Abstract: This research suggests a new approach to man-machine interface, that is based on the characteristics of an imaginary individual|s driving behaviour and the easily detected car control figures. The adaptive resonance theory (ART) network is combined with the computer-aided learning of the Fuzzy Neural Network to obtain the different appropriate safe car-following headway between cars that are running under different speeds. The framework of this system is divided into two major parts. The first part uses the ART network, which uses the differences between the required least horizontal braking distance of a car, and the distance between the car and the obstacle standing on the end of the lane at the moment the driver applied the brakes, during a test where the car is running on a straight lane at accelerated speed. An off-line Self-organizing cluster discovering is conducted. The clusters of the above-mentioned two distances obtained through the ART network are used to determine the levels of the risk-taking factors of the drivers. Then the output of this ART network (i.e. risk-taking factor level), car speed and free travel of brake pedal are used as the fuzzy neural network (FNN) input; the appropriate car-following headway serves as the FNN output. Through the learning capability of artificial neural network, the complex membership functions between the inputs and the output can be efficiently established. Finally, the appropriate car-following headway predicted by the FNN are compared with the actual field data to prove the accuracy of the system in predicting the different safe car-following headway, given different driver and different car characteristics driven at different speeds. The completion of this system provides a feasible course for the development of a neural network in an individually-oriented man-machine interface system.
