The invention discloses a road black spot prediction model based on a bus CAN bus, and belongs to the technical field of line safety on-line analysis, and the construction of the road black spot prediction model based on the bus CAN bus comprises the following specific implementation steps: selecting data, extracting key information features, carrying out road network segmentation, and carrying out road black spot prediction. Step 3, extracting key information, constructing a prediction model, training the capability of the prediction model, carrying out acceptance inspection on the prediction model, and putting into use: based on the training result of the step 3, selecting the prediction model which is qualified in training, and putting into use the prediction model. According to the method, historical characteristics of various different accidents can be combined, weights of story influence factors in the historical characteristics are extracted, then new black spot data are predicted, the coincidence degree of a prediction result and an actual result in a prediction system is improved, the dynamic safety of a predicted bus route is improved, and the practicability of a prediction model is guaranteed.

    本发明公开了基于公交车CAN总线的道路黑点预测模型,属于在线路安全性在线分析技术领域,基于公交车CAN总线的道路黑点预测模型,该种预测模型在构建时的具体实施步骤包括:选择数据,并提取关键信息特征、进行道路网络分割,并提取关键信息、构建预测模型,并训练预测模型的能力和进行预测模型的验收,并投入使用:基于步骤三的训练结果,选择训练合格的预测模型,然后将预测模型投入使用。它可以结合多种不同事故的历史特性,并提取历史特性中的故事影响因素的权重,进而预测新的黑点数据,提高预测系统中预测结果和实际结果的符合程度,提高预测公交线路的动态安全性,保证了预测模型的实用性。
