, Description:System Analysis is done in order to better understand the system’s requirements. Better understanding of the system’s requirements leads to the development of a better system in turn. System Design gives an idea about what is expected by the user from the system. This chapter gives a brief discussion about the detailed study of the proposed system and the different functionalities involved in the features of the system.

To provide early detection of accidents and communicate the information immediately to the emergency responses on time to provide quick assistance for the injured person. When the rider met with an accident and the helmet hits the ground, the vibration sensor which is embedded in the helmet senses the vibration frequency and transfers the value to the raspberry pi module that is interfaced to it. When the vibration threshold frequency exceeds the programmed maximum limit, the raspberry pi board extracts GPS data from the GPS module and the message with all the necessary information is sent quickly to the registered emergency contacts of the rider. This system assures to provide immediate assistance to the victim of the accident. The results give exact locations of the accident.
.EXISTING SYSTEM AND LIMITATIONS
Accident detection and reporting system based on the existing system makes use of the sensors, GSM module, GPS module, Wi-Fi enabled controller and cloud computing infrastructures for the development of the system.

This system builds a smart helmet for accident detection and notification. This system could be implemented only for the purpose of a smart helmet. The helmet is designed to detect an accident and immediately alert the emergency contacts. When an accident occurs and the data exceeds the threshold limit, a text message containing the location of the rider is automatically sent to the family members through the GSM module. The location details are sensed and reported by the GPS module. The related details of the rider are sent to the emergency contacts by utilizing a cloud based service. A Wi-Fi enabled controller is used to connect to a data network for accessing cloud services.
Limitations are,
• Cost of GSM module is not considerable
• The Long term cost by the GSM module is not fully accepted by every user
• Rider do not wear helmet in regions where traffic checking is not done
• There is a tendency of the rider to wear helmet only where they anticipate checking may take place, else they do not wear helmet where no checking is done
• The system could only be implemented for a helmet and it is especially built for the purpose of smart helmet
• Delay in notification reaching the emergency contacts
• In case the contact misses out the accident notification, the system is not designed to recursively send the message until the message has been acknowledged
• The cloud based infrastructures are complicated to be accessed by the system since they have more computational activities

An accident is an unpredicted and unintentional event. Considering the alarming increase in the number of motor bike riders and the number of accidents happening in our country, this system ensures to make the two-wheeler driving safer than before for the rider. The lack of treatment in proper time is the major reason for half of the deaths in road accidents. At the time of accident, the process to intimate and locating the place of the victim is a bit difficult task that is to be discovered. The credentials of the victim are unknown which is tedious during crucial moments for the people at the accidental spot.
The main motive of the project is to design IoT detection and reporting system. The unique feature of the system is to locate the victim and report the accident with the relevant information to ambulances and the rider’s concerned people to provide a quick medical aid to the victim.
A raspberry pi module is used and a unique code is programmed in this module to achieve this functionality. Vibration sensors are interfaced with the raspberry pi module which senses the vibration frequency of the accident. A maximum stress limit of the vibration threshold is programmed in the module.
The GPS (Global Positioning System) Module senses and provides the exact current location of the rider. The GPS module is connected to the raspberry pi and all these are embedded in the helmet. The GPS module will be helpful for the family members and the friends, to track the victim’s location.
Slack application is installed in the rider’s mobile and it is used to switch on and off the system. Slack API is used to sense and trigger a response in our IoT device when the specified threshold level is met. 23
Push bullet is an application that acts as a bridge between your mobile devices and desktop OS and sets the standard for developer updates. This application is installed on all the mobile devices of the registered emergency contacts. Any number of contacts could be stored in the raspberry pi and sent the message. Push bullet provides the way to send notifications from raspberry pi to the mobile phones with a simple scripting. The access tokens of the respective Push bullet and slack applications are programmed in the raspberry pi module.
