Mertz’s smartphone-based road infrastructure inspection project examines ways a device as common as a smartphone can give municipalities a fast and inexpensive method for inspecting their roadways. In two basic steps, the technology collects images and then examines the data to identify areas that need care.”The work of Mertz is an ideal example of Traffic21’s vision of research, development and deployment,” said Stan Caldwell, executive director of Traffic21 and Technologies for Safe and Efficient Transportation (T-SET), a National University Transportation Center Stfunded by the U.S. Department of Transportation. Both organizations have supported Mertz’s research.
