Abstract:

The installation of guardrails in Japan is conducted according to the Guideline of Guard Fences (October 1972) and has served to prevent or alleviate accidents around the country by keeping vehicles from leaving the road. However, since the guideline was first promulgated, traffic characteristics in Japan have changed considerably: the total extension of national expressways is much longer, the performance of vehicles has been improved dramatically, traffic on national expressways is faster, and vehicles are larger. Consequently, the severity of a guardrail collision tends to be much higher than before and this trend is expected to continue in coming years. For this and similar reasons, a number of investigations and experiments were carried out in 1990 and 1991 to develop new types of guardrails for highways. This paper focuses on a design of guardrails for high-speed impacts that satisfies demands exceeding those specified in the current guideline. A basic design for a guardrail capable of withstanding an impact of 20 degrees by a 20,000-kg truck running at 100 km/hr is described.
