1 Chapter 1 - Getting Started: Using the Guidance Document Introduction Most jurisdictions have recognized the importance of managing their systems through interjurisdictional coordination with emergency responders, incident response, transit, mobility services, and maintenance and construction management as well as timely notification to the public. Many agencies use traffic operations strategies for the reduction of recurring and nonrecurring congestion. Many jurisdictions have implemented a variety of strategies for maximizing flow on facilities by using all available pavement, transportation services, and managing their facilities using new technologies and better operations techniques. However, actively integrating strategies such as transit rerouting, mobility-on-demand services, multimodal trip- making, arterial coordination, detour planning, and managing lanes in real-time requires planning and coordination among many stakeholders. Pulling this all together through integrated corridor management (ICM) is essential to successful transportation system management. Additionally, new challenges in staffing and funding are present due to the new institutional, technical, and operational integration required for ICM. What is ICM? Integrated corridor management (ICM) is an approach to improving transportation that considers all elements in a corridor, including highways, arterial roads, and transit systems. ICM takes an integrated, multimodal/multiagency approach to congestion management. ICM uses technology and operational strategies as tools for transportation operators to address recurring and nonrecurring congestion and optimizes performance of the transportation infrastructure. Rather than address the shortcomings of the separate roadways and modes in isolation, ICM treats the individual transportation components (highways and roads, transit, parking lots, bicycle and pedestrian trails, etc.) as elements of an interrelated transportation corridor. ICM also promotes interjurisdictional coordination and the use of a broad toolbox of transportation system management and operations (TSMO) strategies to optimally detect, monitor, and respond to events and changing conditions. General benefits include improved mobility, reliability, and safety, and reductions in fuel consumption and emissions. By optimizing the use of existing infrastructure assets through coordinated transportation management techniques, transportation investments can go farther. There are many corridors in the country with underused capacity (in the form of arterials, freeway travel lanes, and parallel transit capacity – e.g., bus, rail, bus rapid transit, etc.) that could benefit from ICM. The maturation of intelligent transportation system (ITS) technologies, availability of supporting data, and emerging multiagency institutional frameworks make ICM practical and feasible. There are a significant number of freeways, arterial, and transit optimization strategies that are already in widespread use across the United States. Many of these strategies are managed locally by individual agencies, often independently. Even those managed regionally are sometimes managed in isolation (asset-by-asset), rather than in an integrated fashion across a transportation corridor. Why consider ICM? Currently, many agencies operate their transportation networks well, but do not consider the overall operation of a corridor or region to improve the throughput of travelers through the corridor. ICM focuses on the operational, institutional, and technical coordination of multiple transportation networks and cross- network connections comprising a corridor. Moreover, ICM can encompass several activities that address the concerns and needs of agencies in a region (e.g., integrated policy among stakeholders, communications

2 among network operators and stakeholders, improving the efficiency of cross-network junctions and interfaces, real-time traffic and transit monitoring, real-time information distribution, congestion management, incident management, public awareness programs, and transportation pricing and payment). According to the United States Department of Transportation (USDOT), “The vision of Integrated Corridor Management (ICM) is that transportation networks will realize significant improvements in the efficient movement of people and goods through institutional collaboration and aggressive, proactive integration of existing infrastructure along major corridors. Through an ICM approach, transportation professionals manage the corridor as a multimodal system and make operational decisions for the benefit of the corridor.” Who should use this Guidebook? The intended audience of this document is public agency staff and consultants involved in planning, designing, implementing, operating, managing, and maintaining ICM systems to improve the operations of their transportation networks by using a multiagency, multimodal approach. This document should help readers to appreciate how ICM planning fits into the current planning process and learn key lessons from other metropolitan areas who have planned and, in some cases, implemented ICM systems. Readers are assumed to have a general awareness of ITS technologies and transportation management principles. How should this Guidebook be used? This guidebook provides an overview of current recommended practices and outlines critical components for the planning, design and development, and operations and maintenance of an ICM system. It was written and organized to describe the overarching planning process at the various systems engineering stages of a technology deployment project. The study team collected the information in this report through literature searches on existing ICM research, deployments, planning grants, the tools used in the development of ICM in the transportation industry, and other resources for transportation agencies (e.g., the Federal Highway Administration [FHWA] ITS Program). The remaining chapters in this document are summarized in Table 1. Table 1. Where to Find ICM Information in this Guidebook Desired Information Guidebook Section • Definition of ICM • Overview of the approach in planning for ICM Chapter 2 – Overview of ICM • Assessment process to determine the utility of ICM to address the agency’s issues Chapter 3 – Pre-Assessing ICM • Planning process for ICM • Understanding how ICM fits into the systems engineering process Chapter 4 – Planning for ICM • Process for developing the technical components of an ICM system • The development processes to consider when developing an ICM system, including identifying system gaps Chapter 5 – Planning for the Technical Integration of ICM • Operational planning needed for ICM operations • Understanding needs for ongoing funding for operations & maintenance of the ICM program Chapter 6 – Planning for Operations and Maintenance of ICM

3 How was this Guidebook developed? The information and recommendations presented within this guidebook were developed through the National Cooperative Highway Research Program (NCHRP) Project No. 03-131. A literature review and stakeholder surveys and interviews were used to identify issues, needs, and best practices for ICM planning, development, deployment, and operations and maintenance. Research Objectives The objective of this research was to develop guidance for agencies planning and implementing multimodal, integrated corridor (or area) management, while featuring multiple real-world examples drawn from a variety of contexts and an appropriate range of agency capabilities. It endeavors to address the topic areas listed in Table 2, which also provides the Guidebook chapter that discusses each topic. Table 2. Topic Areas and Corresponding Guidebook Chapters # Topic Areas Guidebook Chapter 1 Defining the purpose and need of the integrated traffic management approach. Chapter 2, Chapter 3 2 Demonstrating the value of the integrated approach to agency administrators and policy makers (including alignment with agency directions in a broader geographical area). Chapter 2, Chapter 3 3 Identifying and engaging needed partner agencies and defining their respective roles. Chapter 3 4 Deciding which scenarios will be cooperatively managed (e.g., crashes, special events, evacuation, adverse weather). Chapter 4 5 Determining viable strategies for managing traffic during those scenarios, including multimodal approaches. Chapter 4 6 Developing memoranda of understanding or other policies (internal and cross-agency) to support the traffic management system(s) and facilitate those strategies.
