摘　　要：在交换随机减速和安全减速顺序的敏感驾驶交通流模型基础上,研究了驾驶激进系数的引入对交通流的影响.在保证安全距离的前提下,激进的驾驶人倾向于提高自身车速并紧随前车来提高自身的即时通行效率.道路上驾驶越激进的驾驶者越多,道路的通行效率越好.数值实验的结果表明相比于一般的交通流模型和敏感驾驶交通流模型,激进驾驶模型能够更进一步提高道路通行效率.此外,在宽运动阻塞区域,激进驾驶模型能够缓解大段阻塞区域的出现,并再现现实生活中的条纹式的阻塞现象.Based on the sensitive driving traffic flow model that exchanges random deceleration and safe deceleration sequence, the influence of the introduction of driving aggressiveness coefficient on traffic flow is studied. Under the premise of ensuring a safe distance, the more aggressive the driver, the more inclined to increase his own speed and close to the vehicle in front, thereby improving his immediate traffic efficiency. The more aggressive the driving on the road, the more efficient the road is. The results of numerical experiments show that compared with the general traffic flow model and the sensitive driving traffic flow model, the aggressive driving model can further improve the traffic efficiency in synchronous flow and wide moving jams. In addition, in the wide moving jams, the aggressive driving model can alleviate the appearance of large obstruction areas and reproduce the striped obstruction phenomenon in real life.
