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

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

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
