Reducing Traffic with Computer Vision

How Transport for Cairo is Improving Commuting for Millions with Computer Vision Reducing traffic in well-planned cities where bus routes are well-mapped, subways are running on a predictable cadence, and lanes are well-marked is a significant undertaking. Now consider improving traffic without predictable routes, maps, and regular modes of transit.
