The invention discloses a parking space vacancy rate prediction method and device, a medium and equipment, and the method comprises the steps: inputting the parking space vacancy rate of each parking lot in a to-be-predicted region before a to-be-predicted moment into a feature extraction network of a parking space vacancy rate prediction model; and obtaining a first feature used for representing the relationship between the parking space vacancy rate and the time of each parking lot. And inputting the spatial relation graph of each parking lot in the to-be-predicted area and the first feature into a graph fusion network to obtain a fusion feature. And inputting the fusion features into a result prediction network to obtain the parking space vacancy rate of each parking lot in the to-be-predicted area at the to-be-predicted moment. Based on the relationship between the parking space vacancy rate and the time, the relationship between the parking space vacancy rate and the space, and the potential interaction relationship between the parking space vacancy rate and the time and the space, the parking space vacancy rate prediction results of the plurality of parking lots in the to-be-predicted area are obtained at the same time, and the prediction efficiency of the parking space vacancy rate and the accuracy of the prediction results are improved.

    本说明书公开了一种停车位空闲率的预测方法、装置、介质及设备,可将待预测时刻之前的待预测区域内的各停车场的停车位空闲率输入到停车位空闲率预测模型的特征提取网络,得到用于表征各停车场的停车位空闲率与时间关系的第一特征。以及将待预测区域内的各停车场的空间关系图以及该第一特征输入到图融合网络,得到融合特征。进而将融合特征输入到结果预测网络,以得到在待预测时刻待预测区域内的各停车场的停车位空闲率。基于停车位空闲率与时间的关系,停车位空闲率与空间的关系,以及停车位空闲率与时间和空间的潜在交互关系,同时得到待预测区域内的多个停车场的停车位空闲率预测结果,提高了停车位空闲率的预测效率和预测结果的准确性。
