Subject: / ITS Device Maintenance
Greetings, Due to the growing ITS infrastructure and lack of expertise in-house in some areas, NCDOT is considering additional ways to operate and maintain devices to meet a standard performance level. Currently, there are no standard performance level expectations, no statewide inventory of devices, and most of the devices are being maintained in-house, with the exception of a few scattered on-call contracts. The devices are located in areas ranging from very rural to urban. The urban areas have developed the expertise to maintain devices, whereas the rural areas are using signal techs to maintain. We are interested in learning how your state has tackled this challenge, specifically:
Performance level expectations (Is it the same in all areas - rural vs. urban? Do they apply for in-house or contract maintenance? Any notable challenges? Is ITS maintenance done in-house, by contract, or combination? If by contract, is it full-service or on-call? Are the contracts done statewide, regionally, locally, or combination?
Thank you for taking the time to respond! ______Jennifer Portanova

Maryland maintains a performance goal of reviewing the traffic operations of each signalized intersection every three years. This goal is obtained by reviewing 1/3 of the signals each year. We are discussing a change to every five years (1/5 each year). It involves a critical review that results in a wide variety of upgrades, from minor work such as refreshing pavement markings, to signal timing adjustments, to complete re-design and upgrades. The analysis/reports of the signals are performed under consultant contract. We review the reports to determine the extent of upgrade work to be performed. The minor work (pavement markings, signal timing, bulb replacements) are performed in-house. Replacement signal work is performed under contract.
We also have a goal to replace signal head bulbs within 24 hours of notice. This is becoming obsolete due to our goal of replacing all signal heads with LEDs. Again, all minor signal maintenance work is performed in-house.
There is no differentiation between rural or urban for all of our performance measures and goals. Thanks and let me know if you have any questions.

Jennifer, the NJDOT primarily uses our own employees to maintain ITS equipment. The goal is 90% of DMS and cameras operational. See attached sheet for items we track. We are a little below the goal at this time because we were down to only 2 employees from 5, but we are in the process of hiring. We have a statewide ITS Maintenance Contract that we use to help when we are shorthanded or there are functions that our unit cannot undertake, like cutting loops or excavating for a fiber repair. See attached Contract Item list. Our statewide ITS database is online. Michael F. Pilsbury

Jennifer, Georgia DOT has been using performance-based contract maintenance for our interstate ITS maintenance in metro Atlanta for the last two years. We started by doing a complete assessment of the system and identifying devices that were at or near the end of their useful life. The first phase of the contract included payment for replacement of those devices. This required large expenditure of funds up front, but hopefully resulted in better prices for maintenance over the life of the contract because risk to the contractor was significantly reduced. We are now in the phase where we pay based on performance level. A payment schedule can be found on page 7 of the attached contract. We have had minor contractual issues since the contract started, and we are compiling a list of "lessons learned" for use in our next advertisement. We will be happy to share this document when it is substantially complete. I hope this information will be helpful to you and any others who may be considering performance-based maintenance contracts.
Give me a call if you have any questions or need additional information.
