To meet its goal of ensuring traffic safety and efficiency by providing accurate up to date traffic information, the City of Colorado Springs in the US has ordered 35 full colour dynamic message signs (DMS) to be installed on public right of ways throughout the city. The signs, supplied by Skyline Products, utilise a Kynar 500 coated aluminium mask over polycarbonate glazing for a 20mm pixel pitch. The red, green and blue LEDs in the pixels are vertically aligned to maximise the cone of legibility withou

Zero standing-traffic related incidents were recorded during UK service provider A-one+’s recent A1 refurbishment project, a result the firm attributes to the deployment of a variable message sign (VMS) package supplied by temporary intelligent transport system (ITS) solutions provider, Mobile Visual Information Systems (MVIS).

The California Department of Transportation (Caltrans) recently completed a smart corridor project on State Route 12 in Solano, Sacramento and San Joaquin counties, and I-5 in San Joaquin County. The project utilises intelligent transportation system (ITS) technology for five electronic message signs and four closed-circuit TV cameras to provide drivers with up to date travel information, enabling them to choose an alternate route in the event of congestion or roadway incidents.

The municipality of Quito is investing US$30 million in a bid to improve transit in the city. The city has also replaced 6,000 old traffic signals and installed almost nine kilometers of fibre optic cable, together with 1,700 cameras. A mobility management centre has been opened, which will monitor traffic and manage the new traffic signal system currently installed at 312 intersections. The city hopes to control up to 600 intersections by late 2014.

The Florida Department of Transportation (FDOT) is to begin work on a US$24 million intelligent transportation system (ITS) network in north-west Florida.

Motorists in Singapore can look forward to improved real-time traffic information and better traffic flow as the country’s Land Transport Authority (LTA) begins works to enhance existing electronic signboards along the expressways. The 380 existing island-wide expressway motoring advisory system (EMAS) electronic signs will be replaced with thirteen new signs. The new signs will be more readable, as they can display text and simple graphics in up to seven colours, including green, cyan and purple. The first
