Abstract
Arrangement of stop line at intersections of urban roads is one of the most important factors which influences the traffic safety and order of intersection. This paper, grounded on summarizing the design methods for current stop line at intersection, has established constraint model for right-turn and left-turn vehicles at stop line of intersection, established included angle between position of stop line at intersection and the two crossing roads at intersection on account of urban intersections and malformation intersections and on the basis of constraint condition of channelization design at intersections. It has also helped to form the analytic model for parameters related with overall width of both entrance and exit lanes, the width of entrance lane, the turning radius of right-turn and left-turn flow as well as the width of cross walk for result of gaining influence function that each parameter influences on the designed position of stop line as well as for testing the feasibility of such model by examples. The research releases that the designed position of stop line at intersections has a stronger link with the angel of intersections while has weaker sensitivity with other parameters. This paper is aimed at providing scientific way in designing stop line at intersections, increasing greatly the efficiency of intersections and reducing traffic conflicts.
