Yellow Signal Driver Crossing Behavior

This paper studies the frequencies of vehicle entrance times to non-urban intersections after the yellow onset. Data obtained from loop detectors connected to digital enforcement cameras during 2 years included nearly 5 million yellow and red entrances to 37 intersections. The frequencies of crossing times relative to yellow onset are explored. In a previous publication the authors showed that the analysis is valid as long as the frequencies of entrances at the beginning of the yellow phase (for example, during the first second) are constant, and therefore 8 intersections were excluded. For the remaining 29 intersections the authors examined the fit of both standard (exponential) logistic regression and four parameter logistic regression to describe the frequencies of entrance times after the yellow onset over time from yellow onset. The results show a clear advantage for the former. The models show that the time when the frequency of crossing reduces to half ranges from1.7 to 2.3 sec after yellow onset. The reduction of the relative frequency from 0.9 to 0.1 ranged from 1.9 to 2.9 sec. In addition to the main findings from the previous publication the authors present here a discussion of taxonomy and several new analyses.
