||Many cities have developed e-bus service actively in recent years. Taipei city also started it in 2004, and completed the third stage of this project which includes four stages. The whole project is expected to be completed at the end of 2009. For Taipei City government, when developing this new infrastructure, e-bus system, the key issue is to understand the intension to use of the public.
This study aims to integrated relative advantages, information quality into the Technology Acceptance Model (TAM) suggested by Davis et al. (1989), to examine the impacts of the relative advantages (cost, convenience, and security), and information quality (precision, currency, and completeness) on the perceived usefulness and perceived ease of use, and then their impacts on the intention to use.
The on-line questionnaires were placed on the webpage of the e-bus portal site after got approval from Taipei government, targeting populations who inquiring information on the system joining this investigation. Four hundred and five questionnaires were collected. Therefore, this research retrieves the effective result in response from group of people who uses the e-bus information system.
By employing linear structural equation modeling (SEM) for analyzing, the results indicate that “perceived usefulness” and “perceived ease of use” have significantly positive effect on “intension to use”. “Perceived ease of use” has significantly positive effect on “perceived usefulness”. The publics’ perceived usefulness of Taipei e- bus mainly depends on convenience of use, and precision and completeness of information. That is, when users perceived the convenience as well as precision and completeness information provided by this service system, they intend to use this system. The convenience, precision and completeness information provided by Taipei e-bus system, have significantly positive effect on perceived usefulness and then affect the intention to use.
