Gillon, P.E. Re: 1725 Turnpike Road, North Andover, MA At your request, I have re-evaluated the traffic implications associated with improving the existing A.L. Prime gasoline station site by adding two double gasoline dispensers and relocating a larger C- Store at 1725 Turnpike Road (Route 114) in North Andover, Massachusetts. Based on the Institute of Transportation Engineer's Trip Generation Manual,The comparison between existing and future trips is as follows: Weekday AM Peak Hour PM Peak Hour In Out Total In Out Total Projected 2378 122 122 244 134 134 268 Existing 1586 81 81 162 89 89 178 Increase 792 41 41 82 45 45 90 Pass-By 475 25 25 50 25 25 50 New Roadway Trips 316 16 16 32 20 20 40 (additional vehicles) (1.58 16 20 Please note that in the table above, a trip is a vehicle either entering or leaving the location so that a customer who visits once is counted as two trips, one in and one out of the station, although it actually only adds one more vehicle travelling on the abutting Route 114. Also note that the above numbers are related to vehicles crossing the driveway in or out of the station. Route 114 has approximately 22,900 daily vehicles, of which about 2,000 use the road during the morning peak hour and 1,750 use the roadway during the evening peak hour. The above projected new trips constitute a Route 114 traffic count increase of only 0.7%for the average weekday total,a 0.8% increase during the morning peak hour, and a 1.1% increase during the evening peak hour. The projected numbers are based on metrics provided by the Institute of Traffic Engineers (ITE) manual, which meets the best industry practices. However, many traffic engineers question the ITE straight-line trip projection rate based on variables including convenient store square-footage or the increase in number of fueling positions.This approach does not take into account variables which have much higher impact to facility traffic but for which there is no convenient measure such as effect of nearby competitive outlets, pricing, ease of access, and brand loyalty. Demographics and competition do not change with the increase in the number of fueling positions or store size; a station that is never busy and sells little volume will not be expected to increase sales simply by doubling the number fueling positions but the ITE manual would project that sales and traffic at the station would double. i I 111 RiverStreet Gillon Associates Weymouth, IWIA 02191-2104 Telephone: (781) 589-7339 7Tr.lffic& Parking Specialists e-mail:it.gilion@comcast,.net?1 I TECHNICAL MEMORANDUM To: Anthony Guba Date: July 19, 2018 From: John T.

Re: 1725 Turnpike Road, North Andover, MA At your request, I have evaluated the traffic implications associated with improving the existing AL Prime gasoline Station site by adding two double gasoline dispensers and relocating a larger C- Store at 1.725 Turnpike Road (Route 114) in North Andover, Massachusetts (Figure 1). The existing site includes four double dispensers with eight (8) fuel positions and a convenience store totaling approximately 800 square feet(Figure 2). The proposed improvements include adding two double dispensers for a total of twelve (12) fuel positions and a larger store of 1,999 square feet(Figure 3). While the existing northerly curb cut was narrowed by almost 50 feet it was necessary to retain a wide apron for gasoline tanker trucks entering from this direction for access to the underground storage tanks. The proponent has also reduced the southerly drive by about 40 %to provide definition, improve landscape curb appeal, and enhance safety. The site does separate the existing double diesel dispensers from the regular unleaded gasoline used in most domestic vehicles but presently motorists need to jockey for access to the middle fueling positions of the three pump island if the two end pumps are occupied. The four new fueling positions on the westerly side of the site will create some breathing room for maneuverability now that the store was relocated to the southerly end of the site. Moreover, any on-site queuing at the pumps will be shifted further from Turnpike Read and will dissipate more quickly as well. Turnpike Road has one through travel lane in each direction and a single bi-direction center turn lane between the two through lanes. Turnpike Road carries approximately 22,900 vehicles per day as provided by MassDOT at counting Station ID 5130. About 2,000 vehicles are accommodated during the weekday morning peak hour and approximately 1,750 during the evening peak hour (Figure 4). The Institute of Transportation Engineer's Trip Generation Manual (10rh Edition) was used to j project the number of vehicle trips that may be generated by the combined gasoline and convenience store facility. This manual suggests that about 60 percent of trips associated with this type of land use are already on the roadway for other trip purposes such as work related. As can be seen on Figure 5, the site is expected to generate about 32 new morning peak hour trips with 16 both inbound and outbound. During the evening peak hour the site is expected to generate about 40 new peak hour trips with 20 inbound and outbound. New site generated trips were assigned similarly to the existing directional split on Turnpike Road (Figure 6). The projected total trips as projected from the ITE manual during both commuting peak hours were 9, assigned similarly to the existing Turnpike Road flow and are provided schematically on Figure 7. i f l f I 1 Ali p. m w, ��, " J '' // w.
