本文提出了一种新的车辆跟随理论，该理论可以再现多相车辆交通流的两个突出特征——容量下降和交通滞后。这是通过引入一个变量来实现的，即间隙时间，它取决于车辆间隙距离和交通阶段。通过指定不同的间隙时间函数形式，不仅可以得到全新的理论，而且可以得到一些众所周知的老的跟车理论，本文通过理论分析和数值模拟来证明这一点。
We present in this paper a new car-following theory that can reproduce both the so-called capacity drop and traffic hysteresis, two prominent features of multiphase vehicular traffic flow. This is achieved through the introduction of a single variable, gap-time, that depends on both vehicle gap-distance and traffic phase. By specifying different functional forms of gap-time, one can obtain not only brand new theories but also some of the well-known old car-following theories, which is demonstrated in this paper through both theoretical analysis and numerical simulation.
