| 摘 要： | 沙尘暴是影响沙漠高速公路交通安全的重要因素。基于对沙漠公路风沙危害数据库系统的分析研究，从信息采集系统、通讯系统、决策系统和执行系统等4个方面进行了沙尘监控系统的结构设计，还对该系统的可行性做了分析。该系统通过对沙尘天气能见度、危害度的检测和分析评判，可结合有关模型计算出安全行驶限制车速，以诱导交通。

| Abstract: | The sandstorm is an important factor that influences the traffic safety of desert expresways. The structure of the sand monitoring system which is based on the analysis and study of the Database System of Wind-Sand Hazard along the desert highway is designed from the information collection system, the communication system, the decision system, and the execution system. The feasibility of this system is also analyzed. Through checking, analyzing, judging the visibility and hazard in the air full of sands, this system can try to calculate the safe restrictive velocity of vehicles using the concerned mathematical model to induce the transportation. |
