PDF File Detect Car Accidents Using Smartphones and Wireless Mobile Sensor. Using Smartphones and Wireless Mobile Sensor Networks to Detect Car Accidents and Provide Situational Awareness to Emergency Responders. Summary. Accident detection systems help reduce fatalities stemmin g from car accidents by de- creasing the response time of emergency responders. Wirele ss mobile sensor networks coupled with smartphones and their onboard sensors (such as GPS receiver s and accelerometers) are promising platforms for constructing such systems. This paper provid es three contributions to the study of using smartphone-based wireless mobile sensor networks as accident detection systems. First, we describe solutions to key issues associated with detecting traffic accidents, such as preventing false positives by utilizing mobile context information and poll ing onboard sensors to detect large accelerations.
