ACTIVE ARTERIAL MANAGEMENT (AAM)

Space Coast TPO ITS Master Plan Stakeholders’ Meeting

August 26, 2014

BACKGROUND

State Arterial Roadways

• 32,127 miles
• 160,515,000 vehicle miles traveled daily
• Current Arterial Problems:
• Increasing travel time delays
• Reduction in travel time reliability
• Non-recurring congestion caused by incidents,

special events, and roadway work zones

• Due to R/W constraints and construction funding,

improvement options are limited

BACKGROUND

Problem and Contributing Causes

• FDOT has a minimal role in the operations and

maintenance of the arterial system

• Local Agencies are responsible for the maintenance

and operations of the Signal Systems which significantly define the efficiency of the arterial system

• Currently, maintenance agreements (JPA) define the

responsibilities of the agencies

• The maintenance agreements are NOT tied to

performance measures and lack funding for adequate maintenance or operations

• All of the above has resulted in a lack of CPR

(Consistent, Predictable, Repeatable)

Active Arterial Management Flowchart

D4 Arterial Management Program

• Active Traffic Management (active signal retiming)
• Recurring congestion
• Non-recurring congestion from incidents (arterial &

freeway)

• Special Events & Work Zones
• Coordination with local responders
• Facilitate emergency maintenance needs
• Information dissemination
• Arterial Dynamic Message Signs
• FLATIS (pending)
• Palm Beach County – active October 2012
• Broward County – active February 2014

BRINGING AAM TO THE SPACE COAST

10

BENEFITS

• 1. Maximizes the investment that we have already made on the

roadways, ports, signal systems, ITS, etc.

• 2. Economic savings
• 3. Benefit to Cost Ratio of 16:1
• 4. Performance Measurement of the Arterial System

(Output & Outcome)

• 5. Reduced delays for ALL travelers
• 6. Improved travel time reliability
• 7. Reduced costs of delay to freight and transit
• 8. Improved real-time management of incidents, special events, or work

zones

• 9. Improved safety based on less stops at signals and reduced

secondary crashes

• 10. Improved environmental factors (reduction of air pollutants)
