IoT Traffic Light Display with Emergency Vehicle Management Control System using Wi-Fi

In this research, batteries are used to power the whole system, and if it goes down, you can also charge them. There is also a switch on the system that is used to power it ON/OFF. In this project, the four lanes of traffic are named Lane A, Lane B, Lane C, and Lane D. There is a wireless system that is used to control the four lanes in case you decide not to use the control button on the system. With the help of the ESP32 used in the project, you can connect the system using a WIFI connection to enable you to control the whole system either with your smart phone or your personal computer. The buttons are also labeled A, B, C, and D. Also on the wireless system, it is labeled A, B, C, and D, indicating the four lanes of the project. If there is an emergency in lane D and lane A is the one that is working or giving permission to go, you can use either the control switch from the system or the wireless control system to give lane D permission to go. If the cars in the lane, which is D, have passed, then they will automatically go back to the lane in which they are operating, which is lane A. If all the cars have finished passing in lane A, they will then go to lane B, lane C, and lane D and return to lane A again.
