Samenvatting
Road administrations in many countries use a Road Weather Information System (RWIS) as the core component for effective roadway maintenance and operations, and some have been doing so for decades. Through the effective integration of systems, road weather sensor data are used extensively in decision-making as it pertains to roadway maintenance, highway operations, and management processes. This report provides an overview of the various practices that are currently in use, and is based on responses to a survey from a number of countries that are represented on PIARC Technical Committee 3.4 on Winter Maintenance.
