FHWA has released a 2013 edition of the Traffic Monitoring Guide (TMG) which provides the most up to date guidance to State highway agencies in the policies, standards, procedures, and equipment typically used in a traffic monitoring program.

The Traffic Monitoring Guide is available in the following formats:
