Active Safety Systems Development and Driver behavior Modeling: A Literature Survey

摘要

It has been pointed that most of the accidents on the roads are caused by driver faults, inattention and low performance. Increasing stress levels in drivers, along with their ability to multi task with infotainment systems cause the drivers to deviate their attention from the primary task of driving. Hence much emphasis is being given to occupant safety. This probe study gives a system structure depending on multi-channel signal processing for three modules: Driver Identification, Route Recognition and Distraction Detection. Driver inattention is assessed and an overall system which acquires, analyses and warns the driver in real-time while the driver is driving the car is presented showing that an optimal human-machine cooperative system can be designed to achieve improved overall safety. The novelty lies in personalizing the route recognition and distraction detection systems according to particular driver with the help of driver identification system. The driver ID system also uses multiple modalities to verify the identity of the driver; therefore it can be applied to future smart cars working as car-keys. All the modules are tested using a separate data batch from the training sets using eight drivers' multi-channel driving signals, video and audio. The system was able to identify the driver with 100% accuracy using speech signals of length 30 sec or more and a frontal face image. After identifying the driver, the maneuver/route recognition was achieved with 100% accuracy and the distraction detection had 72% accuracy in worst case. In overall, system is able to identify the driver, recognize the maneuver being performed at a particular time and able to detect driver distraction with reasonable accuracy.
