A New Tool to Help Keep Roads Ice- and Snow-Free

Testing Begins This Winter

The National Center for Atmospheric Research (NCAR) and the Federal Highway Administration (FHWA) are testing a Web-based system for weather forecasting and winter road treatment that could soon save lives, cut costs, and help keep millions of drivers on the move. Highway officials and road crews in Des Moines and Ames, Iowa, will test the Maintenance Decision Support System (MDSS) February 3 to April 4.

Motor vehicle accidents involving bad weather (largely ice and snow) claim the lives of more than 6,000 Americans and injure almost half a million people each year. Nearly half of the nation’s state transportation departments have already signed on as stakeholders in the MDSS (see "On the Web" below), along with more than a dozen private firms. The latter are considering developing products and services around the core capabilities of the system.


The MDSS will help agencies better gauge where and when to use road treatments. This means providing more than a generic outlook such as "snow likely tonight," according to NCAR scientist William Mahoney, who is overseeing the development of the MDSS. "We need forecasts that are more specific, more timely, and tailored for decision makers who are not meteorologists."

Currently there is no national standard for linking weather outlooks to road conditions. Pavement can freeze or thaw in minutes over small areas, and it’s difficult for road crews to handle all of these variations efficiently. The FHWA launched an initiative to address these and other weather-related hazards in 2000, choosing NCAR as the project leader because of its experience in developing short-range, fine-scale computer models and decision support tools.

To develop a prototype, NCAR has been working with the U.S. Army’s Cold Regions Research and Engineering Laboratory, the National Oceanic and Atmospheric Administration’s Forecast Systems Laboratory, and the Massachusetts Institute of Technology’s Lincoln Laboratory. The end result pulls together existing road and weather data to create a user-friendly picture.

The MDSS uses several computer models to project hour-by-hour weather and road conditions up to two days in advance, with an update every three hours. The system will allow its users to

  • view predicted weather and road conditions
  • monitor the potential for deteriorating road conditions
  • predict the impact of upcoming weather on specific road segments
  • assess treatment recommendations based on proven rules of practice
  • devise a plan for anti-icing, deicing, plowing, or other road treatment

In short, says Mahoney, "Users can pick a route, look at conditions, see what would happen if they didn’t take any action, and ask the system for a recommended treatment." According to FHWA administrator Mary Peters, "Having access to proper weather and road condition information before and during adverse winter weather conditions will help transportation system managers take appropriate measures to make keep roads open. MDSS will help make roads safer." The system is also expected to save money and help the environment by fine-tuning the amount of chemicals needed to treat roads. In addition, it will help state agencies identify windows of good weather for highway repair and maintenance.

Three state-run maintenance garages serving highways across central Iowa will put MDSS through its paces this winter. Each plowing route’s predominant characteristics, such as pavement type, will be specified in advance. With such detail in hand, the system can assess how temperature combined with snow or ice will affect the road surface. Ultimately, users will be able to ask the system to track features as specific as a single bridge paved in concrete along an asphalt road. Using the MDSS display interface and an Internet connection, anyone interested will be able to view a portion of the real-time displays being used in the Iowa simulations.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
