| 摘要： | Difficult road weather conditions cause traffic problems in Finland. Nearly half of wintertime accidents take place during poor driving conditions. Road users are not always aware of how poor and risky driving conditions actually are in winter. In Finland, the use of road transport telematics has been found to be one possible way to reduce the effects of poor road conditions on road safety. One of the solutions that has been tested is a mobile road weather monitoring system. Finnra's traffic management system presently uses a nationwide road weather system that includes around 280 automatic weather monitoring stations and around 180 road weather cameras. It also uses satellite and weather radar information and road weather forecasts obtained from Finland's Meteorological Institute. Traffic is constantly monitored by over 200 automatic traffic monitoring points. Also discussed is the use of a "mobile monitoring station" that gathers information about driving conditions and transmits video images of different sections of roadway. The satellite-based global positioning system is used to gather information transferred to Finnra's Traffic Information Centers. |
