Guidance for Planning and Implementing Multimodal, Integrated Corridor Management

  Project Data
Funds: $500,000
Contract Time: 18 months
Staff Responsibility: B. Ray Derr



The objective of this research is to develop guidance for agencies planning and implementing multimodal, integrated corridor (or area) management. The guidance should feature multiple real-world examples drawn from a variety of contexts and an appropriate range of agency capabilities. At a minimum, the guidance should address (though not necessarily in this order) the following:

1.      Defining the purpose and need of the integrated traffic management approach.

2.      Demonstrating the value of the integrated approach to agency administrators and policy makers (including alignment with agency directions in a broader geographical area).

3.      Identifying and engaging needed partner agencies and defining their respective roles.

4.      Deciding which scenarios will be cooperatively managed (e.g., crashes, special events, evacuation, adverse weather).

5.      Determining viable strategies for managing traffic during those scenarios, including multimodal approaches.

6.      Developing memoranda of understanding or other policies (internal and cross-agency) to support the traffic management system(s) and facilitate those strategies.

7.      Identifying decision support tools, ranging from simple heuristics to complex approaches with embedded simulation models (the typical daily operation should be included as an option).

8.      Setting performance metrics and targets.

9.      Identifying data and information that should be shared between agencies and viable architectures for the sharing.

10.  Inventorying the ICM infrastructure (e.g., traffic management field and central elements, communications, software) and identifying needed improvements.

11.  Identifying ways to report the performance of the traffic management system(s) (e.g., dashboards) and measure (or estimate) the benefits of the actions taken.

12.  Developing and implementing a deployment plan for the traffic management system(s).

13.  Developing an appropriate staffing model, including hiring, training, and outsourcing.

14.  Developing a plan for ICM maintenance, sustainability, and continuous improvement.


The guidance is expected to draw extensively from existing publications and ongoing research and deployment efforts. Proposals should identify the key references and related efforts. The project oversight panel expects that this project will, in particular, add new knowledge to the functions listed above as #4, 7, 9, and 14. Proposers should present their initial thoughts on what this new knowledge would encompass and how the knowledge would be generated.


The contract is under negotiation.




Many jurisdictions have implemented a variety of strategies for managing and maximizing flow on their roads using new technologies and better techniques. Most recognize the importance of interjurisdictional coordination with emergency responders, maintenance and incident response, and construction management, as well as providing timely notification to the public in managing their systems. Monitoring traffic operations through traffic management centers with reliable detection and surveillance and available deployment strategies (e.g., incident response) advances active approaches to reducing both recurrent and nonrecurrent congestion.


Pulling this all together through Integrated Corridor Management (ICM) is essential to successful system management. ICM actively integrates the separate strategies (e.g., ramp metering, arterial coordination, detour planning, traveler information, managed lanes) in a real-time manner, and introduces new challenges in traffic management center staffing and funding.


A recent NCHRP Domestic Scan report, Advances in Strategies for Implementing Integrated Corridor Management (http://www.trb.org/Main/Blurbs/172735.aspx), reviews various ICM deployments, including an analysis of real-time models for planning and operations for ICM, and the implementation of decision support systems (DSS) for ICM. As part of the final report, an ICM Capability Maturity Model was developed which covers six process areas for ICM, including DSS.


The FHWA publication, Coordinated Freeway and Arterial Operations Handbook (https://www.fhwa.dot.gov/publications/research/operations/its/06095/), presents a useful framework for considering improvements in a corridor; however lessons learned since its publication and current capabilities for data sharing and management have advanced the state of knowledge and should be captured. State, local, and regional transportation agencies that are considering ICM efforts would benefit from up-to-date guidance on their planning and implementation that helps staff to work through the many issues that should be considered.
