The invention discloses a test evaluation method for bus signal priority control. Firstly, a traffic intersection of a city is selected as a test site, and a test scene oriented to bus signal priority control is established. And secondly, in order to comprehensively, accurately and reliably obtain bus motion state parameters in the bus signal priority control induction process, the position, speed and acceleration information of the bus is accurately estimated by adopting an extended Kalman filtering algorithm in combination with a uniformly accelerated motion model. And finally, on the basis of accurate recursion of the motion state parameters of the bus, a plurality of quantitative indexes such as the induction distance, the driving smoothness in the induction process and the urgent acceleration/urgent deceleration behavior in the induction process are provided, test evaluation is carried out on bus signal priority control from multiple angles, and accurate, reliable and scientific quantitative evaluation is realized.

    本发明公开了一种面向公交信号优先控制的测试评价方法。首先,选取城市的交通路口作为试验场地,建立面向公交信号优先控制的测试场景。其次,为了全面、精确、可靠地获取公交信号优先控制诱导过程中的公交车运动状态参数,结合匀加速运动模型,采用扩展卡尔曼滤波算法对公交车的位置、速度、加速度信息进行准确估计。最后,在公交车运动状态参数准确递推的基础上,提出了诱导距离、诱导过程的驾驶平顺性、诱导过程的急加速/急减速行为等多个量化指标,从多个角度对公交信号优先控制开展测试评价,实现了精确、可靠、科学的定量测评。
