| Outline of Final Research Achievements |
Recently, infrastructure monitoring in developing countries is not enough, though it becomes very important based on the development of social capital. In this study, we asked to collect road state data, especially road bump and hourly traffic link speed from GPS and acceleration data, for the person in developing countries by smartphones using crowdsourcing technology, such as outsourcing market place “Freelancer” and utilization of hub person in these countries. Finally, we collected approximately total 7,800km namely actual link based 800km driving data in short periods such as 1 month and a half based on the hub person method. This length means about 38% coverage toward 2,140km as a total road length in Dhaka metropolitan urban area. This result shows the possibility of collection of infrastructure monitoring data with their quality in short periods.
