This paper discusses the development of the Disabled Adult Transportation System in Edmonton, focusing on the user from two points of view: research and marketing. Three research techniques were used to determine and identify the user--incidence levels, civic census, and a registration system. Each technique is defined and described with a review of its advantages and disadvantages. The underlying philosophy of the marketing program was to involve disabled persons. This was achieved by information meetings, public meetings, and an Advisory Council that included disabled persons. The Advisory Council has met on a regular basis throughout the developmental and operational stages of the system and is considered to be central to the system./Author/
