TRB'S STUDY OF TWIN-TRAILER TRUCKS

The Surface Transportation Assistance Act (STAA) of 1982 legalized the nationwide use of twin-trailer trucks on Interstate highways and other designated primary routes. In this paper will be reviewed what is known to date about the effect this legislation has had on the trucking industry--who is using these vehicles, where, and for what purposes. This information, coupled with earlier research findings concerning twins and other heavy trucks, will be used as the basis for a brief discussion of the likely effects of twins on the design, maintenance, and operations of highway facilities. Specific topics will include road geometry, pavements, bridges, and traffic capacity. Throughout, references will also be made to other new trucks legalized by the 1982 STAA--the 48-ft single-trailer truck and 102-in.-wide trucks.
