The Transportation Advisory Board (TAB) met on Thursday, August 7, 2025, at 7:00 PM in the Council Chambers of Naperville City Hall. All nine members were present: Scott Hurley, Michael Krzywinski, Nigel Neibel, James Webb, Sarah Rose, Andrea Nair, Brian Laird, Allison Longenbaugh, and Orhan Ulger (new member). The meeting covered several routine approvals, a major update to the City's Road Improvement Plan, parking and traffic regulation recommendations, and board member training.
Um we will try to pause and ask for questions, but feel free to interrupt us as well. But we're excited to be here this evening. As Andy mentioned, we're gonna walk through the methodology and findings for the year 2050 traffic projections. We'll highlight uh anticipated operational conditions for intersections and roadway segments throughout the city, and then we'll present the preliminary list of improvements for your review and discussion, and then kind of talk through next steps. Sorry, this is looking a little off. There we go. Um, really quickly, a brief overview for a reminder for those that weren't here in May, and and just a refresh for the rest of us. Um, the purpose of the road improvement plan is to evaluate intersection and roadway segments under the city's jurisdiction. We presented in May a review of existing traffic conditions. Um again today we're gonna talk through future conditions, your 2050, and then the ultimate output or purpose of the RIP that will refer to it as the RIP throughout the presentation, so bear with me. But the RIP will identify capacity driven improvements. And we'll talk through other components that are considered when we define those improvements, but this is a capacity driven plan. The improvements that are defined in the road improvement plan will ultimately inform the city's capital improvement plan that is reviewed annually to define uh implementation priorities for the improvements included in the RIP. And then I want to highlight and we'll come back to this at the end of the presentation. But as you all know, as we discussed in May, and we'll revisit here briefly. Um this has been an iterative planning process. We solicited feedback from the community uh to inform the road improvement plan. And as these projects move forward through the city's capital improvement plan, there will be future opportunities for public improvement as these projects move forward for design and the construction. So I just want to make sure that that stays top of mind. So, really quick, a quick revisit of existing conditions. This is a very data-driven process. The analysis included 162 intersections, um, most of which are signalized. We did also take a look at unsignalized intersections, and then over 175 roadway segments were evaluated. The data used for the analysis, the baseline data for existing conditions, uh, is largely based on data from the city and IDOT. In certain situations where that data was not readily available, we did use replica. I want to emphasize no data from your 2020 2021 was none of that was referenced for this analysis. We re-realized COVID heavily influenced traffic patterns, and therefore that data was not referenced. And then we did obtain signal timing data from the three agencies that have signals under the study network. As I mentioned, public input is a large component of this planning process. We previously held a public open house to solicit input on the existing conditions to identify opportunities for potential improvements that we may not realize through just review of an analysis file. Um, and then we did, I think we all we shared at the last meeting, we did have an online tool to solicit public input input that generated almost 500 comments. I won't go through this again, but happy to answer any questions tonight regarding the public input. So since we met last time, I want to note um I'll figure this out eventually, I apologize. Um I want to note uh since we last discussed this project, IDOT has released new existing data. Um previously we were referencing year 2022 and your 2023 existing data. IDOT released 2024 data since we last chatted. So we have subsequently updated the existing conditions analysis to reflect available year 2024 data, um, which again kind of gets us further removed from any COVID influence. So the data set is largely your 2023 or 2024, some 2022 from the city. So based on the revised IDOT data that is specific to segments, I should have said segment data from IDOT was the analysis was updated. So the segment analysis has been updated to reflect the newly released year 2024 data. This did not impact the intersection analysis in any way. The intersection analysis was previously referencing most recent available data not from IDOT. The intersection analysis is largely based on data from the city and other private traffic studies in the area. So we did update the capacity analysis for the roadway segments throughout the city, largely did not materially change the conclusions, but again, wanted to make sure that we were operating from the most current baseline data. The other thing I wanted to highlight, and I believe this was touched upon in our last meeting, is as a part of our review of operational conditions at the intersections and roadway segments. We did review the crash data. High level based on a review of that crash data. The most common crash types at the study intersections are listed on the screen, front to rear, cross movement, and side swipe. And so what we did is we evaluated the capacity improvements at all of the intersections and segments. We took a look at the benefits that those capacity driven improvements would have on safety.
