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.
鉴於台湾都市地区路口对向直行左转车辆常遭受对向车辆不当驾驶行为干扰,因而道路交通主管机关曾针对路口对向直行左转相关道路交通法规可能产生之对向直行左转路权判断不易、路口中心处不易区分、间接鼓励路口转弯车加速左转等问题提出检讨之修正意见,唯整体考量仍缺少〝量化〞分析,系一值得研究之课题,因此,本研究将针对号志化平面路口对向直行左转车辆安全通行问题於法规层面上之特殊性,以交通冲突理论、路权理论为基础,并考量路口宽度、路口型式、路口中心处、车辆尺寸、转弯半径、运行轨迹、行驶速率、行车位置、最终碰撞型态、道路交角等因素,先行推导车辆行驶轨迹座标公式,再利用情境模拟分析法,进行号志化平面路口对向直行左转车辆安全通行分析,分析过程中则纳入冲突临界速率与安全通行期望次数理念,并根据路口对向左转车辆安全通行轨迹、速率集中分布范围之分析结果及相关理论,研拟号志化路口对向左转车辆安全通行轨迹、速率,及对向直行左转车辆路权判断原则,以供驾驶者路口直行左转安全通行之参考。
