Automated traffic signal for hassle free movement of ambulance

Each traffic signal is a process which needs to be scheduled at a time to completion, thus following non preemptive scheduling. In static traffic systems each traffic signal is provided with a fixed amount of `green´ time, thus compelling the Emergency Medical vehicle to wait till the corresponding traffic signal gets `green´ and the accumulated vehicles starts to move, thus wasting valuable time. We through the paper like to propose an alternative solution for hassle free movement of ambulance by introducing a Dynamic traffic signal using traffic density measurements, in which the traffic signal flow is modeled as non preemptive scheduling of processes to which the sole resource `Time´ is allocated effectively so as to felicitate hassle free movement of ambulance. The traffic densities are measured using Radio-frequency Identification readers that provide a count of vehicles, which are fitted with Radio-frequency identification tags. The distributed server uses a microcontroller to perform the computations based on the proposed algorithm. Probability of saving lives is staggeringly more during golden hour. Keeping this in mind our project aims at providing ample amount of time for ambulance to not only pass the signal without hindrance but allows for smooth traffic movement in other roads joining a junction.
