Present study reviews simulation models available for signalised and unsignalised intersections using cellular automata (CA). CA models are discrete dynamic systems, through which it is possible to model traffic behaviour with ease and simplicity. Thus, CA was chosen for the study. Driver, seepage behaviour and type of traffic (homogeneous/heterogeneous) affect the capacity and safety of the intersections. These models can be either with open boundary (with continuous deletion and generation of vehicles) or closed/periodic boundary (with a fixed number of vehicles). The proposed study also investigates about the boundary conditions of simulation models as these change the results of simulations. Further, frequent acceleration/deceleration activity at the intersection causes more emissions. It was found that most of the traffic simulation models developed for intersections lack in modelling interaction between vehicles, seepage, driver behaviour and emission behaviour etc. Very few studies were found to model the emission behaviour with CA. Present study chronologically lists studies with methods adopted, advancements in those methods, traffic behaviours taken into consideration and missing gaps between studies. The composition and interaction of five different modes such as cars, buses, trucks, motorised three-wheelers and motorised two-wheelers were considered as mixed traffic. A new methodology is suggested based on this review.

信号交叉口和无信号交叉口的元胞自动机模型，特别注意混合交通流：综述

本研究回顾了使用元胞自动机（CA）可用于信号交叉口和无信号交叉口的仿真模型。CA模型是离散的动态系统，通过它可以轻松，简单地对交通行为进行建模。因此，选择了CA进行研究。驾驶员，渗流行为和交通类型（同种/异类）会影响交叉口的通行能力和安全性。这些模型可以具有开放边界（具有连续删除和生成车辆）或具有封闭/周期性边界（具有固定数量的车辆）的模型。拟议的研究还研究了仿真模型的边界条件，因为这些条件改变了仿真结果。此外，交叉路口频繁的加减速活动导致更多的排放。结果发现，为交叉路口开发的大多数交通模拟模型都缺乏对车辆之间的相互作用，渗流，驾驶员行为和排放行为等进行建模的研究。很少有人研究使用CA对排放行为进行建模。本研究按时间顺序列出了所采用方法的研究，这些方法的进展，所考虑的交通行为以及研究之间的空白。汽车，公共汽车，卡车，机动三轮车和机动二轮车等五种不同模式的组成和相互作用被认为是混合交通。在此审查的基础上，提出了一种新的方法。本研究按时间顺序列出了所采用方法的研究，这些方法的进展，所考虑的交通行为以及研究之间的空白。汽车，公共汽车，卡车，机动三轮车和机动二轮车等五种不同模式的组成和相互作用被认为是混合交通。在此审查的基础上，提出了一种新的方法。本研究按时间顺序列出了所采用方法的研究，这些方法的进展，所考虑的交通行为以及研究之间的空白。汽车，公共汽车，卡车，机动三轮车和机动两轮车等五种不同模式的组成和相互作用被认为是混合交通。在此审查的基础上，提出了一种新的方法。
