Further Development of RWIS and Its New Potential Marketplaces in Latvia

In the past, development of road weather information system (RWIS) mainly reflected in gradual expansion of a network of environmemtal sensing stations (ESS) along the main roads in Latvia. Since a concept of common platform of Intelligent Transportation System (ITS) became mature and has a Pan European framework, RWIS as its integral part, got opportunities for more effective usage, but at the same time, new challenges of data accessibility and interoperability occurred. The presentation deals with ongoing projects and future vision about: how existing ESS stations should be built up to a multifunctional road, traffic and environment control points; how RWIS of different authorities and other data sources should be integrated; how to cover road network (including secondary routes) with low-cost sensors and provide proper decision-making tool for antiicing strategy and overall road management; how RWIS data can be used wider and processed for new marketplaces in Latvia.
