The NYCT subway punctuality is a key performance measure for the Operational Planning department. The traditional schedule timesheet and manual “punch in” method can’t meet the requirement of quick reaction upon the unexpected train delay. Mr. Reddy and his team developed the real-time Time-Space diagrams to mitigate this...
As data collection for public transportation improves and customers’ appetite for information grows, there has been a growing interest in performance measurement systems that better reflect customer experience and quantify the impacts of service while accounting for ridership. A fair amount of research has been dedicated to developing...
The signal system on NYC Transit’s “B” Division (with the exception of CBTC on L line) was installed in phases during the Great Depression and currently in the process of modernization and would take a few more years. All signals operated on relay logic and it was impossible...
The New York City metropolitan area was hard hit by COVID-19, and the pandemic brought with it unprecedented challenges for New York City Transit. Previously dependable approaches to monitor ridership suddenly became unavailable (e.g., local bus payment data, field checks). We were tasked to quickly modify existing processes to...
Mr. Glikin led a department of 30 transit professionals scheduling bus service for a large transit system with 20 bus garages. Over time, Mr. Glikin led a successful transformation of the personnel roster from primarily individuals promoted from first level bus operations supervisor roles, with substantial operating experience,...
A large transit agency’s cost of operations per passenger, per hour, and per mile was discerned to be very high. It sought to explore how practices differed from other operators. Understanding how one’s own system performs against similar peer properties is valuable in deciding on changes in transit...
The installation of an Automated Vehicle Location (AVL) system alongside existing Automated Fare Collection (AFC) data on all New York City buses spurred development of a city-wide bus passenger boarding and alighting ridership model. These advances in ridership modeling allowed for analysis of trip passenger loads and 100%...
Amid significant increases in ridership (9.8% over the past 5 years) on the more than 100 year-old New York City Transit (NYCT) subway system, NYCT has become aware of increased crowding on station platforms. Because of limited platform capacity, platforms become crowded even during minor service disruptions. A...
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...
We were tasked to examine bus lanes in New York City for differences in enforcement needs based on actual bus speed data from GPS-based automated vehicle locator (AVL) systems. In New York, bus lanes are utilized for a number of different purposes, such as hosting right turn traffic,...
