Traffic Operations: No Build 2050

Most intersections on US-95 in Moscow currently operate at an acceptable level of service (LOS). LOS is graded from A to F. Worsening LOS represents increased delays and wait times. We anticipate some specific intersections and single-lane movements will progress to an unacceptable LOS by 2050, our study design year.

Non-Signalized Intersections​

US-95 traffic flow would remain stable, but movements from side streets onto or across US-95 would experience significant delays at:​​​​

  • Rodeo Drive 

  • Morton Street ​

  • C Street

  • 1st Street​

  • Styner Avenue

  • Southview Avenue​

Traffic Queuing​

The most frequent vehicle movements on US-95 are near capacity and will continue to worsen without improvements:​

  • Northbound US-95 to westbound 3rd Street.

  • Eastbound from Jackson Street (US-95) onto SH-8. Queuing on Jackson Street will cause delays on College Street.

Level 2 Traffic Analysis Summary​

Additional information about these concepts will be detailed on the meeting displays.

Concepts/Options Carried Forward Through Traffic Analysis

​

  • New Corridors - 17 Concepts​​

    • Northeastern corridor concepts did not provide traffic benefits compared with other corridors

    • New corridor concepts to the south and west of Moscow met the Purpose & Need

​

  • Rural Widening and Rural Improvement Concepts​​

    • Both concepts passed through traffic analysis.

​

  • Signal Operation Improvements​​

​​

Concepts/Options Eliminated Due to Traffic Analysis

On their own, these concepts do not remove enough traffic from downtown Moscow to meet the Purpose & Need of the study.​

​

  • A Street

​

  • ​​Access Management​

​

  • Lane Reallocations​​​​​​​

​

  • Palouse River Drive​​

    • As a stand-alone concept, Palouse River Drive did not meet traffic performance need. Palouse River Drive will be a component of several New Corridor Concepts in Level 3 and will potentially be addressed as an off-system improvement for other studies.​​

​

  • Styner Avenue​​

    • Eliminating the Styner concept using the traffic data does not preclude it from being analyzed as part of the crosswalk concepts that were carried forward.
