Transport Supply-Demand Matching Evaluation Method of Taxi Transfer Passengers at External Transportation Hubs

In order to solve the problem of supply-demand mismatch between arrival passenger demand and transportation capacity supply due to the dynamic and random nature of passenger travel mode choice, a matching evaluation model for the supply and demand of taxi capacity at external passenger transportation hub was established. Firstly, the actual scenario of taxi transferring transportation at a hub was divided into two scenarios of sufficient taxi supply and insufficient taxi supply based on taxi queuing characteristics and taxi supply. Secondly, SBC(Stationary Backlog-Carryover) approach was considered into M/M/C queuing model. A taxi capacity supply and demand matching evaluation model was constructed from the actual taxi passenger queuing scenario combining taxi capacity, taxis number and queuing number of passengers, and the taxi supply and demand matching index (index value is 10 minutes) was introduced for comparison and analysis at the same time. Finally, the model was applied to the east dispatch station of Beijing South Railway Station to evaluate its supply-demand matching of taxi transportation, and the calculated average waiting time was compared with the actual measured average waiting time to verify the accuracy of the model. The results showed that the average waiting time of passengers during the evening peak hours of the survey day was 6.24 minutes, which was less than the index value, and the supply-demand matching situation was better; the average waiting time of passengers at night was 15.20 minutes, which was greater than the index value, and the supply-demand matching situation was worse. Accordingly, in the future, the hub management departments and the transferring transport enterprises can reasonably arrange the dispatch of taxis according to the real-time taxi supply and demand matching situation, so as to improve the capacity protection and emergency response capability of hubs, and realize the rapid and orderly evacuation of passengers.
