An ACC (Adaptive Cruise Control)-based traffic control strategy is presented, which improves the motorway traffic flow efficiency by changing in real time the driving behaviour (specifically the employed time-gap and the acceleration strength) of ACC-equipped vehicles in motorway sections according to the corresponding traffic conditions. The control strategy comprises three distinct actions: (i) gradual decrease of ACC time-gaps at near-capacity traffic in order to increase capacity; (ii) minimum time-gaps and (iii) acceleration increase, both at the very vicinity of active bottlenecks in order to increase the discharge flow. The behaviour and impact of the control strategy, and of each of its parts separately, are demonstrated for different ACC penetration rates via microscopic simulation applied to a real motorway stretch. The simulation results show that, even for low penetration rates of ACC-vehicles, the proposed strategy leads to sensible improvements regarding the average vehicle delay and fuel consumption by delaying the onset of congestion (thanks to increased capacity); and by speeding up its dissolution (thanks to the mitigation of capacity drop).

提出了一种基于ACC（自适应巡航控制）的交通控制策略，该策略通过实时更改配备ACC的车辆在高速公路路段的行驶行为（特别是使用的时间间隔和加速强度）来提高高速公路的交通效率根据相应的交通情况。该控制策略包括三个不同的动作：（i）逐渐减少接近容量交通的ACC时间间隔以增加容量；（ii）最小时间间隔和（iii）加速度都在活动瓶颈附近增加，以增加排放流量。通过应用于实际高速公路路段的微观模拟，证明了针对不同ACC渗透率的控制策略及其各个部分的行为和影响。仿真结果表明，即使对于ACC车辆的低渗透率，所提出的策略也可以通过延迟拥堵的发生（由于容量增加）而在平均车辆延误和燃油消耗方面带来合理的改进。并通过加快其解散速度（由于缓解了容量下降的影响）。
