Increasing the use of vehicles on the roads can now pose several challenges in providing emergency assistance during an accident that could seriously threaten human lives. During the accident, many people may lose their lives due to delayed medical services or the ambulance may be stuck in traffic jams, and victims of accidents may die while waiting for first aid kits and medical help. Hence deaths from road accidents are very common. There are many accident prevention systems that prevent accidents to some extent, but they have no type of facility to communicate with or contact relatives ,friends in the event of an accident. An automated mechanism of accident detection that initiates itself and alerts the registered contacts if an accident occurs, and also provides the victim’s live location. This program will determine whether there was an incident or not. An android application is developed which detects and sends alerts to the emergency contacts concerned. External pressure change, sudden jerk on the device, will be observed using pressure sensor, accelerometer, and GPS respectively.

TRANSPORTATION is one of the most important day-to-day needs and has made our work much easier. In today’s world the number of vehicles also increases as the population increases day by day. This leads to more traffic jams which ultimately lead to accidents. The transportations which facilitate our lives can cause many human lives to suffer disasters and even kill us through accidents. No one wants to counter an incident, but it is an unforeseen event or a situation that is unplanned. Drivers can’t avoid accidents but we can help reduce the amount of death that occurs during an accident with the use of the technology and current developments. Due to the increased number of transportation, it has given rise to more number of road accidents. [8] Many road accidents are increasing day by day, and have posed a major challenge to public health in the community. Every day we come up with the news of accidents only in the newspaper. Today’s deaths among the population are prominent due to road accidents. Road traffic injuries are the leading cause of death among young people between the ages of 15-29 and cost countries 1-3 per cent of gross domestic product. If no action is taken, it is estimated that road traffic accidents will cause the deaths of about 1.9 million people annually by 2020. There are so many reasons for road accidents, such as the growing number of vehicles, improper road construction and maintenance, and many more. Often the younger generation loses their lives in road accidents due to drink driving, reckless driving and many other reasons that are a huge loss to our country. In many cases of accidents, the victims suffer serious injuries where time plays a very important role in saving lives. If the incidents have happened in a remote area where there are no cars or people around to report an incident, this system would also be a blessing to the victims of Hit-n-Run collisions because there is no one around to witness and call for help at the moment. To address this, we need an intervention as soon as an incident happens and the least amount of time is lost, because any second of medical assistance waiting can be fatal. There are several applications that are designed for this purpose but all of them are hardware based. This system ‘s approach is special, and is focused on mobile apps. It uses all the hardware that is mounted on a mobile app including accelerometer , gyroscope and many more that can detect an accident on itself.


  1. Smartphones

    Smartphones are a class of mobile phones and mobile computing devices for multipurpose use. It is a cell phone that lets you do more than just make phone calls and send text messages. It can browse the internet and run computer-like software programmes. Smartphones use a touch-screen to communicate with users. There are numbers of mobile applications that all run on the phone, including sports, personal use and business-use programs

  2. Android

    Google-based Android, a mobile operating system. It is a Linux based operating system and software kit for mobile devices such as tablet computers and smartphones. Google develops it, and later the OHA (Open Handset Alliance). Many other languages may be used to write the android code including Java.

  3. Android Studio

    Android studio is the primary android integrated development environment that offers an android developer’s all the required tools to create an android application. Java and XML are the only languages needed to build Android Studio applications

  4. Accelerometer

    An accelerometer is an electromechanical system that calculates acceleration properly. Proper acceleration is not the same as coordinate acceleration, being the acceleration of a body in its own instantaneous rest frame, being the acceleration in a fixed coordinate system. In cell phones, it is used to measure the phone’s orientation for calculating the forces of acceleration.

  5. Gyroscope

    A gyroscope, a device used to measure or maintain orientation and angular velocity, and used to detect the phone’s orientation, adds dimension to the information the accelerometer provides by tracking rotation or twist. It is a rotating wheel or disk in which the rotation axis is free to assume any orientation of its own accord.

  6. GPS

    The Global Positioning System is a satellite-based navigation system made up of at least 30 satellites orbiting the Earth at an altitude of 20000 km. It works in all weather conditions, anywhere in the world, 24 hours a day, with no subscription fees or setup charges.


[8]In the event of an accident, a sudden jerk develops which can cause a phone to fly off or be stationary at all. The phone’s accelerometer can detect that sudden jerk. If the jerk is detected by the accelerometer the gyroscope goes into action to test whether or not the accident has occurred. Gyroscope checks for changing the phone’s orientation if the accident occurs, the phone bursts or falls with the victim, which changes their orientation. But sometimes false alarm can be generated so that the mechanism to avoid this is applied, a condition has been implemented where the user will have 10-15 seconds to press the ‘I’m all right’ button on the application and disable the application from sending the alert message to the emergency contact numbers registered on the phone. If the reset button is not pressed, and all other conditions are met, then the accident is confirmed. The location is identified then using the phone’s GPS system. Once the Location is obtained the added pre-generated SMS with the current location is then sent for emergency support to the registered contact. In this work we use android smartphone to detect accidents and report it to the nearest emergency responders available with the exact location of victims in emergency. The system will inform respondents on an emergency response side about the incidents that occur near them and provide them with real-time tracking of emergency victims on a Google map. It would allow first responders to keep track of the location of the victim and evacuate them as soon as possible. If the smartphone gets some sudden jerk or tilt by any wide angle, the device will assume that the gyro sensor has caused an accident. The machine is expected to wait 10 seconds. If the patient hits the reset button within 10 seconds the machine will assume that there has been no incident and it resets back to normal service. Even if you do not push the reset button it will be treated as a serious accident. The vibration and gyroscope sensors then detect the incident, and a message is immediately sent to the emergency contact number using the GSM module along with the location detected by the GPS module.



[8]The use of smartphones to detect road haulage incidents is not a new issue. There are several device algorithms that use both accelerometer and GPS to identify incidents with vehicles using smartphones. As this has already been achieved, we agreed to build a complete framework that is more robust and practical than the current ones. [1]The vibration and gyroscope sensors detect the accident in this paper and a message is sent immediately to the emergency contact numbers using the GSM module along with the location found by the GPS app. If there is any head-on collision the vehicle produces the vibrations. These are detected if the vibrations exceed the threshold value. The system’s central processing unit will sense that there has been an accident. [4]They have determined a two-way identification step in this paper to check whether or not the accident happened. The first is the accelerometer by which it can detect any sudden tilting of the vehicle in the event of an accident. The heartbeat sensor will then sense the victim’s heartbeat rate and determine the seriousness of the accident based on changes in heartbeat, a message will be sent to the control room along with the location of the accident and emergency contacts. The android application will also send a text message along with the location of the accident to the nearest medical hospital with the help of GPS which will help save crucial time. [2]The framework consists, in this document, of an accident detection and warning system along with an android program. Every time a hardware device is mounted onto the motorcycle. It consists of an Arduino, an accelerometer, two sensors of vibration, a motor, a GPS module, and a GSM module; The decision on whether an accident has occurred or not will be made based on an algorithm. The system will send an alert message to the nearest medical center in case of an accident, informing that an accident has occurred along with the vehicle’s message and current location. For the purpose of Anti-Theft, the user should receive an warning message once the vehicle’s engine starts and in case of theft he may start or stop the engine on his orders.


From the point of view of the emergency victim, emergency victims are not usually able to call an ambulance on their own during fatal accidents, in such situations the designed application system will automatically detect the accident and send an emergency notice to the nearest registered emergency contact responder available, hopefully to save the life of the victim. It is much quicker and simpler to send an emergency warning, because all the necessary functionalities reside together. The program also offers options for sending requests to the appropriate emergency services in case of certain emergencies, such as calling an ambulance, contacting hospitals and physicians. From the point of view of emergency responders, the application will show the location of the emergency that occurs near them, this will help to reduce response time, so that victims can be tracked in real time and rescued as soon as possible, leading to a more efficient use of emergency services resources.


[8]In this research, we developed an accident detector as a smartphone application and communication system using an accelerometer sensor to detect an accident, generating an emergency alert message and sending it to the registered emergency contact number along with the accident location coordinates. The program will provide medical help in time for an accident victim with the real-time location monitoring for both the victim and the respondent, which will improve the victim’s survival rate.
