Even een kort stukje tekst over vangrails. Heel belangrijke stukken straatmeubilair waar je nauwelijks bij stilstaat.
A guardrail is a system designed to keep people or vehicles from (in most cases unintentionally) straying into dangerous or off-limits areas.
In traffic engineering, highway guardrail may prevent an errant vehicle from impacting roadside obstacles which may be either man-made (sign structures, culvert inlets, utility poles) or natural (trees, rock croppings), running off the road and going down a steep embankment.
A secondary objective is keeping the vehicle upright while deflected along the guardrail. The most common type of guardrail in use today is the Blocked-Out W-beam (Strong Post), as seen here.
Strong-post W-beam guardrail consists of wood posts and wood blockouts or steel posts with wood or plastic blockouts. The blockouts reduce or minimize a vehicle snagging on the posts upon impact. In addition, a blockout may be used to increase the offset of guardrail with an obstacle such as a curb.The posts' primary purpose is to maintain the height of the guardrail during the initial stages of post deflection.
Maintaining guardrail height also reduces the potential for a vehicle to vault over the guardrail upon initial impact. The posts also play a role in the amount of resistance and deflection a guardrail may experience during impact. Resistance in a strong post system results from a combination of tensile and flexural stiffness of the rail and the bending and shearing resistance of the posts. #thankyouguardrails

Heb nu 3 keer gekeken, ik zie geen vangrail in het plaatje...
