I've had more than my share of tickets (most many years ago when I was younger and drove faster). I deserved almost all of them. A couple or three times I absolutely didn't deserve the ticket. But I always signed them. And I went to traffic court a couple of times when I was right... but the average citizen stands no chance in traffic court.
Did you win, lose, or draw? I don't know what the answer is to a situation where a magistrate is trying to figure out who's telling the truth and the choice is between somebody who ostensibly has no reason to lie and someone else who has a motive to lie but is actually the one telling the truth. It's an age-old quandry. Unless he or she is a complete idiot, the average judge has seen enough B.S. that the nice uniform doesn't buffalo him/her. But they've also seen a lot of average citizens who were lying their asses off. I have a buddy who's contested five cites, won four of them and got a dismissal when the cop didn't show for the other one. They weren't 'he said, she said' cites, though, so he was able to take physical evidence into court.
