Because of their length they have a role on very high-capacity routes, or as a component of a bus rapid transit scheme. Major examples of bi-articulated buses playing a major role in bus rapid transit can be found in Curitiba, Bogota, Mexico City, Quito, etc. Volvo is a major supplier of puller-type bi-articulated buses in these markets.[25] In the Netherlands, bi-articulated buses came into service in Utrecht (2002) and Groningen (2014) on busy routes.
