面向智慧公路的智能道钉应用场景研究

Research on Application Scenarios of Intelligent Road Studs For Smart Highway

我国智能公路的建设近年来获得飞速发展,针对当前智慧公路在信息感知发布方面存在的一些问题,在开展了大量研究与市场产品对标的基础上,提出了一种新型智能道钉设备,分析了智能道钉在智慧公路上应用的优势与可行性,介绍了智能道钉的系统架构与设备内部结构。针对公路雾区、小半径弯道、高速公路分流区等视距受限路段,提出了针对以上场景的智能道钉发布预警功能的实现,并在实地搭建模拟测试环境,测试了公路雾区、小半径弯道等应用场景。结果表明,通过智能道钉能够在不良视距路段实现对驾驶人的事故风险警示,弥补可变情报板等设备的不足,优化预警手段,实现碰撞风险的精细化提示,从而减少由不良视距造成的行车安全隐患。

The construction of smart highway in China has developed rapidly in recent years. Aiming at some problems existing in the information perception and release of smart highway, in the paper a new type Intelligent Road Stud is put forward based on a number of research and market product benchmarking, and the advantages and feasibility of intelligent stud in smart highway are analyzed. The system architecture and equipment internal structure of intelligent stud are introduced. For the sections with limited sight distance such as highway fog area, small radius curve and highway diversion sections, the intelligent stud can release early warning in case of the above scenarios, and a simulation test environment is built in the field to detect the application scenarios such as highway fog area and small radius curve. The results show that use intelligent stud can realize the accident risk warning to drivers in the section with bad sight distance, make up for the deficiency of variable information board and other equipment, optimize the early warning means, and realize the fine prompt of collision risk, so as to reduce the hidden danger of driving safety caused by bad sight distance.
