Summary

This guidance document, produced by the Federal Highway Administration (FHWA), addresses the intersection of Integrated Corridor Management (ICM), Decision Support Systems (DSS), and business rules. The research is motivated by the need to clarify how these three components interact to enhance multimodal transportation management. ICM is defined as the operational coordination of multiple transportation networks and institutions within a specific corridor to improve accessibility and efficiency. The document aims to provide practitioners, managers, and designers with a fundamental understanding of how DSS and business rules function within ICM, particularly given the lack of detailed specifications for business rules in the transportation domain. The methodology involves a comprehensive review of existing literature, case studies, and operational data from fully implemented ICM demonstration sites, specifically Dallas (US-75) and San Diego (I-15). The authors analyze the development of DSS in these sites, examining how users interact, communicate, and coordinate across agencies. The document utilizes analogies, such as chess and hospital operating rooms, to explain the relationship between the corridor (context), agencies (actors), business rules (constraints), and DSS (strategy). It also reviews the history of DSS, which consists of expert rules, prediction models, and evaluation components, and outlines the institutional frameworks required for interagency cooperation. Key findings highlight that successful ICM relies on interagency agreements and shared real-time data to manage non-recurring events like incidents and special events. The document identifies that business rules are predefined permissions and constraints that bind participating agencies, ensuring that DSS recommendations align with agreed-upon policies. Case studies from Dallas and San Diego reveal that effective implementation requires overcoming institutional differences, establishing clear communication protocols, and developing robust interagency agreements. The analysis shows that DSS helps overcome human decision-making biases by providing data-driven recommendations for traffic operations, such as adjusting signal timing or diverting traffic to alternative modes. The document also notes common challenges, including staffing limitations, budget constraints, and the need for cooperative working relationships among federal, state, and local agencies. The significance of this work lies in providing a structured framework for deploying DSS within ICM initiatives. By clarifying the role of business rules, the document helps agencies avoid operational redundancies and improve corridor performance. It offers practical guidance on developing concepts of operations, forming interagency agreements, and leveraging technology for proactive traffic management. The findings suggest that integrating DSS with clear business rules enables agencies to predict and mitigate traffic problems before they occur, thereby enhancing safety and mobility. This guidance supports the broader goal of the FHWA’s ICM Initiative by promoting standardized approaches to multimodal transportation management and interagency collaboration.

Key finding

Business rules serve as the necessary inter-agency agreements that constrain and guide decision support systems to ensure coordinated, multi-jurisdictional operations within integrated corridor management.
