Simulation of Driver Behaviour as a Function of Driver Error and Driver Daydream Factor

Abstract: A driver-vehicle interaction model consisting of a closed loop system, developed recently, has been used to simulate the behaviour of drivers having different values of driver error and driver day dream factors. Concept of Risk Time, Driver Error and Driver Daydream Factors is presented and used to evaluate the vehicle-driver model. A process cycle of a driver-vehicle model is set up based on man-machine system theory. Crash conditions between two vehicles is presented, which can be used to design the intelligent control scheme for the highway system. When the risk time is large the normal driver is less attentive and the cycle time, defined in the driver model, becomes large. However, some drivers can have a cycle time comparable to the risk time. The value of the driver daydream factor, defined in the paper, becomes large for such drivers. The muscle response of such a driver is usually slower, giving rise to large values of the driver error in the driver model. The results for simulations of vehicle following another vehicle while changing the speed and driving under varying visibility conditions are presented. The computational results obtained have only logical and qualitative support; an exact quantitative comparison is not immediately possible.
