There should be boxes on the top of the citation, if checked for mandatory appearence, you would need to attend, though for a speeding ticket I would be shocked if that were checked. There may also be a pretrial date, as I recall there is a specific state trooper assigned to those, (if it is a State Patrol Case). You should contact the District Attorneys office, explain your situation and see if you can get some form of a reduction. Unless you feel you want to fight the ticket, otherwise you are entitled to a bench trial (possible jury if you pay the fee).
This communication does not create an attorney client relationship, and I am only providing general advice, not legal advice.
