Do you have a passion for transportation?

Do you want to be a part of a team that truly enjoys designing solutions that are MAKING LIVES BETTER?

ATG is currently seeking a Senior Travel Demand Modeler. This position will be a key hire to help grow our practice.

Responsibilities:

The Travel Demand Modeler:

• Designs travel model architecture customized to meet transportation analysis objectives in the state or metropolitan area under study.
• Statistically analyzes household and transit onboard travel survey data to develop model parameters and estimate model.
• Defines variables, coefficients and constants to estimate a model likely to replicate observed transportation system travel behavior.
• Using iterative testing, calibrates the model coefficients to produce statistically reliable results to match target confidence and error levels based on project objectives.
• Using the calibrated model, validates the model to existing conditions to insure performance.
• Works with software designers / coders to develop macros and scripts to execute individual model components, manage input-output data handling among the models and provide a user interface to organize output data into exhibits and reports to provide results in a format designed to meet analysis objectives.
• Oversee application of models to forecast future transportation system performance under varying conditions and project scenarios to test the feasibility and economic viability of major highway and transit infrastructure projects.
• Produces and contributes to the presentation of technical memorandum, analysis reports and formal and informal technical presentations on model development, application, results and recommendations to a variety of groups including professional peers, policy makers and elected officials, civic and business leaders and the general public.

Required Qualifications:

• Bachelor's degree or higher in Transportation Engineering, Transportation Planning, or a closely related field.
• Minimum 10 years of experience working with travel demand models.
• Proficiency in at least one travel demand model environment with exposure to others (e.g. Trans CAD, Cube)
• Ability to plan, organize and manage the technical components of a travel demand modeling project.
• Demonstrated experience in the specification of travel demand model architecture.

• Ability to oversee computer programming related to travel demand modeling and traffic analysis.

• Creativity and skills integrating interdisciplinary knowledge from a variety of technical areas.
• Proficiency in carrying out travel demand model calibration and validation.
• Demonstrated experience with a variety of model applications supporting, metropolitan planning, statewide planning, transit ridership estimation and corridor analysis.
• Demonstrated expertise and experience in the production of model documentation and technical reports.

Desired Qualifications:

• Master's degree or higher in Transportation Engineering, Transportation Planning, or a closely related field.

• Proficiency in the use of statistical packages such as SPSS, SAS, MATLAB, STATA, R, Python

• Proficiency in the use of Nested Logit Model estimation packages such as ALOGIT or NLOGIT
• Ability to manage staff preforming computer programming with C , Python, R, C#/.Net, JavaScript, or similar.

• Experience supervising completion of tasks assigned to junior staff.
