Development of Guidelines for the Deployment of Flashing Yellow Arrow (FYA) Traffic Signals in Indiana – SPR#3725

摘要

The flashing yellow arrow has been proven to increase safety at signalized intersections that have one or more permissive left turns. There are, however, a variety of options for implementing such a signal. Researchers from Purdue University Calumet, through the JTRP partnership with INDOT, have reviewed these options and have created a draft policy for the state, including preferences for layout and controller programming. This draft policy and a review of expected issues and of the initial flashing yellow arrow in Indiana signals will be presented.
