New Orleans Traffic CamerasAt the conclusion of the New Orleans I-10 project LADOTD determined they wished to convert the 8 portable cameras to permanent pole-mount cameras. RTI was contracted to install wireless communications and provide a web site for the images to be seen by the traveling public from the permanent mount cameras along I-10 and I-610. LADOTD took the cameras off line in the fall of 2009. Capitol Beltway Enhanced Variable Speed Limit SystemVDOT contracted RTI to provide software, hardware, communications and services to control speed limits on the Washington D.C.
