Video cameras play an important role in providing administrators of modern Transportation Management Systems with real-time information. Unlike other types of detectors and sensors—which only provide digital data—cameras provide real-time images of traffic situations, giving administrators a valuable tool for analyzing complicated traffic
patterns and making snap decisions.

A typical Transportation Management System requires installing many video cameras. For example, it is now commonplace to see cameras located at regular intervals along the roadside when traveling on the highway. However, the problem faced by system administrators is that most of the cameras could be located up to several miles from the Central Traffic Control Center. In fact, for this kind of video application, large systems with numerous cameras and “distributed” camera locations make the installation and management of video transmission more difficult and complicated than for other types of devices. It is fair to say that video transmission is the most important issue related to making large, distributed video camera systems a part of a Transportation Management System.

Two kinds of video transmission solution are used for most Traffic Monitor & Control systems. One is the traditional “CCTV system,” which uses optical fiber to extend the transmission distance of video signals. The other is “Video over IP system,” which uses an IP network to transmit video signals.
