An Analysis of the Impact of Activity Characteristics and Individual Characteristics on the Transport Mode Choice: A case Study of Budapest city, Hungary

Dealing with the present congestion and creating sustainable transport systems has been the greatest challenge of urban transport planning. As transportation activities affect environmental quality, knowledge, why travellers prefer specific modes can help a region do judicious transportation planning. The travellers' daily trip and mode choice process have mainly involved three types of choice: mode choice, time choice, and route choice. In this paper, we focus on studying the impact of the activity characteristics that include activity purpose and the characteristics of the individuals, such as gender, age and income, and average distance of the trip, on the transport mode choice for completing activities of travellers. The aim is to use statistical analysis to investigate the impact of these variables on transport mode choice applying the decision tree model, which provides a set of easy-to-interpret decision rules necessary to make appropriate decisions. The data processing in this study is based on actual observations of travel behaviour in Budapest. Our analysis's findings indicate that income, distance, and activity purpose are the most significant factors in the decisions related to mode choice. Also, this study provides promising insights for developing activity chain modelling.
