that for the multifamily land use considered, 15% of the daily traffic occurs in the morning (7am ‐ 8am) and
9% occurs just before noon (11am – 12pm). Therefore, the morning peak hour was used for analysis. The
peak just before noon was not used.
Based on the 2018 City of Southlake Traffic Count Report, existing turning movement volumes were grown
by 10% annually to estimate the background volumes for the buildout year (2021). These buildout
background volumes are shown in Figure 5.

Trip Generation
The number of trips generated by a development is a function of the type and quantity of the land use within
the development. The number of vehicle trips generated by a proposed development can be estimated based
on the trip generation rates and equations provided in the publication entitled Trip Generation Manual, Tenth
Edition, by the Institute of Transportation Engineers (ITE). Estimates of the number of trips generated by the
development alternatives were made for typical weekdays and AM and PM peak hours.
The trip generation equations, directional splits, and the estimated trips are shown in Table 1.

Trip Distribution and Assignment
The existing traffic volumes were reviewed along with the location of the proposed development to
determine the directions from which traffic would approach and depart the development. The directional
distribution used for analysis assumes that 30% of the trips that access the site come from the south, and
70% from the north. Traffic volumes predicted to be generated by the proposed development (Table 1) were
assigned to the area roadways and site access points based on the directional distribution described above.
Assignment percentages for entering and exiting peak hour trips are shown in Figure 6 and Figure 7
respectively. This traffic assignment is conservative because all site traffic has been assigned to the proposed
driveways on the parking facilities developed with the proposed development. None of the site traffic has
been assumed to park on the street. The resulting site generated peak hour trips are shown in Figure 8
(entering) and Figure 9 (exiting). Total site generated peak hour traffic volumes are shown in Figure 10.
Total Traffic Volumes
The projected total traffic volumes in the buildout year (2021) were calculated by adding the site generated
traffic volumes to the background traffic volumes. The projected total traffic volumes at the study
intersections under buildout conditions are shown in Figure 11.

Intersection Capacity Analysis
The Level of Service (LOS) of an intersection is a qualitative measure of capacity and operating conditions and
is directly related to vehicle delay. LOS is given a letter designation from A to F, with LOS A representing very
short delays and LOS F representing very long delays or over‐capacity conditions. Table 2 shows the LOS
criteria for signalized and unsignalized intersections and approaches.

1 HCM methodology does not provide intersection‐wide delay/LOS for TWSC analysis
2 Additional westbound right turns reduced the average delay – thereby improving LOS from E to C.
* LOS for Left Turn Movement
** LOS for Right Turn Movement
As shown in Table 4, all intersections and most approaches operate at level of service C or better in all
scenarios. In the 2021 Buildout Total scenario, the addition of westbound right‐turning traffic volumes
decreases the average vehicle delay, and thereby improves the level of service from E to C. The westbound
approach of Carroll Avenue at Division Street has enough width to be restriped in order to add a right turn
only lane. The addition of this right turn lane would slightly reduce the approach delay. However, the stop‐
controlled approaches (EB & WB) of Division Street at Carroll Avenue operate at poor levels of service due to
the delay associated with crossing against conflicting Carroll Avenue traffic. This is not due to lack of capacity,
but to lack of available gaps for left‐turning and through‐moving vehicles.
Page 16 of 19
As shown earlier in Figure 9, it was assumed that due to the existing poor level of service, drivers exiting the
north driveway to go south on Carroll Avenue would prefer to avoid making a left turn at the stop‐controlled
westbound approach of Division Street and would instead turn left at the signalized westbound approach of
Federal Way. If Carroll Avenue at Division Street were signalized in the future, levels of service would likely
be similar to those at Carroll Avenue at Federal Way. In that case, drivers exiting the north driveway to go
south on Carroll Avenue would likely turn left from Division Street. In this way, signalization of Carroll Avenue
at Division Street would draw traffic away from the westbound approach of Carroll Avenue at Federal Way.
It is possible that other preferred area routes would be similarly affected.
Right Turn Lane Analysis
According to Southlake Driveway Ordinance No. 634:
“5.4 AUXILIARY LANES – a. WHEN REQUIRED: As a condition of a Driveway Permit, the
Applicant shall provide a deceleration lane for any driveway located on an arterial street if
the right turn ingress volume exceeds 50 vehicles in the design hour…”
Carroll Avenue is the only arterial street with a proposed driveway. Table 5 summarizes the predicted right
turn volumes under (2021) buildout total traffic conditions (Figure 11) at the proposed West Driveway on
Carroll Avenue.

As shown in Table 5, a right turn deceleration lane is not needed at the proposed West Driveway on Carroll
Avenue.
Access Spacing
According to Southlake Driveway Ordinance No. 634, a driveway on an arterial road needs to meet the
following criteria described in Table 6:
Table 6: Access Spacing Analysis Results
Distance to Required
[Feet]
Proposed
[Feet]
Meets Required
Distance?
Intersection 200 ~250' Yes
Centerline of Other Driveway(s) 250 ~420' Yes
As shown in Table 6, the proposed West driveway location will meet to the required access spacing distances.
Page 17 of 19
Sight Distance Evaluation
As part of this traffic analysis, the available and desired intersection sight distances for motorists accessing
adjacent streets from the proposed site were analyzed. The sight distances desired at each site exit driveway
were estimated using the procedures developed by the American Association of State Highway and
Transportation Officials (AASHTO) and published in the 2011 edition of A Policy on Geometric Design of
Highways and Streets. At each driveway, the motorist should be able to see if and when adequate gaps exist
to perform their desired maneuver. Table 7 presents the desired and available sight distance at the proposed
site access point.

Available Sight Distance to the Right: N/A

Sight Distance Available > Desired: N/A1 No Yes No
1 Right in/Right out driveway
At the time of the field visit to the site and under the existing roadway conditions, desired sight distance is
predicted to be available for the exiting traffic from the proposed development at driveways on Carroll
Avenue and State Street. Though desired sight distance is not predicted to be available on Division Street or
Federal Way, stopping sight distance is predicted to be available for traffic on all approaches that pass a
proposed driveway.
Intersection sight distance methodology assumes that through traffic is travelling at the speed limit.
However, vehicles on Division Street and Federal Way near the proposed driveways will be turning from cross
streets or accelerating from a stop – travelling below the speed limit of 30 mph. Available intersection sight
distances at the proposed locations of the north and south driveways are adequate for these conditions.
Proposed driveway configurations will be similar to other midblock access points throughout Southlake Town
Square:
the driveway for the East Park garage on Federal Way (southwest of the movie theater),
the north/south street on Prospect Street between Charming Charlie and Tempur‐Pedic,
the driveways on the north side of Main Street between Carroll Avenue and State Street, and
the driveways on Main Street between Grand Avenue and Central Avenue.
Note that, as with the existing driveways listed above, while on‐street parking could partially obstruct lines
of sight at any driveway, the sight triangles are free from fixed obstructions such as buildings and landscaping.
Lee Engineering recommends maintaining intersection sight triangles free from fixed obstructions at the
proposed driveways.
