Forecast of road surface temperature and condition in the territory of Prague for the winter period – ICEWARN

In the project, a tool for forecasting road surface temperature and condition, which operatively calculates and updates forecasts, was created. The purpose of the project was to provide forecasts to customers, which include mainly organizations responsible for road traffic: Technical Road Administration of the Capital City of Prague and possibly Prague Public Transit Company and the Road and Motorway Directorate of the Czech Republic (for motorway sections in the territory of Prague and in the immediate vicinity), but also the public.
