文章选取了中国行业规程JTG H30和美国规程MUTCD作为研究对象,比较两者在作业区长度和限速方面的区别,找到影响作业区行车安全和通畅的主要因素,利用微观仿真软件VISSIM对2种规程方案进行仿真模拟,对JTG H30进行相关因素的优化并比较优化效果,指出JTG H30的改进思路和优化方向,为进一步补充和完善JTG H30奠定基础。根据研究结果,通过不同影响因素的改变,解决养护维修作业区相应的安全性和通畅性问题,提高我国的公路养护管理水平。
This article chooses JTG H30 in China and MUTCD in USA as the research object, compares the difference between the two in length and speed limit, finds the main factors that affect the safety and smoothness of driving in the work area, and uses the micro-simulation software VISSIM The simulation and simulation of the protocol are carried out. The related factors of JTG H30 are optimized and compared, and the improvement ideas and optimization direction of JTG H30 are pointed out, laying a foundation for further supplementing and perfecting JTG H30. According to the results of the study, through the changes of different influencing factors, the corresponding safety and patency problems of maintenance and repair work area are solved, and the level of highway maintenance and management in our country is raised.
