Implementation of information collecting tools using mobile terminals useful for efficient infrastructure maintenance

While the aging of social infrastructure in Japan is advancing, the number of technical experts responsible for infrastructure management has drastically decreased, which has become the major problem to solve social infrastructure aging problems. In order to build a social infrastructure management system with the collaboration from citizens, a 'citizens' participation with ICT technology' was constructed in this research to make it possible for citizens to report the malfunction of social infrastructure, including the situation, the position and the details to the administration of the government. Then a social experiment utilising this system was conducted in two different municipalities with the participation of citizens. Finally, the effectiveness of the system and the problems for dissemination were verified through a questionnaire survey.
