The invention discloses a road closed state detection method and device, computer equipment and a storage medium, and the method comprises the steps: carrying out the track point recall of each road section in an initial road section set, and converting the recalled track points into a plurality of road section sequences; the road section sequences are divided into a first sequence group and a second sequence group, the first sequence group comprises the target road section, and the second sequence group does not comprise the target road section; determining a track point feature sequence corresponding to the road section sequence of which the length is a preset length; performing coding processing on the track point feature sequence, and performing feature fusion on the coded track point features in the first sequence group and the second sequence group to obtain an expression feature corresponding to the target road section; and based on the expression features of the target road section, predicting that the target road section is in an open/closed state. The method improves the expression capability of the complexity of the road network, and improves the classification prediction timeliness and accuracy.
本发明公开了道路封闭状态检测方法、装置、计算机设备及存储介质,其方法实现,包括:对初始道路路段集合中各道路路段进行轨迹点召回,并将召回的轨迹点转换为若干道路路段序列;将若干道路路段序列划分为第一序列组和第二序列组,第一序列组包括目标道路路段,第二序列组不包括所述目标道路路段;确定长度为预设长度的道路路段序列对应的轨迹点特征序列;对轨迹点特征序列进行编码处理,并将第一序列组与所述第二序列组中编码后轨迹点特征进行特征融合,以得到目标道路路段对应的表达特征;基于目标道路路段的表达特征,预测得到目标道路路段处于开通状态/封闭状态。提高对路网复杂性的表示能力,提升了分类预测时效性和准确性。
