RE:SPEED STUDY FOR KENNEY FORT BLVD BETWEEN FOREST CREEK DR AND THE SH 45
FRONTAGE ROADS
The City of Round Rock Transportation Department has completed a speed study along Kenney Fort
Blvd between Forest Creek Dr and the SH45 Frontage Roads.The objective of this study was to
assess the current speed within the area and post speed limit signs that are appropriate based on
the collected data. Note that this study did not include evaluations of curve advisory speeds or
school zone speed limits. Below is a summary of the study's methodology,findings, and
recommendations.
EXISTING CONDITIONS
Kenney Fort Blvd is a six-lane arterial road (three lanes in each direction)with a raised center
median. Minimal driveways and side streets connect to this section of the roadway.These access
points adhere to the City's access management policies in terms of spacing and design.There is
currently no posted speed limit. The Texas Transportation Code defines 45 mph for an arterial that
has no posted speed limit. Figure 2 shows the study area and the location of proposed speed limit
signs. Table 2 shows the boundaries of the existing speed limits.
DATA COLLECTION
In accordance with TXDOT's Procedures for Establishing Speed Zones manual, specific criteria
were followed to collect accurate speed data.The manual advises that speed checks should:
• Be conducted on average weekdays during off-peak hours
• Occur under favorable weather conditions
• Include only free-flowing vehicles(not impeded by traffic signals or congestion)
• Record a minimum of 125 vehicles in each direction at each location
• Be completed within a two-hour window when radar equipment is used

(F) 512.218.5555•(F) 512.255.6916•roundrocktexas.gov
NDS Data Services conducted speed measurements using radar technology at four locations along
the study area,capturing both northbound and southbound traffic during March 2025.These
Locations are shown in Figure 1,with detailed data included in the Field Tally Sheets(Appendix A).
Below is a summary of the measured 85th percentile speeds at each location.

Approx.3,600 feet north of Gattis School Rd RAD-004 60 54
Table 1:Collected Data
SPEED STUDY METHODOLOGY
TXDOT's manual recommends using the 85th percentile speed of free-flowing traffic as the basis for
determining appropriate speed limits.The 85th percentile speed represents the speed at or below
which 85%of drivers are traveling under ideal conditions.This method is widely accepted and
based on the assumption that most drivers:
• Are prudent and drive safely
• Aim to avoid crashes
• Want to reach their destinations as quickly as possible
A speed limit set at or near the 85th percentile speed is considered safe under good weather and
visibility conditions.The final posted speed limit is typically rounded to the nearest 5 mph.
However, it can be adjusted up or down by up to 5 mph, depending on the professional judgment of
the supervising engineer.

(P) 512.218.5555.(F) 512.255.6916•roundrocktexas.gov
RESULTS AND RECOMMENDATIONS
The study's findings indicate 85th percentile speeds ranging from 53 mph to 60 mph,which are
generally consistent. Based on this data,the recommended speed limit for the entire study area is
55 mph.
Considering the data collected,the Transportation Department recommends adjustingthe speed
limits as follows:
From To Existing Speed Limit Proposed Speed
(NB/SB) Limit(NB/SB)
Forest Creek Dr SH 45 Frontage Roads 45 mph (based on Texas 55 mph
Transportation Code)
Table 2:Recommendations
Recommended sign locations are shown in Figure 2.
