운전자 경로전환 의사결정에 작용하는 정보이용매체에 관한 연구

The key success factors of ATIS depend not only on the good hardware design but on the recognition of drivers' heterogeneity of preference about traffic information. Such being the case, the preference characteristics of traffic information and human factor aspect characteristics should be carefully investigated and proper traffic information strategy should be arranged based on such characteristics. As a basic study of such kind, this paper tried to investigate media used for traffic information provision media. An actual survey was conducted at the tollgate side and the results showed that drivers relied more on the traffic information provided than on his or her previously acquired experience. Additionally, they used traffic information broadcasting radio during the high peak period like Chooseok whereas they normally followed VMS based traffic information during weekend congestion period.
