Problems solved by technology

Due to the complexity of the content covered by this problem and the many random factors involved, it is difficult to consider all the influencing factors to obtain the optimal solution of the system
Therefore, in the existing analysis process, some influencing factors are not considered or idealized, which also leads to the incompleteness of the existing research results, and there are still many deficiencies
It is usually manifested in the modeling research of transfer coordination problems under ideal conditions for simple road networks, which makes the established operation coordination optimization model distorted from the actual situation
