The State Highway 6 (SH 6) 1st quarter travel times show that the City met the service level commitments for the AM & Noon peaks (LOS B & C) but failed to meet the service commitment for PM peak with a LOS of D. 

All peaks showed travel time increases when compared to the previous quarter. When compared to the fall of 2019 (last pre-covid quarter), the PM peak travel time is almost identical. The slow travel times are strongly correlated to the increases in holiday traffic leading up to Christmas day. Traffic measurements at SH 6/US59 show a steady increase from October 1st (approx. 112,000 vehicles per day) until it peaks the week before Christmas (approx. 125,000 vehicles per day). Volume trends also show that the PM commute was hit hardest most likely due to shoppers heading to Town Center area after work hours. 

Average travel times details on Highway 6 from Dulles Ave to First Colony Blvd/Brooks St are outlined below: 

  • AM: 5 minutes 59 seconds (35.4 mph, LOS B) 
  • Noon: 8 minutes 0 seconds (26.5 mph, LOS C) 
  • PM: 9 minutes 50 seconds (21.5 mph, LOS D) 

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%

Target: C/C/C

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.

City of Sugar Land Public Works Department - Traffic Division; The Traffic Division currently uses a Bluetooth data collection method tracking travel time data that is collected daily for the entire quarter. This method of reading travel times better serves to capture the actual average travel times on a daily basis.
