Introduction

The time interval between the receptor receiving stimulus and the effector to react is called the reaction time. By measuring the reaction time, the functional level at different aspects of the reflex arc of human nervous system can be understood and evaluated. The faster the body reacts to stimuli, the shorter the reaction time, and the better the flexibility. 

Among the many factors that cause traffic accidents, the physical and mental status of cyclists and drivers is particularly important, especially the speed of their reaction to traffic lights and car horns, often determines the occurrence and severity of traffic accidents. Therefore, it is of great significance to study the reaction speed of cyclists and car drivers in different physiological and psychological conditions for reducing the occurrence of traffic accidents and ensuring the safety of their own lives and others. 

This apparatus is designed with reasonable and practical configuration. Its experiment content is rich, that can simulate the driver's actions on handbrake or footbrake respectively, and can study human reaction time from both aspects of vision and auditory. At the same time, this apparatus can be used to analyze the reaction characteristics of drunken driving behavior. It can still be used to test the reaction time of people of different age ranges. Please click Experiment Contents to find more information about this apparatus.

Using this apparatus, students can perform the following experiments:

1. Study the braking reaction time of cyclist or car driver when the signal light is changed. 

2. Study the braking reaction time of cyclist when hearing the sound of a car horn.
