WorkingCompany's own claimOfficial ↗

Problem

Canada Post needed to understand which working conditions were associated with letter-carrier injuries. Injuries were relatively rare, creating an imbalanced classification problem.

Approach

Its analytics team used a random-forest model to examine employee and route characteristics alongside weather. The analysis identified carrier tenure, near-freezing temperatures and walking distance as important risk factors.

Results

4.9 millionemployee-route-day records in the injury analysis, according to Canada PostCompany's own claim[1]

Takeaway

The model identified risk factors for safety planning. Canada Post did not report a resulting reduction in injuries.
