18. REAL TIME DENSITY BASED INTELLIGENT TRAFFIC CONTROL SYSTEM

The paper is aimed at designing a density based dynamic traffic signal system where the timing of sign will change naturally on detecting the traffic thickness at any intersection. Gridlock is a serious issue in many urban areas across the world and in this way the time has come to move more manual mode or fixed clock mode to a mechanized framework with dynamic capacities. The point of our venture is to foster a Density Based Traffic Signal System utilizing PIC microcontroller. In this framework, we will utilize IR sensors to gauge the traffic thickness. We need to mount three IR sensors for every stre et; the distance between these sensors will rely upon nature of traffic on a specific intersection. These sensors will detect the traffic on that specific street. Every one of these sensors are interfaced to the PIC microcontroller. In light of these sensors,controller detects the traffic and dynamically set up the time delay of signals. One more application adds here by using RFID Card reader to detect the emergency vehicle and give the green path signal to pass safely.
