Abstract: A green wave on a road with a series of coupled signalized intersections enables a driver to pass each traffic light at green light. The Green wave systems are most suitable to provide clearance to emergency vehicles during rush hours many systems are used to implement the green wave systems. We have developed a cost effective system using Radio frequency identification (RFID) Technology Global system for mobile communication (GSM) modules and latest high speed microcontrollers to achieve the desired results. The primary objective is to identify the emergency vehicle and track its location so that we can provide a green wave to the emergency vehicle. To alleviate congestion public transport can be improved or the Infrastructure can be expanded. In urban areas, the latter is often infeasible due to residential Areas adjacent to the existing roads.
