TIRF Announcements

Joint TIRF / SMATS webinar on April 30, 2026: 1pm – 2:00pm EST / 10am – 11:00am PST.

Brought to you by:

Lowering posted speed limits is a common Vision Zero strategy, but its effectiveness can vary significantly by roadway type and operating context.

Join SMATS and TIRF for a webinar sharing findings from a multi-city Canadian study conducted using connected vehicle data. The session will cover:

• Observed changes in vehicle speeds following posted speed limit reductions
• Where reduced limits may be effective on their own, and where additional measures may be needed
• A practical framework to help assess whether a speed limit reduction is likely to be effective in a given context
• A predictive statistical model to help estimate future collision risk using floating car and roadway data

This webinar is for professionals across road safety, transportation engineering, planning, policy, and municipal operations who are looking for more data-driven and defensible ways to evaluate speed management strategies.
