Knowledge of the root causes of delays in transit networks has obvious value; it can be used to direct resources toward mitigation efforts and measure the effectiveness of those efforts. However, delays with indirect causes can be difficult to attribute, and may be assigned to broad categories that...
Over two million trips are taken every weekday across the New York City Transit (NYCT) bus network. Revising the schedules for each of these routes is a labor-intensive process, and, thanks to limited resources, fewer than half of all routes are examined each year. Traditionally, schedules have been...
SIRE is a web-based real-time decision support tool for dispatchers in the Rail Control Center (RCC). It assesses the current locations and movement patterns of trains, factors in typical ridership patterns, and recommends actions dispatchers should take (e.g., holds, skips) to improve service to maximize the benefit to...
The Reddy Analytics team members were instrumental in providing irrefutable evidence from signal system data that demonstrated the dramatic and immediate impact of recalibrating “grade timers” on one of the busiest rapid transit systems in the nation. At the time, there was a debate internal to the transit...
We were tasked by a major commuter rail operator to analyze ticket sales data to determine ridership with origin-destination and time-of-day detail. The operator had four distinct sales channels: mobile ticketing, paper ticket vending machines, monthly direct-mail ticket subscriptions, and on-board sales by train crew. The mobile ticket...

Outside the railroad industry, passenger trip times are often treated as a performance measure or yardstick of the industry’s health. However, many factors not known or well understood by casual observers affect trip times—indeed, some are recognized techniques utilized by infrastructure owners to deliver journey time reductions. Factors...
The eight-step framework consisting of organization, procedure, personnel, time study, rate analysis, utilization analysis, rightsizing, and benchmarking is used to understand and improve productivity and efficiency of railroad cyclical curve rail replacement processes at a major Northeastern commuter railroad. The Railroad is organized into eight geographical maintenance subdivisions...
At a major regional railway, we were responsible for developing staffing, organizational structure, and business plans necessary to initiate a companywide Enterprise Geographic Information Systems (GIS) program. We implemented corporate GIS standards, boilerplates, policies, and procedures, and managed the initial bootstrapping phases of the new program, ensuring that...
Triggered by both Superstorm Sandy aftermath and a minor operational incident—where accurate and rapid mapping would have been tremendously helpful—Metro-North Commuter Railroad deployed its first Enterprise Geographic Information System (GIS) in 2012 by federating existing departmental systems, creating a companywide Office of GIS Coordination, promulgating GIS policies and...
