ROADSIDE DESIGN 10-37 1 0.2.3 Barrier Tv~es There are four types of barrier in common use in New York: cable guide rail, corrugated metal or W-beam guide rail, box beam guide rail, and concrete barriers. They are discussed in the following subsections in order of increasing rigidity. Note that W-beam may be mounted on
Observed state practice is to use ï¬ are rates closer to those for permanent concrete barriers from Table 5.7 of the Roadside Design Guide. 5.6.4 End Treatments Desirable end treatments for a temporary barrier are dis- cussed in Section 9.2 of the Roadside Design Guide. 5.6.5 Crash Cushions Crash cushions are protective systems that prevent...
The Guide to Road Design – Part 6: Roadside Design, Safety and Barriers provides an introduction to roadside design and in particular guidance on roadside safety and the selection and use of road safety barrier systems. Roadsides have to accommodate many features that support the road and the safe and efficient operation of traffic, and have to be designed with regard to environmental...
This distance is measured from the upstream end of the roadside hazard, along the roadway, to the point at which the vehicle is assumed to leave the roadway. The AASHTO manual provides recommended runout lengths, based on the design speed of the roadway and the given traffic volume, to use in determining the barrier length-of-need.

There is confusion among civil engineers in the United States regarding the applicable design method and the appropriate impact load for sizing the moment slab of roadside barrier systems atop MSE retaining walls. The design method and impact load discussed herein have been used successfully for more than 15 years to size the barrier moment slab and to determine the magnitude of loads applied...
Imperial researchers have designed a unique curved barrier which can protect people from the damaging effects of air pollution. With air pollution becoming an increasingly dangerous global health challenge, researchers are constantly working on innovating novel solutions to tackle these 21st century problems. At Imperial College London, researchers are using airflow modeling techniques
Guidelines for the installation of median barriers presented in the AASHTO Roadside Design Guide have remained essentially unchanged for more than 30 years. In recent years, the need for improved guidance has prompted several states to reevaluate their guidelines and has also precipitated a nationwide research project administered by the Transportation Research Board.
