| Abstract | Induced traffic is defined as the potential trips that would be generated because of improvement on transportation service. However, it is difficult to identify induced traffic from the empirical evidence. There is yet no generally accepted methodology to derive the induced demand. In a typical appraisal of transpmiation demand forecast, the induced traffic is excluded or ignored because of simplification. Besides identifying the induced traffic due to improvement on transportation service in the past in Taiwan, this research presents the methodology for estimating the variation on transportation market resulted from the introduction of High Speed Rail. Reviewing the limited number of studies, the variables selected directly to reflect the induced demand by the new transportation system are socio-economic impetus and travel time saving. In this study, the socio-economic factor is included whereas the travel time saving factor not. The time saving benefit of the new mode will divert the trips from the existing modes that is reflected in the modal split model in this study. This study further analyzes the influence carried out from the diversion effect on the market instead of using saving time factor directly. The diversion effect to the superior new mode yields more space on the congested system and hence encourages original suppressed trips to recover. The latent trips are defined as another source of induced demand in this study. It is estimated that there will be 2.1 % of total market new induced results in the introduction of HSR in Taiwan in year 2003, the scheduled open year. However, the number of induced trips is different from case to case and with the higher figures in prior congestion areas. |
