I agree you really need to tell us what state this is.
In Texas, speeding tickets are a criminal matter (Class C misdemeanor) and are punishable by fine only.
This means that if you do nothing.. i.e. show up to the arraignment but don't sign anything giving up your right to a trial by jury then that's what you will get - a trial by jury. They have to.
If you do sign something waiving your right to a jury trial, you could possibly take defensive driving, ask the court for deferred adjudication, or anything else the judge wants to let you do. You could even ask him to dismiss your case.
If you do get a jury trial in Texas and the police officer doesn't show up, make a motion to the court to 'dismiss for lack of prosecution.' and it should be dismissed. If they don't dismiss it and reschedule the trial (reset it), object to the judge telling him that you showed up ready for trial and it was a great inconvenience to you (maybe you took off work, or arranged child care) and that to reset it would be a burden to you, then ask for dismissal. You'll likely get it.
If you do go to trial and get a guilty verdict, you can ask that the jury be the ones to assess punishment. Once the jury assigned a fine to me of 1 dollar. (But court costs were 128 so it was still not good).
In Texas there are certain conditions that if you were found guilty in a lower court (not a court of record) that you can appeal the guilty verdict to a higher court and you will be given a completely new trial (de novo) and start over, with the officer needing to show up all over again and do the trial all over again. (but you will need to pay an appeal bond of double the fine) - you'll get it back if found not guilty or the case is dismissed.
