Consultant, received a 1099-Misc from his "employer". I travel to their office Mon-Fri using public transport that cost over $13.00/day. Can I deduct the travel expense?

My son is a first year marketing consultant, and received a 1099-Misc for Non-Employee compensation (box 7).  He travels to their office Monday to Friday every week on public transport that cost over $13.00/day.  Can he deduct the daily travel expense by multiplying all the days that he goes into the office by the $13.00?  This adds up to be a large amount of money for the entire year.
