Time-of-Day Characteristics
The following pages contain detailed time-of-day characteristics of truck trips in various locations. Time-of-day characteristics summary tables are provided both as percentage of total daily truck trips (Table F-1) and as percentage of total hourly vehicle trips on the roadway (Table F-2). The median hourly distributions are shown in Tables F-1a and F-2a.
