  • Valley Spur - Year 2019 Existing Unsignalized Configuration
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the existing unsignalized intersection configuration. Based on year 2019 forecast volumes, the intersections are expected to operate acceptably during and after train crossings.
  • Valley Spur - Year 2040 Existing Unsignalized Configuration – Part 1
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the existing unsignalized intersection configuration. Based on year 2040 forecast volumes, the eastbound left-turn and west-bound right-turn movements at the Valley Center Road/Valley Spur Road intersection are expected to spillback into the through lanes during/after train crossings.
  • Valley Spur - Year 2040 Existing Unsignalized Configuration – Part 2
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the existing unsignalized intersection configuration. It shows a second train crossing which occurs 10 minutes after the train crossing shown in Part 1. Based on year 2040 forecast volumes, the eastbound left-turn and west-bound right-turn queues from the first train crossing will not clear before the second train. The second train crossing will result in additional queue spillbacks and blockage of the through lanes on Valley Center Road.

  • Valley Spur - Year 2019 Permissive Phasing
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the proposed near term traffic signals. Based on year 2019 forecast volumes, the intersections are expected to operate acceptably.
  • Valley Spur - Year 2040 Permissive Phasing
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the proposed near term traffic signals. Based on year 2040 forecast volumes, the eastbound left-turn lane at the Valley Center Road/Valley Spur Road intersection is expected to spillback into the eastbound through lane during/after train crossings.
  • Valley Spur - Year 2040 Split Phasing
    This video shows the Frontage Road/Valley Spur Road and Valley Center Road/Valley Spur Road intersections with the proposed future traffic signal phasing. Based on year 2040 forecast volumes, the intersections are expected to operate acceptably during and after train crossings.
