In India the rate of population is increased day by day but as compare to other countries India is having a poor road transportation system. So due to these the Emergency Vehicles like Ambulance, Fire brigade, VIP Cars, and police vehicles always faced so many problems to reach the destination. If an Ambulance stuck in a traffic then the patient inside it can lose her/his life. Indians now a days gets aware about organs donation the rate of organ donation is also increased. But the main problem in organ transport is that it remains healthy for very short time. So transporting them is a time dependent task. If the Emergency Vehicles do not reach at its destination point in time it causes human health and wealth. So by using a Phenomenon that clearing the traffic signal before an Emergency Vehicle Reaches to the signal using IOT will resolve the problem.
