RSG seeks a talented and versatile travel demand modeler to assist with development and implementation of state-of-the-art regional truck models and supply-chain-based freight models in our White River Junction, Vermont office.


Your work involves travel demand model development, scripting, model implementation, analysis of results, documentation, and project management, with a specialization in modeling freight flows and commercial vehicle movements. As the ideal candidate, you are a team player who has a solid foundation in the theoretical concepts of commodity flows, supply chains, freight economics, and urban commercial vehicle behavior.

  • 2 to 5 years of experience developing and applying regional travel demand models, with a primary focus on freight, truck and commercial vehicle models
  • Experience estimating discrete choice models, count models and linear/non-linear regression models, using COT statistical estimation software (SAS, STATA, Matlab, ALogit) or open-source variants (R, Biogeme, Octave).
  • Strong scripting experience, for example with Python, R, JavaScript, GISDK, Cube
  • Strong verbal and technical writing abilities


  • Experience with commercial transportation modeling packages (EMME, VISUM, TransCAD, Cube)
  • Research and/or experience with supply chains and logistics models and freight economics
  • Research and/or experience applying mathematical programming and simulation models
