Intelligent transportation systems in work zones : a case study : work zone traffic and incident management system : keeping traffic moving during reconstruction of the Big I, a major interstate-interstate interchange in Albuquerque.

This case study is one in a series of documents that examines the use of Intelligent Transportation Systems (ITS) in work zones. This case study reflects information gathered in interviews with key personnel on the Big I interstate-interstate interchange reconstruction project in Albuquerque, New Mexico, as well as information and photographs obtained during a site visit. The use of ITS for the Big I proved to be very successful in mitigating the effects of construction on traffic mobility and safety. The New Mexico State Highway and Transportation Department plan called for the use of ITS during construction, and also allowed some of the system components to be made a permanent part of the freeway management system for the Big I. This case study provides information on: project and system background; system design, selection and implementation; system description and operations; results, including system performance, system evaluation, benefits/impacts, public reception/reaction to the system, and obstacles encountered and lessons learned; and conclusions.
