abstract="An examination of the concept of probability of danger of collision has been conducted. This approach takes into account various values of the probability of danger of collision and provides a means of introducing a third major parameter into level of service determination. The results indicate that, for the single-lane, car-following situation, the current levels of service are not completely adequate for safety considerations.   <p>Language: en</p>",
