Transoft Safety Lab

Transoft Safety Lab was created to address the needs and challenges in research and practice in road safety.
Our mission is to contribute to knowledge generation in road safety through:

  • Providing a platform where the road safety community can research, develop and test new ideas in order to reduce fatalities and serious injuries.
  • Improving research through the cumulative efforts of Transoft Solutions experts, researchers from universities and research institutes, and road safety practitioners.
  • Disseminating new concepts and innovative solutions to improve and advance road safety knowledge and practices.

Collaborative Research

In an effort to keep surrogate safety research moving forward, Transoft is pleased to share data with academic researchers. Analysis results include CSV sheets containing conflict data using post-encroachment time (PET) and time-to-collision (TTC), road user counts and classification, speed data, and more.

Who is Transoft Safety Lab for?

Meet the Team

Transoft Safety Lab is only possible with the collaboration of worldwide leading researchers in the field, cities, and industrial partners paving the way for the shared goal of improving road safety.

The Transoft Safety Lab research and development team consists of:

Paul G. St-Aubin, P.Eng., Ph.D.

Paul is a licensed transportation research engineer located in Montréal, Québec, currently working as a Senior Product Manager at Transoft Solutions (ITS) and as a postdoctoral researcher affiliated with the University of Waterloo. He was also a postdoctoral researcher at IVADO/HEC Montréal. He specializes and is professionally interested in several civil engineering and computer science topics, particularly where these two intersect, including surrogate safety measures, driver behaviour, advanced collision detection, traffic data collection systems, and computer vision. He has also published several peer-reviewed journal and conference papers in the field of road safety and surrogate safety measures.


Alireza Jafari, Ph.D., RSP1

Alireza has a Ph.D. in Transportation Engineering and over 7 years of experience in road safety analysis. Before joining to Transoft Solutions, he was a postdoctoral fellow affiliated at Ryerson University. He specializes in developing statistical models to estimate crash frequency and crash severity. He has published several peer-reviewed journal and conference papers. His research on conflict-based crash prediction models has won national and international awards, including the best research and evaluation paper at the CARSP conference, 2019.

Bismarck Navarro, M.Eng.

Bismarck is a Ph.D. Candidate at McGill University and a project manager at Transoft Solutions. He has more than five years of experience in road safety analysis using proactive measures and over 10 years of project management. The areas of expertise of M.Eng. Navarro are users’ safety at intersections, user’s behaviour, traffic data technologies and computer vision analysis. He also has taught transportation engineering classes at McGill University and continues research and teaching proactive safety analysis.



Luis Miranda-Moreno, Ph.D

Luis is a professor at the civil engineering department of McGill University. His specialty is in transportation engineering with a focus on road safety, traffic monitoring and demand modeling, and sustainable transport strategies. His research interests include the development of crash-risk analysis methods, the integration of emergency technologies for traffic monitoring, the impact of climate on transportation systems, the analysis of short and long-term changes in travel demand, the impact of transport on the environment, the evaluation of energy efficiency measures and non-motorized transportation.
