Caltrans improves roads with new automated warning system

Caltrans (California’s Department of Transportation) has embarked on a new project that will enable road users to receive road and traffic updates in real time. By installing an automated warning system (AWS) – comprising inductive loops, roadside weather stations, visibility meters and, soon, Bluetooth detectors too – onto state highways, data from roads can be collected and information such as weather reports, incidents, traffic delays and roadworks, can be relayed to drivers via variable message signs and a Caltrans mapping app. Caltrans’ new AWS will help enable drivers to make better decisions when planning their journeys, ultimately helping them to avoid congested areas and drive on safer routes.
