The new system will use cameras, sensors and artificial intelligence to better estimate traffic volumes, arrivals on red and side-street delays. But she says privacy issues are not a concern. "Maybe you can make out a make and a color, definitely not a model, you're not going to tell license plate information, driver, or any of that information," she said.
