| 摘 要： | 普通公路安全预警尤其是山区公路安全预警,由于其交通流的复杂性使得利用监控系统检测交通状态较为困难。离散选择分析模型通过原始数据直接做出判断,又可以根据数据更新系统进行有效的自身学习,因此较目前应用的贝叶斯网络模型更适用于山区公路安全预警。首先利用离散选择分析方法建立了道路交通状态检测的判断模型;其次以检测结果为基础,利用线性神经网络模型建立了路段交通预警模型;最终建立了山区公路安全预警系统。

| Abstract: | Because of the complexity of traffic flow,the traffic state detection of normal highway safety forewarning,in particular,a mountain road safety one,which makes use of the data obtained from the monitoring system,is more difficult.Discrete Choice Analysis Model makes judgments directly with the primal data,and learns itself efficiently by the Data Update System,therefore,it's more suitable for roads in the mountainous areas of the judgments than Bayesian Network Models which are most widely used at present.F... |
