We have more than 90 percent of the signals across the state connected and are in the process of standing up the new ATSPM version 5. If it works well, we may move away from many of our custom developments to the new version. We hope to make this move in late spring to early summer 2025. Yes. Row 11: Iowa DOT; Blank; No. Row 12: Kansas DOT; We don’t have direct experience at the DOT level with ATSPMs technologies; No. Row 13: Kentucky DOT; Blank; No. Row 14: Louisiana DOT and D; costs keep rising, so with different contracts, need to adapt to the use of new devices; No. Row 15: Maine DOT; Blank; Yes. Row 16: Maryland DOT; We have migrated toward INRIX because there is no hardware or integration. In practice, INRIX is used with other resources. We frequently use the ATMS to watch the intersection remotely and pull logs. We also refer to the Chart website to see if there are construction or incidents. The only disadvantage of INRIX is that the data is delayed. We have also used INRIX extensively for adaptive before or after studies. It is more granular and less expensive than other data sources. Other than INRIX, there are very few S P M intersections. Since No-traffic is a preferred detection system, its number will increase in the near future; Yes. Row 17: Massachusetts DOT; MassDOT is just beginning to implement ATSPMs at signals across the state. The biggest hurdle is getting District buy-in (MassDOT’s Districts operate and maintain traffic signals) and having field staff available to make changes that are identified through the use of ATSPMs; No. Row 18: Michigan DOT; Blank; No. Row 19: Minnesota DOT; Blank; Yes. Row 20: Missouri DOT; My responses do not represent MoDOT as a whole, only the Southwest District for which I am responsible; No. Row 21: Montana DOT; ATSPM is still very new for us in M T, but we are excited about what we’ve seen so far and look forward to learning how ATSPM fits into or changes our traditional approaches to traffic signal operations and maintenance; No. Row 22: Nebraska DOT; Blank; No. Row 23: Nevada DOT; Blank; No. Row 24: New Hampshire DOT; Blank; No. Row 25: New Jersey DOT; Blank; No. Row 26: New Mexico DOT; The City of Albuquerque in New Mexico has used ATSPMs. I believe their use is limited to a few corridors and a few specific measures; No. Row 27: New York DOT; We are only just beginning, doing our first pilot or demo corridor now. So we do not have a lot to offer to date. But the plan is that for our next central signal management software to include ATSPMs; Yes. Row 28: North Caroline DOT; Blank; Yes. Row 29: North Dakota DOT; More federal guidance and determination of minimum or maximum thresholds that should be maintained would be helpful; Yes. Row 30: Ohio DOT; Answers in the last portion directed to Traditional ATSPMs and not probe-based ATSPMs; Yes.

The column headers of the table are 1. Agency; 36. Please share any additional comments or insights regarding your DOT’s experience with ATSPMs technologies; 37. Interested in participating in a follow-up interview?. The data given in the table row-wise is as follows: Row 31: Oregon DOT; Blank; No. Row 32: Pennsylvania DOT; Blank; Yes. Row 33: South Dakota DOT; The lack of a TMC and the lack of any staff trained in signal maintenance make it difficult to plan for use of ATSPMs. We also do not have any corridors with a large number of signals; No. Row 34: Tennessee DOT; None; No. Row 35: Texas DOT; Blank; No. Row 36: Utah DOT; Blank; Yes. Row 37: Vermont AoT; We have reached out to a Consultant to assist in the implementation of the new UDOT source code. Looking forward to that implementation; Yes. Row 38: Virginia DOT; Blank; Yes. Row 39: Washington DOT; WSDOT’s experience has been that adding the physical infrastructure needed to collect applicable data seems to be the biggest hurdle to the implementation of ATSPMs on a broad basis. Staff and central software have come along enough that operation and utilization are not a substantial concern; No. Row 40: West Virginia DOT; Blank; No. Row 41: Wisconsin DOT; Our DOT is split into 5 regions, some regions have more FTEs than others and are able to use ATSPMs to a greater degree than others; No. Row 42: Wyoming DOT; Blank; Yes.
