The road passenger transportation enterprise is a complex system, requiring a clear understanding of their active safety situation (ASS), trends, and influencing factors. This facilitates transportation authorities to promptly receive signals and take effective measures. Through exploratory factor analysis and confirmatory factor analysis, we delved into potential factors for evaluating ASS and extracted an ASS index. To predict obtaining a higher ASS information rate, we compared multiple time series models, including GRU (gated recurrent unit), LSTM (long short-term memory), ARIMA, Prophet, Conv_LSTM, and TCN (temporal convolutional network). This paper proposed the WDA-DBN (water drop algorithm-Deep Belief Network) model and employed DEEPSHAP to identify factors with higher ASS information content. TCN and GRU performed well in the prediction. Compared to the other models, WDA-DBN exhibited the best performance in terms of MSE and MAE. Overall, deep learning models outperform econometric models in terms of information processing. The total time spent processing alarms positively influences ASS, while variables such as fatigue driving occurrences, abnormal driving occurrences, and nighttime driving alarm occurrences have a negative impact on ASS.
道路客运企业是一个复杂的系统,需要清楚了解其主动安全状况(ASS)、趋势及影响因素。这有助于运输当局及时接收信号并采取有效措施。通过探索性因素分析和验证性因素分析,我们深入研究了评估ASS的潜在因素,并提取了一个ASS指标。为预测获得更高的ASS信息率,我们比较了多个时间序列模型,包括门控循环单元(GRU)、长短期记忆网络(LSTM)、自回归积分滑动平均模型(ARIMA)、先知(Prophet)、卷积长短期记忆网络(Conv_LSTM)和时间卷积网络(TCN)。本文提出了水滴算法-深度信念网络(WDA-DBN)模型,并使用深度夏普力值(DEEPSHAP)来识别具有较高ASS信息含量的因素。TCN和GRU在预测方面表现良好。与其他模型相比,WDA-DBN在均方误差(MSE)和平均绝对误差(MAE)方面表现最佳。总体而言,深度学习模型在信息处理方面优于计量经济模型。处理警报所花费的总时间对ASS有正向影响,而诸如疲劳驾驶发生次数、异常驾驶发生次数和夜间驾驶警报发生次数等变量对ASS有负面影响。
