Abstract

The aim of the projected road weather data monitoring project is to define the objective state of weather and road weather data monitoring for 2007. The data in this context include road weather station data and camera pictures, satellite and radar pictures, weather forecasts in different forms, as well as data on road conditions and road weather forecasts. The definition of the objective is a tool for developing the monitoring system. Six use cases of the monitoring system defined the requirements for the intended state. The most important new requirements came from road maintenance quality control use case. The most detailed requirements came from the traditional maintenance realization. In addition the traffic control has its own requirements for those road sections with variable speed limits and information boards. The present monitoring system meets many of the future requirements. The projected state is illustrated by defining the new and enhanced parts of the system in 2007. All together nine new parts were defined, including issues like enlarged and better-equipped road weather stations and camera network, improvements to data storages, processing, and presentation, and also a new centralized data transmission system for receiving and delivering road weather data. In addition to the implementation projects a number of development ideas were proposed. The most important future development items are road weather models and forecasts as well as floating car road weather monitoring.
