Urbicus was a Roman cognomen, meaning "of the city" or "civic".
It was borne by several Romans from the Imperial era:
Pompeius Urbicus, knight that lived in Emperor Claudius’ reign
Quintus Lollius Urbicus, 2nd-century Roman governor of Britain and prefect of Rome.
Quintus Petronius Urbicus, prefect of Cohors IV Gallorum equitata, around 230 CE
Aggenus Urbicus, Roman technical writer who probably lived in the late 4th century.
