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

Idaho Transportation Department’s (ITD) research program has initiated a project to evaluate an innovative new wildlife-detection system that may bring improved safety to area highways and reduce personal injury and property damage. The project is the result of a request from ITD’s northern Idaho office, and is a partnership between ITD and the Western Transportation Institute (WTI) of Montana State University. Collisions between wildlife and vehicles can be a big problem, and common in rural states such

Rhode Island-based message sign manufacturer SES America recently played host to state governor Gina Raimondo and Warwick Mayor Scott Avedisian. The occasion enabled SESA president Phil Perut and his team to show their expertise in manufacturing dynamic message signs for highway use, along with the latest technology such as DMS Connect, a sign directly connected to the cloud to provide real time travel information and the latest solar powered sign technology.

A system designed and installed by Swarco Traffic and using water level sensing technology from OTT Hydrometry, is being used in an intelligent flood warning system that has been installed at a ford in Kenilworth, Warwickshire, UK. The system monitors water level in the Finham Brook where it passes under the A452, and warns drivers when potentially dangerous conditions arise.

Transport for London (TfL) has launched a new five-year industry-led programme to reduce the emissions of London's freight and fleet operators. The programme will work across the industry to increase the availability and uptake of low emission vans and lorries. It will bring together freight and fleet operators, vehicle manufacturers, fuel providers and the public sector. TfL says that 85 per cent of London's goods are transported by road and that freight makes up 17 per cent of London's road traffic.

Advanced traveller information system (ATIS) solutions provider Iteris successfully disseminated real-time actionable traveller information to residents and travellers in Virginia, West Virginia, South Carolina and Georgia during the record-breaking storm that brought up to 40 inches of snow in parts of the US East Coast. A snapshot of Iteris’ system dissemination statistics showed that: Telephone calls to the 511 phone system increased 231 per cent; Website user sessions surged by 1,210 per cent; Mobile ap
