Pursuant to Sections 14-311 and 14-311c of the Connecticut General Statutes, major traffic generators (MTG) are regulated as to their traffic impact on the state highway system in Connecticut by the Office of the State Traffic Administration (OSTA).  A MTG is defined by Section 14-312-1 of the OSTA regulations as any development of 100,000 square feet or more of gross floor area or 200 or more parking spaces.  The OSTA authority under these statutes applies to new MTGs as well as expansions or land use changes to those already in existence.  However, entirely residential developments of 100 units or less are exempt from OSTA regulation under these statutes.  The regulation of MTGs by the OSTA is accomplished via either an Administrative Decision (AD) or certification process (Certificate).
