Speed management is essential for ensuring the operating safety of highclassified highway. This paper discusses the setting, dissemination and implementation of speed limits based on the current state of speed management in China, and points out the concept of dynamic speed limits and the method of setting the dynamic speed limits according to highways characteristics, traffic volume, weather condition and accidents history. Finally, the paper puts an emphasis on the importance of traffic safety culture to the implementation of speed limits.

摘要

应用三维有限元动力学的基本方法，结合NEWMARK积分方法逐步求解运动方程，对动载（FWD荷载）作用下多层弹性体系的响应进行了分析，并将计算结果和理论结果进行对比，表明计算模型合理，计算结果准确。利用上述计算模型，对于多种路面结构研究其在不同荷载周期下的动态反应规律。

摘要

The generally road safety situation of highway net was evaluated through investigating road safety of some highways and analyzing accident patterns and causes. Some sections with high accident rate were found using road black spot identification technology. Then, accident causes related to highway features and traffic factors were analyzed. The characteristics of typical black spots were analyzed from the aspect of highway features and traffic devices. Running speed of vehicles on highways was measured in order to explain why over-speed driving always was primary accident cause.
