In regard to the author of Acts, Luke, Wallace writes:
"Luke’s narratives include detailed and specific descriptions related to the locations, people, offices and titles within the Roman Empire. In fact, many of Luke’s claims were eventually confirmed by archaeological discoveries..."
Wallace also offers resources for those who want to learn more about the corroborating evidence for the New Testament provided by archaeology.
