COGNITION aims to develop a software solution for early recognition of abnormal and inattentive driving in order to prevent road accidents and increase traffic safety. More specifically, the aim of this project is to develop an application which gathers data from mobile phone sensors, processes it and warns the driver about potentially dangerous situations. It is intended that the project culminates in the provision of a valuable service in the area of traffic safety. Moreover, if driving behavior such as inattention and drunk driving can be detected and prevented in a timely manner, most road traffic accidents can be prevented. In addition, vehicle dynamics and driving behavior can also be applied to crowd detection to help traffic planners analyze traffic conditions and make correct decisions.
