Congestion has reached a boiling pointTransportation is part of the
public agendaCongestion is the No 1 political priority - Rep Young
…and people want more information to help them cope
In this past year….
• Dimensions of the problem
• What is required for “peak operating performance”
• Legislative Options

1980-1998
•Vehicle travel up 72%Road Miles up 1%
Dimensioning the Problem: Congestion
• 46% of peak period travel is congested
• 4.3 billion hours wasted
• No longer a big city problem– Congestion in small
areas grew 400%

Dimensioning the Problem:Incident Management
• 60% of the Peak?
• 1:4 clearance to traffic back up
• Cost of wrong response?
• Benchmarks?

Dimensioning the Problem: Work Zones
Top of American’s traffic frustration list!
American’s top three traffic improvements are work zone related.
1 of every 5 state miles in California is under construction!
Its not the money for Maintenance
It’s the time!
Dimensioning the Problem: Weather
• 50% of U.S population run 5% risk of hurricanes
• 69% of Americans in snow belt
• 74% of NHS in snow belt
•A day long weather shutdown - $15-$93 million
What is it going to take to achieve Peak Performance?
1. Raise the bar of individual activities
2. Integrate
3. Tools and data
4. Performance Measure
5. Communicate with the public
6. Spend the money
Peak Performance Raising the Bar
•Operations Self Assessment
•Signal Timing Video
•Incident Management Guidance
•Public Safety Initiative

Peak Performance Raising the Bar
• Work Zone Hassle Index
•Divides delay by life of improvement
•Integrating weather information with traffic signal timing
Peak Performance Integration
• Architecture Rule • The Long Range Plan for
Operations
• Required in 4 years
• Brings right players to table
• 511• Public will demand seamless
information
Peak Performance Tools
• Turbo Architecture
• IDAS
• Quick Zone

Peak Performance Measures
• 511 – DOT a phone call away
•Quality
•Accuracy
•Capacity
At least I called ahead and delayed the meeting
Peak Performance Communicate with Customer
Consider an award for the best traffic web site?
Peak Performance Spend the Money
• Baseline data• States relatively flat 5-6%
• Cities have grown from 3% to
nearly 7%
• Launched Survey• Are we spending enough?
• Does operations compete well?
Legislative Options
1. Data – Minimum data collecting capability on NHS
2. Institutional Development
3. Policy - Provide for three distinct missions
4. Money
Transportation is the Circulation System of our Communities
