§ 51.01 – Under what conditions should I develop a template sampling plan for next year?

(a)    If you have previously been using a ready-to-use sampling plan and the next report year is your mandatory sampling year;

(b)   If you have previously been using a sampling plan, but it is not based on the conditions of your service;

(c)    If you have previously been using a template sampling plan, but you must revise it for your next sampling year according to Subsection 56; or

(d)   If you previously have been using an alternative sampling plan, but would like to:

(1)   improve your sampling efficiency,

(2)   change the unit of sampling and measurement,

(3)   change the sampling structure, or

(4)   use a different sampling frequency.

§ 51.02 – Should I consider template sampling plans if I am a small system and want to sample?

(a)    You do not have to consider template sampling plans.  You may continue using ready-to-use sampling plans while you continue operate no more than 30 vehicles operated in maximum service for all modes combined.

(b)   It is likely to be in your interest to consider template sampling plans. 

(c)    If the sample size requirement is considerably smaller for template sampling plans than for ready-to-use sampling plans, the benefit is likely to be much greater than your cost from considering template sampling plans. 

§ 51.03 – Does this Manual have a companion tool that I may use?

(a)    Yes, this companion tool is an Excel template, “The NTD Sampling Template.xlsm.”

(b)   It is specifically designed for you to develop template sampling plans.

(c)    You may download a copy of this template from the NTD homepage at www.ntdprogram.gov. 

§ 51.05 – What is the scope of this template?

(a)    You may use it for any mode of transit service, such as bus (MB), that is explicitly recognized by the NTD.

(b)   You may use it for any type of service, such as directly operated (DO), that is explicitly recognized by the NTD.

(c)    You may use it with sample data in any unit of sampling and measurement.
