摘要
超速行驶是道路交通事故的重要诱因之一。提出点车速和线车速的研究理念,分析其与交通安全的关系,在此基础上对减速标志标线和减速带的减速机理及特征进行研究,并结合驾驶员心理效应提出控速措施,最后对减速带横断面轮廓曲线进行了较为详细的设计研究,可为道路设计和管理部门提供相关理论依据与可行方法。
Over-speed has a direct impact on road traffic accidents and it is one of the important factors of traffic accidents The paper poses the research concept of point speed and line speed, analyzes the relationship between speed and safety, studies the speed - controlling mechanism and characteristics of decelerated signs, decelerated marking and speed-control hump based on the relationship. It proposes several measures to control speed based on the driver psychological effects At last, it discusses a more detailed design method of the speed- control hump curve to provide the theoretical basis and practical method for road design and management.
