1 San Diego I-15 Integrated Corridor Management Project Update Caltrans External Advisory Liaison (CEAL) July 16, 2014

2 2 OUTLINE 1.Background –Project Overview and Vision 2.ICM System 3.What’s happening now

3 3 Utilize technology and partnershipsUtilize technology and partnerships Manage corridor as systemManage corridor as system Provide travelers decision quality informationProvide travelers decision quality information Maximize corridor capacityMaximize corridor capacity 3 Arterial Signals Systems Freeway Systems Bus Systems Rail Systems USDOT ICM Vision Background

4 4 USDOT ICM Selected Eight Pilot Sites

5 5 Sabre Springs/Peñ̃asquitos Transit Center I-15 Express Lanes SR 56/Ted Williams Parkway N Direct Access Ramp (DAR) I-15 Main Lanes Express Lanes DAR BRT Stations Arterial Network Main Lanes ICM is about management of a corridor. Management implies more than monitoring. Management implies planning for, and responding to, what is happening across all networks Why ICM: Next Natural Step in TSM

6 6 I-15 ICM Vision Pro-actively Manage Congestion Provide Choices Maximize System Capacity Improve Coordination/ Interoperability

7 7 ICMS Context Diagram RAMS Signal timing plans Arterial Congestion Intersection status System alarms Local traffic advisories Regional Arterial Mgmt System RTMS Service change request Bus AVL Schedule Adherence Selected Stop/Route Data Panic alarms Regional Transit Mgmt System FMS CMS plans ELCS Request Freeway Congestion Freeway Incidents Travel Times Planned Events CCTV Imagery CMS Status Freeway Mgmt System Ramp Meter Information System REMS Usage Statistics Incident Detection Incident Details Intelligent Virtual Corridor TMC (User Screen) XML Data (3 rd Party Applications) Alert messages SPS Free spaces Area ID CPS RMIS LCS Meter Timing Plans Congestion Pricing System Toll Travel Times Events Lane Closure System Smart Parking System Regional Event Mgmt System CHP Transit Express Lanes Congestion Pricing Arterial Construction ATTS Arterial Travel Time System Arterial travel times Weather NWS Weather/NEXRAD NPS RTSS Network Prediction System Real-Time Simulation System Real-Time Data Predictions Evaluation MOE Real-Time Data Construction/Maint Status Metering Status Current Pricing/VTS signs EL Congestion One-way IMTMS interface Two-way IMTMS interface DSS control interface = New or Upgraded System 7 RTMS Service change request Bus AVL Schedule Adherence Selected Stop/Route Data Panic alarms Regional Transit Mgmt System RAMS Signal timing plans Arterial Congestion Intersection status System alarms Local traffic advisories Regional Arterial Mgmt System FMS CMS plans ELCS Request Freeway Congestion Freeway Incidents Travel Times Planned Events CCTV Imagery CMS Status Freeway Mgmt System

8 8 En-Route Traveler Information Pre-Trip Traveler Information Corridor Ramp Metering Signal Coordination on Arterials and Ramp Meters Enhanced Transit Network Information Pro-Active Corridor Congestion Management during recurring and incidents 8 DSS Operational Strategies Employed on I-15 with ICM

9 9 What’s Happening Now - DSS – ICM Response Plan Example

10 10 – What’s Happening Now – –Established Weekly Operational Review Meetings –Over 400 Response Plans Since April –Early May – Set to System Automation Approval –Operational Corridor Threshold Initiated 18% then to 8% (May 21 st ) –Released 511 – ICM App (May 9 th )

11 11 Getting to Integrated Operations Assets  Network and Routes  Systems and Capabilities  Availability Response Plans  Flexibility of Postures  Action Plans  Interagency Coordination 11

12 12 Posture Availability

13 13 Enhancements to serve as the corridor performance management element of DSS Future Existing Off-Line Modeling/Performance Analysis Predict Propose Evaluate Control Monitor Micro-simulation in real- time to predict and evaluate the response plans Business Rules to propose and monitor Workflow engines to control Decision Support System

14 14 Enhancements to serve as the corridor performance management element of DSS Future Existing Off-Line Modeling/Performance AnalysisPrediction Asset Availability Threshold Response Plan Evaluation Decision Support System System Supply/Demand –Arterials –Freeway –Express Lanes –Bus System Operations –Signals –Ramps –DMS –Barrier –Toll –511

15 15 What’s Happening Now - DSS – ICM Response Plan Example

16 16 16 Corridor Parameter ‘Tabs’ Regularly “Tweak” Corridor Score, Signal Response, Congestion Event Finder, Congestion Thresholds Occasionally Modify Global, Response Plan Expiration Timers, Asset Finder Not anticipated to change (rare) Strategy Matrix, Sim Q, Transit, Ramp Meter Simulation Hierarchy, Express Lanes Response Require Agency Oversight Asset Availability ICMS Corridor Configuration Tuning the System

17 Mobile Application - Release 17
