A Rescue System of an Advanced Ambulance Using Prioritized Traffic Switching
Human life is affected due to delay in the arrival of ambulance. The ambulance is not able to reach the hospital in the golden hour. It gets stuck in the traffic signals. It would be of great use to the patient if the traffic signals in the path of the ambulance are ON. There must be a system by which the ambulance would reach the accident spot and then hospital as soon as possible to carry out health services . The existing systems are post accident detection systems. It has lack of intelligence. It fails to track the rear-end collision and pre-damage status. It depends on the way of monitoring people to be manual. It requires manual work to save human life which results in time delay and because of that first aid cannot be provided to the patient on time. This leads to loss of human life.
In Pre-collision system, one or more systems may not activate due to sensing and tracking limitations. The actual field performance may be less effective. Limitations in the algorithms and sensors may cause difficulty in real world applications. Moreover, it may use more complex algorithms to determine collision risk. There will be different effectiveness for different algorithms. For the driver’s state, there was only limited information available prior to the collision. There was no effect of pre-collision systems on driver maneuvers such as steering, other than breaking. Further simulation of driver braking deceleration without instrumentation in real-world collision was not feasible beyond constant magnitudes. It did not capture all braking inputs of driver that were possible . These are the disadvantages of existing system. In this paper, we have described a design for automatically controlling the traffic signals so that the ambulance would be able to cross all the traffic junctions without time delay . The server keeps a database for each node for easy access. Hence, each node will have a unique id for addressing the data. The ambulance is guided to the hospital by the server through the shortest route. The sensor installed in the vehicle senses the accident and Global Positioning System (GPS) tracks the location of the accident . Through GSM (Global System for Mobile Communications), it sends the location of the accident to the ambulance section. The buzzer produces sound when accident occurs. The central unit finds the ambulance, nearest to the accident spot and also the shortest path between the location of the accident, ambulance and the nearest hospital. Here, wireless technologies are used for information transferring. The traffic signals on the path of the ambulance are controlled. When the ambulance reaches the traffic junction, the encoder converts the serial data into parallel data when it passes from the transmitter to the receiver. If the signal is red, it comes to green automatically. The decoder in the receiver section converts the parallel data into serial data when it is sent back. This helps the ambulance to cross the traffic junction as soon as possible. The prioritized traffic switching is done priority wise, i.e. if two ambulances are coming at the same time, the ambulance which will arrive first at the traffic junction will be given the priority to cross the traffic junction before the next ambulance arrives . In this way, using wireless technologies, the information is transferred and the traffic signals are controlled so that the ambulance would be able to reach the hospital on time.
Significant work has been done by the help of which a design for automatically controlling the traffic signals has been described. The applications of powerful portable devices for human activities are described . An automated mobile system for road safety services is described. It provides support to emergency service vehicles (EV) for accomplishing the mission faster. It is more reliable. The system must be based on standards, fully automated, flexible, intelligent and low cost. The availability of more pervasive and newer communication networks such as Zig Bee, WiMAX and mesh networks is more reliable. The objective of the system is to fulfill the needs of an error free and efficient emergency system. In case of an accident, it can accurately and quickly find the ambulance and send it to the accident spot without the requirement of manual work. It is made to reduce human errors, wrong data or treatment. The solution to traffic congestion problem and an advanced algorithm have been described to find the shortest path in car navigation system . It is difficult for many drivers to find an efficient route. These systems can perform the task of determining the best path to the destination. The process of finding the shortest route from one point to another is called routing. A new algorithm is proposed in this paper. It is a modified version of dijkstra. These methods can improve used memory and run times because the visited edges and nodes are limited. Traffic congestion is a social problem that occurs because of the increasing number of vehicles. Here, a pheromone model is applied to a traffic signal control to alleviate traffic congestion. It is spread by vehicles across the road. The amount of pheromone correlates to traffic congestion. The factors of traffic signals are controlled by the pheromone to reduce the inactive time in front of it. In the references , the emergency rescue system reliability on highway and intelligent ambulance have been described. To make sure, that the ambulance would arrive at the location of the accident on time and would reach to hospital as soon as possible to provide health services to the patient, the emergency rescue system started. It analyzed its structure on highway in three ways: rescue plan, incident detection and equipment management. The reliability of the system is discussed based on the travel time. Then a mathematical model of the reliability of travel time is established. At last, a model example for the reliability of travel time is showed. The intelligent ambulance is designed for the wounded to maintain the level of self-balancing state. To detect the gravitational vertical stretcher, it works on the principle of gyroscope. It is converted into pulse signals to drive the motor through the microcontroller. To adjust the angle, it is controlled by the motor to the full balance from the ambulance. In , an application on the ambulance routing of the A* algorithm is described. In the case of an accident, comprehensive care and quick response is vital for taking the patient to the nearest hospital if intensive care is needed. In order to ensure, the ambulance reaches the accident site on time and the patient is taken to hospital without time delay, the application of road network and A* algorithm for the development of the ambulance routing system is described in this paper. The methods which are mentioned are used to find the shortest route for the ambulances to reach to the emergency site faster. It is used for the emergency medical services (EMS) ambulances. It is always suitable if the ambulances an arrive at the emergency site faster as the intensive care can be given to the patient as soon as possible and many lives can be saved.
