In this study, wireless monitoring systems were developed as an element technology of next-generation asset management. Prototypes which have features of processed data collection using road-to-vehicle communications, original data collection using wireless communications, easily-exchangeable sensor and autonomous driving based on battery, etc. were produced. By applying prototypes to long-term monitoring of actual civil structures, the following results were obtained. In long-term monitoring for approximately 10 months, prototypes have some troubles however measurement of acceleration response and collection of original data based on wireless communications are possible. Reductions of the battery voltage in the actual environment are larger than the predicted value, and it requires attention to the battery capacity.
