In this work, to analyze a travel behavior by providing environmental information using ICT (Information and Communication Technology), we investigated the following issues. At first, we selected an information device and a method to provide environmental information efficiently by using web-based questionnaires. In addition, we analyzed the importance of environmental information in the selection of a transport route by using conjoint analysis. We developed a transport route guidance system that provided the duration, fare and amount of CO2 emission related to six transport routes from Hamamatsucho station to Tokyo Big Sight, and conducted a demonstration experiment providing transport information via mobile phones to actual respondents. As a result, it was confirmed that the respondents changed their travel behavior significantly by providing the transport information. The ratio of the transport route selected, based on the transportation image, was large without using the guidance system, and they tended to decide on their transport route based on the fare retrieved from the guidance system. It was suggested that an ICT service that includes environmental information would encourage transport users to choose a transport route in consideration of the environment, because 11% of the respondents selected their transport route by referring to environmental information.
