Speed of reaction of the driver and time of complexes of reactions

One more very important characteristic of reactions and complexes of reactions is their speed. On an estimation, for example, distances to the pedestrian who has appeared on turning movement or the car the certain time is required. The time on separate manipulations with control linkages, on brake pedal pressure etc. also is required. The less this time, the is more speed of reaction of the driver.

The time of complexes of reactions develops of a time of components making it. So, for example, in case of danger emersion at car movement on road to some volume of traffic, the time from the moment of emersion of danger and till the moment of the termination of movement of the brake pedal will develop of a time of components the given complex of separate reactions, such as detection, discrimination, an identification of dangerous installation, an estimation of distance to it, an estimation of a direction and speed of its movement, i.e. The time from the moment of emersion of danger and till the moment of the termination of movement of the brake pedal will develop of a time of components the given complex of separate reactions, such as detection, discrimination, an identification of dangerous installation, an estimation of distance to it, an estimation of a direction and speed of its movement, decision making, carrying over of a foot from the shift pedal the butterfly governor on the brake pedal, pressure of the brake pedal before the termination of its movement. If some components of difficult reactions are carried out simultaneously the time of the general reaction is devided out.

Regimens of movement of installations

If a time of carrying over of a foot and pressure of a pedal more or less constantly, a time on reception and information machining (an estimation of excisions, speeds etc.) there is a magnitude a variable and directly depends on volume and character of the information. The information volume, in turn, depends on extent of volume of traffic on this or that road. The more volume of traffic, the a larger amount of information should be worked overtime to the driver in unit of time, that the time of its complex reactions (inhibition, turning movement) with other things being equal will be big. Character of the information is defined by specificity of parametres of installations of the environment of movement which influences process of machining of the information. This specificity is made, for example, by high-speed regimens of movement of installations.

Besides, if the driver owns the minimum methods of machining of the information on Wednesday of movement and thereof, for example, sweepingly to discriminate and recognise installations, to define remoteness and speed of their movement the time of its separate reactions and complexes of reactions will be less.

The important property of reactions is also variability or stability of their basic characteristics: correctness, speed, accuracy. The spread of parametres on these properties, the more stably reactions and less their variability less.
