**Due to fiber break on SH 6, the data presented for this quarter is missing travel time data
from March 9th, 2021 to March 31st, 2021. The adaptive system has also been offline during this
time.

The State Highway 6 (SH 6) Q2 travel times show that the City met the service level
commitments for all peaks (AM, Noon, PM) with a level of service of C or better. All peaks
showed little to no change when compared to the previous quarter. This quarter had significant
road closures from I-69 to Brooks as contractors are trying to finish SH 6 expansion project.
When compared to the same quarter last year, noting COVID-19 started in March, all peak
travel times have stayed approximately the same. Traffic volumes along SH 6 corridor have
remained consistently 12,000 trips lower when compared to pre-COVID data. For this quarter,
the SH 6 at US 59 interchange averaged 104,000 vpd for weekdays.
Average travel times details on Highway 6 from Dulles Ave to First Colony Blvd/Brooks St are
outlined below:

- AM: 5 minutes 56 seconds (35.7 mph, LOS B)
- Noon: 7 minutes 47 seconds (27.2 mph, LOS C)
- PM: 8 minutes 45 seconds (24.2 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 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.
