摘要： 为了描述真实交通环境中车辆交错跟驰的现象,在全速度差模型的基础上引入了视觉角和侧向偏移角的概念,采用侧向偏移角变化率作为衡量车辆横向运动的关键参数并建立了考虑侧向偏移的车辆跟驰模型。通过线性稳定性分析得到了新模型的稳定性条件。理论分析和数值仿真结果表明:改进模型能够有效地描述车辆交错跟驰行为对交通流稳定性的影响,侧向偏移会减少交通流稳定区间,更容易使稳定车流变成时走时停交通流。

Abstract: In order to describe staggered car following behavior in real traffic environment, a novel car following model was proposed based on Full Velocity Difference (FVD) model by incorporating the visual angle. The rate of change of the lateral separation angle is taken as a key parameter to describe the effect of lateral separation distance. The stability condition of the model was obtained using the linear stability theory. Then the characteristic of the model was investigated by theoretical analysis and numerical simulation. Results show that the lateral separation leads the stability of the proposed model smaller and the easy formation of stop and go traffic. The above findings have great practical significance to improve the stability of traffic flow and analyze car-following characteristics considering the lateral movement.

Key words: engineering of communications and transportation system, car following model, visual angle, lateral separation
