Recovery from COVID-19 and Sustainability are the two critical topics facing public transportation in Greater New York during Transit Innovation Challenge in 2022. Apital contributed two innovative conceptual projects for both Recovery and Sustainability topics. The project proposal of W3@Train, a Centralized Train Diagnostic System (CDTS) to address sustainability, and W3@Limit, a Track Intrusion Detection System (TIDS) to address Recovery. Apital is happy to contribute to the transit community and provide fresh ideas to improve the railway system.
