Abstract

According to the previous research, lane-changes are a major cause of serious traffic accidents. Thus, it is essential to build an efficient prediction algorithm for vehicles lane change on Advanced Driving Assistance System (ADAS) to ensure a safe and comfort driving for host vehicle. At present, many methods for lane change prediction have been proposed. However, most of them require a lot of data training to have a good prediction performance. Considering the practical applicability of the prediction algorithm in ADAS, this paper proposes a prediction method by probabilistic modelling. This method combines two aspects lane change evidence. On the one hand, model the lane change probability caused by the target vehicle's driving context. On the other hand, model the lane change probability reflected by vehicle posture in the road. The evaluation of the whole algorithms was done by using simulation data and real lane change data. The results show that the algorithm performs well in predicting accuracy and reducing false alarms.
一种基于概率建模的变道预测算法
根据以往的研究,变道是造成严重交通事故的一个主要原因。因此,在高级驾驶辅助系统(ADAS)上建立一种高效的车辆变道预测算法是保证主车辆安全舒适驾驶的关键。目前,人们提出了许多变道预测方法。然而,它们中的大多数都需要大量的数据训练才能具有良好的预测性能。考虑到预测算法在ADAS中的实际适用性,本文提出了一种基于概率建模的预测方法。该方法结合了两方面的变道证据。一方面,对目标车辆行驶环境引起的变道概率进行建模;另一方面,对道路上车辆姿态反映的变道概率进行建模。利用仿真数据和实际变道数据对整个算法进行了评价。结果表明,该算法在预测精度和减少误报方面有较好的效果。
