Air Quality & Weather Systems

South Gloucestershire Council has purchased two mobile speed indicator signs (SIDs) from UK company Traffic Technology, which will be used to monitor traffic speeds at sites where there is a community concern about speeding vehicles or a history of speed-related injury accidents. The signs will be installed following a site survey to ascertain whether there is a problem with inappropriate speed. SID is a rugged, lightweight radar activated speed indication display that can be used at temporary or perm

SES America (SESA) and contractor partner Traffic Control Devices has completed final commissioning of walk-in dynamic message signs (DMS) for the Harris County Toll Road Authority along Interstate 10 and US 225 to enhance travel time information and alternative routing advice. SESA manufactured an energy efficient LED display, the Messenger 6000, requiring no ventilation or cooling systems, dramatically lessening maintenance and labour costs. Conforming to existing HCTRA standards and requirements, SES

A research project that gathers information on vehicle emissions in Birmingham got under way last month as part of the UK Government’s ongoing efforts to meet EU air quality targets. In December 2015, the UK Government announced plans to introduce Clean Air Zones in cities, including Birmingham, by 2020. These zones will not affect private car owners, but would aim to discourage the most polluting vehicles, such as old buses, coaches and lorries, from entering the zone. The new project, developed by B

The City of Houston has awarded Trafficware Group a contract to upgrade the city’s central traffic management system, a project that also includes converting all 2,500 intersections from older technology to Trafficware’s Patriot V76 traffic control software and upgrading to its transportation management platform, ATMS.now. The new ATMS.now software platform will allow the City to integrate a number of devices so they no longer have to operate as disparate systems and can react quickly to incidents and c

SES America’s energy efficient M6000 series of dynamic messaging signs, which require no cooling or ventilation systems, has received full approval for application on the Georgia highway system. The M6000 comes in assortment of sizes and is available in both colour and amber with the latter offered in solar or mains power versions.

In an effort to reduce the number of accidents caused by slippery road conditions, Swedish companies Nira Dynamics and Infocar Training have equipped a fleet of 80 vehicles with software for detecting road surface conditions in real-time. Road surface information (RSI), developed by Nira, continuously monitors the quality and tyre grip level of the road surface, without stereo cameras, adaptive suspension or other expensive sensors. Using sensor fusion based algorithms, RSI determines the level of road r

A village in Derbyshire, UK, is tackling the issue of speeding drivers by installing the latest Swarco Traffic moveable vehicle activated signs (MVAS), lightweight portable signs designed specifically for parish councils to improve road safety and encourage safer driving speeds. Signs are installed at either end of the main road through the village, although there are three pairs of locations where the signs can be placed. Approved for use by Highways England, they are simple to deploy, feature a besp

Lufft USA’s new high quality WMO-compliant weather sensor, the WS3000, part of the company’s new WS1000 series, measures air temperature, relative humidity and air pressure. Relative humidity is measured by means of a heated capacitive sensor element; a precision PT100 measuring element is used to measure air temperature.

A study by the US Federal Highway Administration’s Highways for Life has found a small but consistent reductions in mean and 85 percentile speeds on dangerous bends through the use of Tapco’s BlinkerChevron dynamic curve warning and guidance system (DCWGS) instead of static warning signs. The system's detects oncoming vehicles up to 90m (300ft) from the curve and will trigger the flashing LEDs on the signs if the vehicle’s speed exceed a predetermined level to warn the driver of the dangerous curves with e
