The Utah Department of Transportation (UDOT) has installed a new US$750,000 electronic sign system on Interstate 80 in Parleys Canyon that will allow engineers to adjust the speed limit during storms or icy weather. Eight electronic signs are in eastbound lanes, and seven in westbound lanes. Data from road sensors shows the road condition, along with the canyon’s temperature and humidity and traffic speed, while cameras will show visibility, enabling traffic engineers to remotely adjust the speed limit s

The first over-height vehicle detection system (OVDS) in Qatar has been launched at the Duhail intersection in Doha. The new system will help provide greater control over trucks and protect bridges and tunnels, the Public Works Authority (Ashghal) said yesterday. The system is operated and controlled by the traffic signal control room (TSCR) at Ashghal. The OVDS uses integrated sensors or height detectors, electronic message board and CCTV, to detect vehicles that violate the maximum permitted height of

Japan's Mitsubishi Heavy Industries (MHI) has received an order to supply Sri Lanka's Road Development Authority (RDA) with the country’s first highway traffic management system (HTMS). The system, slated to go on-stream by the end of 2014, will also be MHI's first installation of its full-scale traffic management system for expressways. As part of a package agreement, MHI will handle all aspects of the project from engineering, procurement and installation to adjustment and training. The HTMS will b

US state Departments of Transportation (DOTs) are gearing up to meet the challenge of maintaining a high level of service during the winter without the benefit of additional financial resources. High-tech solutions like GPS guidance systems and low-tech products like potato juice are helping states to cut costs, improve efficiency, and minimise environmental impacts. The Alaska Department of Transportation and Public Facilities uses a variety of advanced technologies to combat extreme winter weather and

A new road weather information system developed by Hyundai Engineering and Construction (Hyundai E&C) can provide drivers with reliable real-time traffic and road condition information, says the company. The system, developed in concert with Hyundai Motor Company and Hyundai Mobis, can help alert drivers of traffic congestion and potentially hazardous road conditions up ahead by collecting data from all cars, such as ambient temperatures and road conditions. It also processes information from various roa

Vaisala’s new road weather management software, RoadDSS Manager is, says the company, more than just a road weather data display. It is designed to be the perfect management tool to help road managers streamline the winter maintenance decision process. RoadDSS Manager combines the sources of road weather information into a single tool, enabling users to access all the information they need to make decisions quickly and then log and monitor operations. In addition to the standard road weather data from

Vaisala's collaboration with the Idaho Transportation Department has been recognised by the US Road Safety Foundation and Federal Highway Administration (FHWA) as winners of the biennial National Roadway Safety Awards. The award winners were chosen for reducing fatalities and injuries on roadways through excellence and innovation in operations, planning, and design. The Idaho Transportation Department, using Vaisala's pavement sensors that calculate grip or friction values, found that this value can als

India’s Hyderabad Metropolitan Development Authority (HMDA) has developed its Comprehensive Transportation Plan-2014 for Hyderabad Metropolitan Area and a draft Intelligent Transportation System (ITS) Master Plan and is seeking public comments and suggestions. The Comprehensive Transportation Plan, prepared by consultants LEA Associates, envisages a total investment of US$35 billion over the next thirty years.
