A new technique to identify deteriorating infrastructure using satellite data

By Michael Brenneis With budgets that tend to favor new construction, many DOTs are finding it necessary to prioritize the most urgent repairs. But infrastructure decay is not always easily visible. And deferred or inadequate maintenance may occasionally have catastrophic consequences for U.S.

Reducing air pollution by targeting the most egregious emitters

By Bill Holloway New infrared cameras can identify various tailpipe emissions in real time from vehicles passing at highway speeds. While there are other remote sensing technologies that allow the infrared analysis of emissions from cars on the road, these normally require lower speeds, a single
