The Transit Analytics Lab (TAL) of the University of Toronto brings together transportation and technology researchers from across the University of Toronto, transit systems in the Golden Horseshoe area, and private sector technology providers and consultants.

Among its objectives are to: foster innovation in transit data-driven tools (analytics) using advanced methods of data science, machine learning, artificial intelligence, simulation and statistics; expose the professional community through knowledge transfer activities to advanced analytics; build collaborations with public and private organizations; and establish U of T as a national and international leader in transit data analytics.

TAL was launched in 2020 with the International Symposium on Automated Transit Data. Since then, TAL has organized workshops and has been involved in a number of research pursuits, many of which have practical applications.

The time is appropriate to host our annual TAL Research Day workshop that will provide a high-level overview of the many research activities being pursued by the TAL team; please see the Draft Program below.

The TAL Research Day will be held virtually and is free, though registration is required.
