TRUCKS AND BUSES: ROADSIDE SAFETY CONSIDERATIONS

A typical traffic stream is composed of a wide assortment of vehicles ranging from motorcycles to tractor trucks with multiple trailers. This paper focuses on the heavy vehicle segment of the traffic stream beginning at about 5000-lb mass and includes pickups, vans, school buses, intercity buses and tractor-trailers; this segment will be denoted as "trucks and buses" for convenience. The amount of annual truck and bus travel in the U.S. between 1960 and 1980 has increased from 160 to 390 billion vehicle miles, a factor of 2.4, and it is projected to increase by 1990 to 550 billion vehicle miles. During this same period, the percentage of buses and trucks in the traffic stream will increase from 18 to 28 percent. Thus, it is evident that this group is becoming a more important consideration in highway design. One important issue is the possible effects that the increased presence of trucks and buses will have (and is having) on highway safety in general and roadside safety in particular; attention will be primarily directed to the latter.
