The objective of this study was to develop guidelines for the use of guardrail on low-volume roads (LVR) in Kansas according to safety and cost effectiveness. LVR are generally defined as roads with less than or equal to average daily traffic (ADT), although many LVR's have much lower ADT's. It should be noted that the term 'guardrail' means some sort of restraining device to keep errant vehicles that leave the roadway from crashing into a more dangerous roadside environment. Roadside is defined as the area beyond the traveled way and the shoulder (if any) of the roadway itself. A comprehensive review of the research literature was conducted to explore and gather information of the use of guardrail on LVR according to safety and cost effectiveness. The purpose of this information search was to identify the general elements used to determine the need for guardrail on LVR and to review any specific guidelines already in use by other states. The ROADSIDE Computer Program was used to develop guidelines to determine whether guardrail is needed on fill embankments and for shielding the roadside obstacles on secondary roads.
