1 US 75 Integrated Corridor Management Koorosh Olyai,, P.E. Assistant Vice President Dallas Area Rapid Transit ITS Texas September 5, 2008

2 Why ICM is needed in the US 75 Corridor DFW 5 th most congested region in US (#1 worst region for growth in congestion) DFW population is 6 million and adding 1 million every 8 years US 75 is a critical, regional corridor Travel demand and congestion continue to grow No ability to expand freeway, arterials, or alternate routes Other freeways are scheduled for construction Significant employers in corridor Numerous special events throughout year Showcase for ITS integration in the region

3 US 75 Corridor Networks US 75 Freeway with Continuous Frontage Roads HOV lanes on US 75 and IH-635 Dallas North Tollway 167 Miles of Arterials DART Bus Network Including Express Service DART Light Rail Red and Blue Lines

4 Description of Corridor Corridor Assets Diverse transportation infrastructure State-of-the-art freeway and frontage road system Recently completed 5-level interchange HOV, toll and SOV lanes Parallel arterials Two light rail transit lines Bus transit Management Centers 3 city TMCs state TMC transit TMC toll authority TMC

5 Corridor Summary Statistics Freeways with Frontage Roads High Occupancy Vehicle Facilities Light Rail Transit System (DART) Bus Transit System (DART) Dallas Signal System Plano Signal System Richardson Signal System Arterials Streets Park and Ride Lots (DART) Pedestrian / Bike Trails Tollways (NTTA) 272 Lane-miles 31 lane-miles 2 lines 20 stations 30 bus routes 500 signals 196 signals 120 signals 167 center-line miles 9 lots 12 miles 105 lane-miles

6 Dallas ICM Team Agency Partners: Dallas Area Rapid Transit (Lead) Cities of Dallas, Highland Park, Richardson, Plano, and University Park North Central Texas Council of Governments North Texas Tollway Authority TxDOT Dallas District Technical Support Team: Telvent Farradyne (Lead) Texas Transportation Institute Southern Methodist University University of Arlington

7 Regional Support for ICM Regional ITS MOU executed in 1999 Regional ITS Committees Will Provide Oversight Programmed Funding for Regional Integration Regional communication system Center-to-Center (C2C) plug-ins

8 Regional ITS Elements in Place Dallas Area-wide ITS Plan (1996, 2006 update) Individual agency ITS Plans Regional Architecture Regional Concept of Operations Regional Traveler Information Website Regional Telecommunication C2C Video and Data Sharing Regional Data Archiving Statewide interoperable tolling system

9 Regional ITS Elements in Place

10 Freeway System US 75 Corridor fully instrumented by 2007 New DalTrans Transportation Management Center Integrate TxDOT, DART, and Dallas County Sheriff s Dept CCTV Cameras Detection Systems Dynamic Message Signs With posted travel times Mobility Assistance Patrol

11 Arterial System Central Systems All signals connected C2C interface funded 911 Integration Surveillance cameras Video to wreckers Arterial DMS Freeway integration funded Traffic Signal Priority

12 DART Transit System (13 member cities) Light Rail Transit Park-and-Ride Lots Managed / HOV Lanes Bus System Local, Express Commuter Rail Connection Automated Vehicle Location Centralized Transit Control Passenger Alert System Transit Signal Priority 300 Member Transit Police

13 US 75 ICM Vision Operate the US 75 Corridor in a true multimodal, integrated, efficient, and safe fashion where the focus is on the transportation customer.

14 Physical Architecture

15 Dallas US 75 ICM Strategies Possible ICM Strategies: Performance measure approach Multi-modal and/or modal independent Common measures across agencies and jurisdictions Comparative measures shared with all agencies Improved traveler information and operational strategies to promote modal shift Enhanced data sharing among stakeholders and responders Development of sophisticated tools Modeling for evaluation Real-time modeling for operational prediction and optimization

16 Decision Support Tool

17 Dallas Goals for ICM Corridor Transportation Goals Increase corridor throughput Improve travel time reliability Improved incident management Enable intermodal travel decisions Community Goals Encourage business development Sustain economic activity Enable emergency services Source: FHWA Urban Congestion Report

18 Lessons Learned - Operational Only extra capacity in US 75 corridor is on rail transit Individual agencies operating their systems very well Operational opportunities exist with collaborative operation May require penalizing one user group to benefit overall corridor Example Freeway incident May require decreasing cross street arterial green time in favor of more arterial green time parallel to freeway for diverted trips Need for decision support tool to assess those operational trade-offs Need for better real-time arterial data

19 Lessons Learned - Institutional Good partnerships already in place Operational trust already exists from traffic management team, incident management cooperation, and HOV lane operation Build on existing agreements / MOUs Build on existing oversight ICM reports to existing Regional ITS Committee

20 Lessons Learned - Technical Need for enhancing regional data sharing Must accelerate existing data sharing projects already scheduled for region Need to determine methods for comparing and measuring multi-modal information Need additional detection for better real-time arterial data Travel times from toll tags may be most cost effective Need for detailed system engineering knowledge Developing Concept of Operations and System Requirements was system engineering intensive Use of consultants with experience was beneficial

21 Conclusions Individual agencies are operating their systems well Opportunities for advancement are in coordinated management Need alternatives for travelers, especially transit Need common, reliable data platforms for decision making Building on existing institutional arrangements was a key to building consensus Need to build trust with the public on accuracy and reliability of information
