Vision Systems Regulate Traffic, Improve Safety
On the roads at any given moment, there are traffic accidents, stopped vehicles, and drivers going the wrong way on one-way streets. All of these incidents adversely affect traffic flow and lead to congestion, delays, and, sometimes even secondary accidents. These realities have given rise to the intelligent transportation system (ITS), which involves a host of communication, control, sensing, and imaging technologies working in tandem to improve efficiency and safety.
