The embodiment of the invention provides a road traffic safety model generation and state prediction method and device, and the method comprises the steps: obtaining the historical traffic data of a road, constructing a road traffic safety model based on the historical traffic data, operating the road traffic safety model, obtaining a traffic prediction index, obtaining a traffic truth value index corresponding to the historical traffic data, and obtaining the state of the road traffic safety model. And obtaining an adjusted road traffic safety model under the condition that the difference between the traffic truth value index and the traffic prediction index meets the difference condition, otherwise, adjusting the model parameters of the road traffic safety model until the difference between the traffic prediction index and the traffic truth value index of the adjusted road traffic safety model meets the difference condition, and obtaining the road traffic safety model. And obtaining an adjusted road traffic safety model. The traffic indexes can be predicted through the road traffic safety model, the conflict number is obtained, and road traffic safety evaluation can be realized based on the conflict number.

    本申请实施例提供了道路交通安全模型的生成、状态的预测方法及装置,通过获取道路的历史交通数据,基于历史交通数据构建道路交通安全模型,运行道路交通安全模型,得到交通预测指标,获取历史交通数据对应的交通真值指标,在交通真值指标与交通预测指标的差异满足差异条件的情况下,得到调整好的道路交通安全模型,否则,调整道路交通安全模型的模型参数,直至调整后的道路交通安全模型的交通预测指标与交通真值指标的差异满足差异条件,得到调整好的道路交通安全模型。通过道路交通安全模型可以对交通指标进行预测,得到冲突数,基于冲突数可以实现道路交通安全评价。
