About Our Business

Aldridge Transportation Consultants, LLC (ATC) is a professional service
consulting firm specializing in traffic engineering and transportation planning.
The firm was founded in 1991 by John M.W. Aldridge, PE, PTOE, AICP.  John is
a Colorado Registered Professional Engineer, a Professional Traffic
Operations Engineer, and a member of the American Institute of Certified

ATC’s client list is substantial and includes city, county and state governments
and numerous private sector developers of major residential, commercial, and
shopping center projects. Most projects are technically challenging and ATC is
proud of its reputation for resolving difficult traffic engineering and
transportation planning problems with creative and innovative design solutions.

ATC has prepared over 500 traffic impact analyses, designed over 50 traffic
signal systems, prepared several access management plans, and served in a
sub-consultant role to architectural and civil engineering firms for traffic
engineering and transportation planning support. John Aldridge has an
impressive list of major project accomplishments with responsibility as the
lead traffic engineer and/or transportation planner.

ATC is purposely maintained as a small professional service company to
provide clients with a “hands on” approach from a highly experienced
professional. We are networked, however, with other professionals in the field
of traffic engineering and transportation planning - so no job is too big for us to
handle efficiently and in a timely manner.
