Ron Müller managed the traffic engineering and permitting efforts for an 865,000 square foot retail lifestyle center on Commerce Way in Plymouth, Massachusetts while employed at Greenman-Pedersen, Inc. The project required review and approval from the MEPA office, the MassDOT including a Highway Access Permit and approval of construction documents for off-site traffic improvements, and local approval from the Plymouth Planning Board and a Master Plan Special Permit from the Plymouth Zoning Board of Appeals. Due to the size of the project, Ron Müller also prepared an internal site circulation study to evaluate traffic operations at the internal intersections within the project that resulted in the installation of a traffic control signal at the main internal intersection and the construction of a bridge over the main access road connecting retail centers on both sides of the access road.
