Q2-19

The results for the second quarter of FY19 show that the City met the Level of Service for AM and Noon peak times but did not to meet the Level of Service in PM peak time. The PM peak time did however see a 51 second travel time reduction from First Colony Boulevard/Brooks Street to Dulles Avenue when compared to the first quarter. 

During the second quarter, SH 6/US 59 interchange averaged just over 120,000 vehicles per day followed by SH 6/Brooks and SH 6/Dulles intersections which saw approximately 79,300 to 79,700 vehicles per day. The SH 6 section north of 59 still continues to be the slowest section, specifically southbound from Brooks Street to US 59 in the PM peak time. This section carries approximately 64,000 to 67,000 vehicles per day northbound and southbound on SH 6. The scheduled expansion of SH 6 from 3 lanes to 4 lanes will help with the corridor performance with construction currently under way.

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

  • AM: 6 minutes 13 seconds (34 mph, Level of Service B)
  • Noon: 7 minutes 41 seconds (27.6 mph, Level of Service C)
  • PM: 9 minutes 40 seconds (21.9 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 traffic goal 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 traffic goal 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.
