TRAFFIC SAFETY & ITS SOLUTIONS

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.

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, Ph.D., 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.

ADVISOR

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.

JOIN US FOR THIS SPECIAL EVENT

Transoft Safety Lab in collaboration with iTSS Lab is hosting its second virtual Road Safety Research Workshop, “Vulnerable Road Users (VRU) Safety: Alternative Approaches and Practical Applications.”

The event being held on Wednesday, December 1, 2021, will feature presentations by Dr. Marie-Soleil Cloutier, professor at INRS UCS and scientific director at Pedestrian and Urban Space Laboratory (LAPS), Dr. Thomas Götschi, researcher at the University of Oregon who leads the development of HEAT project for walking and cycling for World Health Organization, and Dr. Matin Nabavi Niaki, cyclist safety researcher at SWOV (the National Scientific Institute for Road Safety Research, Netherlands).

Further Reading

Development of Crash Risk Prediction System for the Regional Municipality of Durham In partnership with the Autonomous Vehicle Innovation Network (AVIN) led by the Ontario Centre of Innovation (OCI) and the Regional Municipality of Durham

The project will extend the core capabilities of Transoft’s automated road safety solutions to allow collision courses between road users to be predicted in real-time. The system will include near-miss notification alerts and a system for forecasting long-term safety problems.

Rural Road Merge Lane Analysis and Scooter and Cyclist Safety in Europe
In partnership with the Austrian Institute of Technology

Transoft Solutions is working with the Austrian Institute of Technology to analyze rural road merge lanes in Lower Austria in order to evaluate merging maneuvers, merging conflicts, and accelerations. In addition, the Institute and Transoft Solutions are working on projects focused on push scooter, e-scooter and cyclist safety and behavior in Austria, Switzerland, and Germany.

Before-After Analysis of Roundabouts and Intersections in Addis Ababa, Ethiopia In partnership with the World Bank Group

Transoft Solutions analyzed a total of 25 intersections and roundabouts in Addis Ababa Ethiopia for conflict risk and severity. The World Bank Group is using the data to determine and implement changes at the sites, after which point an “after” study will be completed to evaluate the change in safety.

Before-After Analysis of Intersection Redesign for Cyclists in The Hague, Netherlands In partnership with SWOV Institute for Road Safety Research

The project consisted of an analysis of two intersections in The Hague, the Netherlands before and after the redesign of painted bike lanes. Based on the analysis, the countermeasures implementations were found to be successful in reducing collision risk and severity.
