Road Weather Information System (RWIS) & Maintenance Decision Support System (MDSS) Economic Value Tool (EVT)

Maximizing roadway safety, mobility and efficiency, while minimizing maintenance-related costs and reducing environmental impacts, is the common goal of winter maintenance engineers around the globe. Road Weather Information Systems (RWIS) and Maintenance Decision Support Systems (MDSS) (or Road Decision Support Systems) have proven track records in enabling road authorities to meet the aforementioned goals. However there are many more benefits that these systems provide both in economic terms and other less tangible benefits that have largely been overlooked by previous studies. This paper describes a tool whereby local authorities can plug in their known operational and economic parameters to instantly calculate potential benefits of RWIS and Road Decision Support Systems.
