Air Quality & Weather Systems

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.

Jon Tarleton, Quixote Transportation Technologies, Inc., talks about developments in mobile weather information gathering Quixote Transportation Technologies, Inc. (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

David Crawford investigates the potential of new projection technology. Fifty years on from its invention of the microchip, US company Texas Instruments (TI) has compressed the technology into a surface area of just 4.3mm. As such, it forms the heart of a new Pico Digital Light Processing (DLP) system that is set to transform travel information delivery for millions of users on the move - by making it projectable.

Daktronics has announced the addition of a new ITS LED display to its current line of widely used Vanguard Dynamic Message Signs (DMS). The Vanguard VM-1020 Dedicated Dynamic Message Sign, or DDMS, is designed to provide a reliable signage solution dedicated to travel time, toll rate (such as high-occupancy toll lanes) and other managed lane applications.

High Sierra Electronics is claiming a unique approach to Road Weather Information Systems (RWIS) with the launch of its newest product, the Model 5470 NTCIP Mini-RWIS Remote Processing Unit. This device is the heart of a non-proprietary, open architecture NTCIP-compliant Environmental Sensor Station (ESS), designed for primary deployment within existing or new ATC cabinets and Dynamic Message Sign (DMS) cabinets. The company says this approach allows simpler implementation at a lower cost than traditional i
