Abstract | This research constructed the disaggregate modal choice model with four travel modes (bus, taxi, car and motorcycle) for work trips in Taichung area, Taiwan. Data were collected through a random work place interview of 500 respondents from Taichung City and its six neighboring villages. With the Logit Model, several alternative model specifications were tested, and the results of these tests were analyzed. The model specification considered to be the most satisfactory is based on on-vehicle travel time and out-of-pocket cost as generic variables. The socio-economic variables affecting the modal choice in Taichung area are: income, sex and travel distance. Prediction results in the calibration of the modal split model have 88 percent accuracy to forecast the actual choice. The time value of work trip in Taichung area is NT$ 68.8. It means that travellers are willing to pay NT$ 68.8 to save one hour or more of on-vehicle travel time when they used any of the four modes for work trips in this area. One important transportation problem identified after calibrating the modal split model is that most of trip-makers use private modes for their work trip. Focusing on this problem, the feasible policies: the bus exclusive contra-flow lane, increasing parking fee, area licensing scheme and combined two approaches were applied to forecast their impacts to the modal split behavior in the years 1996, 2001 and 2006. The results revealed that the efficiency of each policy is not sufficient enough to fully solve the problem. This is because the high growth rate of car users will not change in the future. Nevertheless, the possibility of diverting car and motorcycle riderships to bus riderships can be attained to some extent under the given assumptions. But it is important to note that combination of the two policies as applied here can provide a better or more efficient forecast. These forecasts could provide very useful guidelines in formulating other relevant policies for the existing transportation system in Taichung area. |
