Travel Decision Model of Heterogeneous Commuters under Uncertain Environment

摘要

In order to better describe the commuter's travel decision-making behavior under different travel environment, heterogeneous commuters and types are defined, and the commuters are divided into three types, including conservative type, neutral type and adventure type, respectively, analysis on the travel environment supply and the travel environment demand. Suppose the travel demand obeys the gamma distribution and the capacity obeys the beta distribution, and the travel time function of different commuter type is deduced, the travel decision model based on the cumulative foreground theory is established. Analyze the example results, compared with the fluctuation of travel demand, the degradation of traffic capacity has a more significant impact on travel decision-making behavior; and different types of commuters cause different disturbances to travel decision-making behavior.
