Review #1
Dear Mr Reitelbach:

The Department of Transportation, Charlottesville Residency Transportation and Land Use Section, has
reviewed the above referenced plan as submitted by Bottler, dated 18 May 2019, and find it to be
generally acceptable.
1. Traffic Impact Analysis (TIA) comments :
VDOT Traffic Engineering offers the following Comments:
• Page 1: the counts and collection dates do not match and will be corrected.
• Page 6:
TE recommends 100-ft storage and 100-ft taper for Ashwood @ Archer Ave. The
construction of the left turn lane may lead to the closure of the existing median break.
TE recommends 200-ft storage and 200-ft taper to comply with the VDOT access
management for turning lane length of taper and storage for US 29@ R1RO
Driveway.
Please include the following recommendations in revised analysis.
Synchro Files:
AM and PM existing models do not have the correct existing total split timing, yellow
timings and all red timings. Considering this intersection is coordinated with other
intersections along US 29, the existing timings need to be used throughout all scenarios. If
signal -timing modification is deemed necessary to accommodate the development, the
modified signal timings should be added to the recommendation section for review.
Furthermore, any signal timing modification to this intersection may require updating the
entire coordination system along US 29. Obtain the correct existing timings from
VDOT/1'OC and update Synchro files accordingly.
Lost time adjustment is coded incorrectly throughout all scenarios (Existing, No -Build and
Build). Use the default value of "0". Side note: VDOT/ TE commented in this practice from
RKA several times at different occasions. Refer to Synchro guide for information in regards
to the lost time adjustment.

The existing condition has a pedestrian phase, which was not coded into Synchro. Add the
pedestrian phase for all scenarios.
Level of Service Summary tables uses Synchro output values; however, per TOSAM "HCM
2010 should be used for reporting Synchro analyses. If HCM 2010 reports are not generated
because of the operation of the intersection, HCM 2000 should be used". Revise all the
summary tables to include the HCM values and all attached reports are to be HCM 2010/2000
reports.
• Southbound left turn lane is coded incorrectly throughout all scenarios (Existing, No -
Build and Build). SBL is coded as a protected permissive; however, SBL is in a protected
only mode. Revise Synchro models to match the existing condition of the SBL operation.
VDOT TE performed internal analysis for the PM Build model using existing timing. The
analysis showed that the 95' queue length of the SBL will spillover to the US 29 and the
Synchro queue length is #313-ft. As a result, TE recommends that the SBL storage needs
to be extended an additional 150-ft to accommodate the long queues during the PM peak.
2. Note that the final plan must show conformance with the VDOT Road Design Manual
Appendices B(1) and F, as well as any other applicable standards, regulations or other
requirements.
If further information is desired, please contact Max Greene at 434-422-9894.
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.
