A training program for professional drivers is reviewed. The effects of driver factors, as well as their training, on accidents is presented....
Truck Operating Characteristics in Relation to Safety
For a two-year period large truck crashes on the interstate system in Washington State were investigated using a case-control method. For each large truck involved in a crash, three trucks...
Design Considerations for Trucks in Work Zones
In an Eastern state a 3. 8 mi (6. 2 km) work zone had 14 accidents during a project duration of 120 days. Eleven of the 14 accidents occurred at temporary crossovers where traffic was...
Accommodation of Large Trucks: Traffic Control Issues
The objective of this paper is to identify ways that large trucks can be accommodated safely and efficiently through traffic control. Traffic control is herein defined as encompassing...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
Evaluation of Air Quality Methods in the Asbestos Work Area
Air monitoring is a technique that is routinely used to measure the level of asbestos in a given airspace. This technique has changed significantly since its first use in the asbestos...
