元胞自动机（CA）建模扩展到研究在发展中国家观察到的异构流量。在异质交通中，不同车辆的物理和机械特性差异很大，这反过来又导致了复杂的交通行为，从而导致无车道纪律。这种性质的异构流量建模的帮助下，改进的离散CA模型。在开发CA模型的基本结构中使用的方法的详细描述和修改后的方法用于生成不同的交通场景。从结果中，它是观察到的帮助下，简单的更新规则沿着与典型的异构交通特征的区域，该模型是能够再现真实的交通行为。一个额外的优点是，CA模型的修改后的结构也可以用来提取一些基本的流量特性，这是有用的，在理解异构的流量行为。最后利用现场实测的流量和占有率关系对仿真模型进行了验证。
Cellular Automata (CA) modelling is extended to study the heterogeneous traffic observed in developing countries. In heterogeneous traffic, the physical and mechanical characteristics of different vehicles vary widely which in turn leads to complex traffic behaviour resulting in no-lane discipline. This nature of the heterogeneous traffic is modelled with the help of an improved discrete CA model. A detailed description of the methodology used in developing the basic structure of the CA model is presented and the modified methodology is used to generate different traffic scenarios. From the results, it is observed that with the help of simple updating rules along with typical heterogeneous traffic characteristics of the region, this model is able to reproduce real traffic behaviour. An added advantage is that the modified structure of the CA model can also be used to extract some basic traffic characteristics which are useful in understanding the heterogeneous traffic behaviour. The simulation model is finally validated using the flow and occupancy relationship obtained from the field.
