Because of inappropriate operation between oncoming straight and left-turn vehicles of signalized intersections of urban areas in Taiwan the department of traffic ever offered corrigible opinions involve in right of way, center of intersections adjudging hard and indirectly encouraged to accelerate left-turn vehicles. But all still lack quantification analysis. Therefore, this problem is worth studying.This study will aim at safe passage of oncoming straight and left-turn vehicles for at-grade signalized intersections. So, this study will be based on row's theory, theory of traffic conflicts, and take many factors into consideration, such as the width of the intersections, types of the intersections, center of the intersections, the size of the vehicles, the location of the vehicles, the radius of turn, paths of operation, the speed of the vehicles, the types of collisions, the angle of road, and also deduce formulas of coordinate of paths. The main method used in this research is the simulation of different situations. By the method, the analytic model of safe passage of oncoming straight and left-turn vehicles for at-grade signalized intersections will be established, and this study will also subsume critical speed of conflict and expected number of times of safe passage. Finally involved rules of safe passage will be proffered.

Direct left turn from driveways is considered as a contributor to accident and delay in at-grade intersections. Safety benefits of prohibiting direct left turn from driveways have been identified in many studies. Several engineering alternatives have been developed to accommodate prohibited driveway left turns. These alternatives are (1) right-turn followed by U-turn at the down stream intersection;(2) right-turn followed by median U-turn before the intersection;(3) right-turn followed by median U-turn after the intersection;(4) upstream Jug Handle, and (5) downstream Jug Handle.
