Soft thinking™ at the roadside

  • Built up verges allow cars which unexpectedly leave the carriageway to run off without hitting anything hard within the safety zone!
  • No steel posts above 89 mm within the safety zone and not in pairs!
  • Strong restrictions on the use of steel posts with shear off solutions!

Because:

Road systems should be designed based on human prerequisites. It should guard against human errors having fatal consequence and the human body should not be exposed to greater collision forces than it can tolerate. That is soft thinking.
