Job Description
We are seeking a Travel Demand Modeler to estimate calibrate and apply statewide and urban area multimodal travel demand models for State Departments of Transportation and Metropolitan Planning Organizations throughout the U.S.
Responsibilities:
- 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 inputoutput 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.
