Intention of Travel Mode Transfer and Analysis of Influencing Factors: A Case Study in Lhasa

The number of private cars has increased rapidly in some small and medium-sized cities with low density road networks. The contradiction between supply and demand results in serious traffic congestion. Through a questionnaire survey of private car owners in the main urban area of Lhasa, car usage is analyzed. A multiple logit model is used to examine the influencing factors of travel mode transfer, especially parking fees and the ratio of travel time between bus and car. The result also shows the influence of other factors, including gender, age, level of income and education, occupation, number of school age children, and number of family cars. Trip characteristics such as shortest distance, frequency, and main trip purposes are studied, providing decision support for formulating effective transportation demand management (TDM) policies and traffic planning objectives. These objectives include encouraging residents to transfer from private cars to public transport, alleviating traffic congestion.
