Towards a checklist for credible speed limits; Development of an assessment method based on road and road environment characteristics. One of the short-term possibilities of reducing the percentage of speeding offences is to improve the credibility of speed limits. A speed limit is more credible when the limit in force conforms more to what the road user intuitively considers to be safe for the relevant road section i.e. without knowing what the actual limit is. This is determined by a broad range of road and road environment characteristics. This report describes the first steps towards a checklist with which road authorities can quickly and simply see if the current speed limit of a particular road is credible. The checklist focuses on urban roads with a speed limit of 30, 50, or 70 km/h and rural non-motorways with a speed limit of 60, 80, or 100 km/h.
