Abstract

In the netherlands the institute for road safety research carried out research into the most suitable crash barriers for soft soil and for bridges. Based on a number of requirements, the research resulted in a series of structures that provide optimum protection in soft soil and on bridges under various conditions. The barriers comprise in principle a horizontal beam consisting of 2 w-shaped rails and spacers every 1.33 m, provided if necessary with diagonal bars, and of posts with various structural characteristics. On this basis, the netherlands authorities issued provisional guidenlines for crash barriers in soft soil and on bridges on and over expressways. These are now being used generally on national highways. /author/
