This paper investigates a benefit from a decrease in an accident rate which is one of benefits when driver uses an expressway. As the occurrence of accidents is a probablistic phenomenon, it is difficult to explain the benefit of risk-decreasing behavior by an usual consumer theory. Then an expected utility theory will be used to analyse a consumer behavior under uncertainty.It is a behavior as a risk-averter that a driver may choose an expressway which is a tollroad instead of a street which is not charged in order to reduce the accident rate. Therefore an insurance theory will be adopted to examine the behavior of a driver as a risk-averter. By the way, there are three kinds of insurance behavior accoding to I. EHRLICH AND G. BECKER; they are market insurance, self insurance, and self protection. In this paper, an idea of self protection will be used to explain the drivers risk-averting behavior because the driver will increase the frequency of using an expressway in order to reduce the probability of anaccidents.Consequently, the result of appling the self protection theory to explain the drivers behavior is plausible; for example, the increase of a probability of an accident on a street make the driver to use an expressway more frequently, or the rise of a toll of an expressway reduces the frequency of using it. From this result, it may be benefieial to apply an insurance theory to road problems.
