San Diego Association of Governments - SANDAG
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 transportation model (ABM) and an active transportation (AT) model, and is in the process of developing an advanced, integrated, dynamic traffic assignment (DTA) model. SANDAG also is updating the ABM using the 2016/2017 San Diego household travel behavior survey and Transit onboard survey for the next Regional Transportation Plan. Transportation Modeler Role The Transportation Modeler will develop, maintain, and improve SANDAG transportation modeling tools including the activity-based model, active transportation model, and the dynamic traffic assignment model. 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 an experienced transportation modeler with current technical knowledge of modeling methods, software development, and maintenance. We anticipate significant career development will occur while working on the types of duties and responsibilities described below and through mentoring and close collaboration with senior staff and consultants. Examples of primary responsibilities may include: Perform various research, analysis, and technical duties related to the maintenance and improvement of complex models such as the activity-based (ABM) model, active transportation (AT) model, and dynamic traffic assignment (DTA) model used to support regional transportation planning. Ensure transportation modeling tools and analytical capabilities are credible and effective for policy analysis; participate in quality assurance and quality control processes; participate in processes to improve model transparency. Develop and maintain custom software applications to support travel forecast modeling; develop new software and scripts, refactor existing software, and create new architectures as modeling needs evolve. Participate in the development of Request for Proposals (RFP’s), evaluate competitive project proposals and make recommendations for consultant selection; coordinate with project consultants and ensure projects are completed on schedule, within the prescribed budget, and with a high-level of effectiveness. Coordinate with Model Application staff to support transportation modeling and analysis required for long-range regional plans, transit system implementation and analysis, corridor studies, air quality conformity analysis, and major highway and transit investment studies. Coordinate the integration of transportation and land use models, and coordinate with economic and demographic research staff to determine data interactions and conduct model scenario testing. Coordinate with the Data Solutions team to maintain transportation databases; ensure current and accurate traffic and passenger count data are being used, gather and process traffic count data from Caltrans PeMS, Caltrans traffic census counts, local arterial counts, and transit ridership data, and existing and planned transit and highway network assumptions; coordinate the GIS process to update databases. Coordinate and collaborate on inter-departmental and inter-agency project teams assembled for transportation modeling, analyses, and planning; foster collaborative working relationships with local jurisdictions and the various transit and transportation agencies. Collect and process quantitative data from local, state, and federal agencies, including Census, American Community Survey (ACS), Public Use Microdata Sample (PUMS), California Household Travel Survey (CHTS), and NHTS (National Household Travel Survey); ensure quality control of data and surveys related to model development and improvements. Process model calibration and validation of third party data sources, such as INRIX speed data, Airsage origin to destination (OD) trips, ATRI truck data, and StreetLight OD data.
