vedant3642/Traffic_Management_System_VK ? reverse-engineered prompt

Build me a traffic management web app that uses AI to watch traffic video, count vehicles in real time, and adjust signal timing based on how busy each lane is. I want a live dashboard where I can see the video feed, current vehicle density, signal status, and basic analytics for how well traffic is flowing. It should also detect ambulances or other emergency vehicles and give them priority automatically.

Please include login and user accounts, support for switching between a few YOLO model options, and a way to compare model performance. I also want it connected to a SUMO simulation so the signal logic can be tested in a realistic road network, not just on static video. Keep the database simple and local, and make the whole thing runnable on my machine with clear setup steps and some sample data or demo paths if needed.

If anything is unclear, look up the current docs online and make sensible choices.
