RE: SPEED STUDY FOR E MAIN ST BETWEEN COLLEGE AND MOYE /ONALEaG\'�
The City of Round Rock Transportation Department has completed a speed study along E Main Street
between College Street and Moye Street. The purpose of the study was to document and evaluate the
existing posted speed limits within the study area. Curve advisory speeds and school zone speed
evaluation was not in the scope of the study. The following summarizes the study methodology, results,
and recommendations.
EXISTING CONDITIONS
E Main St is classified as a collector and consists of one lane in each direction with no median. The
segment is short and dead ends to the East.The segment is narrow with inconsistent shoulders,street
parking and residential driveways. The posted speed limit within the study area is 30 mph. The study
area and existing speed limit signs are shown in Figure 1.
DATA COLLECTION
TXDOT's"Procedures for Establishing Speed Zones" (Manual) provides guidance on collecting data for
speed studies. The Manual recommends that speed checks should:
• Be made on average weekdays at off-peak hours
• Be made under favorable weather conditions
• Include only free flowing vehicles
• Include a minimum of 125 cars in each direction at each location
• Be discontinued after two hours if radar is used,even if 125 cars have not been recorded
Speed spot data were collected by Quality Counts using radar technology at three locations within the
study area. The data were taken in both the east bound and west bound directions. The locations are
shown on Figure 1 and the Field Tally Sheets are in Appendix A.

Table 1: 85th percentile speeds recorded
SPEED STUDY METHODOLOGY
TXDOT's Manual provides guidance on the methodology for setting speed zones. The Manual suggests
using the 85th percentile speed of free flowing traffic as a basis for determining the appropriate speed
limit. The 85th percentile speed is used by many cities, counties, and states and is based on the theory
that a large majority of drivers:
• Are reasonable and prudent
• Do not want to have a crash
• Desire to reach their destination in the shortest possible time
Therefore,a speed at or below the recorded 85th percentile speed may be considered the maximum safe
speed under favorable weather and visibility conditions. The posted speed selected is the nearest value
ending in 5 or 0.The final speed limit may be lowered or raised by as much as 5 miles per hour from the
85th percentile determined by the study, based on the professional judgment of the supervising
engineer.
RESULTS AND RECOMMENDATIONS
Based on the results of the study,the 85th percentile speeds within the study area are between 29 mph
and 37 mph,which when rounded down to 35 mph is within 5 mph of the posted speed of 30 mph.
Considering the existing conditions listed above and the Prima Facia speed limit of 30 mph,the
recommendation of the Transportation Department is for the speed limit to remain at 30 mph.
Furthermore,the current speed limit sign placement is appropriate, and it is recommended that the
signs remain at their current locations.
