Confidence Level for Microwave Detector 1

[TrafficEng]

I don't know if this is the forum for such a question, if not please direct me to one better. Thank you.
I studied some statistics in my electrical engineering and physics classes but not enough to know or cover what "95% confidence level" is and how to apply it.
I need help for the following task:
Our traffic department needs to determine the "95% confidence level" of a microwave detector. It will be installed at a city intersection with in-the-street magnetic loops to detect cars approaching or waiting for the traffic light to change. The point is to determine whether or not the microwave detector is reliable enough under conditions of rain, fog, heat, cold, day or night conditions to replace expensive in-the-street loops. The microwave detector will be aimed at a lane that has a loop for its evaluation and the counts of the microwave detector compared to the loop counts. My boss needs to know how many vehicle counts are required to get this "95% confidence." The loop detectors will count all vehicles while the microwave detector may or may not detect all vehicles under all the above conditions.
Thank you in advance for any help.

You need to clarify what the 95% confidence level applies to, e.g., what is its context. One scenario is relatively inexpensive, the other is quite expensive.

Thank you, IRstuff. I'll repost it at 962.
What I wrote is all I have. I figured I'd have to work out some sort of scenario myself. Could you tell me what you had in mind that is relatively inexpensive and also the quite expensive?
Thanks again, Alan
