Overview

Worldwide\, there is gro wing recognition and concern surrounding the impacts of human activity on the planet’s ecosystem. A broad spectrum of interests including pol itical leaders\, scientists\, environmental experts\, and individuals are seeking to reduce sources of global warming\, and the transportation engin eering/planning industry is being called to contribute solutions.

Providing increased efficiencies within existing pavement is a challenge f acing many agencies who are at the same time working with constrained budg ets. Efficient operation of traffic signals is an area where driver delay and emissions benefits can be realized. Relatively straight-forward activi ties such as optimizing traffic signal timing and choosing appropriate pha sing can be made at both existing and new traffic signals to minimize dela y and\, in doing so\, reduce emissions.

The Flashing Yellow Arrow protected/permissive left-turn (FYA PPLT) signal display is a relatively n ew traffic control device in the transportation engineering professionsâ €™ toolbox. The safety and operational benefits of the FYA display are well documented and the public reception has almost universally been posi tive. Agencies implementing FYA PPLT control are benefiting from both dela y and emissions reductions.

Use of the Flashing Yellow Arrow (FYA) at signalized intersections is a safe\, low-cost approach to reducing del ay and greenhouse gas emissions. This presentation highlights benefits and considerations supporting the use of FYA protected-permissive left-turn ( PPLT) signal control. A brief overview of the FYA PPLT control is presente d along with key implementation considerations. Washington County\, Oregon ’s effort to implement FYA PPLT at 372 locations is then profiled t hrough a case study that offers a sampling of the relative delay and green house gas emissions reduction achieved. This information should be of part icular interest to agencies exploring use of FYA PPLT control.

Ses sion attendees can expect to learn about:

• The difference b etween Flashing Yellow Arrow (FYA) &\; green ball indications\, as well as design considerations\;
• Benefits of converting from Pro tected to FYA left-turns\;
• Lessons learned from the Washingto n County experience\;
• Advanced signal control features to mak e permissive FYA’s safer and smarter\;
• Videos and case study discussions on the topic of FYA\; and
• An extended peri od for group discussion…come get your questions answered!

Th e TES workshop will start promptly at 12:30pm and will run until 2:30pm on Wednesday\, November 9th. There is no cost to attend this session and the workshop is equal to 2.0 professional development hours (PDH). Lunch will be provided.
