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.
6-515: Palakkad Road , is an arterial road in Coimbatore , India . This road connects the city to Palakkad and the state of Kerala and the south-west suburbs in the Coimbatore metropolitan area . Palakkad Road is the main gateway into the city by road from Palakkad , Thrissur , Ernakulam and Walayar . This road is a part of National highways 544 (Salem - Kochin Highway) is now maintained by
12-898: The National Highways Authority of India . The L&T Bypass was opened in 2000 from Neelambur to Madukkarai, thereby decongesting the Palakkad road. The Western bypass is proposed as well to decongest the road. 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
18-518: The National Highways Authority of India . This road is a 7-km stretch of road running diagonally across the city in east–west orientation. Pollachi road starts near to Aathupalam in Karumbukkadai, and it passes through the important neighbourhoods of Kuniyamuthur , Marapalam and Madukkarai . The road is a two lane road in most stretches. The road was previously part of the NH-47 maintained by
24-485: 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
30-486: 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
36-453: 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
