The Transit Tech Lab initiative aimed to enhance security and operational efficiency across New York regional transit infrastructure by integrating advanced under-vehicle and under-train surveillance systems. The challenge was to deploy ISS’s SecurOS® UVSS and UTSS technologies to detect explosives, contraband, and mechanical defects, while providing real-time data on vehicle flows and checkpoint efficiency. The project required seamless integration with existing infrastructure at high-traffic locations, such as the World Trade Center and NJ TRANSIT facilities, and had to accommodate diverse use cases across multiple transit agencies to improve overall safety, resilience, and maintenance processes.
