Q3-18

The results of the 3rd quarter showed that the City met or exceeded the Level of Service (LOS) C targets as summarized below. The PM continues to be the biggest challenge as it carries significantly more traffic than the AM peak hence the approximate 2-minute difference in travel times. The slowest segment seems to be the southbound segment from Brooks Street to US 59. The Public Works Department will continue to evaluate how to best improve this segment of travel time. Currently there is a project to expand SH 6 from three lanes to four lanes which should decrease travel times upon completion. All data reported for the SH 6 travel times were gathered by Bluetooth read-matching technology which provides insight to problem areas and periods.

Average travel times(metrics) for the 3rd quarter are summarized below:
  • AM: 6 minutes 16 seconds (33.9 mph, LOS B)
  • Noon: 7 minutes 58 seconds (26.6 mph, LOS C)
  • PM: 9 minutes 7 seconds (23.3 mph, LOS C)

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 data collection method called the floating car method in which two staff members drive the traffic corridor in each direction. One staff member drives the car, while the other records the average measured travel speed over the posted speed limit. This exercise is conducted each quarter, for each of the peak travel times: AM, Noon, and PM.
