The US 90A 4th quarter travel times show that the City met the service level commitments for
all peaks. All peaks showed little to no change in travel times when compared to the 3rd quarter.
      - 15 seconds travel time increase for AM Peak; remain LOS B
      -  -3 seconds travel time decrease for Noon Peak; remain LOS B
      - 9 seconds travel time increase for the PM Peak; remain LOS B


The 3rd quarter showed the lowest average daily volumes seen during the COVID-19 pandemic.
Since the start of the 4th quarter in July, the volumes on US 90 have been steadily increasing.
Using SH6, Eldridge, and Dairy Ashford as the reference points, the 7-day rolling average have
increased from 54,600 vehicles per day (vpd) on July 1st to approx. 63, 500 vpd on September
30th. When comparing the end of the 4th quarter to same time last year the volumes are
approx. 8,700 vpd less. Train activity has increased slightly since last quarter with data showing
approx. 32 trains per weekday.


Average travel times for Highway 90 between Dairy Ashford and Highway 6 are below:
      - AM: 4 minutes 30 seconds (39.2 mph, LOS B)
      - Noon: 4 minutes 38 seconds (38.1 mph, LOS B)
      - PM: 4 minutes 42 seconds (37.5 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). This measurement is attained for the AM peak (7-8 AM), Noon Peak (12-1 PM), and the PM peak (5-6 PM), when the major travel corridors in the City of Sugar Land typically experience high travel demands. 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 US Highway 90, this means the City aims to have a traffic goal of at least 25 - 34 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.
