In 1995, the U.S. Congress directed the Federal Highway Administration to describe how and when it would design, deploy, and maintain a commercial vehicle information system network (CVISN). The CVISN conceptualization focused on inspections and safety ratings, out-of-service orders and registration denials, objectives and constraints, and data collection and use. The three CVISN operation capabilities are safety information exchange, credentials administration, and electronic screening. A Level 1 implementation results in basic operation functionality in these three functional areas. A Level 2 implementation results in advanced operation functionality in these three areas. Using data collected by commercial vehicle inspection officers in Arizona, this study evaluates the integration of CVISN at the Nogales port of entry and identifies opportunities for improving operation effectiveness in the future. The study analyzed commercial vehicle port entries and clearance rates from 2005 to 2007 with CVISN. The results indicate that the cost efficiencies of the ports inspection booths could potentially be improved by roughly 30 percent under the current conditions at the site. |
