Blue Island residents face a mix of traffic, pedestrian activity, and construction-adjacent risk that doesn’t always show up in national “typical case” models. For example, an online tool may not account for:
- Crash scenes involving pedestrians or cyclists (visibility, crosswalk timing, sidewalk conditions)
- Multi-vehicle collisions on commute corridors where fault can be disputed
- Late-discovered complications after an injury (what doctors documented, and when)
- Work-related hazards for families whose loss involves industrial or service employment
When those details don’t fit the calculator’s assumptions, the number you see can be off in either direction.
