Abstract

In this study, we employed the general formula of the delay per vehicle for the case of one link at two intersections as a function of the link length and offset of traffic signals at two adjacent intersections with the general value of green splits under arbitral demand condition without oversaturation. The highest and lowest coordination efficiencies are defined for different link lengths. The nature of the link lengths and offsets that provide minimum delay per vehicle were analyzed and demonstrated. Additionally, two types of extensions to this study were conducted by determining the effects of an additional intersection located in the middle of the target link and for the installation at two adjacent intersections outside the target link.

主干道信号交叉口协调效率的基本理论

在本研究中，我们采用任意需求条件下，在不过饱和的情况下，将两个交叉口的一条链路情况下的每辆车延误的一般公式作为相邻两个交叉口的链路长度和交通信号偏移量的函数，并具有绿灯分隔的一般值。对于不同的链路长度，定义了最高和最低的协调效率。分析和论证了提供每辆车最小延迟的链路长度和偏移量的性质。此外，本研究还进行了两种类型的扩展，通过确定位于目标路段中间的额外交叉口的效果，以及在目标路段外的两个相邻交叉口安装的效果。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
