摘 要：随着社会的发展，道路交通安全的重要性日益提高，但目前由货车右转弯盲区造成的交通事故仍然让人触目惊心，为减少这一交通事故，国内外均采取了许多解决方法，但这些方法都过于固定和单一，并不能及时有效地实现货车右转盲区的预警。根据此情况，我们提出了一种基于车路协同的货车右转弯盲区预警系统，此系统从人、车、路三位一体的角度出发，通过安装雷达和检测器等设备采集信息，利用路侧单片机进行数据处理和计算，应用5G和V2N技术实现信息交互，从而达到全方位实时预警的效果。安全永远是一个国家交通发展的重中之重，此系统的提出将更有效地提高货车驾驶的安全性，减少货车右转过程中交通事故的发生。

Early Warning System for Blind Spots in Right Turning of Trucks Based on Vehicle-Road Coordination

Abstract：With the development of society， the importance of road traffic safety is increasing. However， the current traffic accidents caused by the blind spot of trucks turning right are still shocking. In order to reduce this traffic accident， many solutions have been adopted at home and abroad， but these methods are too fixed and single， and cannot effectively realize the early warning of the blind spot of the right turn of the truck in a timely and effective manner. According to this situation， we propose a right-turn blind zone warning system for trucks based on vehicle-road coordination. This system starts from the perspective of the trinity of people， vehicles， and roads. It collects information by installing radar and detectors， and uses roadside single-chip microcomputers to collect information， data processing and calculation， application of 5G and V2N technology to achieve information interaction， so as to achieve the effect of all-round real-time early warning. Safety is always the top priority of a country's transportation development. The proposal of this system will more effectively improve the safety of truck driving and reduce the occurrence of traffic accidents during the right turn of trucks.

Key words：traffic engineering， vehicle-road coordination， right turn blind spot for trucks， early warning system

1 引言

道路交通安全一直是人們关注的重中之重，其中货车更是因为其自身更大的质量、更小的灵活性，占据不安全车辆的榜首。据不完全统计，每年因大货车发生的交通事故占30%，大型货车交通事故死亡人数约占事故总死亡人数的70%，在对货车发生事故的位置进行调查后发现，右转弯盲区发生事故的概率达86%。

由此可以看出，货车交通事故具有发生率高、死亡人数多的特点，货车右转盲区是货车事故的高发点，也是减少货车交通事故、提高道路安全性的突破点。

目前，为了防止货车右转发生事故，我国采取了一些方法，例如设置警示牌、警示线来提醒行人，安装雷达传感器、超声波测距传感器等盲区预警设备以及提高货车驾驶员的驾驶水平等等。……
