Platform Train Interface (PTI) Safety Detection System

TfL intends to directly award a contract for the delivery of a two-phase trial of a novel PTI safety detection system on the Piccadilly Line. The solution integrates ultrasonic sensors and video analytics to detect falls and obstructions at the platform edge. This approach has not previously been trialled in the London Underground operational context. The contract will cover both: • Phase 1 (Shadow Trial): A non-live environment test to validate the technology and integration approach. • Phase 2 (Operational Trial): A live deployment, subject to successful completion of Phase 1 and TfL's approval to proceed. The contract will be structured as a fixed-price, milestone-based agreement with a break clause following Phase 1.
