77 A P P E N D I X D Given that the NCHRP Project 17-56 data collection consisted of short (1-hour or 2-hour) pedestrian counts, it was necessary during the analysis phase to convert these short counts into day-long pedestrian volumes.

78 Development of Crash Modification Factors for Uncontrolled Pedestrian Crossing Treatments The factors presented in Table D-2 are general factors for any count taken, regardless of time of year. They are however weekday-only factors, since all pedestrian counts done by the City of Charlotte were performed on weekdays only.

Analysis of Charlotte Pedestrian Volumes to Determine Method for Adjusting Pedestrian Volume Counts 79 Adjusting Pedestrian Volume through the Years Another question for the analysis is if and how pedestrian volumes in past years should be estimated based on present day counts. Essentially, most treatment and comparison sites included in NCHRP Project 17-56 only have pedestrian volume from 1 year -- typically 2014 when the field data collection was done.
