摘要

The purpose of this paper is to address two specific questions in the decision-making process for signal coordination: 1) how to interconnect adjacent intersections safely and efficiently and 2) whether dichotomous judgments are sufficient for determining coordination of adjacent intersections. A car-following model was used to calculate the block-length necessary for safety, while May's continuum model and mathematical analysis were used for efficiency. An interval between two values was determined, under which the pattern of performance curve is flat and the performance difference between coordinated and non-coordinated intersections is the most significant in the neighborhood. For adjacent intersections that must be coordinated dichotomy judgments proposed in the literature may not be reliable. The findings of this study may lead to a better understanding of the decision-making process for signal coordination.
