The goal of our study is to provide a flexible information delivery system concept that makes use of various contextual data around the users to determine target receivers of the information specific to a certain context. This paper focuses on an information delivery system concept that uses finer-grained location-based screening of target receivers by integrated use of ITS spots and the Geo-messaging enabler in cellular networks. The system takes information of user's transport mode (e.g., riding on a car, walking) as a part of user's contextual information by utilizing smartphone sensors. In this paper, we present the two solution architecture alternatives that we propose to fulfill the target system functionalities and the results of the verification experiment conducted by using a prototype system of the architecture.Improvement of information delivery systems in ITS is an important issue to provide more effective guidance and support to the drivers and passengers, and use of contextual information with improved granularity is beneficial to this end.
