Road Weather Infomation Systems

The RWIS, originally tailormade by ITS Technology in close cooperation with, the Swedish National Road Administration (SNRA) is one of the world’s most comprehensive networks of its kind.

The RWIS integrates some 700 field stations in a national roadside datagathering system which saves lives and cuts costs in a Nordic Climate that is extremely hazardous.

The RWIS is, in fact, road traffic intelligence on a national scale in general and on a local and human-related scale in particular.

This gigantic ITS solution, since long positively evaluated, can be individually adopted to specific road, traffic and climatological conditions anywhere in the world.


Please have a look at the SNRA’s Road Weather Information System on the Internet, (in Swedish).
