For the Tulare County regional model update, used ArcView’s geoprocessing tools with Tulare County assessor’s parcel database and shapefiles of model traffic analysis zones, city boundaries and census tract boundaries to develop existing and future socio-economic assumptions for the travel forecasting model. Prepared ArcView views, layouts and reports to display and summarize assumptions by local jurisdiction. Used ArcView to develop walk access assumptions by traffic analysis zone for the 2000 Kern Council of Governments regional model update.

Areawide and Citywide Monitoring Studies – Deputy project manager for the MTC Pilot Project for the Collection of Travel Time Data that identified and tested promising methods for collecting travel times, travel time variability, and user perceptions of travel time. Project manager for the Santa Clara Valley Transportation Authority 1997 CMP Monitoring and Conformance Study. Responsibilities included the collection, compilation and utilization of aerial photography, travel time runs, traffic counts, and origin-destination surveys to evaluate the performance of Santa Clara County’s freeways, expressways, rural roads and intersections. For three consecutive years (1988-1990) evaluated existing and future traffic conditions and travel patterns as part of the city of San Ramon’s Annual Traffic Monitoring Program.

Project Programming / Major Investment Studies – Project manager for the multi-disciplinary review and update of Washington State DOT's software (Excel workbook) for evaluating and prioritizing their mobility improvement projects. Software modifications included new and/or improved modules for estimating user benefits and evaluating HOV lanes and park-and-ride lots.

As project planner for the original development of Congestion Management Programs for Alameda and Marin counties, helped define CMP-designated transportation networks and evaluate adequacy of existing trip reduction ordinances and transportation system management programs in meeting CMP and Air Quality rule requirements.
Corridor Studies - Project manager for the development of the initial Guidelines for Major Transportation Investment Studies (MIS) for the Portland Metropolitan Area. As MPO liaison, participated on the technical advisory committees (TAC) of several major investment studies, including Hayden Island sponsored by the Port of Portland and Mt. Hood Parkway sponsored by the Oregon Department of Transportation. Project manager responsible for forecasting ridership for the commuter components of the proposed California High Speed Rail Project between Los Angeles and the San Francisco Bay Area. As project manager for initial phases of the South Willamette River Crossing Study in Portland, Oregon, developed work program and schedule, formed and chaired TAC, worked with local jurisdictions to identify study issues, goals and objectives, gave public presentations, and developed a range of reasonable alternatives. Project engineer for Route 85 Transportation Corridor Studies in Santa Clara County.

Environmental Review / Traffic Impact Analysis – Project manager for several traffic impact studies including the Redwood Covenant Church in Santa Rosa and the transportation and traffic evaluation for the Tigard Triangle Specific Area Plan in Oregon.
