This file contains the proportion of passenger hours during which the riders were "uncomfortable" according to the Service Delivery Policy. It contains the totals across the Fall 2019 rating. High-volume Time Periods The maximum comfortable passenger-to-seat ratio for high-volume travel periods is 140%. At loads of 1 40% or less of seated capacity, all passengers are considered comfortable. No passengers are considered comfortable when the vehicle load exceeds 140% of seated capacity. Low-volume Time Periods The maximum comfortable passenger-to-seat ratio for lower-volume travel periods is 125%. At loads up to 125% of seated capacity, all passengers are considered comfortable; above 125% and up to 140% of seated capacity, seated passengers are considered comfortable; and no passengers are considered comfortable when the vehicle load exceeds 140% of seated capacity.
