Enhancing subway reliability through MTA’s partnership with Google

The Metropolitan Transportation Authority (MTA) in New York City has partnered with Google for a groundbreaking pilot program focused on enhancing the reliability of its old subway network. Utilizing Google’s mobile technology, the effort aims to detect and resolve rail problems before they cause service interruptions. Named “TrackInspect,” the project signifies a considerable advancement in applying artificial intelligence and contemporary technology to public transportation.

The Metropolitan Transportation Authority (MTA) in New York City has teamed up with Google in an innovative pilot project aimed at improving the reliability of its aging subway system. By leveraging Google’s smartphone technology, the initiative seeks to identify and address track issues before they lead to service disruptions. Known as “TrackInspect,” the program represents a significant step forward in integrating artificial intelligence and modern technology into public transit.

“By spotting initial indicators of track deterioration, we not only cut down on maintenance expenses but also lessen inconveniences for passengers,” stated Demetrius Crichlow, president of New York City Transit, in an announcement made public in late February.

“By identifying early signs of track wear and tear, we not only reduce maintenance costs but also minimize disruptions for riders,” said Demetrius Crichlow, president of New York City Transit, in a statement released in late February.

Addressing delays using AI and smartphones

New York City’s commuters frequently encounter subway delays as a recurring issue. Towards the end of 2024, the MTA disclosed that tens of thousands of delays were occurring monthly, with December alone surpassing 40,000 incidents. These interruptions stem from multiple causes, such as track problems, construction activities, and crew shortages.

El programa TrackInspect se centra en abordar un aspecto crucial del problema: detectar y solucionar problemas mecánicos antes de que se agraven. Durante la prueba piloto, se instalaron seis teléfonos Google Pixel en cuatro vagones R46 del metro, reconocidos por sus asientos de color naranja y amarillo. Los dispositivos registraron 335 millones de lecturas de sensores, más de un millón de datos de GPS y 1,200 horas de audio.

Los teléfonos inteligentes se colocaron estratégicamente tanto dentro como debajo de los vagones del metro. Los dispositivos externos estaban equipados con micrófonos para captar sonidos y vibraciones, mientras que los internos tenían los micrófonos desactivados para evitar grabar conversaciones de los pasajeros. En cambio, estos dispositivos se concentraban únicamente en las vibraciones para identificar anomalías en las vías.

Rob Sarno, serving as an assistant chief track officer for the MTA, was integral to the project. His duties involved examining audio clips that the AI system flagged for potential track issues. “The system pinpoints zones with unusual decibel levels, possibly signaling loose joints, damaged rails, or other defects,” Sarno elaborated.

Rob Sarno, an assistant chief track officer with the MTA, played a key role in the project. His responsibilities included reviewing audio clips flagged by the AI system to identify potential track issues. “The system highlighted areas with abnormal decibel levels, which could indicate loose joints, damaged rails, or other defects,” Sarno explained.

Encouraging outcomes, yet challenges persist

Promising results but hurdles remain

The initiative also featured an AI-driven tool based on Google’s Gemini model, enabling inspectors to inquire about maintenance procedures and repair records. This conversational AI furnished inspectors with straightforward, actionable insights, which further streamlined the maintenance workflow.

A pesar de su éxito, el programa piloto plantea dudas sobre su escalabilidad y coste. La MTA no ha revelado cuánto costaría implementar TrackInspect en todo su sistema de metro, que abarca 472 estaciones y atiende a más de mil millones de pasajeros cada año. La agencia ya se enfrenta a desafíos financieros, necesitando miles de millones de dólares para completar proyectos de infraestructura en curso.

Despite its success, the pilot program raises questions about scalability and cost. The MTA has not disclosed how much it would cost to implement TrackInspect across its entire subway system, which includes 472 stations and serves over one billion riders annually. The agency is already grappling with financial challenges, needing billions of dollars to complete existing infrastructure projects.

An increasing movement in transit advancements

A growing trend in transit innovation

New York’s partnership with Google is part of a broader trend in which cities worldwide are adopting artificial intelligence and smart technologies to improve public transit systems. For example, New Jersey Transit has used AI to analyze passenger flow and crowd management, while the Chicago Transit Authority has implemented AI-driven security measures to detect weapons. In Beijing, facial recognition technology has been introduced as an alternative to traditional transit tickets, reducing wait times during peak hours.

Google itself has collaborated with other transportation agencies in the past. The tech giant has developed tools to enhance Amtrak’s scheduling and partnered with parking technology providers to integrate street parking data into Google Maps. However, the scale and complexity of New York’s subway system make this project particularly ambitious.

Future Prospects

Although the TrackInspect pilot has concluded, the MTA is investigating collaborations with additional technology providers to further improve its maintenance procedures. The agency is also evaluating data from the pilot to assess its effects on minimizing delays and enhancing service. Initial signs indicate that specific types of delays, including those from braking problems and track defects, declined on the A line during the pilot. However, the MTA warns that more analysis is required to verify a direct connection to the program.

While the TrackInspect pilot has ended, the MTA is exploring partnerships with other technology providers to further enhance its maintenance processes. The agency is also analyzing data from the pilot to determine its impact on reducing delays and improving service. Early indications suggest that certain types of delays, such as those caused by braking issues and track defects, decreased on the A line during the pilot period. However, the MTA cautions that further analysis is needed to confirm a direct link to the program.

Reflecting on the project, Sarno highlights the promise of AI-driven solutions to revolutionize public transit. “This technology enables us to identify issues sooner, act more swiftly, and ultimately offer improved service to our passengers,” he stated.

As Sarno reflects on the project, he emphasizes the potential of AI-driven solutions to transform public transportation. “This technology allows us to detect problems earlier, respond faster, and ultimately provide better service to our customers,” he said.

The MTA’s collaboration with Google underscores the potential of public-private partnerships to drive innovation in critical infrastructure. Whether TrackInspect becomes a permanent fixture in New York’s subway system remains to be seen, but its success highlights the possibilities of integrating cutting-edge technology into the daily lives of commuters.
