随着公路交通运输业的发展,交通安全已成为社会关注的焦点问题。交通标志作为面向驾车人员提供信息的载体,在预防和减少交通事故方面发挥着重要的作用。论文分析了塔中山区公路交通标志存在的主要问题,在参考国内外关于山区公路交通标志设置研究的基础上,针对山区公路的特点,从人-车-路(环境)组成的道路交通系统出发,研究了驾驶人、车辆以及山区公路的交通环境(重点分析了山区公路小半径弯道、长大坡以及异常天气)对山区公路交通安全的影响,并提出了基于驾驶人信息需求的交通标志设置的要求。即提供整体性和预警性信息;弯道处实行大小车辆区别限速;长大坡路段交通标志的设置思路。并结合实际,论证了本论文研究的理论和方法的可行性。
With the development of highway transportation, traffic safety has become the focus of society. Traffic signs, as vehicles for providing information to motorists, play an important role in preventing and reducing traffic accidents. This paper analyzes the main problems existing in traffic signs of highway in Tazhong Mountain. Based on the research on the setting of traffic signs in mountainous areas at home and abroad, aiming at the characteristics of mountainous roads, this paper starts from the road traffic system consisting of people-vehicle-road (environment) , Studied the traffic environment of drivers, vehicles and mountainous roads (focusing on the analysis of small radius turns, long and large slopes of mountainous roads and abnormal weather) on road traffic safety in mountainous areas and proposed traffic signs based on driver information requirements Set the requirements. That is to provide a holistic and early warning information; the size of the vehicle at the corner of the implementation of the difference between the speed limit; long slope section traffic signs set ideas. Combined with the reality, this paper demonstrates the feasibility of the theory and method.
