The State Highway 6 (SH 6) 3rd quarter travel times show that the City met the service level
commitments for all peaks. All peaks showed significant travel time decreases when compared
to the 2nd quarter.

  •  -41 seconds decrease for AM Peak; LOS B to A
  •  -31 seconds decrease for Noon Peak; LOS C to B
  •  -128 seconds for the PM Peak; LOS C to B
The start of the 3rd quarter (April 1) marked the lowest average daily volume seen for the SH 6
corridor during the COVID-19 pandemic. SH6/59 was only seeing approx. 56,000 vehicles a day
(vpd) which is a little less than half the volume when compared to FY19 (119,000 vpd) at the
same time. By the end of the 3rd quarter volumes increase to approx. 99,000 vpd by mid June
but fell back down to approx. 91,000 before the end of month. The drastic difference in
volumes led to significant decreases in measured travel times.
Average travel times details on Highway 6 from Dulles Ave to First Colony Blvd/Brooks St are
outlined below:
  •  AM: 5 minutes 28 seconds (38.7 mph, LOS A)
  •  Noon: 6 minutes 44 seconds (31.5 mph, LOS B)
  •  PM: 6 minutes 36 seconds (32.1 mph, LOS B)

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.
