Reviewing for Improvement
There was a change in levels of service (LOS) for the AM peak (B to C), no change for the noon peak, and an increase in LOS for the PM peak (D to C).
The AM Peak decrease is primarily due to the opening of the eastbound lanes from SH 99 to Easton in September, which increased traffic approximately 35%.Traffic is currently looking into way
s to work through train interruptions and accommodate the extra traffic in morning. Additional change in lanes improved the PM peak.
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 Under Development
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.
