Abstract
The mathematical model of forming a driver’s controlling actions as for the choice of a motion speed on the adjacent road sections was developed. For the development, the methods of the theory of automatic regulation with the application of the transmission functions of a driver and a motor vehicle were used. The model of driving a motor vehicle by the motion speed channel for the drivers with a low level of the motivational perception which was supplemented by another inertia link characterizing the reaction of a driver to the road situation was accepted as a basic one. The value of the maximum entropy of a driver’s perception area was suggested as this characteristic. The periodic change of this parameter is considered on the sections with constant traffic conditions without any other traffic participants. This approach makes it possible to define how to arrange the road sections which follow one another to reduce to minimum the misalignance of a driver’s information load on them. The motion speed of a motor vehicle is obtained as the output value of the model. The margins of a change in the value of the maximum entropy and the limits of the value of speed corresponding to it were established. This makes it possible to simulate a driver’s reaction to a change in the road situation. With the help of the suggested model it is possible to assess the influence of the information content of the traffic environment on the results of a driver’s activity, which finally, makes it possible to develop the measures for regulating the parameters of a road situation and to influence a driver’s working conditions.
Highlights
The basic purpose of the driver’s activity optimization is the creation of comfortable working conditions, when a change in the mental and psychological state of a driver when driving along the road goes smoothly, i. e., the transient process gets as simple as possible
Undesirable transient processes of drivers are the consequence of an abrupt change in the traffic situation while a driver moves from one road section to another
As it is shown in the work [15], the development of driver’s reactions with the periodic change in maximum entropy of a driver’s perception area is possible to be presented in the form of the sequence of square impulses
Summary
The basic purpose of the driver’s activity optimization is the creation of comfortable working conditions, when a change in the mental and psychological state of a driver when driving along the road goes smoothly, i. e., the transient process gets as simple as possible. Undesirable transient processes of drivers are the consequence of an abrupt change in the traffic situation while a driver moves from one road section to another. Regulating the parameters of a road situation, it is possible to influence the conditions of a driver’s work when s/he passes different road sections. The actions of a driver and the character of an automobile motion depend both on the information s/he obtains and the characteristics of a vehicle. An abrupt change in traffic conditions can lead to the emergency and, as a result, to a road accident. The development of a model of a driver’s choice of the motion speed considering the traffic situation is a relevant task in forming the environment of a driver’s working activity
