Signaling Challenge

How can we modernize the subway signaling system faster and at lower cost?

MTA subways are controlled by an aging signaling system. By digitizing this signaling system, the MTA can safely and reliably run more subways cars more closely together, increasing capacity and making travel more enjoyable.

This challenge called for technology to implement a more efficient, reliable subway signaling system quickly and cost-effectively.

Signaling Challenge Criteria

MTA subject matter experts and private sector judges will evaluate applications to the signaling challenge according to the following criteria:

  • Impact: technology can be piloted within two years in the MTA operating environment, the Submission presents a viable solution relevant to the Signaling Challenge, and has the potential to advance signaling program objectives:
    • improved safety of passengers and staff
    • on-time performance
    • increased customer satisfaction
    • enhanced operational flexibility
    • on-time and on-budget infrastructure program delivery
  • Product: technology is in prototype or more mature phase and available for live demonstration, Applicant is able to provide customer metrics or other evidence illustrating market fit and success in other markets, and solution can use non-proprietary standards and data that support interoperability with other technologies
  • Team: Applicant has a qualified, compatible team with dedicated financial and technical resources to execute a successful pilot
  • Value: technology presents (a) a new way of deriving more value from existing MTA assets, (b) potential cost savings for the MTA or a new revenue source, and (c) an opportunity to more efficiently manage infrastructure, operations and/or customer service
