Road accidents are considered as one of the primary cause for death in the country. For this, advanced wireless technologies and intelligent systems are arising with the introduction of technologies. This is known as e-call device that helps in the development of various safety and efficient services for the purpose of road transportation.
E-call device helps in the transmission of emergency calls that are considered as appropriate to provide public service along with data related to vehicle. These types of technologies can work both with and without the intervention of human being. With the addition of the data link, there is always a voice connection between rescue center and the vehicle.
When there is a road accident, this e-call device communicates about the seriousness and provides accurate location of the vehicle that is involved in an accident. For the removal of causalities, by minimizing the response time, there are several companies that is promoting this emergency device, whenever any accident occurs.
The device is a the perfect combination of In Vehicle system (IVS), GSM Cell Phone and GPS location capability along with a corresponding infrastructure of Public Safety Answering Points (PASAPs) that is connected to the sensors of the cars or vehicle.
This architectural technology is provided to various numbers of service providers and car makers. It can trigger an emergency call which can detect the accident from the sensors fitted inside the car or by the manual interaction of the users, which is known as SOS button.The device also faces some of the obstacles including standardization of various protocols of communication and human language issues.
Some prototypes are tested with GPRS and in-band signaling over cellular networks. During the time of accident, other details can be provided for the device if any person is capable of answering and speaking questions. It includes short range communications. This type of service is considered as software that can be installed in a special kind of box through wired or wireless link.
There are several other special services that are mostly used by two-wheeled vehicles and second-hand cars. But this service does not contain any in-build systems. This e- technology is highly efficiency and effective which will play a significant role in future emergency service system.
