GRAPHIC INFORMATION PROVISION SYSTEM ON METROPOLITAN EXPRESSWAY

Metropolitan Expressway Public Corporation developed and installed graphic information boards on a large-scale project such as is seen nowhere in the world. The intention is to make driving on Metropolitan Expressways safe, smooth and pleasant from an early date, beginning with Variable Message Sign (VMS) providing driver information. The introduction of graphic information boards, how information is displayed, the mechanism for presenting information, and evaluations of their effects are presented. Studies for presentation of graphic information in long tunnels, which will soon be part of the traffic scene in the Tokyo area, are described. For the covering abstract see ITRD E114174.
