Airport Transport Bus -Automobile Collision Dulles Airport Access Road.

摘要

This accident was determined to be a major accident within the definition of the National Transportation Safety Board because of the technical problems illustrated by the following issues: (1) the lack of appropriate signs to deter wrong-way entry on a Federally controlled and maintained highway; (2) the absence of occupant restraint systems in passenger-carrying buses; (3) the nonutilization of installed seat belts by the driver of the bus;and (4) alcohol involvement and its relationship to wrong-way traffic movements and fatal accidents. The Board recognizes that other issues were present in the accident;this report addresses itself only to the four issues inasmuch as they represent areas of immediate priority. (Author)
