16 Great Neck Road North <br />Mash pee, J4assachusetts 02649 <br />days. They looked at the commuter hours between 7:OOa.m.-9:OOa.m. and 4:OOp.m.-6:OOp.m. A <br />24- hour flow profile allows validation of peak traffic. Peak morning is 7:15-8:15a.m. and peak <br />evening commute is 4:15p.m.-5:15p.m. The volume under average conditions is 10,775 <br />vehicles a day. Peak summer it grows another 3,000. Regarding safety and the speed of traffic, <br />we want to make sure there is no congestive conditions that would cause speeds to lower in <br />summer. There were 22,000 vehicles over that period of time and the majority or 85% traveled <br />at or below 45 miles, it was between 42-43 miles per hour. They want to see that speed close to <br />the posted speed limit when they make recommendations. <br />The look at the motor vehicle crashes on MassDOT, they collect data and publish it for safety <br />assessments. They consider 5 years of crash data, 2016-2020 had no high crash locations. <br />Echo Road had five crashes, 3 were resulted in property damages, 2 in personal injuries, and <br />no fatalities. Safety as it relates averages to one crash per year, so it is not considered a high <br />crash location. They look at a 7 year impact plan to allow for this Board to approve, build the <br />project, and generate it to the road network. The Town Planner identifies projects in the area <br />that are not yet constructed. A 1 % growth rate is standard. <br />This area is proportionately zoned, one of the advantages in this area is the similar layout and <br />similar lot sizes. The Assessor's Office looks at building sizes and types of buildings, the size of <br />the buildings are 9,OOOs.f. on average. If there are 9 lots each at 10,OOOs.f. which is 90,OOOs.f. <br />of building area, that is consistent with what is seen. In this area there are bays and workers <br />come in with a truck and pick up supplies then leave for the day and come back in the evening. <br />There is a small office area and a specialty trade contractor. If you know the type of land use <br />and what size, they can look at data published by transportation engineers. A Specialty Trade <br />Contractor usage found those numbers to be close on a per thousand square foot basis along <br />with the traffic that is generated. Based on the numbers, this project would generate 884 vehicle <br />trips on a daily basis. 442 vehicles would enter and exit. In peak hours during the one hour <br />period in the morning the subdivision would produce 149 vehicle trips. There would be 111 <br />vehicles entering and 38 exiting. In the evening hour there would be 174 vehicles total, with 56 <br />entering and 118 exiting. The majority of cars will take a left to enter and right to exit. <br />Ms. Faulkner would like to know about that level of service and whether it will be very little delay <br />or over capacity and she would like for him to mention road names. <br />Mr. Dirk stated there is a limit of acceptable traffic. Under an average month, the flow of traffic <br />exiting Echo Road at Rt. 130 is a single lane, making a left or right turn has the same level of <br />delay. Leaving the project, the delay is less than 10 seconds. In the evening there is a one and <br />two second delay which is under the average. In the peak of summer, exiting Echo Rd. in the <br />evening time, delays now increase over capacity because of the volume of cars along Rt. 130. <br />Without the project, the cue is 5 vehicles deep, with the project the cue rises to 6 vehicles.
