MDM G:\Projects\814 ‐ Sudbury (Hudson Rd)\Correspondence\814 MR02 ‐ Second Response to Peer Review_Final.doc 

at  the midpoint  of  the  vehicle,  falls  within  the maximum  swept  path  of  the  ladder  truck 

presented in the AutoTurn® exhibits.  In some cases the wheel tracking (shown as a green line 

type on the exhibits) is coincident with the swept path of the vehicle bumper overhang (shown 

as a blue  line type on the exhibits).   These exhibits confirm that maximum vehicle swept path 

(including both wheel tracking and vehicle bumper overhangs) does not impact opposing travel 

lanes  and  that proposed  curb  radii  and  lane dimensions/alignment will  satisfy maneuvering 

requirements for these vehicle types.  As described under Response to Comment No. T2 below, 

additional AutoTurn®  analysis  is presented  for  additional modifications  at Peter’s Way  and 

Concord Road that also confirms that appropriate swept path area is provided at that driveway 

as well.   Reproduction of the originally submitted AutoTurn® exhibit (Figure 1 of the May 31, 

2016 memo) is included in the Attachments for reference including wheel tracking and vehicle 

overhang tracking/swept path. 

 

Measures to Reduce Potential “Cut‐Through” Traffic 

 

Comment T2: “The Applicant should  revise  the proposed modifications  to Peter’s Way  to address  the 

following  comments, which  should  also  be  reflected  in  the  revisions  to  the  fire  truck  turning  analysis 

discussed previously: 

 

 T2 (1): “Signs should be posted on Peter’s Way at Concord Road stating “Residents Only” and 

“No Outlet””.  Similar  signs  should  be  posted  on  the  northbound  exit  from  the  roundabout 

internal to the project site”. 

 

Response:    The Applicant will  include  the  suggested Residents Only  and No Outlet 

signs at Peter’s Way as suggested.   These signs are shown on  the updated Conceptual 

Access Improvement Plan  included as Exhibit 1.   Placement of these sign types within 

the project site at the roundabout are not warranted. 

 

T2  (2):  “The  proposed  gate  system  should  incorporate  an  emergency  pre‐emption  system 

(OPTICOM®) for responding emergency vehicles.” 

 

Response:  Peter’s Way,  a  private  road, will  be  designed  for  resident  use  only with 

appropriate signs as suggested by peer review above and ability to reverse direction for 

vehicles that inadvertently use this private road.  Based on input from a working session 

held with the Town the week of June 13, 2016 gated control is not proposed.
