February 13, 2026 - 02:41

Following a series of violent incidents on trains and buses, the Chicago Transit Authority is moving forward with plans to significantly expand its use of artificial intelligence gun detection technology across its system in the coming weeks. The initiative aims to enhance passenger safety by identifying potential threats in real-time.

The system utilizes advanced sensors and algorithms to scan for concealed weapons as passengers enter stations. When a potential firearm is detected, the technology alerts security personnel, who can then intervene appropriately. Officials emphasize that the AI is designed to identify weapon shapes and does not involve facial recognition or individual profiling.

This expansion comes amid ongoing public concern regarding safety on public transportation. Transit authorities state that the technology acts as a force multiplier, allowing security teams to respond more effectively to potential dangers before situations escalate. The rollout is part of a broader, multi-layered security strategy that includes increased personnel and physical infrastructure improvements. The CTA asserts that the primary goal is to create a stronger deterrent against violence and to reassure the riding public of their safety while using essential transit services.
