Direct answer

Vehicle barrier system is a defined term in the International Building Code (IBC) 2009, in Structural Design. The code's own words are: “A system of building components near open sides of a garage floor or ramp or building walls that act as restraints for vehicles.” No other I-Code in this corpus defines it, so the IBC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Structural Design (IBC 2009), Definitions (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

What is a vehicle barrier system?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Structural Design: “A system of building components near open sides of a garage floor or ramp or building walls that act as restraints for vehicles.” It is defined in IBC 2009.
