Best Practices for Road Weather Management Version 2.0
Intelligent Transportation Systems and Winter Operations in Japan
A number of U.S. State DOTs and the FHWA are involved in the development and field evaluation of advanced systems directed at enhancing winter road operations. This body of work is part of State and national efforts to improve the efficiency and effectiveness of snow and ice control operations and to better inform motorists of wintertime driving conditions. The advanced systems under investigation include winter maintenance equipment with enhanced sensors and control devices, information systems for measuring and communicating winter road conditions, higher-resolution winter weather forecasting tools, winter maintenance decision support systems, and improved ways of alerting motorists to wintertime driving conditions and educating them on the potential dangers of driving during winter weather. Work is underway in the United States to integrate some of these advances with other aspects of transportation operations and maintenance as part of the development of intelligent transportation systems (ITS). Research indicates that Japan and several European countries likewise are making significant advances in winter road operations, particularly in the areas of motorist information and system integration.
