Thermal Imaging Solutions Mitigate Risks to Pedestrian Safety
According to data from the National Highway Traffic Safety Administration (NHTSA), more than 75% of automotive-related pedestrian fatalities in the U.S. in 2021 occurred at night. This value is hardly an outlier. Nighttime pedestrian fatalities in the U.S. increased at a rate of more than 3× that of comparative daytime incidents since 2010, per the Governors Highway Safety Association. TriEye’s detection and ranging platform delivers 2D and 3D SWIR images. The company
