Tickets for the direct train from Shanghai to Chongqing are hard to get. Is it possible for the passengers to take the bullet train from Shanghai to Wuhan and transfer to the high-speed train to Chongqing? Is it possible to achieve the same result as the popular routes by connecting and transferring among not so popular routes when all the tickets of popular trains are sold out? At the 2014 Shanghai College Students “Creation Cup” Contest organized by Tongji University, the “Optimization and Realization of Comprehensive Train Transfer System” led by Ma Chengyuan, a sophomore in the School of Transportation Engineering of Tongji provided a new way of thinking and possibility for solving the challenges in getting train tickets during the Spring Festival travel rush. The project won the “Most Popular Award”.
During the Spring Festival, many people have to rack their brains to get the train ticket to go back to their hometowns. “Even if it is difficult to get the tickets to popular stations, it does not mean all the tickets to all stations are sold out. That is to say, there are still some seats available on some trains when other trains are fully packed,” said Ma. As the capacity of direct trains between popular stations is limited, transfer will not only solve the ticket problem for passengers but also improve the operating efficiency of not so popular trains. As transfer is very complicated, it is not easy for passengers to find out the best and most feasible routes. Therefore, Ma and his classmates decided to do a research on the rain transfer system.
The calculation method is the key of the research so as to find out all possible transfer routes first and then find out routes with available seats for passengers in a short period of time. The team kept modifying and optimizing the calculation methods so as to get the simplest and most accurate one. They even developed the train transfer system into software to make the calculation tangible. “The train transfer system as the finished product can make use of the existing website of China Railway, research and analyze data of stations and trains, etc.,” said Ma.
Is it possible to put this product into use in the coming Festival? The answer is negative as the conditions are not mature. Ma said the software still needs upgrading and the core issue is information collection and optimization. The team hopes passengers can use the software to look for the routes before they book their tickets. If there is no direct route or the tickets for the direct train are sold out, the transfer system can offer one or two best transfer plans.
