Ross, H. R. A. Krammes, D. L. Sicking, K. D. Tyer, and H. S. Perera, NCHRP Report 358: Recommended Practices for Use of Traffic Barrier and Control Treatments for Restricted Work Zones.
Guidelines for Using Late Merge Traffic Control in Work Zones: Results of a Simulation-Based Study.
Published reports of the NATIONAL COOPERATIVE HIGHWAY .
This Synthesis of Practice focuses on speed management for work zones on roadways with ordinary (pre-construction) speed limits of 45 mph and above such as freeways, tollways, multilane divided rural highways, and many two-lane and multilane undivided rural highways.
Treatments Used in Work Zones .
Between 2005 and 2011, the number of traffic fatalities in the . Guidelines for Detection and Remediation of Soluble Salt. declined by 11,031, from 43,510 in 2005 to 32,479 in 2011. This decline amounted to a reduction in traffic-related deaths of 2. percent, by far the greatest decline over a comparable period in the last 30 years Guidelines for Detection and Remediation of Soluble Salt Contamination Prior to Coating Steel Highway Structures.
Traffic control refers to the use of temporary traffic control devices to. .Flexible drums are preferred for highway work zones and are required for night-time operations on highways.
Traffic control refers to the use of temporary traffic control devices to protect workers and to move road users safely through a work zone. A traffic management plan is usually required to outline the traffic hazards, and to specify the measures needed for traffic control. Use barriers or other devices to channel traffic, and, where possible, provide a physical separation between the work zone and passing traffic. Administrative controls: If possible, plan most of the work during non-peak hours or night time when the traffic is light.
A Jersey barrier, or Jersey wall, is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction, as well as temporary and semi-permanent protections against landborne attack such as suicide vehicle bombs.
