Investigate the travel routes and travel mode choices of residents from Suzhou to Shanghai,consider different impact variables in the survey,and divide their travel lines into two travel days on weekdays due to commuting to Shanghai, and free travel to Shanghai on weekdays.The data of the survey were analyzed and analyzed,and the parameters of the established Nested Logit model were calibrated by ST AT A software.The selection model and time value of the travel route and travel mode of residents under different scenarios and different influence variables were obtained Analyze.展开更多
