This page contains information about a proposed technology by the authors, which consists of a device that sits inside of a vehicle and constantly monitors car's information. It can determine speed, g-force, and location. Using these data, the device can detect a car crash (or pothole on the road). The data collected from the car is forwarded to a server for more in-depth analytics. If there is an accident, the server promptly contacts the emergency services and contacts with the location of the crash. The pothole information is used for analytics of road conditions for smart city operators.
