How does Traffic Scotland work?
Information about current road traffic conditions is either automatically detected by equipment installed on the road network or via CCTV cameras, the Police or the trunk road maintenance companies. Traffic information is entered into Traffic Scotland, which then calculates the response to be displayed on Variable Message Signs and the lane control units located in the overhead gantries. In addition the information can also be distributed using the Traffic Scotland web site and associated WAP and PDA services. The First Generation Traffic Scotland Operator Service also provides information directly to various radio stations and other organisations that subsequently provide traffic broadcasts.
