Why ICM is needed in the US 75 Corridor

• DFW 5th 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
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

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.
Physical Architecture
 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
Decision Support Tool
 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
                                Source: FHWA Urban Congestion Report
  – Enable emergency
    services
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
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
 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
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
