The embodiment of the invention provides a method and device for acquiring intersection steering flow data and a storage medium . The method comprises the steps of acquiring bayonet vehicle passing data and road network data; according to the road network data, creating a checkpoint steering reachability matrix, wherein the checkpoint steering reachability matrix is used for representing reachability between checkpoints in all intersections in a road network; and calculating intersection steering flow data corresponding to each intersection in the road network based on the bayonet vehicle passing data and the bayonet steering reachable matrix. Therefore, large-scale, fine-time-granularity, low-cost and accurate intersection turning traffic flow data can be obtained.

    本申请实施例提供一种交叉口转向流量数据的获取方法、装置和存储介质,所述方法包括:获取卡口过车数据和道路网数据;根据所述道路网数据,建立卡口转向可达矩阵,其中,所述卡口转向可达矩阵用于表征道路网中的各个交叉口内的卡口之间的可达性;基于所述卡口过车数据和所述卡口转向可达矩阵,计算道路网中的各个交叉口各自对应的交叉口转向流量数据。如此,能够获取到大规模的、细时间粒度的、低成本的、准确的交叉口转向交通流量数据。
