| Abstract | Transverse rumble strips (TRSs) (also called in-lane rumble strips) have been used by some agencies to warn drivers in rural areas that they are approaching a stop sign. The strips typically consist of grooves crossing the roadway surface to provide a tactile and audible warning for drivers. Many studies have focused on the effect of TRSs on driver behavior, and there is some evidence that TRSs are effective in reducing the intersection approach speeds. However, the results from these crash-based studies are not reliable due to the lack of rigor in the accident evaluation designs. The objective of this effort was to examine the impact of TRSs on crashes, specifically total crashes, injury crashes, and specific crash types, such as right-angle and run stop sign crashes. The effort also included an economic analysis to investigate the tradeoffs between different crash types. Data on rural intersections with minor-leg stop control where TRSs were introduced was provided by the Iowa Department of Transportation (Iowa DOT) and Minnesota Department of Transportation (MnDOT). |
