Study On The Design Of Airport Bus Network

In recent years,with the increase of air passenger demand,the ground transportation system around the airport is facing great pressure,especially the utilization rate of public transportation represented by airport buses is in urgent need of improvement,and the phenomenon of road congestion occurs from time to time,which has caused a serious impact on road transportation and passenger travel experience.As a form of public transport,airport bus can effectively save social resources on the premise of satisfying passengers’ long-distance travel.Therefore,many scholars will continue to pay attention to how to efficiently utilize airport buses to provide impetus for the development of modern aviation industry.With the operation of Beijing Daxing International Airport,Beijing has officially entered the mode of dual-hub airport,and the function of the capital as a large aviation hub has become more prominent.To further improve the transportation ability of double airport in Beijing,develop the function of airport bus as mass transit.By reference to analyzing a large number of related literature at home and abroad,and combining with the actual situation of Beijing double airport landside traffic system,put forward a set of system of airport bus network design method,including the airport bus line and schedule design two questions.The main body of this study is divided into two parts.The first part is to improve the initial path generation method and route set optimization method of airport bus route by setting reasonable objective function and matching constraint condition and using improved fruit fly optimization algorithm.After that,the empirical study was carried out on two networks of different sizes of Beijing Capital International Airport and Beijing Daxing International Airport.The second part is to optimize the design of airport bus schedule considering passenger travel time.The average travel time of passengers is taken as the optimization target,and the number of departures is controlled as far as possible on the premise of fully meeting the travel needs of passengers.The algorithm mechanism of fruit fly optimization algorithm.was further improved to solve the scheduling problem,and the problem was solved on the actual network to verify the rationality and feasibility of the optimal design method of airport bus schedule.The effectiveness of the method is verified by comparing the basic drosophila algorithm.
