Overview
• Traffic Congestion – How Do We Attack?
• Role of Transportation System Management and Operations
• Examples – What’s Possible using 21st Century Operations and 21st Century Technologies
3
Traffic Congestion Causes
RECURRING: Insufficient capacity Unrestrained demand Ineffective
management of capacity (e.g. poor signal timing)
NON-RECURRING: Incidents Work zones Weather events Special events Emergencies (e.g.
hurricanes)

How is the congestion pie sliced?
10%

Total delay: about 5 billion hours per year
Other recurring
Work ZonesOther non-recurring
e.g. special eventsPoor signal timing
Weather(snow, ice, fog)
Incidents (crashes, disabled vehicles)

Making a Difference: Long-term
Initiatives for Recurring Delay
• Build Additional Mainline Capacity
• Remove Bottlenecks
• Travel Demand Management
• Use Technology to Better Manage Traffic
6
Making a Difference: Short-term Initiatives for Non-Recurring Delay
• Implement Traffic Incident Management
Programs• Implement Work Zone Mobility Strategies
• Manage Weather-related Events• Manage Special Events• Provide Timely Traveler
Information

Work Zone Management
Strategies• Reduce Number and
Duration of Work Zones
• Improve Traffic Management in Work Zones
• Provide Travelers with Information and Options
10
Work Zone Management
Techniques• Work Zone Self-Assessments
• Federal Rule Making on Work Zone Management
• Full Road Closures
• Variable Speed Limits in Work Zones
11
Traffic Incident Management
Strategies• Establish Response and Clearance Procedures and
Policies
• Support Integrated Interagency Communications
• Institutionalize Traffic Incident Management
12
Traffic Incident Management
Techniques• Traffic Incident Management Self-Assessments
• Integrated Incident Management Systems
• CAD-TMC Operational Test
• Incident Management Coalition
13
Road Weather Management
Strategies• Develop accurate, real-time road
weather information
• Develop operator control strategies to minimize weather impacts
• Develop traffic management for adverse weather conditions
14
Road Weather Management
Techniques• NOAA/DOT Surface Weather
Partnership
• Maintenance Decision Support System
• Traffic Management Strategies
15
Dedicated Short Range Communications
• Electronic Toll Collection – 75 Percent Toll Lanes with ETC • Managed Lanes
• “WiFi Highway”
16
Transportation Management Centers
