Transcribed Image Text:Developing a Smart City Traffic Management System (SCTMS): Scenario
A city government is implementing a Smart City Traffic Management System (SCTMS) to reduce
congestion, enhance traffic flow, and improve road safety. The system will incorporate real-time
data from traffic sensors, manage signal timings, provide route suggestions to drivers, and allow
emergency services to access priority routes. The SCTMS must be integrated with existing urban
planning systems, scalable for future expansions, and secure to protect sensitive traffic and user
data.
QUESTION 4
For SCTMS to align with urban infrastructure and address future needs, a structured design methodology is
required. Answer the following questions to explore its implementation.
4.1 Explain how data flow diagrams (DFDs) can be employed to depict how information moves
through SCTMS modules like sensors, traffic signals, and the central control system.
4.2 Identify 5 (five) critical analytical skills that a systems analyst should possess to evaluate and
refine complex city traffic data in SCTMS.
4.3 How can a relationship diagram aid in structuring key data points within the SCTMS, such as
vehicle counts, traffic signal timings, and emergency vehicle routes?
4.4 Describe how joint application design (JAD) sessions can be used to collaborate with city officials
and traffic management experts to refine SCTMS requirements.

PTC uses wireless communications to relay visual and audible data to train crew members regarding when the train needs to be slowed or stopped. This guidance is based on several factors, including the train’s location and speed, as determined by GPS, track geometry, the status and position of approaching switches, and speed limits at approaching curves, crossings, and other speed-restriction areas. PTC communicates with the train’s onboard computer, which audibly warns the engineer and displays the train’s safebraking distance, based on conditions at that time. Should the engineer fail to respond appropriately, the…arrow_forward
