2.3 Need Analysis: In-order to meet the new system requirements, the following are various components specified for our proposed system
• Impact Sensor
Impact sensors should be deployed on front body of the car, as that is the first part which faces the accident. This device registers the action at first. This sensor measures the speed of the wheel, pressure applied on break, increased pressure to detect whether it is an accident or not. It sends signals to the immediate device which confirms the accident and sends emergency note. The transfer of signals should happen within milliseconds of collision.
• GPS Sensor
GPS stands for Global Positioning System. GPS Sensor serves like a receiver provided with an antenna. This component uses satellite-based

The microcontroller should erase the message as soon as it is sent to the emergency contact. This will help in preserving the memory of the component, rather than inducing additional memory peripheral.
• Message content
The content of the message consists of crash site location details, time. Site details should contain geographical location co-ordinates, rather than alphabetical address details (the one we see on Google Maps). This is because, co-ordinates will have latitude and longitudinal numerical, which are known for their accuracy in showing the location of a position at any point on the Earth.
• Wireless Transmitter/Receiver
This module helps in delivering the message to the emergency contacts. Transmission of a message from a remote location is a challenging task for any system. Inducing a transmitter with multiple antenna would be more helpful, as it works with more strength. This device takes the message content from microcontroller and transmits it to the other end.
• Power source
The whole proposed system should be battery-powered. When a crash occurs, there is a chance that the vehicle may loose power source all over the body. To overcome this flaw, rechargeable battery should be the only source of power supply to the system.

SYSTEM FEASIBILITY ANALYSIS
2.1. Operational Feasibility
2.1.1. Internal Evaluation:
To identify operational feasibility of implementing new enhancements in our product, we are borrowing the PIECES framework, described as follows:
a) Performance: High level of safety, Trustworthy Device Components, Comfortable Riding Experience.
b) Information: Compatibility with existing cars, User Manual with Instructions, In-detailed Technical specifications.
c) Economy: Cost-effective device and spare parts.
d) Control: Effortless control of components by user.
e) Efficiency: Manufacturing devices with maximum efficiency, Implementation of latest technology in making of devices.
f) Services: Accessible customer service process, Promoting the usage of the product.
After evaluating this framework in Brainstorming session, we concluded to rate all these under a 5-point scale measurement. The below tabular form shows the results obtained after our evaluation. According to the scale, 0 represents Inadequate, 5 represents Highest point. Weighted Decision Matrix for Internal Operational Feasibility Operational
