Click to edit Master title styleICM Toolbox

• ICM is about management of a corridor

• Management implies planning for, and responding to, what is happening across ALL networks

Why ICM: Change How We Manage ITS Assets

• Commitment - collaboration between various agencies, modes, and jurisdictions that transcends institutional boundaries

• All inclusive customer focus -Joint operational objectives and strategies to manage and balance the total capacity and demand of the corridor

• Sharing and distribution - of information and system operations control functions to support the analysis and immediate response

Overall ICM Strategies

• Implement Active Traffic Management (ATM):

• First in the nation real-time multimodal response and control (DSS System)

• Proactively manage multiple modes through and along the corridor

• En-route traveler information (CMS Signs, 511 San Diego mobile app)

• Pre‐trip traveler information (511 San Diego mobile app, 511 phone system)

• Signal coordination on local roadways with freeway ramp metering

• Transit rerouting

• Dynamic rerouting – November 2015

• Corridor ramp metering – November 2015 Predict

Congestion on north I-15 near Rancho Bernardo Rd. Consider alternate routes

inlcuding Exit at Ted Williams to Pomerado North and re-enter at Pomerado on

ramp.

Data along the response plan generated arterial route shows a clear increase in

vehicle flow. This increase in flow, however, shows no negative impact on the

speeds or travel times, as is demonstrated by INRIX data along Ted Williams

Pkwy and Pomerado Rd. Travel time remains relatively consistent to normal

day operations for that route. Reasons behind a lack of improvement in travel

time along the route could be attributed to weather conditions (rain and

thunderstorms) during that time frame. Heavy rainfal began approximately

around 2:30pm which is when the event was generated. Event did not trigger

until 3pm, however, once congestion had accumulated along the I-15 North.

Click to edit Master title styleSo What is Happening Now?

• SANDAG; Caltrans; cities of San Diego, Poway, and Escondido; NCTD; and MTS are working together

• ICM system allows partners to address congestion in real-time, holistically under ‘normal’ and incident conditions

• Alternate route signs are being installed on surface streets along the I-15 corridor to reroute motorists in the event of major incidents

31

Click to edit Master title styleLessons Learned: Institutional

• Follow Foundational Docs

• Consider Effort as a PATH with Time with your partners as the most valuable resource: Allows for presence-validation-understanding – perspective

• Operational Respectfulness/Constraints

• Individual and Group Discussions are Key

• Apply Existing and Traditional Principles

• We Don’t Know What We Don’t Know


32

Click to edit Master title styleLessons Learned: Technical

• Apply Technical Platform “V” Path

• Conduct a Requirements Walkthrough: Keep them honest!

• Explain Individually, Discuss as a Group: Requirements must be traced back to the original objectives, strategies and needs. Focus the group on where those requirements come from, and listen for where requirements are needed to provide the balance in approach.

• Data Requirements Extensive: Formatting | Size | Level of Integration

• Require Performance: make certain your requirements specify the Inputs | Functional Requirements | Outputs, but also ensure that key Performance metrics are a required.

• System Monitoring – Maintenance: Maintain project objectives | System Performance | System Enhancements etc.., relevant.

ICM Team Efforts Lead To Development of I-15 Corridor Management Team

• Long term corridor management vision

• Assess and analyze corridor management strategies

• Make actionable recommendations

The team will carry out a multi-modal platform that places emphasis on corridor performance monitoring and management to optimize overall corridor operations in an on-going basis and identify near-term, cost-effective solutions to get the most out of our transportation system. Efforts will serve as model for other corridors.

Next Steps:


34

Click to edit Master title styleI-15 Management Team Recommendations

• “Just Do It”• Modify existing Express Lanes signs

• Continue adjusting ramp meters to minimize GP Lane congestion

• Modify algorithm by increasing HOV ONLY density trigger

• Initiate effort to integrate CT and FasTrak detection systems

• Tier 1• Public information campaign to maximize potential customers

• Modify algorithm to delay pricing steps later in peak period

• Tier 2• Move Barrier to 3+1 configuration (Subject to GP Lane and

Express Lane Performance Measures)


35

Click to edit Master title styleNext Steps:

• Actions to Implement Plan

• Next ICM Corridors - Develop Next Concept of Operations

• Develop a TSMO

“Caltrans is dedicated to the ICM project because it is critical to enhancing the livability of I-15 commuters. The project’s success is due to collaborative, strategic partnerships of local, regional, and state agencies working in concert towards the common goal of providing network efficiency and reliability.”

Cory Binns, PE Chief Deputy District Director Caltrans District 11

“MTS bus dispatchers can effectively manage all local and commuter services in the I-15 corridor by using the ICM interface. Because the interface is comprehensive and includes current and predicted traffic, cameras, incidents, and other corridor information in real-time, we can manage our routing dynamically to get our passengers to their destinations in the quickest and most efficient way possible.”
