Rescot, R. A., Qu, S., Noteboom, R., & Nafakh, A. (2015). Evaluation of flashing yellow arrow traffic signals in Indiana (Joint Transportation Research Program Publication No. FHWA/IN/JTRP-2015/08). West Lafayette, IN: Purdue University. http://dx.doi.org/10.5703/1288284315530
The evaluation of flashing yellow arrow signals for widespread implementation was evaluated. Through the collection of field driver performance data, survey data, crash data, at two test sites in the State, it was concluded that this is a worthwhile practice to be considered for a larger scale deployment. The return on investment includes both increased safety, and improved mobility. Given Indiana’s widespread usage of span and catenary signal supports, installation could be simplified to place a larger four section flashing yellow head in a horizontal orientation while leaving adjacent through lane three section signal heads in a vertical alignment, and not decrease the standard of care provided to the public, given proper engineering judgment.
