DTU Management’s Transport Division would like to invite applications for a 3-year PhD position starting no later than 1 January 2023. The successful candidate will join the Machine Learning for Smart Mobility Group and will work under the supervision of Associate Professors Carlos Lima Azevedo and Filipe Rodrigues.

The successful applicant will work on research which is focused on the development of next-generation large-scale mobility simulation and the use of new machine-learning techniques in the design of combined energy-transportation demand management schemes.

We are looking for excellent applicants with MSc background in Computer Science, Transportation, Applied Mathematics, Environmental or Electric Engineering and Operations Research with the interest and ambition to pursue PhD studies in the field of applied simulation and machine learning.

This position is funded under the DTU-KTH Alliance and a collaboration with Professors Erik Jenelius and Zhenliang Ma, from the Department of Civil and Architectural Engineering of KTH Royal Institute of Technology, Sweden, is planned including a 6 month stay at KTH.

Project Background
Recent technological and business advances have supported the rise of new shared on-demand mobility services (such as ridesharing, micro-mobility, etc) that promise opportunities for improved accessibility. However their integration with classical transit systems continue to challenge the existing planning and operations and to understand the full potential gains in welfare for complex transportation systems of the future. Beyond these, the increasing electrification of transport requires a holistic approach to planning and managing the coupled transportation and power networks with cleaner energy.

This project focuses on the following central question: How to design an efficient and sustainable electrified integrated transit ecosystem that aligns the needs of the individual traveler, and creates values for providers of both transit and on-demand services, and society as a whole?

The DREMTS project explores the concept of demand-responsive electrified multimodal transit systems and develops data-driven network design, and operation control and management methodologies. DREMTS combines high-occupancy electrified vehicles (buses or trains) with electric on-demand mobility services under a mobility-as-a-service framework, and builds new planning and operation algorithms targeting both the mobility operators, the individual user and energy providers.

The project includes 4 threads of research: (1) combined mobility and energy network design; (2) energy and transit cooperative algorithms for shared-mobility fleet operations; (3) prediction of individual behaviour under Mobility-as-a-Service (MaaS) and design of dynamic pricing and incentive mechanisms at the trip and individual level; (3) large-scale agent-based simulation platform to validate the new generation of algorithms.

Together with our team (with a background in machine learning, reinforcement learning, Bayesian modelling and microscopic traffic simulation), the successful cadidate will focus on the research thread (3) and (4) above, namely:

  • Extend an open-source large-scale urban mobility simulators (SimMobility) with energy supply simulation and build a realistic large-network case.
  • Explore new machine learning methods, namely reinforcement learning, for the design of pricing and incentivive algorithms at the individual and trip level within a MaaS setting.

The successful candidate is also expected to collaborate with the PhD student at KTH that will work on research threads (1) and (2).

DREMTS aims at significant sustainability impacts in the decision making process of the next generation multi-modal public transportation systems. Several MaaS initiatives and public transportation electrification have been initiated around the world and DREMTS will support directly such initiatives in Denmark, Sweden, and beyond.

Responsibilities and tasks

  • Conduct a literature review and learning in large-scale mobility and energy simulation frameworks.
  • Perform mathematical model formulation and estimation using statistical methods;
  • Code implementation and validation for these models within the context of a simulation environment.
  • Design, implement and thoroughly test model-based reinforcement learning approaches for pricing and incentives.
  • Design, implement and thoroughly test personalization algorithms.
  • 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 teaching, teaching support and BSc./MSc. co-supervision as part of the overall PhD contract.

Qualifications
We require the following:

  • MSc background on Computer Science, Transportation, Applied Mathematics, Environmental or Electric Engineering and Operations Reseaerch, Industrial Engineering or related is required;
  • Excellent background in statistics and probability theory is required.
  • Good programming capabilities, in C/C++/C# and at least one scientific language (e.g. Python, Matlab, R, Julia) are required;
  • Experience with machine learning is preferred.
  • Experience with reinforcement learning and/or traffic simulation is favoured.
  • Transportation Modelling disciplines in the education background are preferable;

The following soft skills are also important:
