In doing real <br /> quick math, the average is most likely 7 crashes. That doesn't necessarily indicate there is an <br /> issue,just the crash average. <br /> Mr. Tobin asked him to confirm with his professional judgement that at this location it's <br /> approximately 3.4 below the state average. Also, when figuring state averages, does that also <br /> includes major cities? <br /> Mr. Adams stated if there were 2-3 additional crashes each year, the number of crashes at <br /> this site would be at or around the state average of crashes for a signalized intersection. He <br /> stated the calculations do not necessarily include Boston, as they are hands off with <br /> MassDOT and crash data. It does include every other municipality, such as Worcester. <br /> Mr. Lucas clarified the district and statewide averages relate to the crash rate at this <br /> intersection, based on 4.6 crashes per year, and the volume is 0.66, which correlates to the <br /> 0.75 for the district average and 0.78 for statewide. If you take the .75 figure for the district <br /> and divide by .66, that is 1.136, then multiply that by 4.6, which is the crashes per year, and <br /> you would get 5.22 crashes, and that is the comparison calculated based on volume. <br /> Mr. Tobin stated it is almost at the state average based on volume of traffic. He asked about <br /> the 4.6 and 0.66 number being based on what type of conditions? <br /> Mr. Adams stated everything is based on existing volume. <br /> Mr. Lucas wanted to circle back to the outlier year with 11 individual crashes, the only thing he <br /> would've liked to see was some additional analysis alluding to why it was so different. What <br /> do those crashes tell us? The following year were 5 crashes, he truly believes it is an outlier. <br /> Ms. Waygan would like to move on to capacity analysis. <br /> Mr. Adams referred to comment 17, which was looking for additional information about vehicle <br /> queue lengths, the most recent comment asked about level of service and queue summaries <br /> for the Mashpee Rotary. They provided that information in their original traffic impact study, <br /> reviewed by T&B and the Commission with no specific comments about that traffic analysis. <br /> The Mashpee Rotary as we know it to be now has operational issues. There is some planned <br /> improvement project that would be funded and orchestrated by MassDOT. During discussions <br /> with the Commission, the project team has agreed to implement short-term safety and <br /> operational improvements, again requiring approval by MassDOT, but his project team would <br /> like to work with Mashpee and MassDOT, to input what they can now, ahead of the major <br /> project. Their original analysis shows the Trader Joes project does not have significant impact <br /> 11 <br />
