阿肯色州公路和运输部(AHTD)于2000年春天开始实施“爱荷华州织”，即通过左合并和车道转移关闭车道。采用该技术的主要目的是在加快施工进度的同时，提高交通安全。AHTD的期望是，通过提供一致的车道关闭(总是将车辆合并到左侧)，他们将提供更大的预期和司机的合规性，从而减少碰撞。尽管已经努力分析了爱荷华州的编织，但这种编织图案对农村四车道州际公路路段的安全影响还没有很好的记录，那里通常是工作区车道关闭的地方。为了解释这一点，对车道关闭策略和工作区碰撞以及其他影响变量的相关性进行了分析。这项研究的目的是根据实际的撞车经验，量化爱荷华州编织与传统右车道关闭对农村高速公路路段的安全影响。这些分析的结果是按以下顺序排列的：1)坠机频率；2)坠机率；3)坠机严重程度。虽然爱荷华州织造和常规右手闭合的工作区域撞车总数和撞车严重程度的变化没有显著差异，但发现爱荷华织造的撞击率比常规右手闭合低46%，这是一个具有统计学意义的发现。
The Arkansas State Highway and Transportation Department (AHTD) began the implementation of the “Iowa weave,” or lane closure with a left-hand merge and lane shift for their Interstate Rehabilitation Program (IRP) in the spring of 2000. The main objective of incorporating this technique was to speed up the construction progress, while improving traffic safety. It was the AHTD’s expectation that by providing consistent lane closures (always merging traffic to the left) they would provide greater expectancies and compliance by drivers, resulting in fewer crashes. Although efforts have been made to analyze the Iowa weave, the safety implications of this weave pattern on rural four-lane Interstates section, where work zone lane closures are generally situated is not well documented. To account for this, an analysis on the correlation of lane closure strategies and work zone crashes along with other influential variables was examined. This study was aimed at quantifying the safety effects of the Iowa weave as opposed to conventional right-lane closure on rural freeway segments on the basis of actual crash experience. The findings of the analyses were organized by: 1) crash frequency; 2) crash rates; and 3) crash severity. While changes in the overall number of work zone crashes and the crash severity were found to be not significantly different between the Iowa weave and the conventional right-hand closure, it was found that the Iowa weave had a crash rate 46 percent lower than the conventional right-hand closure, which was a statistically significant finding.
