A Dynamic Traffic Management System: Construction and Simulation

In this research, a simple representation of a traffic light controller system is designed and constructed. We need three LEDs of red, yellow, and green colors at each intersection. The intersection is divided into four lanes: Lane 1, Lane 2, Lane 3, and Lane 4. All the LEDs are connected to the Arduino NANO’s digital I/O pins (L1 – A5, A4, A3: L2 A0, A1, A2: L3 D10, D11, D12: L4 D0, A6A7) through respective current limiting resistors of 4.7Ω. The IR sensor is interfaced with the Arduino (Rx), which takes the counting, which is sent to the Arduino and displayed via the LCD (8-D8, 9-D9, 4-D4, 5-D5, 6-D6, 7-D7). The Power is regulated from 12v to 5v through Lm7805(25v 220uF) Capacitor IN 4007Diode Thus, VDD = 5v.
