SUBJECT: The Lind Property Development, Filing 1 Transportation
Impact Study Addendum - Roundabout analysis at
arterial/arterial intersections (File: 0212MB01)
w
O
N
Cr
0)
0
CD
The Fort Collins Code requires that the transportation impact
w
o
study (TIS) contain a roundabout analysis at all arterial/arterial
a
r
intersection that are included in the TIS. There were six arterial/
arterial intersections that were included in the TIS: Vine/Lemay,
Z
W
o
Vine/Timberline, Timberline/Mountain Vista, Mountain Vista/CR9, CR11/
U
x
Country Club, and CR11/CR52. Staff indicated that the Vine/Lemay and
N
r
a
Vine/Timberline intersections did not require analysis due to the
N
complications caused by the proximity of the railroad tracks. The
N
other intersections were not analyzed as roundabouts in the TIS,
since they were shown to operate acceptably with conventional stop
sign control. This memorandum provides the roundabout analysis at
these intersections.
Appendix. A contains Figure 7, Short. Range (2006) Total Peak
Hour Traffic from the cited TIS. The marked intersections were
analyzed as single lane roundabouts using the 2000 Highway Capacity
Manual. This technique does not/.alculate level of service of or
delay to the entering traffic. Instead, it provides a
