N2  - The measurement of pedestrian volumes for use in determining signal warrants or calculating accident exposure has traditionally been accomplished by manual counting. Some efforts have been directed to the development of mechanical devices and analytical modeling. None of these developments have yet enjoyed widespread success and acceptance. In an effort to reduce the costs and resources to produce manual pedestrian counts, a sampling technique was developed using expansion models to predict hourly pedestrian volumes, thus reducing manpower requirements and data collection costs. The procedure was developed from data collected in Washington, D.C., that included over 18,000 5-min pedestrian count intervals. The resulting expansion models were validated with data not used to develop the models. The models and the procedures for applying them were deemed valid. There was strong intuitive evidence that this method may be applicable in other cities even though this aspect has not yet been tested.
