Best Practices for Road Weather Management Version 2.0
Building a Road Weather Information Network for Integrating Data from Heterogeneous Sources
The Road Weather Information System for Canada (RWISC) is being implemented to provide a more efficient, sustainable and safer highway system. This is achieved by integrating a Canada-wide network of Environmental System Sensors (ESS) and instrumented vehicles which provide a continuous stream of observation data describing road conditions. Provincial Computer Centres (PC2) acquire data from fixed and mobile ESS stations in real-time. This paper will describe the architecture for RWIN and the development and integration approaches through collaboration between multiple levels of Government and the private sector. The Proof-of-concept and prototyping approaches for validating requirements and effectively engaging stakeholders will be highlighted. Specific approaches towards testing and integration, data delivery, security, and protocols for return of RWISC data to contributing stakeholders will be discussed. The paper will conclude by outlining future phases of the RWIN project, implementation challenges and lessons learned.
