of TMs s,s <br /> z. <br /> Aannin Board <br /> c� <br /> 16 Great Neck Road North <br /> .wlashpee, Aassachusetts 02649 <br /> Ms. Faulkner referenced the previous calculations of where traffic was coming from, it was <br /> noted 75% from the north, and 25% from the south. <br /> Mr. Adams stated the recalculations were adjusted to represent 60% and 40%, and do their <br /> best to approximate where they travel, but it is part science and part art. In the original T&B <br /> letter from December of last year, they agreed with the distribution approach, it's not to say it <br /> was exactly right but they took input and factored in a set of analysis based on lived <br /> experience, and they provided that analysis. <br /> Mr. Tobin went through his three issues. The first point he wants to make sure they fully iron <br /> out is the efficacy of mitigation measures at the Route 28 and Shellback Way intersection. He <br /> has concerns about the curb cut right turn in, it has an impact on the Town. We confirmed it <br /> has implications for pedestrian safety given the bike path. He mentioned previously, the <br /> thought of left-hand turn lane onto Charles Street heading south on Rt. 28, and what will <br /> happen when people are swapping from the left into the right lanes right by the proposed curb <br /> cut, to avoid the backup in the left lane. Then, those people turning right off of Steeple St. <br /> creates what engineers refer to as a mixing zone. It has to be addressed, and he would like to <br /> see precise mitigation efforts for queues on Shellback Way. 50% of the time the data shows <br /> 110ft. of queing, which is short of blocking off the first commercial entrance into Deer <br /> Crossing. The next data point is the worst 5% of the time you are at 156ft. of queuing, which <br /> is clearly blocking the entrance. We have this knowledge gap between 50% and 5% of the <br /> time, at 110ft.-156ft., knowing that entrance is blocked at 135ft. It is important to note; we <br /> have had abutters raise concerns about trucks coming out and the impact that will have on <br /> queuing. The second item was about data collection and methodology, which was covered <br /> throughout the course of the evening. He would appreciate clarity from both engineers, <br /> whether there was additional analysis done on the Mashpee Rotary. There was some <br /> absence there, but based on discussions from this evening, it sounds like perhaps that's not <br /> the case. The third issue is capacity issues on side streets along Route 28. Ms. Faulkner <br /> pointed out some tables show a LOS grade of F staying an LOS grade of F but with greater <br /> degradation and in some instances an absolute failure of capacity as the ratio exceeds 100%. <br /> He will defer to the traffic engineer and Ms. Faulkner to explain those last two respective <br /> points. His points all fall under the category of mitigation regarding Route 28 and Shellback <br /> Way. (The intersection of Shellback Way, queuing on Shellback, the curb cut on Route 28, the <br /> defacto left turn lane to Charles St. and people turning off Steeple St. onto Route 28). <br /> Ms. Waygan stated the first point is pretty serious and will look to the Board engineer. Do you <br /> understand what he is saying and are there things we can do to mitigate? <br /> Mr. Lucas commented to the Route 28 and mitigation efforts, and the left turn. The mitigation <br /> presented and summarized from the analysis done at the signalized intersection at Charles St. <br /> didn't account for that left turn concern. That idea was discussed at the last meeting. What <br /> 23 <br />
