Automatic Traffic Density Control System with Wireless Speed Limit Notification

Today, technology had made life easy by providing an alternate smart solution to every problem in society; but when it comes to managing the increasing volume of traffic at a busy junction, the technology implementation is still lagging. Hence a technology-based solution is required to automatically control the traffic signal based on the density of the traffic on a specific lane. It is achieved by sensing the traffic in a particular lane by the ultrasonic sensor and according to the volume of traffic, the green time signal/clearing signal is increased or decreased with the respective red time signal. The proposed system also consists of an automatic SMS alert triggering system to traffic authority when the volume of traffic in a particular lane is increasing even after two consecutive clearing signals. The smart pole is installed with LCD to display the alert message and it contains emergency alert buttons which are used to alert police, traffic, ambulance, fire authorities if any problem occurred in a particular lane. Wireless speed limit notifier is installed in desired lanes which notifies the driver about the speed limit of a zone via wireless technology.
