The focus of this study is to detect sinkhole hazards using airborne light detection and ranging (LiDAR) data. The premise is sinkholes, particularly those close to transportation infrastructure assets, could cause substantial damages to infrastructure assets, and therefore, being able to accurately and rapidly detect them is essential. However, it is expensive, time-consuming, labor-intensive, and unsafe to survey sinkholes using conventional ground observation methods. This research project was focused on developing accurate and rapid airborne LiDAR-based sinkhole detection and mapping methods, and transfer the technologies to transportation engineers for implementation and workforce development. The project team also identified best practices …

In July of 2017, the Boston Globe published an article titled “Driving Through These Towns in Mass.? Watch Your Speed” [1] that among other elements, included a series of maps and a brief summary identifying Massachusetts municipalities that had the most traffic violations issued between 2010 and 2016. The article stated that the Massachusetts State Police issued the most citations of any police agency in the state, and that many citations were given along major highways, especially Interstate 90 and major highways and routes that intersect it, such as Interstate 84 and Route 20. Despite the public attention-grabbing nature of …
