This document proposes a smart traffic control system using programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA). The system would use weight sensors to divert traffic into lanes based on vehicle type (e.g. buses, trucks, cars). Traffic density would be monitored using vehicle counters, and traffic lights would change based on congestion levels. A SCADA interface would allow monitoring of traffic status and diversions. The system aims to reduce congestion and accidents by separating vehicle types into different lanes based on weight.
