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.
5-463: Download coordinates as: Annerley Road is an arterial road in Brisbane , Queensland , Australia. It was formerly known as Boggo Road due to the boggy condition of the road. In 2013, a cyclist was killed when riding along Annerley Road. Annerley Road commences at Stanley Street at Clarence Corner . It passes through or forms the border of the suburbs of: It terminates at Ipswich Road at
10-697: The Annerley Junction. Annerley Road has many well-known landmarks including: Arterial road In traffic engineering hierarchy, an arterial road delivers traffic between collector roads and freeways . For new arterial roads, intersections are often reduced to increase traffic flow . In California, arterial roads are usually spaced every half mile, and have intersecting collector(s) and streets. The Traffic Engineering Handbook describes "Arterials" as being either principal or minor. Both classes serve to carry longer-distance flows between important centers of activity. Arterials are laid out as
15-485: The backbone of a traffic network and should be designed to afford the highest level of service , as is practical, as per the aforementioned "Traffic Engineering Handbook". The construction and development of arterial roads is achieved through two methods. By far the most common is the upgrading of an existing right-of-way during subdivision development. When existing structures prohibit the widening of an existing road however, bypasses are often constructed. Because of
20-486: The busier junctions. Speed limits are typically between 30 and 50 mph (50 and 80 km/h), depending on the density of use of the surrounding development. In school zones, speeds may be further reduced; likewise, in sparsely developed or rural areas, speeds may be increased. In western Canada, where freeways are scarce compared to the rest of North America, flashing early-warning amber lights are sometimes placed ahead of traffic lights on heavy signalized arterial roads so
25-453: The placement and general continuity of arterial road corridors , sewers, water mains, conduits and other infrastructure are placed beneath or beside the roadbed. In North America, signalized at-grade intersections are used to connect arterials to collector roads and other local roads (except where the intersecting road is a minor side street, in which case a stop sign is used instead). In Europe, large roundabouts are more commonly seen at
