In North America, agencies are applying rumble strips along the centrelines of undivided two-way roads to reduce crossover collisions. This practice appears to be limited due to a lack of published knowledge regarding design practices, site selection for installation, expected benefits, and possible difficulties. In addition, there are no national guidelines in North America for the installation of centreline rumble strips (CLRS). In Canada, three provinces (Alberta, Saskatchewan, and British Columbia) have implemented centreline rumble strips. In the United States, according to a survey conducted in 2003, 20 states have installed CLRS, and 18 states are considering installations. This paper summarizes the characteristics of current centreline rumble strip applications in Canada and internationally. A discussion of the safety effectiveness and potential concerns, such as maintenance and driver behaviour, as identified in current literature. Recommendations for the installation of CLRS are provided. For the covering abstract of this conference see ITRD number E211426.
