本申请公开了一种车道交通流量数据补全方法及其装置,涉及人工智能、智能交通及深度学习等领域。具体实现方案为:获取交叉路口内车道的属性信息和车道在第一时间段内观测到的交通流量数据;根据该属性信息和车道在第一时间段内观测到的交通流量数据,生成车道交通流量综合空间表示;根据车道在第一时间段内观测到的交通流量数据,获取车道交通流量全局分布的嵌入表示;根据车道交通流量全局分布的嵌入表示,获取车道交通流量时间关系表示;根据车道交通流量综合空间表示和车道交通流量时间关系表示,对交叉路口的车道交通流量之中缺失数据进行补全操作。本申请可以对城市多车道的交通流量的缺失数据进行补全,有效提高交通流量数据补全的准确性。
The invention discloses a lane traffic flow data completion method and device, and relates to the fields of artificial intelligence, intelligent traffic, deep learning and the like. According to the specific implementation scheme, attribute information of lanes in an intersection and traffic flow data observed by the lanes in a first time period are acquired; generating lane traffic flow comprehensive space representation according to the attribute information and traffic flow data observed by the lane in the first time period; according to the traffic flow data observed by the lane in the first time period, obtaining the embedded representation of the global distribution of the traffic flow of the lane; obtaining a lane traffic flow time relation representation according to the embedded representation of the global distribution of the lane traffic flow; and complementing missing data in the lane traffic flow of the intersection according to the lane traffic flow comprehensive space representation and the lane traffic flow time relation representation. According to the invention, missing data of urban multi-lane traffic flow can be complemented, and the accuracy of traffic flow data complementation is effectively improved.
