Road design has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Many of the basic principles for good road design were developed up to 40 years ago, and are still valid today. Although further refinements have been explored since then, there still remains uncertainty about relationships associated with design details and recent engineering innovations. Road infrastructure should be designed taking account of the same injury tolerance criteria as those developed for vehicle occupant protection and pedestrian impacts, so that roads and vehicles together provide an effective safety system.
