| 摘 要： | 目前我国相关规范并没有对高速公路改扩建作业区的布设做出相应的规定,施工中的一些不合理设置大大降低了作业区的通行能力和运行效率,并且存在诸多安全隐患。针对这一问题,运用交通仿真技术对双向四车道高速公路基本路段的通行能力以及作业区各主要控制区段（如预告段、合流段等）的长度进行研究分析,得到高速公路改扩建期作业区的长度设置标准和布设要求,为今后高速公路改扩建工程作业区的设置提供参考。

| Abstract: | Currently,no guidelines have been drafted for the work zone configuration of the reconstructed expressway in our country.Work zone capacity,safety and operation efficiency have been greatly reduced due to the irrational layouts.Applying traffic simulation technique,capacity on basic section of the reconstructed bidirectional four-lane expressway and the length range of the main influence sections of work zone（like Advance Warning Area,Merging Area,etc.） have been studied to achieve the length standard and arrangement requirement,which may be used for reference for work zone configuration of expressway reconstruction in the future. |
