美国正在遭受老化基础设施，赚取一个D + Grade全国范围在A-F规范中，美国土木工程师协会报告。为了更好地遵守这些结构，包括恶化的道路和桥梁，密苏里大学（MU）科学家开发了一个smartphone-based monitoring system.
智能手机用各种传感器包装，如相机，加速度计，陀螺和外部红外传感器。一旦传感器连接到智能手机，用户就可以在路上无线地将实时基础架构更新传输到数据库。
“Assessing roads, bridges, and airfields with affordable sensors, such as those found in smartphones, really works,” says Bill Buttlar, the Glen Barton chair of Flexible Pavement Technology. “With a smartphone, we can stitch together many inexpensive measurements to accurately assess things like the roughness or deterioration of a road surface. In a recent project sponsored by the Missouri Department of Transportation, we also showed that it can accurately assess the condition of airport runways and taxiways.”

The researchers believe the crowdsourcing-gathered data set will help create a clearer picture of road and bridge safety, thus facilitating more informed decisions.
“Many of the existing methods to monitor our civil infrastructure systems have technical issues and are not user-centered,” says Amir Alavi, assistant professor of civil and environmental engineering in the MU College of Engineering, with a courtesy appointment in the Department of Biomedical, Biological and Chemical Engineering.
Alavi explains the public desires a “smart, cost-effective, scalable, user-centered” approach, and with the advancements in mobile technology, people can join the effort to monitor civil infrastructure.
