This study examines the pedestrian traffic changes in the chicago central business district from 1981 to 1989, dates of two major pedestrian traffic surveys. Each interviewed more than 1, 400 and counted more than 3 million pedestrians. Pedestrian flows have changed with land use changes and the growing importance of the two major train stations on the west side of downtown. Office space has increased and retailing has moved north. Some areas have experienced decliningpedestrian traffic as pedestrian traffic generation rates of downtown office space declined. Some basic characteristics of pedestrians and their traffic patterns have not changed. The stability in the daily pattern of pedestrian traffic, even when volumes rise or fall, leads to a method to estimate 10-hr pedestrian volumes. This method is proposed because it is easy to use, it requires little data, and existing milwaukee and los angeles models do not work well without recalibration.
