Problems solved by technology

However, due to technical limitations, the output interface and human-computer interaction interface of many traffic simulation software are not perfect, and the description of the output interface is mostly rough
For example, traffic micro-simulation software almost all uses simplified cuboids to represent vehicles, and only uses different colors to distinguish vehicle types; in the expression of urban environments, most of the current simulation software can only achieve rough expressions in geometric forms. Light source settings, material design, etc. are lacking, so it is impossible to produce a sufficiently detailed city model
Due to this limitation, it is impossible to realize the true reproduction and factual simulation of urban traffic by traffic simulation software in detail
