. The UTMC system in Leeds controls around 400 signals in Leeds and Calderdale and is said to be key to keeping traffic moving through the large West Yorkshire city. Reliable communications are crucial, but to date this is said to have c

New rules in the US mean that electric vehicles will require noise generation equipment. This covers electric vehicles and hybrids as well as motorcycles, medium and heavy trucks and buses. It specifies that the alert sound must be sufficient to allow a pedestrian to detect a nearby EV or PHEV operating at constant speed, accelerating, decelerating and operating in any other critical scenarios. It must reflect the minimum sound level emitted by a motor vehicle that is necessary to allow visually-impaired an

The project to install Variable Message Signs (VMS), recently approved by Staffordshire County Council, will provide motorists with important travel and road safety information, and up-to-date warnings of incidents and accidents to help them avoid trouble spots and possible congestion. Michael Smith, the county council’s senior highways project engineer, said: “‘In addition to representing good value for money, the company has a sound track record in this area having already successfully supplied and instal

Transport and traffic analysis nowadays tends to switch between static analysis modelling for large scale studies and microsimulation for finer grain work, with perhaps the mesoscopic model also finding a place for mid-level. Most producers make software tools at all three levels and increasingly package them together. Spanish firm TSS (Transport Simulation Systems) has gone one better with its latest release Aimsum 7, by giving it the capacity to "zoom in" from a larger scale mesoscopic model to a smaller
