Job Description

Transportation Modeling Division

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 development studies, and air quality plans.

As regional planning needs, travel behaviors, and socioeconomic conditions change, the demands and expectations of our modeling program also 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 activity-based model (ABM) and an active transportation (AT) model. As the transportation systems are transforming, SANDAG is updating its ABM to respond to the impact of emerging transportation technologies, transformative travel modes, and shared mobilities used for regional planning.

Transportation Modeler Role

The Transportation Modeler will develop, maintain, and improve   existing transportation models including the activity-based model and the active transportation model. The Modeler will participate in adding features related to emerging technology, transformative mode, and shared mobility in travel modeling tools. This position also will coordinate project teams and modeling functions with other divisions and departments, committees, and outside agencies.

Job Responsibilities

This position is ideal for a transportation modeler with current, technical knowledge of modeling methods, software development, big data, and emerging transportation technologies. We anticipate significant career development will occur while working on the duties and responsibilities described below and through mentoring and close collaboration with senior staff and consultants.
