The invention discloses a travel time prediction method and device. The method comprises the steps that historical traffic data sets of N batches of a target road section are acquired, the historicaltraffic data set of each batch comprises recorded historical traffic data of a preset time period, and the historical traffic data at least comprise average historical travel time; taking the historical traffic data sets of N batches as the input of a convolutional neural network, and obtaining at least one probability value set through the convolutional neural network, the number of probability values in the probability value set being N; for a set of probability values, each probability value in the set of probability values is multiplied by its corresponding N average historical travel times in the historical transit data and the sum of the products is determined as a predicted travel time. By adopting the technical scheme provided by the invention, the travel time of the road section can be accurately predicted, so that the accuracy of the navigation route ETA is ensured.

    本发明公开了一种旅行时间预测方法及装置。所述方法包括:获取目标路段的N个批次的历史通行数据组,每个批次的历史通行数据组包括已记录的预设时间段的历史通行数据,所述历史通行数据至少包括:平均历史旅行时间;将N个批次的历史通行数据组作为卷积神经网络的输入,通过卷积神经网络得到至少一个概率值组,所述概率值组中的概率值个数为N;针对一个概率值组,用该概率值组中的每一个概率值与其在历史通行数据中对应的N个平均历史旅行时间相乘并将乘积的和值确定为预测旅行时间。采用本发明提供的技术方案能够准确地预测路段的旅行时间,从而确保了导航路线ETA的准确性。
