The State Highway 6 (SH 6) 1st quarter travel times show that the City met the service level commitments for the AM and Noon peaks but did not meet the service level commitment in the PM peak. The AM and Noon peak showed negligible travel time changes through holiday traffic season. The PM peak however suffered with a 66 second increase in travel time from Brooks St. to Dulles Ave. There is no supporting data but the increase may be due to the temporary lane narrowing as part of the SH 6 project. Previous year data shows FY20’s 1st quarter is 40 seconds faster than last year’s FY19’s 1st quarter.

SH 6/US 59 interchange had a slight weekday average increase from 121,200 to 122,200 vehicles per day (vpd). This quarter had the second busiest day of the 2019 calendar year at 136,300 vpd and the least busiest day on Christmas day with 53,800 vpd. Fridays continue to be the busiest day of the week with average vehicles per day increasing from 130,250 to 131,025 vpd. The rest of the SH 6 corridor showed similar volume increases.
Average travel times details on Highway 6 from Dulles Ave to First Colony Blvd./Brooks St. are outlined below:

  • AM: 6 minutes 7 seconds (34.6 mph, LOS B)
  • Noon: 7 minutes 41 seconds (27.6 mph, LOS C)
  • PM: 9 minutes 51 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.
