US 2003/0201907 A1 · Automatic gate control system for freeway interchanges

Abstract

A freeway interchange traffic rerouting control system allows individual ones of the gates and signs to be operated from a workstation connected via the Internet to a web server and communications server that control spread spectrum radio transceivers. A system operator logs onto the Internet, proceeds to the interchange URL where a control panel and video screen appear. Signals may be sent from the workstation to a web server to operate the gates and to turn on advanced warning signs. Video feeds from strategically located cameras allow for viewing traffic activity at the intersection at the remote workstation. Provision is also made for detecting instances of violations whereby an alarm is given and the video detailing the violation is captured for analysis.
