The Influence Of Passenger's Travel Information Release On The Operation Of Taxi Transportation System

Taxi transportation is an important part of the urban comprehensive transportation system,which undertakes the special transportation task of ordinary residents compared with public transportation.With the maturity and promotion of real-time taxi software and vehicle navigation system,online taxi has developed rapidly and become a part closely related to people's life.The existing taxi Hailing software improves the problem of poor information communication,reduces the deadhead mileage of blind tour of taxi,and improves the operation efficiency of taxi system.However,new problems also arise,the taxi Hailing software releases too many passenger travel information,which makes it easy for drivers to over screen passengers that can bring high profits and "invisible rejection" for drivers Carrying creates convenient conditions,also affects the efficiency and fairness of taxi system.Therefore,from the perspective of passenger travel information release,this paper studies the impact of different release modes on the efficiency and fairness of taxi system,in order to get a more suitable information release mode for the current urban road traffic environment,to complete the optimized allocation of taxi resources,to promote the efficient and orderly development of taxi industry,and to provide information release research in the future taxi field theoretical support.The main contents of this paper are as follows:(1)A survey of the impact of taxi software on drivers and passengers was carried out.According to the degree of release of passenger travel information,the travel information were divided into no-release,full-release and half-release mode.Combined with the current situation,this paper analyzes the characteristics of the no-release mode and full-release mode,and speculates the possible characteristics of the half-release mode,so as to provide the basic concepts and theoretical basis for the carrying of the simulation system.(2)Based on the 7-node road network simulation,this paper studies the impact of the release of passenger travel information on the operation efficiency of taxi transportation system.Formulate the road network construction,passenger generation and exit,taxi and passenger matching,taxi driving rules,simulate the process of taxi search,matching,carrying,and delivery of passengers,analyze the impact of different information release levels on taxi empty rate,waiting time of passengers,number of passengers to be delivered,average income of drivers,and prove that the information release mode can effectively improve the operation efficiency of the system.(3)Based on the chessboard network,this paper studies the impact of the openness of passenger travel information on the fairness of the network taxi system.The concept of fairness is introduced and simulation rules are improved.By changing the compensation rate and information openness,the taxi resources are recombined.The Lorentz curve of spatial distribution of taxi resources,spatial Gini coefficient and other fairness evaluation indexes are added to describe the fairness of passenger travel in the system.(4)Based on the actual taxi traffic data,verify the scientificity and rationality of the half-release mode of passenger travel information.Taking Didi data of Haikou as an example,this paper introduces the concept of opportunity cost,and makes a comparative analysis of different information release modes by using a variety of evaluation parameters,demonstrating that the half-release mode of passenger travel information can significantly improve the operation efficiency and fairness of the system,which is of high practicability and promotion value.
