Geographical Information Systems (GIS) –
Comfortable using GIS software (ArcView and TransCAD) in the development
of land use assumptions and preparation of graphical materials as
part of travel demand model development. 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. Project manager
for the development of the initial Guidelines for Major Transportation
Investment Studies (MIS) for the Portland Metropolitan Area.
Traffic Impact Fees – Project manager for
the 1999 City of Newman Traffic Impact Fee Update. Project engineer
contributing to the development of traffic impact fees for the City
of Fremont, the Tri-Valley area and the Lamorinda subarea in the
Bay Area, and jointly for the City of Gresham and East Multnomah
County in Oregon. Responsibilities included: evaluation of existing
and future conditions, development of mitigations measures, calculation
of fee, and nexus analysis.
Congestion Management Systems – Project
manager responsible for the development of the Interim Congestion
Management System (CMS) for the Portland Metropolitan Area, which
remained in effect until the final CMS was adopted. 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
