Random-forest analysis of letter-carrier injuries
Canada Post analyzed 4.9 million employee-route-day records to identify injury risk factors
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
Takeaway
The model identified risk factors for safety planning. Canada Post did not report a resulting reduction in injuries.
