Traffic Simulation Study
REF:822-Mem10-TSS
DATE:September 26, 2013
Traffic Simulation Study (TTS)
In order to respond to the concerns of the Planning Board regarding the Simulation of Traffic in
the parking lot of the proposed Daycare facility, Precision Data Industries, LLC (PDI) was
commissioned to complete a Traffic Simulation Study (TSS) of the parking lot for the proposed
Daycare facility under the proposed operating conditions. To complete this study, several
drivers were hired to drive into the parking lot and simulate the dropping-off of a young child at
the Daycare facility between 7 and 9 AM. This Study was completed on Wednesday September
25, 2013. All drivers were instructed to arrive/depart to/from the site in a pattern that would
mirror 5 vehicle arrivals every 15 minutes. The five vehicle arrival rate was chosen to match the
recommendation from the town’s Traffic Peer Review Consultant, Vanasse & Associates, Inc.
(VAI). VAI’s letter dated September 10, 2013 noted “Implementing an active drop-off/pick-up
management plan such that no more than five (5) children arrive in a 15-minute period
would limit the traffic and parking demands to a level that is commensurate with the
available parking supply afforded by the Project site and allow sufficient time for vehicles
to exit in the context of queuing at the Turnpike Street/Peters Street intersection.” The
proponent is willing to accept this condition as part of an overall approval of the proposed
project. For the purpose of this study, we have interpreted the 5 children per 15-minute arrival
rate to mean five vehicles per 15-minutes since the study assumes no carpooling and no
siblings arriving in one vehicle. The five vehicle arrival rate was developed such that vehicles
#1 & #2 would arrive at approximately 7:00 AM, vehicles #3 & #4 would arrive at approximately
7:05 AM and vehicle #5 would arrive at approximately 7:10 AM, creating a pattern of 2, 2 and 1
vehicle arrivals every 5 minutes starting at 7:00 AM. This 2, 2 and 1 vehicle arrival pattern was
repeated every 15 minutes starting at, 7:15 AM, 7:30 AM, 7:45 AM, etc. The actual Traffic
Simulation Study arrival schedule, Table 1, Traffic Simulation Study Instructions, is reproduced
in the appendix of this Memorandum.

The Traffic Simulation Study drivers were given three different routes to approach and depart
the site to simulate the projected traffic volumes at the site driveway and parking lot. The
project traffic volumes are similar to the DJK Associates, Inc. Memorandum dated August 14,
2013. The actual projected traffic volumes are shown in Figure 1 2013 Existing Plus Site
Generated Peak Hour Traffic Volumes in the appendix of this Memorandum. Note the existing
traffic volumes shown on Figure 1 are from the August 14, 2013 DJK Associates, Inc
Memorandum and not from the Traffic Simulation Study. The three different
approach/departure routes are described below and they are consistent with the North Andover
Police Department recommendation that the exit drive be signed for RIGHT TURNS ONLY:
Red Route – Vehicle/Driver #1 was assigned to enter the site from east of the Salem
Turnpike/Peters Street intersection and travel westbound along Peters Street and turn
left into the site. The departure route was a right turn out of the Site Drive and
eastbound through the Peters Street/Salem Turnpike intersection.
Blue Route – Vehicle/Drivers #2 & #4 were assigned to enter the site from Peters Street
eastbound and turn right into the site. The departure route was a right turn out of the
site drive and a right turn at the Peters Street/Salem Turnpike intersection.
Green Route – Vehicle Driver #3 was assigned to enter the site from Salem Turnpike
northbound, turn left at the signalized intersection and then turn left into the site (i.e.
double lefts). The departure route was a right out of the Site Drive and a right turn at the
Peters Street/Salem Turnpike intersection.
Traffic Simulation Study Video
The TSS was recorded by a Video Recorder camera located immediately west of the site and it
recorded the entire parking lot between 7 and 9 AM, Wednesday, September 25, 2013. The
Traffic Simulation Study Video was conducted without the benefit of the proposed DO NOT
BLOCK INTERSECTION sign (MUTCD reference # R10-7) placed along Peters Street in
advance of the Site Drive and the proposed DO NOT BLOCK pavement markings on Peters
Street in the eastbound lane adjacent to the Site Drive. The video files have been separated
into two files with one file “212593_h264_0.mp4” showing the 7 to 8 AM time period and the
other file, “212593_h264_1.mp4” showing the 8 to 9 AM time period. In order to view the files,
follow the instructions below:

6. Choose either file “212593_h264_0.mp4” for the 9/25/13 7:00 to 7:59 AM video or file
“212593_h264_1.mp4” for the 9/25/13 8:00 to 8:59 AM video.

Parking Accumulation Study
The Parking Accumulation Study was derived from the TSS Video so that one could observe the
maximum on-site parking demand during a specific time period as opposed to observing the
entire 2 hour video. Table 2, Traffic Simulation/Parking Accumulation Study as reproduced in
the appendix of this Memorandum presents the results of the Study in Tabular format. The
Average Parking Duration for all 39 Parent Vehicles was nearly 2 minutes (1:47). Please note
that the 39 parent vehicles include no carpooling, no siblings in one vehicle, full attendance and
no all arrivals occurring after 9 AM. The on-site peak parking demand varied according to the
number of staff vehicles parked on-site. For example, when there was one staff vehicle parked
on-site, the peak parking demand was 3 vehicles, 1 staff vehicle plus 2 parent vehicles. When
there were two staff vehicles parked on-site, the peak parking demand was 4 vehicles, 2 staff
vehicles plus 2 parents’ vehicles. When there were three staff vehicles parked on-site, the peak
parking demand was 5 vehicles, 3 staff vehicles plus 2 parent vehicles. When there were four
staff vehicles parked on-site, the peak parking demand was 6 vehicles, 4 staff vehicles plus 2
parents’ vehicles. The reserved parking supply during each time period would vary from 8, 7, 6
and 5 spaces, respectively. These reserved spaces could be used if a parent arrives early or
late to the Daycare facility.
The peak parking demand first occurred at 8:30:15 AM and occurred three other times for short
durations up to 8:52:12 AM. To review the peak parking demand go the video file
“212593_h264_1.mp4” and move the time slider to around 30:00. A review of a portion of this
time period would provide an indication of how the site would operate during peak parking
demand periods. During this period, there is a reserve capacity of 5 spaces (including 1 HP
space).
