Development of a Smartphone Application for Safe Car Driving Using Google API and Builtin Sensor In the world where streets brimmed with vehicles are no longer an foreign sight, vehicle accidents come along as one of unwanted consequences. Accidents are due to many reasons, though however the reason is, most of the times it leads to damaged vehicle(s), injuries or even fatality. In this research, we present Car Safe, a smartphone application which can make phone call reception decision, text readout to prevent distraction, driving time alert and send the location of the driver upon the occurrence of a detected crash. While the Google Activity Recognition API only detects driving state approximately 89% of the time, our proposed method yields more than 93% detection.

WisDriver:A WiFi and Smartphone Sensing System for Safely Driving There has been an increasing interest to monitor driverxe2x80x99s behavior, vehicles and driving data aim to identify risky driving maneuvers and prevent accidents. Current monitor methods, however, most data obtained from the vehicle sensors are sent to the control units through buses such as: CAN, MOST, LIN and FlexRay, but cannot recognize the dangerous actions of the drivers accurately. Past proposals for addressing this limitation rely on leveraging more sensors attached to drivers and hence significantly increase the cost and affect the driverxe2x80x99s comfort. This paper introduces the first finegrained and devicefree driverxe2x80x99s behavior monitoring system that is accurate to 15 dangerous driving actions. Unlike past work, which only depends on sensors, our system exploits fusion data combining smartphone and WiFi signals to accurately identify risky driving operations. We present the design and implementation of WisDriver and discuss the evaluation by experiment from the 20drivers field trial. Our evaluation results show that WisDriver can achieve high accuracy (92%) in detecting 15 different dangerous driving behaviors. It will have a great significance for assisting the driver and improving traffic safety.
