Re: Rio Road Multi -Family (aka Parkway Place) — Traffic Impact Analysis
Review #2
Dear Mr. McDermott:
The Department of Transportation, Charlottesville Residency Transportation & Land Use
Section, as well as the Culpeper District Traffic Engineering Section, has reviewed the above
referenced plan as submitted by Ramey Kemp & Associates, dated 6 June 2019, and offers the
following comments:
1. For the two signalized intersections of John Warner Parkway/Rio Road and Rio
Road/Pen Park Road:
• The clearance interval and signal timings for all Synchro existing models to not
match the existing. Please obtain the existing conditions from Staunton TOC and
revise the analysis and reports accordingly.
• Please use the default value of (0) for the lost time adjustment (-2 used).
• Pedestrian phases for the Rio Rd./John Warner Parkway signal are missing from
all Synchro models. Please obtain the correct timing from Staunton TOC and
revise the analysis accordingly.
2. The TIA included Synchro reports for the signalized intersections and HCS reports for
un-signalized intersections (with the exception of the Dunlora Drive intersection with
median acceleration lane). VDOT highly recommends using HCS 2010/2000 for Synchro
output reports and requests consistency across outputs.
3. Synchro files for the build condition do not appear to be coded correctly for the following
reasons:
• For the right in and full movement entrances, no right turn taper was included.
Please provide a minimum 100 ft. taper at both locations. This is required per
Appendix F of the VDOT Road Design Manual.
• At the right in entrance, the model shows two lanes (through and through/right)
for the upstream and two lanes downstream with a merge area. This configuration
does not match what is recommended in the "Recommendations" section.
4. The Synchro model for No Build 2023 PM Peak hour appears to have an incorrect right
turn volume for the intersection of Dunlora Drive.
5. Figures 11, 12 and 15; The Pen Park Road trip assignment appears to be incorrect. The
left and right turn volumes from Lochlyn Hill residential development were added to the
through movement. Please revise accordingly.

b. VDOT does not recommend extending the proposed SBL lane in to Dunlora Drive to the
Rio Road/John Warner Parkway intersection as it may create safety conflict concerns
between Dunlora Drive traffic and WBL traffic from Rio Road.
7. VDOT recommends submitting a conceptual layout of the improvements to Rio Road
along the subject property's frontage. There are numerous geometric elements that must
be reviewed and may impact the site's layout constraints.
8. At the full movement driveway, the NB left turn lane must have a minimum 100 ft.
storage and 100 ft. taper.
9. VDOT recommends evaluating an acceleration lane for EBL traffic at the full movement
entrance.
A VDOT Land Use Permit will be required prior to any work within the right-of-way. The
owner/developer must contact the Charlottesville Residency Transportation and Land Use
Section at (434) 422-9399 for information pertaining to this process.
