Summary Information

This project evaluated work zone incident management systems designed to improve safety and incident response times during reconstruction at the "Big I" interchange in Albuquerque, New Mexico. A construction traffic management center (CTMC) was developed to monitor work zone traffic conditions, assess incidents, and dispatch police, wreckers, and on-site courtesy patrols.

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 incident response time was under eight minutes and no fatalities were reported.
