Finally – VIDS for Span-wired Signal Installations

Video detection systems (VIDS) are considered to be the smartest choice for detecting vehicles approaching signalized intersections. The VIDS typically have mast arm poles and the mounting platform provides a stable view and optimum location for positioning the camera sensor. However, traffic signals in most of the country are typically constructed with span-wire instead of the more expensive mast arm poles. Until now, the drawbacks for using VIDS at span-wired signals outweighed the benefits. This article presents the benefits of VIDS, which are: (1) a lower lifecyle cost; (2) the ability to gather more information; (3) the capability to redefine and add detection zones at will; (4) the ability to remotely view traffic conditions from the traffic manager’s desk; (5) the ability to remotely perform some maintenance from the traffic technician’s desk; (6) the avoidance of danger-filled and congestion-causing lane-blocking construction; (7) the ability to differentiate between bicycles and vehicles in the same processing unit; and (8) the ability via software updating to incorporate improved detection algorithms over time.
