Annual Salary Range: $104,049 to $161,276

Close Date: 09/16/2022 - Opened Until Filled

The Transportation Analysis and Modeling group has two types of roles available that support model development and model application.

The Model Development team members maintain and improve a suite of models including Activity Based Model (ABM), Rapid Strategic Model (RSM), Commercial Vehicle Model (CVM), Crossborder Model (CBM), and other special market models. Key focus areas include the addition of new features related to emerging technologies, transformative transportation modes, and shared mobility. The Model Development team also support model applications in key agency projects, including regional, local, and border-related projects.

The Model Application team members apply the ABM in support of regional, local, and border-related projects. They prepare transportation networks, perform model runs, interpret and analyze results, and communicate model outputs through a wide range of data and mapping presentation formats.

Overview of the Data Science Department
As a premier multi-modal planning and project implementation agency, SANDAG relies on the quality and capacity of our Transportation, Demographic, Economic, and Land Use Modeling programs. A team of highly skilled professionals support a variety of projects including long-range coordinated transportation, economic, and land use plans, corridor studies, major transit investment studies, infrastructure and air quality plans.

As regional planning needs, travel behavior, and socioeconomic conditions change, the demands and expectations of our modeling program have increased. To meet these challenges, SANDAG has committed the resources necessary to develop and maintain a robust, agile, and integrated modeling infrastructure to support policy development and decision making. SANDAG has developed a nationally recognized and highly sophisticated ABM. As the future transportation system transforms, SANDAG will be updating its ABM, RSM, CVM, and CBM to respond to the impact of emerging transportation technologies, transformative travel modes, and shared mobilities used for regional planning.
