摘要

"Intelligent Transportation Systems (ITS) encompass a broad range of wireless and wireline communications-based information and electronics technologies. When integrated into the transportation system's infrastructure, and in vehicles themselves, these technologies relieve congestion, improve safety and enhance American productivity." USDOT website. Over the past 10 years, technological advancements in ITS have been plentiful. One thing, however, has been consistent: from the introduction of closed-loop traffic-management systems to the expansion of full-blown ITS infrastructure, communications has always provided the backbone of these systems. Mission-critical data is typically collected from a variety of devices, such as detectors (loops, video, radar), traffic controllers, PTZ cameras etc. This data is then used to implement efficient timing plans, operate variable message signs (VMS), and control flashing beacons in order to appropriately manage traffic flow and traffic incidents.
