Abstract:

U.S. 285 is a major highway that runs through Colorado, New Mexico, and Texas with a large portion acting as a crucial corridor for the eastern portion of New Mexico, and also carries a significant portion of overturn crashes. Shoulder rumble strips are applied on both edges but these rumble strips are gradually deteriorated due to aging, traffic loading, and the change of weather. In order to reduce the potential and injury severities of overturn crashes, New Mexico Department of Transportation (NMDOT) District Two initiated a project and applied retroreflective rumble stripes with elements on existing rumble strips along U.S. 285 within NMDOT District Two jurisdiction to increase their visibility. In this project, retroreflective rumble stripes were applied by using high-durable acrylic traffic paint on existing rumble strips and then placing double drop dry elements to enhance the visual representation of edge line location as well as the angles associated with a rumble strip. With this project, this research is conducted to evaluate the safety performance of the newly implemented retroreflective rumble stripes in overturn crash occurrence prevention. In this study, a field survey was conducted to collect road users’ knowledge and opinion rumble strip and the implemented retroreflective rumble stripes regarding their safety effects, and 225 valid survey responses were collected for analysis. An empirical Bayes (EB) Before-after analysis was then conducted based on historical overturn crash data on U.S. 285 before and after the retroreflective rumble stripes were implemented. A safety performance function was trained based on crash and Annual Average Daily Traffic (AADT) data of U.S. 285. It is shown in the results that, on average, there is a 28.5% reduction in crash occurrences after the implementation of the retroreflective rumble stripes, indicating the effectiveness of this countermeasure in rural traffic safety improvement.
