Proceeding as Anticipated
Reviewing for Improvement
The State Highway 6 (SH 6) 1st quarter travel times show that the City met the service level commitments for all peaks (AM, Noon, PM) with a level of service of C or better. All peaks did however showed travel time increases when compared to the previous quarter. This is expected due to increases in holiday traffic leading up to Christmas day and lane closures due to SH 6 reconstruction from US 59 to Brooks.
When compared to the previous year, the PM peak travel time is 64 seconds shorter (faster) than last year’s FY20 1st quarter PM peak. This is most likely due to decrease in traffic volumes due to Covid-19. Traffic volumes along SH 6 corridor have remained consistently 9,000 - 12,000 trips lower when compared to pre-COVID-19 data (FY19). For this quarter, the SH 6 at US 59 interchange averaged 107,500 vpd for weekdays. The least busy day was on Christmas Day with only 44,600 vehicles and the busiest day was on December 23 with 125,000 vehicles.
Average travel times details on Highway 6 from Dulles Ave to First Colony Blvd/Brooks St are outlined below:
- AM: 5 minutes 58 seconds (35.5 mph, LOS B)
- Noon: 7 minutes 35 seconds (27.9 mph, LOS C)
- PM: 8 minutes 47 seconds (24.1 mph, LOS C)
Per the 2010 Highway Capacity Manual, this metric is calculated as the average measured travel speed over the posted speed limit for the corresponding major corridor (avg. speed / posted speed limit). The calculated value is converted into a percentage and translated into a letter grade indicative of a Level of Service (A is the best, F is the worst). The slower the measured speed compared to the posted speed limit, the lower the Level of Service.
Measured major travel corridors include:
State Highway 6 (Dulles to Brooks St.) - 45 MPH
US Highway 90 (Dairy Ashford Blvd. to SH 6) - 50 MPH
Standard Levels of Service are classified by the 2010 Highway Capacity Manual.
A: ≥86% B: 68%-85% C: 51%-67% D: 41%-50%
E: 31%-40% F: ≤30%
A target of C means the City aims to have traffic flowing at a minimum of 51-67% of the speed limit. For Highway 6, this means the City aims to have a traffic goal of at least 23 - 30 MPH during the AM, noon, and PM peak travel times.
The City of Sugar Land's most vital vehicular travel corridors support commercial enterprise and quality of life. Shorter travel times help improve both commercial enterprise and quality of life.
