The Traffic Administration Office, created in 2006 for the purpose of helping INDOT provide efficient and uniform traffic control for Indiana’s highway users, has several primary areas of responsibility. Among these are developing and providing guidance on the Indiana Manual on Uniform Traffic Control Devices, developing and revising numerous agency policies related to signs, signals, pavement markings, and lighting (known as Operations Memorandum), developing and revising Standard Specifications and Drawings for traffic control devices and other safety features, and providing stewardship for the agency's logo and tourist attraction sign programs. Since that time, additional duties have been added — in 2009 the office began the administration of the inspection programs for overhead sign structures and high mast lighting towers. More recently, Traffic Administration has acquired ownership of the Test Methods (evaluation procedures) and Qualified Products Lists for Portable Signals, LED Luminaires, Automated Flagger Assistance Devices, and ADA Compliant Work Zone Devices.
All of our work is done with the understanding that traffic control devices are how the roadway communicates with road users — conveying regulations, warning of potential safety issues, providing guidance — and are essential to a well-performing highway system.
