非常规干道交叉口设计（UAID）作为一种新的解决方案，可以有效地提高平面信号交叉口的运行和安全性能，一直被提倡使用。一些研究表明，艾滋病可以导致更高的能力，更低的延误和更少的崩溃。此外，这些“非传统”设计具有成本效益，因为通常只需要微小的几何修改。近年来，开展了大量有价值的研究工作，以讨论分析艾滋病毒/艾滋病预防和控制系统的操作和安全性能的方法。然而，这些研究很少，目前没有集体努力来确定艾滋病分析的基本原则，并确定目前方法中的差距。本文提出了一个深入的文献回顾现有的方法分析非常规交叉口设计的操作和安全性能。这些方法在原则性问题（如目标和范围）和技术性问题（如实验设计、分析工具和评价方法）上有所不同。在回顾方法的基础上，确定了需要进一步研究和改进的领域。
The use of unconventional arterial intersection designs (UAIDs) has been advocated as a novel solution that can efficiently enhance the operational and safety performance of at-grade signalised intersections. Several studies suggest that UAIDs can lead to higher capacity, lower delays and fewer crashes. As well, these ‘non-traditional’ designs are cost-effective as only minor geometric modifications are usually required. In recent years, there has been considerable valuable research work undertaken to discuss methods for analysing the operational and safety performance of UAIDs. Nevertheless, these studies are sparse and no collective effort is currently available to identify the basic principles of the analysis of UAIDs and to determine gaps within the current methods. This article presents an in-depth literature review of existing methods of analysing the operational and the safety performance of unconventional intersection designs. These methods differ in principle issues, such as objective and scope, and in technical issues, such as experimental design, analysis tools and evaluation measures. Based on the reviewed methods, areas that need further research and improvements are identified.
