Two- and three-way camera systems are among the most commonly used traffic cameras.

In most cases, the cameras provide two different cameras to track traffic, providing data that can help local governments better plan for future traffic flow.

However, in many areas of the United States, these cameras aren’t as effective as two-way cameras, which have two cameras and a system to automatically send data back to a central location.

These cameras can provide valuable data that helps local governments plan ahead for traffic flows.
