The Case for Color: Standardizing Red and Green Pavement Treatments for Exclusive Lanes

Bus lane and bike lane treatments have been increasingly adopted across the United States and abroad as transportation planners and traffic engineers try to boost emissions-reducing transit and bicycle ridership, improve safety for vulnerable road users, and improve the quality of streets for all road users. However, the execution of exclusive bus-only and bike-only lane treatments can vary widely, creating road user confusion and potential conflicts between private cars, trucks, transit vehicles, and bicycles vying for space within the limited right of way. Lack of uniformity is notable within some major metropolitan areas where bus- or bike-only lanes have varying delineation between municipal lines within the same corridor. This article provides a look at the work being done to develop uniform standards for bus-only and bike-only lanes (exclusive lanes), which would help to reinforce a clear understanding of these lanes to all road users to ensure their efficacy, to improve the travel time, and to improve user experience for bus riders and bicyclists.
