1. Montgomery County Maryland I-270 Integrated Corridor Management Project Tom Jacobs, University of Maryland Center for Advanced Transportation Technology

2. 2 Operational – Why our Site needs ICM Overview of Corridor Transportation Network Infrastructure –I-270 Interstate & Arterial Network –WMATA Metrorail Network –WMATA Metrobus Network –Montgomery County DPWT Ride On Bus Network –MTA Maryland Rail Commuter (MARC) Network –MTA Commuter Bus (Hagerstown to Shady Grove)

3. 3 Operational – Why our Site needs ICM

4. 4 Summary of Operational Conditions –Primary commuting corridor for travelers within and outside of Montgomery County. Existing systems are already operating at or near capacity. Operational Needs Identified in the areas of: –Multi-modal Incident Management –Traffic Signal Operations –Transit and Commuter Management –Traveler Information –Infrastructure

5. 5 Operational – How ICM will help our Site Some key goals & objectives: –Optimize Mobility, Reliability, and Safety Improve travel predictability and reliability –Strengthen Corridor Level Decision Support Better data/info and tools for traveler and operations oriented decision making –Enhance Delivery of Reliable Real-time Information to Travelers Expand types of information, improve timeliness and delivery –Promote multi-modal system operations & use

6. 6 Institutional – Who are our ICM Stakeholders Core Maryland I-270 ICM Stakeholders: –Maryland Department of Transportation Maryland State Highway Administration Maryland Transit Administration –Montgomery County Department of Public Works and Transportation –Washington Metropolitan Area Transit Authority

7. 7 Institutional – How our Site defined Roles and achieved Buy-in among ICM Stakeholders Created Maryland I-270 ICM Steering Committee Representing Core ICM Stakeholder Agencies –Deliberately kept to smaller (more manageable) number Used Existing Regional Institutional Infrastructure for Project Coordination & Outreach –Metropolitan Washington Council of Governments Management, Operations, and ITS Subcommittee –Regional Operations Coordination Committee Institutionalizing Through Existing Infrastructure –Recently Created Metropolitan Area Transportation Operations (MATOC) Partnership

8. 8 Technical – What our proposed ICMS will look like Major Incident Scenario –Multi-vehicle crash including commercial veh’s SB I-270 @ Shady Grove I-270 ICMS Role –Notification –Verification & Information Updates –Decision Support Operations Travelers –Traveler Info –Post Incident Analysis

9. 9 Technical – How our ICMS will facilitate ICM Maryland I-270 Overview / Highlights –Built on Existing Regional Integrated Transportation Information System (RITIS) –New Systems / Subsystems & Interfaces Highlighted in Orange –Decision Support / Parking Management Subsystem / Systems Critical to Ultimate Success of ICM –Real-time Freeway & Arterial Data Critical Looking at Third Party Data Thru INRIX –I-95CC Contract requires delivery of mean travel time and speed every 5 minutes for freeways and arterials –Importance of getting real-time info to traveler via personal navigation devices cannot be underestimated

10. 10 Lessons Learned Institutional –Incorporate / include existing institutional infrastructure as much as possible –Embracing “multi-modal” approaches: desire is genuine, but easier said than done Operational –Improved operational efficiencies can be limited by capacity constraints –Multi-modal operational approaches will impact existing SOPs Technical –Requirements development: balance between requirements specification and design –External agency access to I-270 ICM data: different system development schedules for incorporating auto-mated data exchange is a challenge
