Washington Transportation News - March 2006 


Doug Brodin appointed Acting Director, Office of Research and Library Services

From April 3, 2006 through June 2, 2006, Doug Brodin is delegated my authorities and appointed as the Acting Director, Office of Research and Library Services. Doug can be reached at and 360-705-7972. April 3rd, Leni Oman will be on a rotational assignment to FHWA's Turner Fairbank Highway Research Center McLean, Virginia just outside of DC. She will assist FHWA develop and implement the Advance Research Program established in SAFETEA-LU and working with the Research and Innovative Technology Administration to incorporate advanced research into their programs. She'll also assist in the development of the new USDOT Surface Transportation Environmental and Planning (STEP) cooperative research program and help develop tools to assist continued communication with state DOTs on transportation research.   

Fish Passage Research Presented to Five States

Fish passage research conducted during the last year at the Skookumchuck Fish Hatchery was presented in March at a meeting near SeaTac with DOT officials from Alaska; Oregon, California and Montana. Representatives from Federal Highways Administration, Washington Department of Fish and Wildlife, and several people from private timber interests were also in attendance. Researchers from the University of Washington and Washington State University presented results of hydraulics testing using the test bed. The Battelle scientists presented results on fish behavior trials that were conducted. Findings included:

  • Confirmation that the current standards for baffles for adult salmon appear to also allow successful passage for juvenile salmonids.
  • Understanding how the velocity of the water in a corrugated pipe effects the salmon migration.
  • Recognition that the successful passage of fish relies on a “system” of conditions prior to and exiting a culvert.

The meeting concluded with a discussion of future research strategies and possible funding partnerships that could be pursued. To download the presentation, visit then click on "incoming" and look for a folder that is titled "Fish Passage Research". If you have questions, please contact Rhonda Brooks, 360.705.7945.

Three New Research Projects Started In March 2006

  • A new task order was issued to Texas Transportation Institute for the project “Anchored Temporary Concrete Barrier Systems”. The amount allocated to the project is $55,098 and the Principal Investigator is Nauman Sheikh.
  • The University of Washington will be conducting a project called “Multimodal Concurrency Study” valued at $125,000. Mark Hallenbeck is the Principal Investigator. The work is funded by the Legislature through the Puget Sound Regional Council and the WSDOT Planning Office.
  • A project entitled “Identification and Evaluation of Traffic Data Gaps” has been awarded to WSU in the amount of $50,000. The project Principal Investigator is Eric Jessup. Project funding is being provided by the WSDOT Traffic Data Office.

Ferry Impacts on Salmonids under Review

A draft report has been issued by the Battelle Memorial Institute, “Impacts of Ferry Terminals, and Ferry Operations on Juvenile Salmon Migrating along Puget Sound Shorelines” is under review by Washington State Ferries and the Environmental Services Office. This report was commissioned two years ago to understand the nearshore impacts to migrating juvenile salmon. Upon finalization of the report, a technical seminar will be held later this spring for WSDOT biologists, WSF personnel and other interested federal and state agencies.
