The automated road weather information system (RWIS) is used to continuously record the current and predicted status of driving conditions on the road network. By the end of 1999 there were more than 60 road weather stations in the Baltic countries and an additional 275 stations in Finland. The four countries have joined resources to develop a common Internet interface (www.balticroads.net) by which to share the existing RWIS data collected around the Baltic Sea region more effectively with the transport sector and other road users. The overall goal of the Internet interface is to provide better access to accurate road weather information for the transport industry and the driving public, thus resulting in better service and improved traffic safety. The cooperation among the national road administrations improves utilization of the information from the existing RWIS in road maintenance operations. The possibilities to expand the Internet service are endless. It is possible to access the service through an Internet connection at border stations and gas stations, as well as to transfer the data via local radio operators and text-TV providers. The vision is also to extend the Internet service to cover road weather data from the neighboring countries in the Baltic Sea region. The Baltic RWIS Internet interface provides current data on local road weather such as road and air temperature, type of precipitation, road condition, wind speed and direction, and dew point and humidity.
