This paper deals with Context Sensitive Design (CSD) and contemporary approaches to geometric design that can be applied to the upgrading of Canadian highways. The paper discusses three contemporary approaches to highway design that can be incorporated with CSD. Much of the focus is on adaptable cross-sections, speed control techniques and design for 85th percentile speeds. Also of relevance is the use of variable design speeds and techniques to transition drivers between these different speed regimes. The paper concludes that the use of CSD requires peer review and the incorporation of inputs from specialists in human factors, traffic safety, operational effects of geometrics, maintenance operators, environmental sciences and tort law. In most jurisdictions, the use of CSD will require further site-specific considerations and research in the areas of crash and speed prediction modelling and in local factors relating to human factors, geomorphology and the environment.
