山区公路感应式道路交通标志设计

Design of induction-based traffic signs on mountainous highway

山区公路弯道路段因其线形的特殊性,恶性交通事故频发,一直以来都是公路安全改善工作的重点和难点,严重制约着公路整体安全水平的提高.以往关于这一领域的研究多从被动防护的角度考虑,提出的改进措施作用有限,可操作性有限.因此,亟需探索一种新型的、低成本的、能够解决根本问题的新方法来解决这一问题.本文从主动防护的角度出发,提出感应式道路交通标志的设计,通过前置安装的检测器实时动态监视弯道路段驾驶员视距范围以外的道路交通状况,及时在标志板上显示路况动态信息,以便驾驶员及时、准确、果断采取适当的决策,避免事故的发生,希冀弥补现有静态标志的不足,改善由于视距不良带来的问题,提高公路整体安全水平.

Mountainous highway seriously restricts highway＇s level of safety because of its special linear and frequent serious traffic accident,and have always been the difficulty and emphasis on the improvement of highway safety.In the past,research on mountainous highway safety was attached to passive safety design,but the improvements were poor effects and operation.It is necessary to develop a new and low-cost method to solve the problem.In this paper,based on initiative method,design of induction traffic sign was proposed.The detector installed in the front could dynamically monitor the opposing traffic information of curve which is out of driver＇s sight distance.Through dynamic traffic sign information,drivers could take appropriate measures promptly and accurately to avoid traffic accident.The research makes up for static signs＇ shortcoming and solve problems caused by poor sight distance and then improve the overall level of safety for highway system.
