Roads Around The World

Definitions
For purposes of international statistical comparison, the OECD defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels" which should include "bridges, tunnels, supporting structures, junctions, crossings, interchanges and toll roads but not cycle paths". In urban areas roads may diverge through a city or village and be named as streets, serving a dual function as urban space easement and route.
