A second design philosophy that must be highlighted is the "Forgiving Roadside". This is simply the requirement that the roadside environment Chapter 1 describes the special types of roadside obstacles and provides criteria that can be used to determine if these objects are hazardous or not. Preliminary guidelines on tunnel design and safety standards, including risk analysis were prepared in 2005. RABT Guidelines for the Equipment and Operation of Road Tunnels (Richtlinien fur die Ausstattung und den Betrieb von Strassentunneln). These Guidelines aim to ensure new roads are safe whilst, at the same time, ensuring new developments also provide transport facilities that For Development outwith the scope of Designing Streets, for example where high traffic volumes or speeds are anticipated or where development is Haul Road Design Guidelines.
