摘　　要：采用开放边界条件,以元胞自动机模型构建快速公交信号优先仿真评估模型,模拟快速公交信号优先时间(最大绿灯延长时间和最大红灯早断时间)、快速公交信号优先检测器位置以及快速公交产生概率等参数,对含有快速公交专用道十字信号交叉路口交通流的影响.结果表明,通过合理调节快速公交信号优先的最大绿灯延长时间和最大红灯早断时间,可减少交叉口快速公交延误,提高运行效率,降低快速公交信号优先设置对社会车流的影响.A bus rapid transit signal priority model was proposed by means of the cellular automata model under open boundary conditions. The influences of the bus rapid priority time （ the greatest green-light-extended and the greatest red-light-off） , the position of detector and the probability of the traffic flow at intersections with a bus rapid transit lane were simulated. The results indicate that the time delay of bus rapid transit in the intersection is reduced by the rational regulation of bus rapid transit signal priority, such as the greatest green-light-extended and the greatest red-light-off. The proposed method can also reduce the possible inconvenience to vehicles other than buses.
