DTU Management’s Transport Division would like to invite applications for a 3-year PhD position. The successful candidate will join the Machine Learning for Smart Mobility Group and will work under the supervision of Associate Professor Filipe Rodrigues and Associate Professor Carlos Lima Azevedo.

This PhD project is part of a project entitled “Proactive traffic control through AI and Big Data”, funded by the Danmarks Frie Forskningsfond.

Project Background
Reinforcement learning (RL) constitutes a promising solution for alleviating the problem of traffic congestion and associated greenhouse gas emissions by producing adaptive traffic signal controllers that outperform conventional systems. However, the existing solutions are merely reactive. This project aims at developing a new generation of proactive traffic control approaches by integrating into a RL framework a novel fully-Bayesian context-aware traffic prediction model that can forecast the future evolution of traffic and provide uncertainty estimates for its predictions, while accounting for contextual information (e.g. about planned events, incidents and weather), traffic network flow theory and the traffic signal control actions. The core idea is that, by accounting for the effects of external factors on future traffic conditions, the RL agent can learn to be proactive and take preemptive measures to alleviate (or even mitigate) future congestion scenarios and reduce emissions.

The successful candidate will explore new machine learning methods, particularly reinforcement learning, deep learning, and Bayesian modelling, for traffic signal control, which will be tested in highly realistic simulation scenarios to be implemented by the candidate in an existing open-source state-of-the-art mobility, energy and emissions micro-simulation tool during the initial stage of the PhD.

Together with our team (with a background in machine learning, reinforcement learning, Bayesian modelling and microscopic traffic simulation) the candidate will extend current microscopic traffic simulation models and then develop context-aware transport prediction models and model-based reinforcement learning solutions towards proactive real-time traffic signal control policies.

We are looking for excellent applicants with MSc background on Computer Science, Machine Learning, Transportation, Applied Statistics or related.

Responsibilities:

• Set-up realistic scenarios using an open-source state-of-the-art mobility, energy and emissions micro-simulation tool.
• Develop context-aware transport prediction models.
• Develop spatio-temporal models of the evolution of the traffic conditions given the traffic control actions.
• Implement and thoroughly test model-based reinforcement learning approaches for traffic signal control.
• Collaborate with researchers from machine learning and transportation in a truly interdisciplinary environment.
• Co-author scientific papers aimed at high-impact journals.
• Participate in international conferences.
• Take advanced classes to improve academic skills.
• Carry out work in the area of dissemination and teaching as part of the overall PhD education.

Qualifications: 

• A MSc degree (120 ECTS points) in Computer Science (Machine Learning or Simulation), Transportation, Applied Statistics or related.
• Great programming capabilities in at least one scientific language is required.
• Experience with machine learning is required.
• Good background in statistics and probability theory is required.
• Good programming capabilities in both Python and C, C++ or C# are preferred.
• Experience with reinforcement learning and/or traffic simulation is favoured.

The following soft skills are also important:

• Curiosity and interest about current and future mobility challenges and digital technologies.
• Good communication skills in English, both written and orally.
• Experience in writing and publishing scientific papers is an advantage.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
