G8.1 Project title:
|
Traffic Signal Flashing Yellow Arrow (FYA) Conversion
|
|
G8.2 Project description: |
Convert existing traffic signals which operate protected only left turn phases to flashing yellow arrow (FYA) configurations to protected-permissive left turn phases. There are 17 intersections which will be modified with a total of 39 approaches being converted. The rationale is to reduce delay at intersections when gaps are available for drivers to make left turns. At some intersections, the permissive phase may only be operational during off-peak times.

G8.4 Purpose and need:
|
Purpose of the project is to reduce driver delay at intersections where gaps in opposing through traffic is available for drivers to make left turns. Some existing intersections were originally created as dual left turn lanes based on traffic projections which did not arrive and will be converted to single left turn lanes with the FYA project.

G13. Included in a CIP?
|
Yes
If funded, matching funds will be available through Overland Parks yearly Traffic Signals fund.

G14. Planning stage:

G15. Reviewed by state DOT?
|
No
|
|
G16. Right-of-Way acquisition: |
All acquired or none needed
|
|
G17. ROW by local public agency process manual?
|
No
|
|
G18. Other unique local goals and objectives?
|
Yes
Facilitate traffic flow along arterials. The FYA implementation is expected to result in a lower crash rate than standard permissive green ball left turns.
|
|
G19. Transportation Disadvantaged Population:
|
Disadvantaged populations will be equally affected as non-disadvantaged populations. All drivers will benefit from reduced delay at the traffic signals where protected-only left turn phases will allow for a permissive left turn phase.
|
|
G20. Relevant Public Engagement:
|
There was no public engagement for this specific project. When FYA conversion was new, public engagement was used to educate drivers how to react to FYAs. Anymore, FYAs are frequently requested by residents at existing traffic signals.
|
|
G21. Planned Public Engagement:
|
No public engagement is anticipated other than information that is currently on the citys website.

No
High-Intensity and More_Walkable Centers

|
G25. Environmental justice tracts?
|
Yes
A few locations that are proposed to be converted to FYA border an EJ tract. FYAs are expected to reduce vehicular delay into and out of those areas.
|
|
G26. Reduces greenhouse gas emissions?
|
Yes
Drivers are expected to be required to idle less at intersections after the conversion from protected-only left turns compared to when permissive left turn phases are enabled.
|
|
G27. Natural Resource information:
|
Existing ground is not anticipated to be disturbed during the project, as the project can be completed by modifying the existing traffic signal system.
|
|
G28. Community Links at Watershaed Scale:
|
|
|
G29. Explain local land use or comprehensive plans:
|
The OP Comprehensive Plan includes a section about the Overland Park Traffic Control System (OPTCS) which is used to coordinate traffic signal systems. The FYAs will provide OPTCS staff more flexibility with coordinating adjacent traffic signals.
