PIARC Catalogue of design safety problems and potential countermeasures

This catalogue presents a set of commonly design errors and suggests a range of measures to overcome them; it also gives an indication of the comparative countermeasure costs to facilitate prioritisation of the work. The catalogue can be used both as a proactive safety tool to ensure the design faults do not arise in the first place, or a reactive safety tool to assist in designing cost-effective countermeasures where problems already exist on the road network.

The situations considered are organized within 8 groups:

  1. Function
  2. Cross Section
  3. Alignment
  4. Intersections
  5. Public and Private Services
  6. Vulnerable Road Users
  7. Traffic Signing and marking
  8. Roadside Features

For each case, a sheet is presented with several illustrations.
