If you have accepted you were the driver then under the Data Protection Act you can ask for any personal information about you held by the police. That includes any recording of your movements in your car. You can do this now, before taking the matter to court. You should do so as soon as possible so you can use the information to help you check the validity of the speeding allegation made against you. This is so you can determine if there is a valid allegation for you to answer and if you wish to accept the fixed penalty offer, if made.
You could send a letter, or email, as follows to the police; “I am making a Subject Access Request under section 7(1) of the 1998 Data Protection Act that you provide me with a copy of all information you are holding with respect to the speeding allegation you have made against me. In case you should question this request, or claim exemption, I have been advised that the Information Commissioner's Office has recently ruled that I am entitled to such information at this stage of the proceedings. In this I also ask you to provide me with full information about the type and location of the measuring instrument used.”
If they still refuse then report back, or send me a PM.
