Summary
This report evaluates the deployment and effectiveness of the Integrated Incident Management System (IIMS) in New York City, a project funded under the Federal Highway Administration’s Intelligent Transportation Systems (ITS) Public Safety Program. The primary research objective was to assess how IIMS, a real-time data exchange platform, improved incident management, inter-agency coordination, and emergency response capabilities across the five boroughs of New York. The system was designed to address the lack of interoperable communications among transportation, law enforcement, and emergency response agencies by enabling real-time sharing of incident data, GPS locations, and digital imagery. The evaluation, conducted by Science Applications International Corporation (SAIC), utilized a mixed-methods approach. Initially, the team attempted a comparative “before” and “after” analysis of incident metrics such as duration and response time. However, due to difficulties in establishing baseline data for the pre-IIMS era, the methodology shifted to focus on case studies, usage analysis, and stakeholder feedback. The evaluation examined specific incident types, including roadway damage, tractor-trailer accidents, debris spills, and fuel spills. Researchers analyzed IIMS-generated incident records, conducted focus groups with users, and reviewed system usage trends from 2004 to 2006. The assessment also included qualitative reviews of system deployment challenges and lessons learned regarding inter-agency collaboration and resource allocation. The findings indicate that IIMS was a successful deployment, having been mainstreamed into the operational IT infrastructure of the New York State Department of Transportation and New York City agencies. Quantitative analysis of roadway damage incidents demonstrated reduced incident durations and verification times. The system facilitated faster identification of required response assets, eliminating the need for supervisors to physically visit scenes for initial assessments. Additionally, IIMS improved incident documentation through centralized logging and archived digital records, which enhanced post-incident evaluation processes. The evaluation also identified potential benefits in improved mobility, reduced exposure of responders to hazardous conditions, and energy savings through more efficient incident clearance. Stakeholders reported that the system significantly improved inter-agency communication and coordination. The significance of this study lies in its demonstration of how integrated ITS technologies can overcome communication barriers in emergency response. The report concludes that IIMS provides a cost-effective, interoperable platform that enhances safety for both travelers and responders. Key lessons learned emphasize the importance of high-level management support, user involvement in system development, and gradual establishment of formal inter-agency agreements. The authors recommend that other jurisdictions consider similar deployments and suggest that future evaluations should leverage the richer data now available from mature system usage to quantify broader impacts on transportation performance and public safety.
