MGA Research Corporation has conducted a limited study on three curb types that have been designed by the State Highway Departments of the States of Arizona and New Hampshire using the Highway-Vehicle-Object-Simulation Model (HVOSM). The purpose of this study was to evaluate what effect these curb designs would have on the guidelines governing the placement of longitudinal barriers. In order to make any determination, the HVOSM results were used to create bumper trajectory plots which showed that all three curb types cause responses which are within the same range or even less extreme than those caused by curbs presently in use. This led to the conclusion that the longitudinal barrier placement guidelines should not have to be modified when considering the Arizona and New Hampshire curbs.
A review of past research and accident databases, conduct of full-scale testing, and computer simulation and validation were conducted in an attempt t...
Portable concrete barriers (PCBs) are frequently used to shield motorists where limited deflection is desired during vehicle impacts, such as on bridg...
