In Albuquerque, New Mexico, work zone surveillance and response at the "Big I" Interchange reduced average clearance time by 44 percent.
Work zone surveillance was achieved through closed circuit television cameras (CCTV), broadband wireless communications, and directional antennas. Motorists approaching the interchange of I-25 and I-40 were made aware of traffic conditions (lanes affected) via information displayed on dynamic message signs (DMS), and through strategic deployment of portable changeable message signs (CMS). In addition, pre-trip traffic information was updated every three minutes on the "BIG I" Internet web-site.
After approximately one year of operations, the average clearance time on the "BIG I" was 20 minutes faster than the historical average clearance time of 45 minutes.
