Alberta, CA (2014 - Present)

Developing Alberta's Spatial Economic and Transport (ASET) Model for economic and transportation infrastructure forecasting purposes for the Government of Alberta Ministry of Transportation. The two key component models of the ASET Model System are the Spatial Economic Model (SEM); and Travel Demand Forecasting Model (TDM). Additional functionality representing province-wide changes in economic activity, associated trade with the rest of the world, and population demographics is to be developed and integrated into this representation.

Edmonton, CA (2015 - Present)

Developing a new, functioning and calibrated Regional Travel Model (RTM) covering the Edmonton Region and training in-house staff at the City of Edmonton to appropriately use, interpret and modify this new RTM.

Calgary, CA (2015 - Present)

Atlanta, Georgia, USA (2007 - Present)

Technical leader on development of PECAS model for the Atlanta Region. Worked with staff at the Atlanta Regional Commission to bring together parcel data from 20 disparate counties and reconcile with employment, zoning, and census population data. Developed transportation cost coefficients for categories of goods, services, labour and personal trips. Presented PECAS theory and practice to stakeholders and decision makers.

Wuhan, China (2015 - Present)

We are working with Wuhan University of Technology for building PECAS models of the Wuhan and Shanghai.

Oregon Transportation Land Use Model Improvement Program: 2000-Present

Technical leader on program to design, develop, calibrate and apply new spatial economic models of the state of Oregon, including MEPLAN and PECAS land use models. Application of these models in policy analysis including new interstate roadway programs, bridge repair programs, urban growth boundaries and regional-level transportation plans.

Sacramento PECAS Model: 2007-2009, 2012+

Technical leader on development of PECAS model for the Sacramento Region. Processed IMPLAN input-output economic matrix to determine core relationships in PECAS, processed PUMS and Census data to develop representation of labor markets and housing markets, established transport cost functions for various goods, service, labour and personal movements, developed a synthetic representation of base-year built form to overcome categorical and other inconsistencies.

San Diego PECAS Model: 2007-2013

Technical leader on development of PECAS model for the San Diego Region. Developed incremental version of the PECAS model, established rent model based on observed data and detailed locational attributes. Provided advice and assistance for the processing of data on employment, land use regulations (zoning), land cover, census, travel model outputs, development permits, tax assessors records, real estate transaction history, school and other special generators, transportation cost data, import and export quantities and directionality by commodity, and others. Setup and installed software system and database design.

California PECAS Model: 2007-2010 Technical leader on development of PECAS model for the state of California. Worked with the University of California at Davis to train staff, students and post doctoral fellows in the development of PECAS. Developed grid-cell based representation of the state. Processed census data, elevator permit data, InfoUSA employment data, building permit data, commercial data on sales transactions and valuation assessment. Set up calibration scripts to establish dispersion parameters and constants for the various random utility models in PECAS. Developed and ran population synthesizer to synthetically generate a complete population for California and complete employment inventory for California. Liaised with client agencies and other funders.

Baltimore PECAS Model: 2007-2012
Technical leader on development of PECAS model for the Baltimore Region. Starting from a partially built TRANUS model, developed input-output matrix of the Baltimore economy and integrated the PECAS framework with the Baltimore Metropolitan Council (BMC) travel model. Calibrated the behaviour of persons and firms in terms of the labor markets, the real estate markets, and the flows of goods and services between firms and to households. Calibrated the behaviour of developers. Compared policy scenarios and prepared BMC staff for running the model for policy analysis.
