Movement has a human cost

The challenge

A transport system must be judged by safety as well as speed. Understanding risk involves road design, exposure, vehicle safety, enforcement and emergency response, with attention to people walking or cycling.

What the number does—and does not—say

This is the global estimate used in the 2023 report, not a live count. Later WHO estimates may differ. National reporting and estimation methods must be checked before local comparisons.

A question worth investigating

Which routes combine high exposure with weak protection for vulnerable road users?

Labs research direction: start with a defined population and location, review the source methodology, and validate assumptions with people working in the sector. This question is our interpretation; the statistic alone does not establish causes or prove a particular solution.
