Graduate Intern - Connected Vehicle (V2X) Communications Modeling and Traffic Simulation.

CO - Golden.

Intern (Fixed Term).

Job Description

The Advanced Computing Solutions Group in the Computational Science Center at the National Laboratory of the Rockies (NLR) has an opening for a graduate student researcher in connected and automated vehicle communications modeling, with an emphasis on data analysis and machine learning.

Vehicle-to-everything (V2X) communication lets vehicles talk to each other and to roadside infrastructure, and it is the backbone of cooperative driving automation. Field-testing V2X at the scale needed to see its effect on traffic would take hundreds of roadside units and thousands of equipped vehicles, which is cost-prohibitive, so simulation is the practical path.

The intern will work with NLR colleagues to analyze field V2X data and develop new V2X models for simulation.

We are looking for a motivated researcher with strong data and programming skills and an interest in the mission of NLR. The successful candidate will collaborate with NLR researchers.

Responsibilities include

• Clean, process, and analyze large-scale V2X field-test logs to characterize communication performance (e.g., packet delivery ratio, latency, and range) as a function of distance, device density, and environmental conditions.
• Help calibrate and validate microscopic LTE-V2X communication models against the field-test data.
• Develop and train machine-learning surrogate (approximate macroscopic) models of V2X behavior from large sets of simulation data, and evaluate their accuracy and computational efficiency.
• Write well-documented Python code and run workflows on NLR's high-performance computing systems.
• Document results and contribute to technical reports, presentations, and publications.
