Crash Impact of Smooth Lane Narrowing with Rumble Strips at Two-Lane Rural Stop-Controlled Intersections - F50 CIS
(Free Publication) - As a low cost remedy to address crashes at unsignalized intersections on two lane rural roads, the Federal Highway Administration (FHWA) developed and evaluated a treatment to reduce approach speeds by narrowing lanes using rumble strips in the median and on the right lane edge. Following the acquisition of at least 2 years of post implementation crash data pre and post implementation crash analysis was conducted to compare the performance of the new treatments.
