Title: Wireless Weather Station for the detection of black ice on roads
Abstract: Keeping the Swedish roads safe during winter months is something that requires large resources and costs society a lot of money. The systems that provide information on road condition today are not enough. There are too few weather stations located around the road network to provide a good spatial resolution to those who decide if there is a need for ice- or snow removal on the roads. To provide a cost effective and completely wireless weather station that can be deployed regardless of access to power or wired communications is something that existed as a desire by the major contractors for the winter road maintenance in Sweden for a long time.A higher spatial resolution of weather conditions in the road network will make it possible to use more focused efforts where the road conditions are not good. This would result in reduced wear on the tools, less fuel consumption and reduced use of salt on the roadway resulting in economic gains and not least environmental benefits.Interviews and questionnaires were the basis for creating a base for a weather station of this kind. While working on weather station data, additional requests and ideas from people who are active in the industry emerged. This has led to the thesis work focused primarily on developing a new sensor system that completely contact-free from the road surface detect what is on the road surface when it comes to distinguish dry, wet or icy road surface.A complete sensor system has been developed that is placed in the roadway and which measures the temperature and uses a sensor that doesn't have any contact with the road surface to detect if the road surface is dry, wet, or if there is ice on it. The sensor system is battery powered and transmits data wirelessly from the road. This makes it possible to use multiple sensors in the roadway, thereby creating a sensor network that can determine what the conditions are at longer distances than in only one point.
