EIN4517 Central Florida Autonomous System of New York City Subways Questions I have two questions. I want someone please to help me. Also, I have attached the final report of our project on this semester because all questions based on the project that we did. Could you please help me to solve the questions and meet the expectation to all the questions.Please find my attachments for the questions and final report for the project. Based on your team’s project, what future problems might cause the system you have
designed once it is deployed? Explain.
Your major contractor has realized these future problems are a big concern and they have
decided to change the requirements right before the construction phase starts (there’s no
contract clause that prevents them from doing changes). They want the system to address
those issues as well. What do you need to include in your system? Include modifications in the
OpsCon (Mission, operating scenarios), requirements and architectures you will need to make
to satisfy the changes.

Executive Summary
For decades the city has desperately tried to find new transportation modifications to satisfy the
ever increasing demand of the subways. This report highlights a need for implementation of an
autonomous signaling system that revolutionizes how efficiently the subways run in New York
city. With this technology subway cars are tracked and displayed for passengers to see. Also
their speeds and routes are optimized to decrease delays.
Abstract
In a very modern world where people live in nowadays, there are various types of transportations
that are heavily relied on in a daily basis. These transportations have not only been hugely
developed all over the world, but also there are more and more that are invented and added to the
list. Mainly, airplanes, cars, motorcycles, buses, ships, subways, etc. This project will be
focusing on the latest transportation listed. Moreover, subway, in other words, urban
underground railway, has been out there not for a long while; in fact, it began in process in late
nineteenth century. To point out, among all the available large cities out there for this project to
consider, New York is the one that has been picked for this paper. There are many stakeholders
in New York city subway systems involved, and they have different perspective of seeing the
issue of the technology used for the subway system.
2.0 Problem
More and more people rely on the New York city subway to get them to their destination on time
and intact. However, passengers have to deal with outrageously long wait times that make them
late. Subway cars get constantly delayed due to poor signaling technology. With the old
3
signaling system subway cars have to drive slower or even stop because they are unsure of the
accurate gps location of other cars. Our new signaling system will increase the throughput of
passengers per hour and the overall efficiency. Subway cars will run at a faster speed without
sacrificing passenger’s safety. A lot of the conducting process is done manually but we want to
change it to a more automated process that tracks all subway cars remotely and can adjust their
speed automatically. Also the apps used will be available to passengers so they have an idea of
arrival times instead of being unsure.
3.0 Stakeholders:
–
Passengers: Experience delays from an outdated subway system.
–
Drivers: Traffic increases as people prefer to drive instead of using subway creating
hassles for drivers.
–
Environment: More cars being used as an alternative create more air pollution.
–
Government: Tourism is a major source of revenue, need a convenient method of
transportation.
–
Repairman: Subways have been used excessively for a while, and they require more
work than the new modified ones.
–
Train Conductor: Old technology creates greater risk to crashes.
–
New York Dept. of Transportation: More passengers willing to ride, greater revenue.
–
Pedestrians: People would rather walk resulting in overcrowding on sidewalks.
4.0. Subway system Operational Concept
4.1.
Vision
The vision of this signaling system in New York is to provide a better, reliable, profitable
and more accurate transportation by initiating a brand new signaling system.
4.2.
Mission Statement
The mission of this autonomous signaling system is to create and provide a high quality,
safely operated and efficient improvement to the old system. The system is developed to provide
4
superior operational performance at less operational cost. This will be done through updating the
signaling system to current technological standards that will be beneficial to everyone.
4.3
Operating Scenarios
1) Subway cars request service to travel to another station, receive feedback that its request is
accepted and it’s good to go. Receive input of planned route. Subway car request to start moving
following the planned road, receive feedback of traveling speed. Subway car approach to the first
stop, receive feedback of stopping signal.

2) Subway cars get feedback to pass the stopping signal, information technology department keep
track of them constantly, subway car approach to the next stopping signal, receives feedback to
pass and other train at the same stopping signal receive a feedback to stop.
3) Subway car request to speed up to maximum speed, receive feedback to maximize speed as
traveling and pass next stops.
4) Subway car slow down as it approaches station, subway car stop functioning and send signal to
inform it’s at the station, receive feedback to open doors, information technology collect.
5) Subway car approaches broken component. Control center tells conductor to assume control
and proceed with caution as they monitor other subway cars to avoid collisions. Once the train
passes faulty area control of the train goes back to automatic. Faulty area will be marked and
repairs will be made as soon as possible. Control center has to decide if area is deemed to high of
a risk to passenger’s safety.
6) Subway cars request service to travel to another station, receive feedback that its request is
accepted and it’s good to go. While traveling to the next stop it detects a disabled subway car up
ahead. Signal will turn to red and then the functioning subway car will diverted to a clear track.
