Driving Behavior and Traffic Safety: An Acceleration-Based Safety Evaluation Procedure for Smartphones

摘要: Traffic safety and energy efficiency of vehicles are strictly related to driver’s behavior. The scientific literature has investigated on some specific dynamic parameters that, among the others, can be used as a measure unsafe or aggressive driving style such longitudinal lateral acceleration vehicle. Moreover, use modern mobile devices (smartphones tablets), their internal sensors (GPS receivers, three-axes accelerometers), allows road users receive real time information feedback that useful increase awareness drivers promote safety. This paper focuses development prototype application evaluate grade keeping by measuring accelerations (longitudinal lateral) warning for when it convenient correct style. aggressiveness is evaluated plotting vehicle’s g-g diagram specially studied designed, where horizontal displayed inside areas “Good Driving Style”. Several experimental tests were carried out with different cars in order estimate system accuracy usability application. work part wider research project M2M, Mobile Mobility: Information communication technology systems traffic (PON National Operational Program Research Competitiveness 2007-2013) which based sensor computing giving real-time reduce risks make transportation more safe comfortable.
