詳細(xì)介紹

Driving Condition Codes

All weather phenomena that affect driving conditions are simplified into one variable, which we call the road condition code. Road surface condition (dry, wet, icy, …), precipitation amount and type, visibility and many other parameters are considered. A road condition code is chosen to represent the most significant phenomenon that is measured or forecasted to be present. Road weather forecasts are based on the combination of Vaisala′s atmospheric weather model and road weather model. In addition, the effect of possible road maintenance actions, like plowing and salting the roads by national road authorities, are taken into consideration to provide a comprehensive view of the road conditions. The predicted maintenance actions are based on the assumption that the treating has been executed according to the common winter maintenance policies. Please note that similar conditions can lead to different codes in different regions. For example, in countries where using winter tires is mandatory, small amounts of snow or frost are considered less severe than elsewhere.

Resolution and coverage

Most of the content in the service depends on local data sources, which causes the resolution and the set of parameters to vary per region. Atmospheric weather forecasts and satellite data are available globally and resolution varies between 1 km and 10 km. Additionally radar data is available in selected markets. Road condition forecasts are currently available for most of Europe, but new regions and countries can be added upon request. Resolution varies between 2 km and 10 km, depending on the region. Resolution of any area can be improved upon request. All the key factors affecting local road conditions (see illustration) are analysed and taken into consideration in road weather forecasts. However, maintenance activities and traffic information are used only where data is available.

Vehicle Sensor Data

It is possible to integrate sensor data from vehicles into the Road Weather service. Connected vehicle sensor data could be effectively utilized as an additional data source for improving road weather forecasts. Typically, cars are a good source for detecting local precipitation events and the presence of water on the road. Additionally, cars can provide temperature information, especially in areas where road weather stations are scarce or their data is not available. Currently, there is no third-party car sensor data that would be available for all customers, but Vaisala is capable of aggregating and utilizing customer-specific data sources.
