Most commuters select the travel pattern which derives the maximized utility subject to time and money budget constraints, scheduling convenience and parent responsibility in the busy city life. In other words, the commute tour may be divided into several trips. In the past decades, some activity-based studies detected that a larger number of stops will have a higher degree of separation of activities. These activities are associated with a higher utility. In recent years, some studies start to investigate the relationship between stop-making behavior and mode choice of individuals.
In this study, we consider the impacts of commute stop-making as well as commute travel time reliability on commute mode choice. In Taiwan, we would like to figure out following points based on the empirical analysis, as (1) the relationship between commuter’s stop-making behavior and his/her background; (2) causal relationship between stop-making and mode choice; (3) how could inertia affect the mode choice decision; (4) is lower public mode reliability causing a higher private mode usage. We adopted a survey approach to collect information from Hsinchu Science Park commuters. The complete sample consists of 401 individuals and it uses binary logit framework method to estimate. Furthermore, the commercial software package LIMDEP was used to calibrate parameters.
The results are: (1) Commute stop-making does have an effect on mode choice. (2) Travel time reliability is an important variable in commute mode choice decisions. (3) Household structure significantly influences the activity and travel patterns of commuters. (4) Furthermore, it is hard to change the habit of commute mode, especially from private to public mode. |
