Density Based Auto traffic Signal Control with Android Based Remote Override
The project is designed to develop a density based dynamic traffic signal system having remote override facilities. During normal time the signal timing changes automatically on sensing the traffic density at the junction but in the event of any emergency vehicle like ambulance, fire brigade etc requiring priority are built in with Android application device remote control to override the set timing by providing instantaneous green signal in the desired direction while blocking the other lanes by red signal for some time.
The sensors used in this project are IR and photodiodes are in line of sight configuration across the loads to detect the density at the traffic signal. The density of the vehicles is measured in three zones i.e., low, medium, high based on which timings are allotted accordingly. The override feature is activated by an on board Bluetooth device from the Android application device operated from the emergency vehicle. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. |
