traffic collision
Let an agent explain traffic collisions and their kinds, relay causes, statistics and prevention from road safety sources with attribution, route people at a crash to emergency services, and distinguish road collisions from rail accidents as a related category and from non-collision crashes.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain traffic collisions and their kinds, relay causes, statistics and prevention from road safety sources with attribution, route people at a crash to emergency services, and distinguish road collisions from rail accidents as a related category and from non-collision crashes.
An event in which a road vehicle collides with another vehicle, a pedestrian, an animal or an obstacle, including side collisions, lane departure crashes and pedestrians hit by cars, and, in the registry s broader sense, rail collisions such as tram accidents and the major postwar Japanese National Railways accidents; traffic collisions are a leading cause of death and injury worldwide and are addressed by road safety engineering, law and vehicle design. Anyone at a crash should call emergency services first.
What it is for: Not applicable; a category of accident.
It can be route emergencies first; explain kinds and causes; relay statistics and prevention; distinguish related events.
Distinguishing features
Vehicle collision
Leading injury cause
Preventable
Engineering and law responses
What it looks like
Not a visible object; damaged vehicles at a crash scene.
Physical character
road deaths worldwide: about 1.19 million per year - WHO 2023
injuries: 20-50 million per year - estimates
leading cause of death: ages 5-29 note
How it is recognised
Collision involving road vehicles
Side collision, lane departure, pedestrian hit by car; rail and tram collisions as related aliases
Rollovers without collision are non-collision crashes; rail accidents are a separate domain

- How should road safety sources be linked?
- The registry entry has merged aliases naming rail and tram events; should they be split off?
