1. Integrated Corridor Management (ICM)
Brian P. Cronin, P.E.

2. What is ICM?
ICM is a promising tool in the congestion management toolbox that combines advanced technologies and innovative practices.
ICM is the proactive, joint, multimodal management of transportation infrastructure assets along a corridor by transportation system operators and managers.
ICM seeks to optimize the use of existing infrastructure assets, making transportation investments go farther.
With ICM, the corridor is managed as a system—rather than the more traditional approach of managing individual assets.
Key Messages:
ICM is the next step in congestion management: It optimizes existing transportation infrastructure along a corridor, making transportation investments go farther.
With ICM, transportation managers and operators seek to leverage under-utilized corridor capacity such as parallel routes, transit services, and single occupant vehicles to help manage congestion.
Better “visibility” across the corridor’s transportation network gives transportation managers and operators more choices for managing travel demand and can help to provide more actionable traveler information. For example, ICM will enable transportation managers to better manage congestion-triggering events by allowing them to redistribute spikes in travel demand across the entire corridor network.
ICM is the proactive, joint, multimodal management of transportation infrastructure assets along a corridor by transportation system operators and managers.
Transportation system operators and managers accomplish ICM through the combined application of advanced technologies and innovative practices.
The information and choice that ICM will afford will empower travelers, improve travel time reliability and help to manage congestion.
In short, ICM will help to:
Manage Traffic Congestion
Increase Travel Time Reliability
Empower Travelers

3. Example ICM Corridor Local Jurisdiction 1 — Traffic Signal System
Regional Rail Agency — Train Management System
State DOT — Freeway Management System
Key Messages:
This is a totally fictional, generic corridor designed to illustrate ICM.
In a future ICM corridor:
Drivers can receive actionable information that allows them to dynamically shift to alternate routes and modes of transportation (such as transit), even during a trip, in response to changing traffic conditions. Transit users will be able to more reliably plan their transit trips.
For example, a driver sitting in congestion could obtain actionable information that could enable them to make an alternative transportation choice such as a nearby transit facility’s location, timing and parking availability.
A transit user could be informed in advance not only of a delay on their transit route but of estimated travel times and alternate transit options that could more reliably deliver them to their destination under current conditions.

An ICMS is the set of procedures, processes, and information systems that
support transportation system managers in making coordinated decisions involving the
optimal performance of all transportation networks in a corridor.

5. ICMS Context
“ICM is about management of a corridor. Management implies more than monitoring. Management implies planning for, and responding to what is happening.”
Operational Objectives – Provide the Tools To:
Optimize performance at a corridor level
Improve utilization of existing infrastructure
Reduce travel delays
Achieve load balancing across the networks
Facilitate mode shifts
Facilitate route shifts
Facilitate departure/arrival shifts
Respond to events with coordinated multi-agency actions

8. ICM Pioneer Site Corridor Assets
Key Messages:
Consider highlighting any interesting or distinctive aspects of each of the Pioneer Site locations (maybe from the trivia quiz from the Pioneer Sites Kickoff Workshop) to help audience members connect with these sites:
Consider also highlighting any noteworthy commonalities among the sites:
All 8 of the sites have real time control for their arterials and Fixed Route bus systems.

9. A Systems Engineering Approach
Key Messages:
The ICM ‘lifecycle’ follows the classic systems engineering process. You may be familiar with this “V” diagram [briefly review the steps].
The ICM Pioneer Sites recently completed CONOPS and Requirements. They are currently developing proposals to move from Requirements into high level design and implementation. 9 9

10. ICM AMS Focus: Integrated Performance Measures
Improved Corridor Management
In order to do ICM, you need to know what’s going on in the corridor, in the transportation network. To do that you need the data…. You need situational awareness. Next, you must be clear on what you want to measure in order to measure performance of the overall system. To know how, where, when and which ICM strategies to apply. You must have identified meaningful performance measures. Ultimately, you can do real time modeling and simulation to be proactive, not reactive… actively responding. This is ultimate vision of ICM--To achieve this, I need all 3 of these things—the right data (archived and real time), performance measures, and modeling and simulation tools to make that happen…
The ICM AMS vision includes the integration of not just physical assets (freeway, arterial, transit) but intellectual assets central to corridor management.
This vision begins with the establishment of multi-modal measures of system performance.
Data archiving strategies should focus on these multi-modal measures, and carefully monitored for data quality.
These data are the foundation for validated and trusted modeling and simulation activities supporting objective, performance-driven investment.
Predicted results from modeling and simulation are then verified by a subsequent round of measure refinement and field data analysis.
This improves both an understanding of corridor dynamics and the capability of simulation-based analyses to capture these dynamics.
Better data leads to better models leads to better investment, and so on.
Short-term prediction

11. Data Needs Analysis
ICMS introduces needs that were not present when we were only dealing with one network at a time.
Data collection needs time stamps so data from different sources can be aligned
Data granularity is different for ICMS (we need finer spatial and temporal detail)
Data latencies that were acceptable for reporting will not work for operational modeling and control
Decisions about how to respond to current situations should not be based on data that is days or weeks old.
Observational data needs to be collected often enough to represent the current situation.
Observational data needs to be available quick enough to facilitate a useful response
Challenges: Data sharing limitations: proprietary data, agency policies, incompatible data systems

12. ICM Data Requirements
Transit Networks - We need data that represents the current situation
Vehicle location and speed every seconds
Vehicle passenger count every pull-out
Arterial Networks – We need data that represents what is happening at the lane level
Vehicle volumes, by approach lane, collected every 1-5 seconds & reported every seconds
Signal phase data, by approach lane, collected every 1-5 seconds & reported every seconds
Link volumes and average speeds every seconds
As we worked with the pioneer sites, we realized that each had cetain data gaps with art and transit…most had decent f data…what kind of data is really needed to do icm…so we did some research…this is the results of that…we vetted with the sties and they concur that to do icm in real time you have to have this fidelity…

13. Corridor Performance Measures
Travel time
Travel delay time and predictability
Incident duration and frequency
Fuel consumption and pollution reduction
Corridor capacity utilization (vehicle & traveler throughput)

14. Sample ICMS Concept Key Messages:
Here is an example of an actual Concept Diagram from Montgomery County, MD.
The key message for me in this slide is that the left side, the ICM System (this should be highlighted a bit more), is developed by creating a few key capabilities: data collection, data processing, decision support, and performance management.  The system is enabled by connections to existing systems.  The site has also identified some additional capability that they want to add that should facilitate improved system performance: parking management, internal information distribution and public safety CAD system.

15. Multi-level Analysis Tools Provide Comprehensive Insight

We want to convey that we looked at the strategies in the first column with the intent of stressing the modeling approach with a focus on the items described in the right column.  For example, for the mode shift, we tried to test the pivot point method used between the macro model and the dynasmart-p meso model.   The key of the second column is the model and process tested.   17 17

18. Test Corridor AMS Overall ICM Benefit under Different Operational Conditions
Third, multi-modal measures of performance must have the support of all the major stakeholders in the corridor AND
be logically connected to data and modeling.
Measures that focus on mobility (travel time and reliability) as well as product (throughput) are required to fully characterize system performance.
The goal of the ICM AMS effort will be to deploy an analytical capability of long-standing value in each of the selected AMS sites that realizes the ICM AMS vision. 18 18

Key Messages:
This slide provides a high-level snapshot of San Diego. On the left is a map illustrating traffic flows and hotspots (the red dots) along the ICM Corridor during rush hour. The center images are photos of the same locations-the first one is the corridor today, without ICM. The right image is a modified image depicting the vision of ICM—managed lanes, park and ride, Bus Rapid Transit and convenient access to and from the arterial roadways—all managed as an integrated system by stakeholder agencies. 23 23

24. Dallas, Texas Key Messages:
This slide provides a visual of the Dallas TX corridor—on the left is a map with the corridor highlighted in yellow. The image is a photo of the corridor. 24 24

25. Minneapolis, Minnesota
Key Messages:
This is a snapshot of the Minneapolis corridor. On the left is a map of the corridor, color coded by jurisdiction—since with ICM, the corridor is managed as an integrated system, the MN team has identified the agencies with jurisdictional responsibility for various segments of the corridor to facilitate integrated operations. Next, we see an image of the corridor and on the right an image of the corridor during a road closure recently due to a truck turnover. In the future, these vehicles will be re-routed even earlier to arterials and transit options through a variety of traveler information channels (DMS, PDA, radio, etc.). 25 25
