The Analysis of Stop Line Arrangement for At-grade Intersection

The position of stop line has great effect on the traffic operation in intersection. For the geometry design of intersection, there are no available analytical models or procedures that can be used to position the stop line. In this paper, the existing considerations for stop line design in at-grade intersection are discussed and the variables that impact the arrangement of the stop line are figured out. After analyzing the targets and the restrictions of the stop line arrangement, the models for determining and optimizing the position of stop line are established and the relationship between these variables discussed. A practical application in an intersection in Xiamen is proposed to verification the procedures and models.
