The invention provides a vehicle operation dynamic risk assessment method considering time and space distance, the method is mainly divided into three parts, namely a time distance risk quantification module, a space distance risk quantification module and a risk superposition module, environment information around a target vehicle is collected through various devices, and the risk superposition module is used for carrying out risk assessment on the target vehicle through the time distance risk quantification module, the space distance risk quantification module and the risk superposition module. Position coordinates and relative speeds of the target vehicle and the surrounding vehicles are calculated based on the collected data; respectively calculating a time distance risk and a space distance risk of the target vehicle caused by other environmental elements at the current moment; summing the two risks generated by the single environment element according to the weight parameter, and taking the maximum value of the risks of all the environment elements suffered by the target vehicle to obtain the risk value suffered by the vehicle at the current moment; therefore, a basis is provided for further risk early warning and vehicle active control, and the traffic operation safety is improved.
本发明提出了一种考虑时间与空间距离的车辆运行动态风险评估方法,该方法主要分为三个部分,分别是时间距离风险量化模块、空间距离风险量化模块和风险叠加模块,通过各种设备采集目标车辆周围的环境信息,并基于采集的数据对目标车辆和周围车辆的位置坐标和相对速度进行计算;然后分别计算当前时刻其他环境要素对目标车辆造成的时间距离风险与空间距离风险;依据权重参数对单一环境要素所产生的两种风险求和,并对目标车辆所受到的全部环境要素风险取最大值,得到车辆当前时刻受到的风险值;从而为进一步风险预警与车辆主动控制提供依据,提高交通运行安全。
