During the testing, various data collection sources were used to measure and evaluate the UTT system. Each of the carrier's dispatchers maintained a manual data collection log in bound serialized books for accurate and timely collection of data. They completed the manual logs as they performed their daily dispatch activities. A minimum of one dispatcher at each carrier location was asked to complete the log for their assigned trailers. These were used for trailers with and without the UTT system.
The Manual Log instructions for the dispatchers were as follows:
Instructions:
- Data entry errors are expected. Never erase entries. Correct errors by putting a single line
through an error: Error occurred here.
- Record occurrences when the expected result occurred as well as when the unexpected result
occurred. They are equally important.
- Retain and return all notebooks including ones with coffee and food stains.
- Never remove a page from the notebook even if it has stains on it.
Please write legibly since someone will type your results in for analysis. This includes initials.
If it is impossible to retain a page or notebook copy the pages so we can see them.
A sample of a filled in daily Manual Log follows.
