本文提出了一种新的单车道车辆跟驰模型，该模型综合考虑了车辆的胆怯行为和攻击行为。得到了包含胆怯行为和攻击行为项的线性稳定性条件。数值仿真表明，新的跟驰模型能够在考虑车辆胆怯行为和攻击行为的情况下，估计出合理的车辆运动延迟时间和阻塞密度下的运动波速。研究结果还表明，攻击性行为能改善交通流，而胆怯行为则会降低交通稳定性，即攻击性行为优于胆怯行为，因为攻击性驾驶员对前车速度的变化能做出快速反应。速度快照也表明，新模型可以逼近宽运动堵塞。
In this paper, a new car-following model is proposed with the consideration of the incorporating timid and aggressive behaviors on single lane. The linear stability condition with the incorporating timid and aggressive behaviors term is obtained. Numerical simulation indicates that the new car-following model can estimate proper delay time of car motion and kinematic wave speed at jam density by considering the incorporating the timid and aggressive behaviors. The results also show that the aggressive behavior can improve traffic flow while the timid behavior deteriorates traffic stability, which means that the aggressive behavior is better than timid behavior since the aggressive driver makes rapid response to the variation of the velocity of the leading car. Snapshot of the velocities also shows that the new model can approach approximation to a wide moving jam.
