Adverse weather conditions have direct impacts on road traffic, principally affecting speeds and road capacity levels. From an operational point of view, it’s therefore important to know how such impacts might affect traffic conditions and provide useful information to road users.

In recent years, the availability of data, analysis and prognosis on such aspects has increased a lot because of more meteorological sensors and information technologies installed along the infrastructures.
