Controversy Regarding Guardrail Length of Need CalculationsDonoughe, Kelly M
CRITICAL HEIGHT OF EMBANKMENT AND STEEPNESS OF FILL SLOPE WERE THE CRITICAL FACTORS IN ASSESSING EMBANKMENT NEED FOR GUARDRAILS. DIMENSIONED LOCATIONS, UNIFORM CLEARANCE TO ROADSIDE OBSTACLES, END ANCHORAGE, APPROACH-END TREATMENT, MINIMUM LENGTH OF INSTALLATION, AND TREATMENT OF STRUCTURES WERE ANALYZED ...
(a) The points where the need for a road safety barrier system begins and ends (length of need). (b) Minimum transverse offset required from the edge of the adjacent traffic lane. (c) Allowable dynamic deflection and working width restrictions. ...

Each of the first number of anchor posts secures an end of a respective cable. Each anchor post is operable to release the respective cable secured by the anchor post upon a vehicle impact to the anchor post. The system may include a length of need section that includes a plurality of ...
Terminals also introduce tensile and flexural strength necessary to ensure redirection performance of the length-of-need section. Because the road conditions differ and therefor the road guardrail end is divided into a variety of styles to accommodate different types of roads. Depending on the ...
@Brenda: Guard rails need to be weakly fastened to the posts. If not, the posts will pull the rail down under the car when the car pushes the rail. Depending on whether or not the ground is wet, muddy, frozen, or sandy, the ease with which posts can be extracted will vary greatly...
