The Need for Speed: Why Comms Bandwidth is in Demand

This article explains general issues surrounding the burdens placed on bandwidth by intelligent transportation systems (ITS) architectures. Closed circuit television (CCTV), video detection sensors (VIDS), dynamic message signs (DMS, HAZMAT sensors, and roadway weather information sensors (RWIS) are some of the systems mentioned that add a burden to bandwidth. While this need has been known since the 1990s, the article explains that these plans have become obsolete due to the sheer number of video surveillance cameras and that their footage now needs to be accessible by the public. It also notes the role the ITS will play in developing homeland security organizations worldwide. These organizations often demand higher visual clarity for identification purposes. The author warns of problems with wireless networks for these applications and provides suggestions as an agency can best modify their bandwidth plans to accommodate for the heavier traffic that is anticipated.
