GAP ACCEPTANCE AND WAIT TIME AT UNSIGNALIZED INTERSECTIONS

The primary purpose of this study is to determine if driver gap acceptance behavior changes as the time spent waiting for an acceptable gap increases. We propose three hypotheses dealing with this issue and present a sample of results pertaining to the first two hypotheses. Special attention is given to the methods used to collect the data used in the study and to define the key events involved in driver behavior at unsignalized intersections.
