Description

The purpose of this research is to evaluate the degree of risk compensation for the following drivers' behaviour with short headways between cars in case of high speeds. To do this, two experiments are done: The first one is to measure the response time of the following drivers. The second experiment is done by using eye-mark camera to measure the eye movement. The results showed that when the headway is short, the response of the driver is faster comparing with the long headway. Also, the percentage of eye-fixation in case of the short headway for the visual angle more than 5° around the break lights is small in comparison with the long headway. Therefore, it is concluded that inspite of there is risk compensation behaviour in the short headway, but the degree of risky is very high.
