One of the main fields I focus on is optimization of railway transportation. In order to improve the efficiency of railway transportation, with the help of mathematics and operational research, the complex logical relationship among elements of railway management could be transformed into some certain mathematical models. The existing or designed algorithm could be used to resolve them.
Another concentrated field is optimization of integrated transportation. The research is executed to improve the capacity of transportation passageway and the ability of market competition with other transportation modes.
Some up-to-date topics in traffic are also belonging to my research scope.
