The Midlands Driver Information System: operational experience and findings

Stage 1 of the Midlands Driver Information System has been operational since October 1996. With five months of experience of operating the system this paper is able to report both the status of the project overall and the ways in which the largest driver information system in England is being used by the 14 police forces within its boundaries. Within the project driver information is provided by variable message signs located at key route choice junctions in the network. Two signs are located prior to each junction. The road network which is covered by this system is limited to the motorways within the boundary and those trunk roads which are likely to be able to carry diverted traffic for most of the day
