TRUCK EQUIVALENCY

A TWO-LANE, DUAL-DUAL, 50 MPH, LEVEL, TANGENT ROADWAY HAVING A 1967 AADT OF 68,000 VEHICLES WITH A HIGH PERCENTAGE OF TRUCKS WAS STUDIED UNDER UNINTERRUPTED FLOW CONDITIONS. A RELATIONSHIP BETWEEN MIXED VOLUME (CARS AND TRUCKS ON A LOCAL ROADWAY) AND EQUIVALENT PASSENGER CAR VOLUME (ONLY ON AN EXPRESS ROADWAY) WAS DETERMINED FOR 20, 40, 60 AND 80 PERCENT TRUCK GROUPS. THE PASSENGER CAR EQUIVALENT OF TRUCKS WAS FOUND TO APPROACH A VALUE OF TWO AS THE PERCENT OF TRUCKS IN THE STREAM APPROACHED 100 PERCENT. THE RELATIONSHIP BETWEEN CARS AND TRUCKS WAS DETERMINED ON THE BASIS OF EQUAL SPEEDS. /AUTHOR/
