Arterial Roads: Provide a reasonably direct connection between multiple communities and major destinations and carry between 10,000 and 30,000 vehicles per day. They are typically spaced 800 to 1600 metres apart. Arterial roads make up much of the Primary Transit Network. Green infrastructure strategies may include vegetated swales, rain gardens, filter strips, and native vegetation. Bow Trail is an example of an Arterial Street.
Collector Roads: Connect lower volume local roads to arterial roads and generally serve transit. Daily traffic volumes range from 5,500 to 12,500. Primary collector roads may be divided or undivided, include or restrict parking, and have two or four travel lanes. Direct access from adjacent properties is usually restricted. A current example of a Collector is 5 Avenue N.W.
Local Roads: Provide direct access to abutting low and medium density residential properties. Access is not permitted to commercial properties because they are high traffic generators. Residential roads are low speed, low volume (less than 1,500 vehicles per day).
