Study On The Route Choice Behavior Of Travelers Based On Prospect Theory

With the acceleration of urbanization,the number of motor vehicles is increasing year by year,and the problem of urban traffic congestion is becoming increasingly seriously.Although currently adopting a series of management measures such as optimizing the structure of the urban road network,adjusting the urban spatial layout,and strengthening the intelligent control of traffic operations,to a certain extent,it has alleviated the urban traffic problem,but the solution to the problem still needs to find a more effective way And methods.This article starts from the perspective of participants in transportation,based on the perspective theory,comprehensively considers route travel time,traffic light waiting time,and travel reliability requirements to set route reference points,and constructs a value function and a decision weight function.To derive the foreground value of the alternative route.Taking Qingdao as an example,it distinguishes between three working days,weekends,and holidays,and establishes a model for the decision-making behavior of alternative routes between target ODs,and analyzes the traveler’s travel behavior and its influencing factors.Finally,a questionnaire is used.The data and taxi GPS data are used to validate the results of the model and provide an effective supplement to the method for solving urban traffic problems.The main research contents include:First,pre-process the acquired data.Road network operation data and GPS data may cause data loss,duplication,etc.due to the inconsistent signal strength of the terminal,delay in acquisition time,or the effects of severe weather.The collected data is slightly different from the actual situation.Data compression is used to screen the data And pre-process the road network operation data with interpolation method and GPS data with direct projection algorithm.Second,consider the travel time of the traveler,the waiting time for traffic lights and other factors to set the reference point of the model,derive the value function function,and calculate the prospect value of the alternative path by constructing the path selection model.The model is applied to two alternative paths of target OD from working days,weekends and holidays,and the validity of the model is verified using questionnaire data.Third,consider the travel reliability needs of travelers,set the model reference point,construct a value function and a decision weight function,and estimate the prospect value of the alternative path.The model application analysis was performed on the two alternative paths between the target ODs from working days,weekends,and holidays,and finally the validity of the model was verified using Qingdao taxi GPS data.Finally,the main content of the paper is summarized,existing problems are sorted out,and further research directions are proposed.
