The development of standards for road restraint systems

Abstract

The article discusses requirements for road restraint systems, gives recommendations for their classification, formulates the requirements for layout of cameras for recording tests, proposes a method for determining the values of the dynamic deflection and the working width of the road barriers. This work proposes a classification of road barriers; gives the estimates of the influence of tolerances in weight and collision speed of a vehicle in the field tests of road barriers on the values of dynamic deflection and the working width; introduces the concept of category for the dynamic deflection and working width of a barrier; supplements the testing methods for different types of road barriers.
