§ 73.01 – What expansion factor should I use for non-scheduled service?

(a)    You should use your 100% count of vehicle days as the expansion factor.

(b)   For estimating annual total PMT and UPT:

(1)   Use annual total count of vehicle days if your sampling plan is not based on grouping.

(2)   Use annual total count of vehicle days by group if your sampling plan is based on grouping.

(c)    For estimating average daily PMT and UPT by type of service days, use annual total count of vehicle days by type of service days.

§ 73.03 – What sample average should I use for non-scheduled service?

(a)    You must use the ratio of sample total PMT over sample total vehicle days as the sample average to estimate PMT.

(b)   You must use the ratio of sample total UPT over sample total vehicle days as the sample average to estimate UPT.

(c)    For estimating annual total PMT and UPT:

(1)   Use the sample averages for the entire sample if you do not group your service.

(2)   Use the sample averages for each group if your sampling plan is based on grouping.

(d)   For estimating average daily PMT and UPT by type of service days, use the sample averages by type of service days.  If your sample happens not to include any vehicle-days for a particular day type (e.g. Saturday), use the sample average for the entire sample. 

§ 73.05 – How do I determine annual vehicle days actually operated for non-scheduled services?

(a)    You should use a spreadsheet or some other mechanism to record the daily number of passengers carried by individual vehicles in your fleet for an entire year. 

(b)   Figure 73.01 shows an example of such a spreadsheet with the following assumptions:

(1)   your fiscal year runs from July 1 through June 30,

(2)   you operate every day, and

(3)   your fleet has 100 vehicles. 

(c)    Once you have such a spreadsheet, you can easily determine the daily number of vehicles operated by type of service days in two steps:

(1)   For any one operating date, count the number of vehicles in the fleet that carried at least one passenger on that date.

(2)   Summarize the daily number of vehicles operated by type of service days.

(d)    You can also use such a spreadsheet to determine the number of vehicles operated for each group if your sampling plan is based on service grouping.
