The divested product lines comprise of three non-weather road transportation
products: a distance measuring instrument which measures the exact linear
distance travelled by a vehicle; a portable traffic data analyzer, which
provides data such as the number of vehicles, speed of the vehicles and length
classifications for short-term studies; and highway advisory radio systems which
provide real-time information to motorists via AM radio signal. All products are
currently used in USA by various governmental and public works entities,
including State Departments of Transportation.

The product lines were a part of the acquisition of Quixote Transportation

in providing the best road weather sensors, service, and decision support
software available to the transportation community. Vaisala also strives to
