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...
Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
Rehabilitation of Highway Bridges: Design and Operational Considerations
The design of a rehabilitation of a bridge which must maintain some lanes of traffic requires special consideration of construction procedures and traffic control, which are discussed...
