Sponsorship opportunities of the Georgia 511 NaviGAtor system include the 511 telephone system, which receives 1.6 million - 2 million calls annually; 511 website, which exceeds three million hits annually; over 600 roadway signs statewide, reaching more than three milli

The UK Highways Agency is trialling a system to add commercially available traffic data to its existing sources to monitor how well traffic is flowing on England's motorways and strategic roads. Similar data sources are already used by satellite navigation devices, smartphones, and applications like Google maps. Better real-time data will allow agency staff to respond more quickly to incidents and identify delays and communicate them to drivers so they can take alternative routes if necessary.

David Crawford looks at recent developments in travel information display systems. It is important to remember that we are investing in Real-Time Passenger Information [RTPI] to increase ridership," says Robert Burke, Managing Director of New Zealand transit tracking technology specialist Connexionz, which has been involved in at-stop and remote passenger information since 1995. "Superior information improves the perception of public transport reliability and gives the passenger more choices and greater con

Deryk Whyte provides an overview of how the New Zealand Transport Agency's InfoConnect concept was developed. Historically, the New Zealand Transport Agency (NZTA) (formerly Transit New Zealand) has faced challenges in communicating effectively with road users, its customers, about highway-related events or incidents in a timely, accurate manner. Prior to 2007, Transit relied on a third-party organisation to collect and disseminate national road condition information. This often resulted in incomplete infor

The use of a Vehicle Data Translator will allow every vehicle on a given segment of road to contribute to a highly accurate, readily accessible source of localised weather information, thus improving safety in all conditions. Sheldon Drobot and William P. Mahoney III, US National Center for Atmospheric Research, Paul A. Pisano, USDOT/Federal Highway Administration, and Benjamin B. McKeever, USDOT/Research and Innovative Technology Administration, write. On the morning of June 10 2009, under the cover of den

The Danish Road Directorate and Daluiso have developed a new type of road sign to make road works and maintenance tasks more efficient. Called 'swap signs', their function is to flap open/shut near road works, spring cleaning or grass cutting by contractors.

(QTT) is promoting the greater use of mobile technologies to provide infill between fixed Road Weather Information System (RWIS) infrastructure. It is, the company says, a means of reducing the expense of providing comprehensive, network-wide coverage, particularly in geographic locations where the sheer number of centreline miles causes cost to

Tools to support operational decisions in winter maintenance can remove subjectivity and increase efficiency; Vaisala's Danny Johns talks about latest developments Even the presence of trees at the roadside can have an effect on temperature An effective Road Weather Information System (RWIS) network can save a local road authority or jurisdiction tens of thousands of dollars or Euros'-worth of labour and consumables in a single night. Get those winter maintenance operations right over just three or four nig

The AQM 60 from Quixote Transportation Technologies (QTT) is an air quality monitoring system designed to measure a wide range of air quality parameters in a cost-effective, compact package. The system measures the top six pollutants considered harmful by the US Environmental Protection Agency and integrates with road weather information systems, advisory radio systems and ITS software platforms to provide weather, traffic and air quality data on one system. As QTT points out, monitoring air quality data ne

Inrix will collaborate with the Ohio Department of Transportation (ODoT) to use the company’s traffic information and cloud-based analytics to further the state’s goal of clearing roads statewide within three hours after major storms. “Restoring travel to normal conditions as quickly as possible not only improves public safety but keeps people and commerce moving across the state,” said Ted Trepanier, senior director of public sector, Inrix. “We’re providing Ohio with an objective, data-driven approach for
