Abstract

A study is described which shows that expected conflicts can be estimated with reasonable degree of certainty from a few measurable variables, such as traffic volume and clearance time. This degree of certainty is much larger than what has been attached to estimates of accident expectation. In instances when varialbes that explain expected conflicts are not readily available, sample counts taken over short intervals of time can be used to estimate long-term performance, as in the case of expanded traffic volumes. This ease of measuring and the expanding input data make the approach described here more attractive than the traditional accident-data-based approaches. The details of the study are described.
