An arterial road or arterial thoroughfare is a high-capacity urban road that sits below freeways / motorways on the road hierarchy in terms of traffic flow and speed . The primary function of an arterial road is to deliver traffic from collector roads to freeways or expressways , and between urban centres at the highest level of service possible. Therefore, many arteries are limited-access roads , or feature restrictions on private access. Because of their relatively high accessibility , many major roads face large amounts of land use and urban development, making them significant urban places.

As with other roadway environmental consequences derive from arterial roadways, including air pollution generation, noise pollution and surface runoff of water pollutants. Air pollution generation from arterials can be rather concentrated, since traffic volumes can be relatively high, and traffic operating speeds are often low to moderate. Sound levels can also be considerable due to moderately high traffic volumes characteristic of arterials, and also due to considerable braking and acceleration that often occur on arterials that are heavily signalized.
