Transportation Engineer ll​/lll, Model

Summary:

The Transportation Engineer performs regional transportation planning activities for the metropolitan Washington region, such as applying the COG/TPB Regional Travel Demand Forecasting Model, the U.S. Environmental Protection Agency’s (EPA’s) mobile emissions model (MOVES), or developing inputs for these two models, such as zone-level land use data, transportation networks, or information about the motor vehicle fleet. This is a technical position requiring strong quantitative skills and an ability to analyze and interpret technical data, thus also requiring familiarity with transportation planning, air quality planning, and travel demand forecasting.

This person should be passionate about learning, improving technical skills, public service, and making significant contributions that will improve the agency and the region. Work is performed under the general supervision of a higher-level transportation engineer/program manager, but the candidate should exhibit a certain degree of independence and self-direction, especially at the Transportation Engineer III level.

EXAMPLES OF WORK

• Development of travel demand model inputs and MOVES model inputs, such as the transportation networks and land use data, for air quality planning, project planning and scenario planning activities.
• Running and occasionally updating the regional travel model.
• Analysis and troubleshooting of the travel demand model, the EPA MOVES mobile emissions model, and other model output in support of the air quality conformity analysis, the Long-Range Transportation Plan (LRTP) performance assessment and scenario/project planning.
• Providing network development and travel demand modeling assistance related to other air quality planning activities, including state implementation plans (SIPs) for addressing federal air quality standards.
• Conducting reasonableness reviews of various technical data related to air quality conformity and other studies.
• Preparation of project maps using geographic information system (GIS) software.
• Exploration and implementation of tools used for scenario and sketch planning analyses (e.g., Vision Eval).
• Writing technical memoranda and reports.
• Becoming knowledgeable with federal regulations and guidance pertaining to air quality planning.
• Making presentations to the TPB Technical Committee, Travel Forecasting Subcommittee (TFS) and other related committees.
• Supporting data requests from outside parties related to the regional travel demand model and EPA’s MOVES model, and/or their inputs.
