Predicting the type and volume of purposeful bicycle trips. Presented at the 54th Annual Meeting of the Transportation Research Board, Washington, January 1975.

The percentage of trip makers by trip type who could make their trips by bicycle is determined. The factors affecting bicycles use are discussed. Because trips whose schedule is flexible have a greater probability of being made by bicycle, bicycle systems should not be designed to accommodate trips whose schedule is rigid, such as work and school trips.
