Recognized for more than 35 years of experience in traffic engineering, transportation planning, and multimodal safety analysis, this traffic engineering and transportation safety expert witness specializes in transportation planning, traffic engineering evaluation, crash analysis, roadway and intersection safety assessment, traffic operations, and project formulation for multimodal transportation system improvements. The expert has more than 20 years of experience providing consultations, depositions, and courtroom testimony involving traffic engineering, roadway safety, transportation operations, railway crossing evaluations, pedestrian safety, and traffic-related incident analysis. Areas of expertise include crash-history evaluation, traffic safety countermeasure development, transportation systems analysis, roadway operational assessment, traffic flow analysis, traffic records systems, transportation forecasting, and development of safety-focused transportation improvement strategies for public infrastructure and roadway networks.

Professional leadership responsibilities have included engineering analysis, transportation planning, project coordination, and technical evaluation involving roadway systems, traffic operations, and multimodal transportation infrastructure for both consulting engineering organizations and municipal governments. The expert spent 16 years serving as a transportation planner and traffic engineer for major municipalities, where responsibilities included preparation of six-year transportation improvement programs, development of transportation project prioritization criteria, analysis of roadway deficiencies, crash-rate evaluations, safety improvement planning, and participation in statewide and regional transportation planning initiatives. Additional expertise includes Highway Safety Improvement Program (23 CFR 924) evaluations, Statewide Transportation Improvement Program coordination, transportation policy development, traffic records protocol development, traffic-count collection, crash-data analysis, and preparation of transportation forecasting models used to evaluate roadway safety and capacity needs. Professional credentials include licensure as a Professional Engineer (P.E.) in multiple states and certification as a Professional Traffic Operations Engineer (P.T.O.E.). Educational attainment includes a Master of Science degree in Civil Engineering with specialization in Transportation Planning and a Bachelor of Science degree in Civil Engineering with specialization in Traffic Engineering.

Professional transportation safety and consulting experience includes extensive involvement in roadway safety investigations, transportation system evaluations, multimodal planning studies, and public infrastructure improvement initiatives. The expert has conducted crash and safety analyses for roadway segments, arterial systems, and major intersections, including identification of safety deficiencies, development of prioritized countermeasure programs, and evaluation of roadway and traffic-control conditions affecting vehicular and pedestrian safety. Additional project experience includes safety evaluations of at-grade railway crossings, pedestrian circulation studies following traffic fatalities, multimodal transportation planning, transportation improvement prioritization, and operational assessments involving public roadway systems and transportation infrastructure.

The expert has also served as a technical advisor for regional transportation committees responsible for development of transportation funding priorities and statewide transportation planning coordination. Professional leadership and industry involvement include Fellow status with the Institute of Transportation Engineers, service as Past President of the Washington State Section of ITE, membership on the ITE Transportation Safety Council, chairmanship of the Washington State Section ITE Safety Committee, and participation with the Washington State Traffic Safety Commission in development and support of statewide safety initiatives. Additional professional activities include publication authorship involving transportation planning and work-zone traffic control, as well as ongoing consulting related to roadway safety evaluation, traffic operations analysis, transportation improvement planning, and multimodal transportation systems.
