Q3-19

The results for the third quarter of FY19 show that the City met the level of service for AM and Noon peak times but did not meet the level of service in PM peak time. The PM peak time did see a 20 second travel time increase  when compared to the second quarter.

During the third quarter, SH 6/US 59 interchange average volumes increased from just over 120,000 vehicles per day (vpd), to 124,100 vpd.  Additionally, third quarter Fridays show an average of 133,000 vpd with two Fridays in May hitting volumes over 138,000 vpd. The rest of the SH 6 corridor showed similar increases. The scheduled expansion of SH 6 from 3 lanes to 4 lanes will help with the corridor performance when completed but may cause some delays on the roadway throughout its completion.

Average travel times details on Highway 6 from Dulles Avenue to First Colony Boulevard/Brooks Street are outlined below:

  • AM: 6 minutes 6 seconds (34.8 mph, Level of Service B)
  • Noon: 8 minutes 5 seconds (26.2 mph, Level of Service C)
  • PM: 9 minutes 59 seconds (21.2 mph, Level of Service D)

Each peak time has a target of C, which 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. 

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.
