考虑到美国基础设施的老化和高速公路工作区数量的预期增长，研究提高工作区流动性和安全性的方法非常重要。数据表明，不适当的合并操作是高速公路工作区撞车的一个主要因素，往往导致严重的拥堵和延误。本研究提出了一个新英格兰合并（NEM）的高速公路工作区控制，这需要车辆的行为合作，创造安全的合并间隙时，接近车道关闭点造成的工作区。基于VISSIM微观模拟考虑不同的输入交通需求，NEM进行了比较，晚合并，早合并，没有控制的平均延误，平均旅行时间，和吞吐量。此外，NEM的安全性能进行了分析，使用替代安全措施，如车辆轨迹，密度，加速度，和车头时距。在这项研究中，一个典型的类型的公路工作区建模，这代表了一个双车道公路与右车道关闭。建模结果表明，整体NEM显着优于所有其他合并控制方法的安全性和流动性措施。与后期合并和早期合并类似，实现NEM将受益于驱动程序的合作。NEM的适用性可以随着协作自适应巡航控制（即，1级自动化）技术。
Given the aging infrastructure and the anticipated growing number of highway work zones in the United States, it is important to investigate methods to improve work zone mobility and safety. Data suggests that inappropriate merge maneuvers are a major contributing factor to highway work zone crashes that often lead to severe congestion and delay. This research proposes a New England Merge (NEM) for highway work zone control, which requires vehicles to behave cooperatively and create safe merging gaps when approaching lane closure points caused by work zones. Based on VISSIM microscopic simulations considering varying input traffic demands, the NEM is compared with late merge, early merge, and no control in terms of average delay, mean travel time, and throughput. Additionally, the safety performance of NEM is analyzed using surrogate safety measures such as vehicle trajectory, density, acceleration, and distance headway. A typical type of highway work zone is modeled in this study, which represents a two-lane highway with the right lane closed. The modeling results show that overall NEM significantly outperforms all other merge control methods in terms of both safety and mobility measures. Similar to late merge and early merge, implementing the NEM would benefit from driver cooperation. The applicability of NEM can be substantially improved with the wide adoption of cooperative adaptive cruise control (i.e., level 1 automation) technology.
