Motorsafe: An Android Application for Motorcyclists Using Decision Tree Algorithm In Vietnam, prohibitions on using the telephone while driving vehicles have effected in a long time. However, that is relatively common and dangerous for traffic participants in reality. Along with the continuous growing of smartphones, using phone while driving is becoming a bad habit and one of the major causes of crashes and accidents of traffic in Vietnam. MotorSafe is a novel application that has been practically implemented as a solution for this problem. From the obtained data of the accelerometer sensor on the smartphone, a proposed decision tree algorithm enables device to recognize the useru0027sxc2xa0 status on driving a vehicle. Some necessary tasks are provided that will help drivers focus on driving instead of unnecessary behaviors.

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.
