1. Traffic Congestion: Issues and Options Symposium June 26, 2003 Using Intelligent Transportation Systems (ITS) Technologies and Strategies to Better Manage Congestion Jeffrey F. Paniati Associate Administrator of Operations Acting Director, ITS Joint Program Office Federal Highway Administration

2. 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. 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) Traffic Congestion Causes

4. How is the congestion pie sliced? Incidents (crashes, disabled vehicles) Other recurring Weather (snow, ice, fog) Work Zones Other non-recurring e.g. special events Poor signal timing Total delay: about 5 billion hours per year

5. Making a Difference: Long-term Initiatives forRecurring Delay • Build Additional Mainline Capacity • Remove Bottlenecks • Travel Demand Management • Use Technology to Better Manage Traffic

6. Making a Difference: Short-term Initiatives forNon-Recurring Delay • Implement Traffic Incident Management Programs • Implement Work Zone Mobility Strategies • Manage Weather-related Events • Manage Special Events • Provide Timely Traveler Information

7. 21st Century Operations Proactive Customer view Regional system base 24/7 Performance based Real-time information 21st Century Technology Advanced Signal Control Ramp metering Work Zone Management Traffic Incident Management Real-Time Transportation (traveler) Information Emergency/Evacuation Management Freight Management In Short,… ITS Transportation System Management & OperationsImprove reliability, safety, and security through “21st Century Operations using 21st Century Technology”
