Crowdsourced Pavement Data: The Carbin App

In 2017, America’s roads received a D rating by the American Society of Civil Engineers. For cities and states to improve their grade, they must first be able to accurately measure the quality of their pavements. Unfortunately, this often proves expensive and challenging.

To address this problem, CSHub researchers have created Carbin, an app that directs users to their destination while measuring pavement quality and its effect on fuel consumption.

With every trip they take, Carbin users contribute to a growing public map of pavement and emissions data that can help to inform infrastructure repair and fight climate change. Carbin has already surveyed hundreds of thousands of lane miles around the globe in countries like Mexico, China, and the United States.

Learn more about the app and the research behind it in this article in The New York Times or in the topic summary and research brief below. You can download Carbin on Google Play or the App Store.
