Research Interests Supervised Students Code and Data Publications Talks Funding and Fellowships Availability Contact Information	Welcome to Nicolas Saunier's professional homepage. I am a full professor in transport engineering at Polytechnique Montréal in Canada (official page). You can find my CV (in French) and a short bilingual biography. I am a member of the Institute for Data Valorization (IVADO); the Interuniversity Research Centre on Enterprise Networks, Logistics and Transportation (CIRRELT) (I am co-head of the ITS lab of CIRRELT with Teodor Gabriel Crainic (UQàM)); the Interdisciplinary Research Centre on the Implementation of Sustainable Development ("Centre interdisciplinaire de recherche en opérationnalisation du développement durable", CIRODD); and the Québec network for research in road safety (RRSR). Prospective Students: I am always looking for graduate students who are interested in research in transport and computing (see my research interests: being able to prototype software to test your ideas, automate data processing and enable reproducibility is mandatory). Due to large volume of sollicitation by email, make sure to make a well articulated case for yourself and provide relevant information, or you will be ignored. Although all teaching is done in French at Polytechnique Montréal, you may write your thesis in English. News may be provided more regularly on Mastodon (@aphex_twin) and this blog.

Research Interests

My research interests focus on active and intelligent transport, road safety and data science for transport (data collection, storage, processing, analysis (machine learning), and visualization).

I am interested in really intelligent transport systems, i.e. systems that actually exhibit intelligent features such as adaptation to changing conditions with minimal supervising. Massive amounts of data are now collected continuously in our connected world, from geo-location devices in mobile phones to video sensors. If this data can be automatically analyzed, there are great opportunities for a better understanding and optimization of transport systems, from their management to user information. The field of computational transport science is thus emerging at the intersection of computer/data science and transport, to apply advanced data processing techniques to transport.

I am particularly interested in collecting and analyzing microscopic user data, e.g. trajectory data collected automatically using video sensors and computer vision techniques. This data can be interpreted automatically to learn and understand road users' behaviour and analyze road safety (without waiting for accidents to happen). I am also very interested in transport in general, in particular active transport, walking, cycling and public transit. Research on them has been typically limited, in particular in regard of their importance. The following is a list of keywords that are relevant to my research interests:

Transport keywords: intelligent transportation systems (inc. vehicular automation and driver assistance technologies), road safety, surrogate safety measures, interactions, traffic conflicts (near miss), risk of collision, exposure, simulation, utility cycling, walking, integration of transport and urban planning, placemaking.

Computing keywords: data science, computing, artificial intelligence, machine learning, algorithms, computer vision.

Finally, I am a supporter of open science for many reasons, both from a philosophical and moral point of view, and from a practical point of view. From a philosophical and moral point of view, it is the right thing to do, especially for publicly funded research institutions and it allows reproducible research: why should you trust my claims if you cannot replicate my work? From a practical point of view, it is a better method (open source software is a better software development technique) and my research benefits from collaboration and sharing code and data with you, as you reference my research and release publicly your improvements in turn). Join the movement!
