Where a Ticket Written in Northbrook Goes
Tickets in Northbrook go to the Circuit Court of Cook County. A paid ticket, a dismissal and a trial all end up in that court's records.

Illinois has no single public index of every trial court case; each court's records are looked up through that court.
Who Writes the Tickets in Northbrook
The Cook County Sheriff's Office and the agency that reports for Northbrook (filed by the FBI as Northbrook Police Department) write the traffic tickets in and around Northbrook.
The FBI's agency list also places 14 campus police departments and 15 other agencies in Cook County (the arrest records guide names each one).
The Elgin Police Department, the Buffalo Grove Police Department, the Deerfield Police Department and eight more are each listed by the FBI across several counties including Cook County, so their arrests are not broken out for Cook County here.
The Driving Record and the Illinois Secretary of State
The driving record is a separate document from the court file. It is kept by the Illinois Secretary of State, which adds each conviction the court reports and handles suspensions; the court does not issue driving records.
Paying a ticket is a conviction, reported to the Illinois Secretary of State like any other; contesting it means a plea of not guilty entered with the court by the date on the ticket.
A DUI is a criminal charge rather than a ticket, with its own license case before the Secretary of State (see Northbrook DUI).
