I'm assuming you want a database or spreadsheet of traffic citations, and not copies of all the citations so that you can build a database yourself.
Assuming that's correct, and assuming that such a database exists, the answer is yes, you may access that. There may be some data that the police are able to pull out, but you are generally entitled to records in the format in which they exist.
So I would request the database, which probably exists if you're dealing with a jurisdiction of more than 12 people.
See, Farrell v. City of Detroit, 209 Mich. App. 7, 530 N.W.2d 105 (1995) ("In Michigan, computer records constitute public records subject to disclosure under the FOIA"); Payne v. Grand Rapids Police Chief, 178 Mich. App. 193, 443 N.W.2d 481 (1989) (plaintiff entitled to copy of tape recording of 911 emergency calls, even where city offered to provide transcript of tape); but see, Lapeer County Abstract & Title v. Lapeer County Register of Deeds, 264 Mich. App. 167, 691 N.W.2d 11 (2004) (public bodies are not required by the FOIA to provide microfilm copies rather than paper copies of the records at issue, even when the public body keeps the records on mircrofilm). See also Mich. Comp. Laws Ann. § 15.232(f) (software — which is not a public record — excludes "computer-stored information or data, or a field name if disclosure of that field name does not violate a software license.")
