Research On The Optimization Of Customized Tourist Bus Routes

With the continuous improvement of Chinese urbanization and the increasing living standards of the people,the rapid development of tourism has been achieved,and the development of tourism traffic is very important for serving tourists traveling.The layout of tourist bus special line can better meet the requirements of tourists for fast travel,comfortable travel,less transfer,high accessibility rate and city sightseeing.At the same time,it greatly reduces the traffic pressure such as passing and parking in scenic spots,which is conducive to reducing carbon emissions and improving the overall urban environment.Therefore,good tourist bus route planning has practical significance for the development of urban tourism and the improvement of urban bus system.For the phenomenon of uneven distribution of tourist attractions and polarization of tourist flow distribution in tourist cities,this study proposes a channeling customized tourism bus operation mode,which can reasonably channel tourist resources to balance tourist experience and promote the maximum utilization of urban tourism resources.Firstly,this paper reviews and analyzes literatures on tourism transportation,tourism route design,tourism public bus network,customized bus,etc.,and concludes that existing researches mainly focus on customized passenger transport,bus route optimization,tourism route design,etc.,while quantitative researches on tourist flow management in scenic spots are relatively few.Combined with the research of customized bus,tourism route and bus route optimization,this paper proposes the channeling customized tourism bus mode to alleviate the problem of passenger flow management in peak tourism periods.Secondly,this paper,starting from three aspects of tourist resources,tourist attractions and urban traffic,establishes a calculation model of attraction heat of scenic spots.Based on this,it constructs a tourist flow satisfaction rate index to evaluate the overall reception level of the overall tourist attraction resources.Then,based on the accessibility model,it constructs a tourist flow facilitation model between scenic spots and quantifies the external facilitation time between scenic spots.It provides the basis for the design of customized tourist bus routes.At the same time,the cluster of urban tourist attractions and central scenic spots are identified by clustering algorithm,which can meet the need of efficient operation of dredging routes.Then,two scenarios of the operation of the channeling customized tourism bus lines are analyzed,and the optimization model of the channeling customized tourism bus lines is established.Based on the benefit function of tourists’ tourism experience income and public transport operating cost,the channeling routes that need to be improved in the travel peak are solved by designing genetic algorithm.Finally,using the genetic algorithm as the solution algorithm under the scenic spot reception capacity,scenic spot heat,passenger flow satisfaction rate,public transport travel time,tourist preferences and other factors and constraint conditions comprehensive screening,get the passenger flow satisfaction rate of 0.0046≤ρ≤0.0058 of the bus route scheme.Designed 20 direct dredging lines and 6 transit dredging lines,bringing tourism income of 383,801.2 yuan per hour for tourists and the society during peak hours.The theory and method of dredging customized tourism bus route planning proposed by this research reasonably supplement the current customized tourism bus service.On the one hand,it adapts to and meets the needs of urban tourists,on the other hand,it plans a tourist route with high satisfaction for urban tourists,and arranges the vehicle route and tourism resources relatively optimal.This paper puts forward the theory and case for reference for the development and implementation of urban tourist bus.
