Integrated Corridor Management Initiative

Slide 1. Integrated Corridor Management Initiative

ITS JPO Lead: Mike Freitas
Technical Lead: John Harding, Office of Transportation Management

Slide 2. Background

  • Currently surface transportation systems are made up of several independent networks
    • Freeways, including managed lanes
    • Arterials
    • Bus Routes
    • Rail Transit
  • In reality each of these networks is made up of high volume links
  • These parallel network links overlay to form transportation corridors
  • Metropolitan areas contain several major corridors

Slide 3. Opportunity

  • Efforts to date to "reduce congestion" have focused on optimization of individual networks
  • No capability to respond to demand from other networks
  • Integration across networks is critical in these high demand corridors
  • Corridors offer an opportunity to operate and optimize the entire system as opposed to the individual networks

Slide 4. Integrated Corridor Management Systems: Examples

  • Traffic signal systems that respond to large diversions of traffic from clogged freeways
  • Demand responsive ramp metering systems integrated with local traffic signals
  • Adaptive bus prioritization that responds to increased bus traffic during special events
  • Traveler information systems that estimate and predict congestion over time and balance demand on networks

Slide 5. Goals

  • Provide guidance to assist agencies in implementing Integrated Corridor Operations
  • Create supporting analysis tools, approaches, and technical standards
  • Demonstrate the value of Integrated Corridor Management

Slide 6. Milestone/End Product

  • Widespread Integrated Corridor Operations, resulting in:
    • Efficient use of available network capacity
    • Reduced congestion and delays
    • More reliable travel

Slide 8: Program Plan/Approach

  • The Initiative consists of four phases
    • Phase 1: Foundational Research
    • Phase 2: Operations and Systems Development
    • Phase 3: Model Deployment
    • Phase 4: Knowledge and Technology Transfer
  • Duration of Initiative
    • FY04–FY10

Slide 9. Phase 1: Foundational Research

  • Goal 1: Engage Multimodal Stakeholder Working Group
    • Action
      • Candidate Model Deployment Sites will form core group
  • Goal 2: Foundational Integration Studies
    • Actions
      • Define Corridor Concept of Operations
      • Document Successful Local Integration Efforts
      • Identify Corridor Types and Operational Approaches
      • Identify Operational Strategies and Analysis Tools
      • Identify Functional Requirements
  • Decision Point #1 – August 2005
    • Did we identify sufficient integration issues?
    • Are the issues workable?

Slide 10. Phase 2: Operations and Systems Development

  • Goal 1:Organizational Integration
    • Action
      • Develop cross network management systems that support distribution of responsibilities and sharing of control
  • Goal 2: Operational Integration
    • Action
      • Develop cross network operational strategies and analysis tools
  • Goal 3: Technical Integration
    • Action
      • Develop interfaces and integrated procedure to facilitate operational strategies, i.e. device-to-device integration
  • Decision Point #2 – Sept. 2007
    • Do we have the knowledge and capabilities to support an effective model deployment?

Slide 11. Phase 3: Model Deployment

  • Goal 1: Pre-Model Deployment Activity
    • Actions
      • Pre-Model Deployment Workshop
        • Prep for Candidate Sites
      • Candidate Model Deployment Sites Selection
        • Form core of stakeholder group
        • Detailed examination of specific issues and problems
  • Goal 2: Model Deployment
    • Actions
      • Site selection and Implementation
      • Apply integration techniques in real world setting
      • Model Deployment Evaluation

Slide 12. Phase 4: Knowledge and Technology Transfer

  • Goal 1: Pre-Model Deployment Knowledge and Technology Transfer
    • Action
      • Support Candidate Sites preparing for Model Deployment
  • Goal 2: Integrated Corridor Management Outreach, and Knowledge and Technology Transfer
    • Action
      • Produce detailed Integrated Corridor Management implementation guidance to ensure areas with interest in deployment have the information and technology they need
      • Includes management systems, operational strategies, tools, technology transfer, standards, and training

Slide 13. Summary

  • Congestion is complex
  • Corridor Management can make a difference
  • Significant integration challenges must be addressed
  • Opportunity to enhance our capabilities and improve performance
