This article describes the use of variable message boards to guide visitors driving into Cambridge, England, to appropriate car parks that are not already full. Whereas some earlier variable message board systems in other cities are intended mainly for local residents, the Cambridge boards are designed to be equally useful to local and visiting drivers. They will direct drivers to the car park nearest to their destination; the five city centre car parks are all sufficiently close to each other to be interchangeable. The signs always guide to the most convenient car park with spaces; ordinary fixed signs display the route between the main junctions. The system assumes that most people entering Cambridge want to visit either its historic city centre or its major shopping area less than 1 km away. The 16 message signs will be operated by Cambridgeshire County Council's traffic control computer, using information from underground detectors counting vehicles entering and leaving the car parks. The new system is expected to lead to more efficient use of car parks, although it was introduced to prevent queueing vehicles from impeding traffic management.
