Potential Problems during lifetime:
Incomplete Software Update
Risk: Software update sent to system containing bugs and errors that compromise the signaling system. Leading to faulty signaling or rendering traffic light unable to function.
Solution: Enforce strict testing and quality assurance on updates sent to the system.
Sensor Failure
Risk: Some sensors may not work due to issues related to weather, software, or traffic. This will lead to faulty signaling and timing in the intersection.
Solution: Have backup sensors set up in case of failure and report sensor failures to the agency that supervises transportation within the city.
Cybersecurity Risk
Risk: System software is compromised and traffic light no longer functions properly.
Solution: Ensure high authentication to access system and ensure strict cybersecurity measures.
