§ 79.01 – How should I estimate the annual total of my service-consumed data?

(a)    If your sampling plan is not based on service grouping, you should multiply your sample average for the entire sample with the annual total of your corresponding expansion factor to get an estimate of the annual total.

(b)   If your sampling plan is based on service grouping, you should take a two-step approach:

(1)   Multiply your sample average with your corresponding expansion factor for each group, and

(2)   Sum the above products across all groups to get your annual total.

§ 79.03 – How should I estimate average daily of service-consumed data by type of service days?

(a)    If you operate your service only on weekdays, all you need to do is to divide your estimated annual total by the number of typical weekday days of service.

(b)   If you operate your service on Saturdays, Sundays, or both as well, you should take the following two steps:

(1)   Multiply your sample average(s) for each type of service days with the corresponding expansion factor to get the annual total for each type of service days.

(2)   Divide the annual total for each type of service days by the corresponding number of typical days for each type of service days.

§ 79.05 – How should I estimate annual total UPT for each weekday period for commuter rail, heavy rail, and light rail?

(a)    For each of the weekday periods, you should simply multiply the sample average UPT you have calculated for that period by the corresponding expansion factor to get an estimate of the annual total UPT for that weekday period.
