 Most of the branch offices of Metro/Shadow have working relationships with the local Department of Transportation (DOT), local and state police, and government agencies to gather and distribute traffic information through their affiliates.Other traffic information is gathered by listening to police/fire/rescue scanners , phone calls, viewing traffic cameras, and visual reports made by reporters in fixed-wing and/or rotary-wing aircraft.In September 2008 Westwood One announced that they were reducing their Metro/Shadow operations centers from 60 offices to 13 regional hubs.
