In recent years an orderly procedure for planning, designing, and evaluating urban transportation systems has evolved. Often referred to as the urban transportation planning process, this procedure requires the estimation of the amount and characteristics of traffic which will be generated by the various uses of land in the community. These estimates must apply not only for conditions pertinent to the time the traffic, land use, or other survey are conducted, but also for periods 20 to 25 years in the future. An exploratory study of the concepts and procedures used in recent transportation studies to derive non- residential trip attractions was undertaken. A large number of study reports as well as technical memoranda and other internal documents were researched. Extensive meetings with engineers and planners involved in trip generation analysis were conducted.
