Travel Demand Modeler

Alliance Transportation Group (ATG) delivers a full range of engineering, planning, and consulting services to address current and future transportation challenges.

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 Travel Demand Modeler. This position will be a key hire to help grow our practice.

The selected candidate will:

• Assist with the designs of 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 in order to develop model parameters and estimate model.
• Works with and creates CUBE Voyager and TransCAD GISDK scripts.
• Performs computer programming related to travel demand modeling and traffic analysis.
• Conducting statistical analyses of travel survey and passively-collected transportation data.
• Defines variables, coefficients, and constants to estimate a model likely to replicate observed transportation system travel behavior.
• Perform GIS analysis using ArcGIS, TransCAD or QGIS
• 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.
• 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.
• Applies the 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 5 - 8 years of experience working with travel demand models.
• Proficiency in at least one travel demand model environment with exposure to others (e.g. TransCAD, Cube)
• Scripting experience with Python (pandas, NumPy), R, VB, GISDK, or similar
• Ability to plan, organize and manage the technical components of a travel demand modeling project.
• Specific technical training in and experience with statistics and statistical packages, geographic information systems (GIS), travel demand models.
• Experience in carrying out travel demand model estimation, calibration and validation.
• 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.
• Familiarity with GTFS, Dynameq, TransModeler
• Demonstrated experience in the specification of travel demand model architecture.
• Proficiency in the use of statistical packages such as SPSS, SAS, MATLAB, STATA.
• Proficiency in computer programming with C++, Python, R, C#/.Net, JavaScript, or similar
• Experience supervising completion of tasks assigned to junior staff.
